Xylogenesis
Tree-ring anatomy, microdensity and isotope records provide valuable intra-annual information. However, extracting signals at that scale is challenged by the complexity of xylogenesis, where two major processes – cell enlargement and wall thickening – occur at different times and rates.
We characterized the space-for-time association in the tree rings of three conifer species by examining the duration, overlapping, inter-tree synchronicity and interannual stability during cell enlargement and wall thickening across regular tree-ring sectors (portions of equal tangential width).
The number of cells and cell differentiation rates determined the duration of sector formation, which augmented more rapidly throughout the ring for wall thickening than for enlargement. Increasing the number of sectors above c. 15 had a limited effect on improving time resolution because consecutive sector formation overlapped greatly in time, especially in narrow rings and during wall thickening. Increasing the number of sectors also resulted in lower synchronicity and stability of intermediate-sector enlargement, whereas all sectors showed high synchronicity and stability during wall thickening.
Increasing the number of sectors had a stronger effect on enhancing time-series resolution for enlargement- than for wall-thickening-related traits, which would nevertheless produce more reliable intra-annual chronologies as a result of the more similar calendars across trees and years in wall thickening

Chrysymenia wrightii, originally described from Japan, was found for the first time from the European Atlantic coast. It was collected in several subtidal rocky bottom habitats (9-14 meters depth) of the Ría de Arousa (Galicia, NW Spain). In this work, a description of Galician gametophytic and tetrasporophytic plants is provided. They are similar to the Mediterranean and Japanese plants. DNA sequence data of materials from Galicia and Korea were investigated using nuclear SSU and ITS1-5.8S-ITS2 rDNA and plastid rbcL sequences. No genetic variation was observed in the SSU, and only one substitution was detected in ITS and rbcL data between Galician and Korean samples, respectively. Our molecular data indicate that the Galician populations of C. wrightii are probably due to a recent introduction event from the northwest Pacific. Despite the fact that C. wrightii was formerly recorded as a new non-native species from a Mediterranean hotspot (Thau Lagoon, 1987-1989), it was never reported for the European Atlantic coast. After 30 years of its first report in the Mediterranean Sea, the simultaneous occurrence of C. wrightii in four subtidal localities of NW Spain suggests that this species may have colonized the region unnoticed for several years which may be related to its subtidal habitat and short life cycle. Similarly to the Mediterranean Sea, the introduction of C. wrightii on the European Atlantic coasts could be enhanced by the intensive aquaculture widely spread along the Galician coast. Curiously, C. wrightii is apparently restricted to both areas, the Ría de Arousa and the Thau Lagoon. In addition, many non-native species markedly represented in Galicia since the 1980’s were firstly reported in the Ría de Arousa. Consequently, the Ría de Arousa should be considered an outstanding European Atlantic hotspot of introduced marine species similar to the Solent region (South of England) or the Thau Lagoon.

El clima de La Habana favorece la presencia de hongos en el aire durante gran parte del año, principalmente en el horario diurno. En los períodos poco lluviosos (noviembre - abril) se evidencian las mayores variaciones climatológicas que pueden incidir en la severidad de enfermedades alérgicas y respiratorias. El objetivo de este trabajo fue caracterizar la micobiota atmosférica diurna de La Habana durante tres períodos poco lluviosos consecutivos. Se realizaron 48 muestreos volumétricos de propágulos fúngicos viables mediante un biocolector de rendija (colector chirana) durante tres períodos poco lluviosos (noviembre/2012-abril/2013, noviembre/2013-abril/2014 y noviembre/2014-abril/2015). Los hongos recolectados se aislaron e identificaron. Simultáneamente se realizó la identificación visual de esporas en las preparaciones procedentes de un captador tipo Hirst Lanzoni VPPS 2000, en el mismo día y hora de los muestreos viables. Posteriormente se calculó la concentración, densidad y frecuencia relativa de los propágulos fúngicos identificados por ambos métodos. Los períodos evaluados fueron similares de forma cuantitativa y cualitativa. Se identificaron 32 géneros fúngicos, tres sólo mediante cultivo, 17 sólo con metodología no viable y 11 con ambos sistemas de captación. También se identificaron esporas del orden Uredinales y de la familia Xylariaceae por el método no viable. Destacaron Cladosporium, Aspergillus, Penicillium, Fusarium y Curvularia por su abundancia y frecuencia relativa. La micobiota detectada en los tres períodos fue similar en diversidad y concentración de géneros. La temperatura media y la humedad relativa media se correlacionaron con las concentraciones atmosféricas de propágulos fúngicos. Los datos aportados son útiles para la prevención de alergias y enfermedades respiratorias, con alta incidencia en la población cubana en períodos invernales y secos
The climate of Havana favors a high representation of fungi in the air during the year, mainly in the day-time. In the periods of low rainfall (November to April), the greatest
climatic variations are evident, which can affect the appearance of allergic and respiratory diseases. The objective of this work was to characterize the atmospheric diurnal mycobiota of Havana during three consecutive dry periods. Forty-eight viable volumetric samples were obtained using a slit biocolector (chirana aeroscope) during three periods of low rainfall (November/2012-April/2013, November/2013-April/2014 and November/2014-April/2015). The collected fungi were isolated and identified. Simultaneously, visual identification of spores was conducted on the preparations from a Hirst type sampler (Lanzoni VPPS 2000), on the same day and time as the viable samplings. Subsequently, the concentration, relative density and relative frequency of fungal propagules identified by both methods were calculated. The three evaluated periods were quantitatively and qualitatively similar. Thirtyt two genera were identified, three genera only by viable methodology, 17 by non-viable and 11 by both methodologies. Spores of the order Uredinales and of the family Xylariaceae were also identified by the non-viable method. The genera Cladosporium, Aspergillus, Penicillium, Fusarium and Curvularia highlighted by their abundance and relative frequency. The mycobiota detected in both periods was similar in diversity and concentration of genera. Mean temperature and mean relative humidity were correlated with atmospheric concentrations of fungal propagules. The data provided are useful for the prevention of allergies and respiratory diseases, with a high incidence in the Cuban population during winter and dry periods

Stone-built heritage
The different organisms, ranging from plants to bacteria, and viruses that dwell on built cultural heritage can be passive or active participants in conservation processes. For the active participants, particular attention is generally given to organisms that play a positive role in bioprotection, bioprecipitation, bioconsolidation, bioremediation, biocleaning, and biological control and to those involved in providing ecosystem services, such as reducing temperature, pollution, and noise in urban areas. The organisms can also evolve or mutate in response to changes, becoming tolerant and resistant to biocidal treatments or acquiring certain capacities, such as water repellency or resistance to ultraviolet radiation. Our understanding of the capacities and roles of these active organisms is constantly evolving as bioprotection/biodeterioration, and biotreatment studies are conducted and new techniques for characterizing species are developed. This brief review article aims to shed light on interesting research that has been abandoned as well as on recent (some ongoing) studies opening up new scopes of research involving a wide variety of organisms and viruses, which are likely to receive more attention in the coming year

Combined laboratory and field research examining the possible alterations caused by herbicide treatments applied to the construction materials (schist and some granite, bound with mortar) in the Roman wall of Lugo (NW Spain), declared a World Heritage site by UNESCO in 2000, was performed in three separate studies in the past 20 years. In the summers of 1998 and 1999, the herbicides glyphosate, sulphosate and glufosinate–ammonium, as well as physical treatments (infrared and burning) were separately applied to different areas of the wall. In the spring of 2016, the oxyfluorfen herbicide Goal Supreme® was applied to test areas. In the winter of 2018, three essential oils, Origanum vulgare L., Thymus zygis Loefl. ex L., and Thymus vulgaris L., were each applied to test areas. Mineralogical modifications in the materials (determined by X-ray diffraction analysis), as well as visible physical changes, such as colour changes, and the appearance of saline residues were evaluated after the treatments. In the 1998/9 trial, glyphosate and both physical treatments triggered changes in the vermiculite clay minerals in the schists, and the physical treatments also caused changes in the kaolinite. None of the treatments caused highly perceptible colour changes. The oxyfluorfen herbicide did not cause any mineralogical alterations in the construction materials, but it did generate an increase in chloride, nitrate and sulphate contents of the granite and a slight darkening of this material. In the most recent study, the only deleterious effect observed was a perceptible increase in lightness and reduction in the yellow component after the application of Thymus zygis Loefl. ex L. essential oil to granite

Although numerous descriptive studies have been published throughout the 20th century on peat communities in the Southern Cone of South America, the nomenclature applied to the different units recognised often fails to take into account the proposals of previous authors. Our aim is to clarify the nomenclature by applying the rules of the ICPN to propose a current syntaxonomy of the class Myrteolo nummulariae-Sphagnetea magellanici. After a bibliographic compilation of possible peatland associations from the part of South America between parallels 40º and 56º south, under Temperate and Boreal macroclimates, we have collected around 30 names of phytosociological associations and alliances containing an abundance of homonyms and nomina nuda. Following ICPN standards, we have eliminated duplications and established priority names over others, lectotypified some names and rejected others as nomen ambiguum. We have arranged the floristic groups in the recognised associations in synthetic tables, with some nomina nudawhose characterisation we interpret as doubtful, as a proposed syntaxonomical organisation of the phytosociological class.The various communities recognised by the different authors who have worked in the territory can be divided into four physiognomic groups: 1. cushion bogs, 2. Sphagnumbogs 3. “montane tundra” bogs and 4. sedge-grass bogs. The syntaxonomic grouping we propose for the 13 associations recognised as nomenclaturally valid can be summarised as follows: a single class, Myrteolo nummulariae-Sphagnetea magellanici, is accepted, with a single order, Myrteolo-Sphagnetalia, and three alliances: Astelio pumilae-Oreobolion obtusanguli with seven associations (coinciding with type 1), Gaultherio-Sphagnion magellanici with four associations (type 2), and Abrotanello linearifoliae-Bolacion caespitosae with two associations (type 3). We contest the validity of around 22 names of syntaxa of different ranks, while acknowledging that more studies are required, particularly to define and delimit type 4 peatland communities
A lo largo del siglo XX se han realizado numerosos estudios descriptivos de comunidades turbosas por el Cono-Sur sudamericano, pero con frecuencia la nomenclatura aplicada a las distintas unidades reconocidas no tenía en cuenta las propuestas de autores anteriores. Nuestro objetivo ha sido clarificar la Nomenclatura aplicando las reglas del CINF para proponer una sintaxonomía de la clase Myrteolo nummulariae-Sphagnetea magellanici. Tras una recopilación bibliográfica de asociaciones de turberas de la parte de Sudamérica comprendida entre los paralelos 40º y 56º sur, bajo macroclimas Templado y Boreal, se han reunido alrededor de unos 30 nombres de asociaciones y alianzas fitosociológicas entre los que abundan homonimias y nomina nuda. Aplicando las normas del ICPN se han eliminado duplicidades, establecido nombres prioritarios sobre otros, lectotipificado algunos nombres y rechazado algún otro como nomen ambiguum. Los conjuntos florísticos de las asociaciones reconocidas, junto con algunas nomina nudacuya caracterización interpretamos como dudosa, se han reunido en tablas sintéticas como propuesta de organización sintaxonómica de la clase fitosociológica.La diversidad de comunidades que han reconocido los distintos autores que han trabajado en este territorio se puede repartir en 4 grupos fisionómicos: 1. turberas pulvinadas, 2. turberas esfagnosas 3. turberas de “tundra montana” y 4. turberas cipero-graminoides. La agrupación sintaxonómica que proponemos para las 13 asociaciones reconocidas como nomenclaturalmente válidas se resume en: una única clase Myrteolo nummulariae-Sphagnetea magellanici, con un orden único, Myrteolo-Sphagnetalia, y tres alianzas: Astelio pumilae-Oreobolion obtusanguli con 7 asociaciones

Outcrossing success
In Gentiana lutea two varieties are described: G. lutea var. aurantiaca with orange corolla colors and G. lutea var. lutea with yellow corolla colors. Both color varieties co-occur in NW Spain, and pollinators select flower color in this species. It is not known whether a hybridization barrier exists between these G. lutea color varieties. We aim to test the compatibility between flower color varieties in G. lutea and its dependence on pollen vectors. Within a sympatric population containing both flower color morphs, we analyzed differences in reproductive success (number, weight, viability and germinability of seeds) depending on fertilization treatments (autogamy and xenogamy within variety and among varieties). We found a 93% reduction in number of seeds and a 37% reduction in seed weight respectively of autogamy treatments compared to xenogamy crossings. Additionally, reproductive success is higher within color varieties than among varieties, due to a 45% seed viability reduction on hybrids from different varieties. Our results show that G. lutea reproductive success is strongly dependent on pollinators and that a partial hybridization barrier exists between G. lutea varieties.

Habitat type 9330,
The phytocenotic variability of the cork oak forests present in the northwesternmost Iberian Peninsula was studied through the analysis of a dataset of 145 new and 39 previously published relevés. The results allowed the recognition of four associations: (1) Arenario montanae-Quercetum suberis ass. nova: thermotemperate xerophytic forests of the Navia River valley (Galice/Asturias boundary); (2) Hedero hibernicae-Quercetum suberis stat. nov.: thermo-(meso-)temperate forests with oceanic influence of the Galician-Portuguese and Inland Galician territories; (3) Physospermo cornubiensis-Quercetum suberis: forests of the mesomediterranean territories of the Sil valley and Lower Bierzo, more thermic and less oceanic than the aforementioned communities; (4) Junipero lagunae-Quercetum suberis: mesomediterranean forests of areas of dry ombroclimate in the NE Portugal. Based on these results, a new interpretation is suggested for the Portuguese cork oak forests that have been considered as belonging to the typical subassociation of Physospermo cornubiensis-Quercetum suberis. The first two associations are part of the phytocenotic transition between the northernmost Mediterranean cork oak forests of the Iberian Peninsula and those present at the SW end of France. The new associations increase the knowledge of the phytosociological variability of habitat type 9330 of Annex I of CD92/43/EEC in the EU.

Especie amenazada
mapa de distribución
Población finícola
El pequeño helecho Cheilanthes guanchica, relativamente común en Andalucía e Islas Canarias fue descubierto
hace menos de 3 décadas en una pequeña población al sur de la provincia de Lugo, población que mostraba un
llamativo alejamiento con respecto al resto de las conocidas en la Península Ibérica. Aunque recientemente se
ha publicado un mapa de distribución que mostraba una presencia más numerosa de este helecho en localidades
de Castilla-León, e incluso otra localidad en Galicia, estudiando detenidamente las citas que respaldaban esas
presencias y su posible justificación con pliegos depositados en Herbarios, concluimos que ha habido numerosos
casos de confusión con otras especies, bien con Ch. maderensis, bien con Ch. acrostica. La localidad de donde
estimamos que procede la cita fiable más próxima a la gallega se sitúa a más de 420 km del sur de Lugo. La
población gallega de Ch. guanchica ocupa una superficie inferior a 1 km2 y muestra una competencia por su
mismo hábitat con Ch. tinaei, resultado de lo cual es la presencia del híbrido entre ambos Ch. ×insularis. Concluimos
que Ch. guanchica es una especie amenazada en Galicia por pequeño tamaño poblacional, aislamiento
geográfico e hibridación con Ch. tinaei.

The Sierra Madre Occidental mountain range (Durango, Mexico) is of great ecological interest because of the high degree of environmental heterogeneity in
the area. The objective of the present study was to estimate the biomass of
mixed and uneven-aged forests in the Sierra Madre Occidental by using Landsat-5 TM spectral data and forest inventory data. We used the ATCOR3 ® atmospheric and topographic correction module to convert remotely sensed imagery digital signals to surface reflectance values. The usual approach of modeling stand variables by using multiple linear regression was compared with a
hybrid model developed in two steps: in the first step a regression tree was
used to obtain an initial classification of homogeneous biomass groups, and
multiple linear regression models were then fitted to each node of the pruned
regression tree. Cross-validation of the hybrid model explained 72.96% of the
observed stand biomass variation, with a reduction in the RMSE of 25.47% with
respect to the estimates yielded by the linear model fitted to the complete
database. The most important variables for the binary classification process in
the regression tree were the albedo, the corrected readings of the short-wave
infrared band of the satellite (2.08-2.35 µm) and the topographic moisture
index. We used the model output to construct a map for estimating biomass in
the study area, which yielded values of between 51 and 235 Mg ha-1. The use
of regression trees in combination with stepwise regression of corrected satellite imagery proved a reliable method for estimating forest biomass.

Holocene environmental change on the Atlantic coast of NW Iberia as inferred from the Ponzos wetland sequence

The intertidal environment of the Ponzos beach (NW Iberian Peninsula) hosts a sedimentary sequence (including large wood fragments) deposited during the first half of the Holocene in a hygrophilous continental wetland. Pollen and macrofossil data alongside radiocarbon dating allow reconstruction of the changes that occurred during the Early and Middle Holocene in the landscape of the NW Iberia coastal lowlands, as well as the local wetland plant communities, in response to the climate variations and the eustatic sea-level oscillations. The sequence represents the evolution of a coastal wetland from its initial phases as a hygrophilous wetland towards the subsequent installation of a freshwater lagoon. Pollen data show the dominant role of Atlantic (mainly deciduous) woody taxa, the scarcity of conifers and the lack of Mediterranean elements in the coastal landscapes around the Ponzos site. The presence and abundance of some taxa such as deciduous Quercus, Castanea, Fagus, Tilia and Ulmus during the Early Holocene provides further support for the occurrence of glacial refuges in the Cantabrian-Atlantic area during the Last Glaciation. The diverse vegetation that characterizes the modern landscapes in this territory established later, spreading from these glacial reservoirs of biodiversity. In this sense, the notable and early presence of Fagus at the beginning of the Holocene, a tree also previously recorded during several phases of the Last Glacial Cycle on the NW Iberia coasts, is noteworthy. In addition, during the Early and Middle Holocene are recorded other trees that are currently extirpated as natural taxa in the area, such as Pinus, Tilia and Carpinus

There are certain saprophytic fungi in the soil able to develop an antagonistic effect against eggs of parasites. Some of these fungal species are ingested by animals during grazing, and survive in their feces after passing through the digestive tract. To identify and isolate ovicidal fungi in the feces of wild captive animals, a total of 60 fecal samples were taken from different wild animals kept captive in the Marcelle Natureza Zoological Park (Lugo, Spain). After the serial culture of the feces onto Petri dishes with different media, their parasicitide activity was assayed against eggs of trematodes (Calicophoron daubneyi) and ascarids (Parascaris equorum). Seven fungal genera were identified in the feces. Isolates from Fusarium, Lecanicillium, Mucor, Trichoderma, and Verticillium showed an ovicidal effect classified as type 3, because of their ability to adhere to the eggshell, penetrate, and damage permanently the inner embryo. Penicillium and Gliocladium developed a type 1 effect (hyphae attach to the eggshell but morphological damage was not provoked). These results provide very interesting and useful information about fungi susceptible for being used in biological control procedures against parasites

Colony Foundation in an Oceanic Seabird

Universidade de Santiago de Compostela. Departamento de Botánica
Seabirds are colonial vertebrates that despite their great potential for long-range dispersal and colonization are reluctant to establish in novel locations, often recruiting close to their natal colony. The foundation of colonies is therefore a rare event in most seabird species and little is known about the colonization process in this group. The Cory’s shearwater (Calonectris diomedea) is a pelagic seabird that has recently established three new colonies in Galicia (NE Atlantic) thus expanding its distribution range 500 km northwards. This study aimed to describe the establishment and early progress of the new Galician populations and to determine the genetic and morphometric characteristics of the individuals participating in these foundation events. Using 10 microsatellite loci, we tested the predictions supported by different seabird colonization models. Possibly three groups of non-breeders, adding up to around 200 birds, started visiting the Galician colonies in the mid 2000’s and some of them eventually laid eggs and reproduced, thus establishing new breeding colonies. The Galician populations showed a high genetic diversity and a frequency of private alleles similar to or even higher than some of the large historical populations. Most individuals were assigned to several Atlantic populations and a few (if any) to Mediterranean colonies. Our study suggests that a large and admixed population is settling in Galicia, in agreement with predictions from island metapopulation models of colonization. Multiple source colonies imply that some birds colonizing Galicia were dispersing from very distant colonies (> 1500 km). Long-distance colonizations undertaken by relatively large and admixed groups of colonizers can help to explain the low levels of genetic structure over vast areas that are characteristic of most oceanic seabird species

The analysis of plant macrofossils in peatland ecosystems has been widely used for the climatic and ecological reconstruction of the Holocene in the high latitudes of the northern hemisphere. By contrast, perhaps associated with rarity of these ecosystems, this proxy has barely been explored for southern Europe. In this work, a compilation and review of existing knowledge on the study of plant macrofossils of peatlands in southern Europe has been carried out, both from a paleoenvironmental perspective and in terms of biodiversity dynamics. Although small in surface area, the peatlands of southern Europe stand out for their diversity (botanical, edaphogenic, morphological, etc.), which has allowed the recovery of a large number of macrofossils from both vascular plants and bryophytes. The southern zone of Europe contains refuge zones with a high plant diversity that have not suffered the intense glaciation of the northern zones, this allows a continuous record since the beginning of the Holocene and the detection of climatic events in lower latitudes, where the ice recession was earlier.

We investigated how temperature patterns affect cambial activity and leaf phenology of oak across a wide range of natural woodlands at its southwestern distribution boundary. Understanding the climatic control of wood formation in dominant species is very relevant to infer tree responses to ongoing environmental changes and their impact on the carbon cycle. We selected nine sites along two elevation gradients from the coastline in northwestern Iberia, and sampled ten trees per site biweekly during 2012 and 2013. Leaf and cambial phenological phases were related to mean air temperature for 10–60 day running periods along the year to identify the most relevant time windows for cambium and leaf phenophases, and the relationships among them. The first earlywood vessels expanded before the appearance of small leaves, and subsequently underwent maturation to meet water requirements for full leaf unfolding. The advance or delay of cambial reactivation and budburst varied among sites and years modulated by spring temperature, and were respectively maximized by maximum and minimum values. Temperature can modify the onset of early phenophases of primary and secondary growth differently, and also the synchronicity between them. However, the maturation of the first earlywood vessels is necessary to undergo full leaf extension.

The pollen morphology of Gladiopappus vernonioides was studied with transmission (TEM) and scanning (SEM) electron microscopy and with light microscopy (LM). An Anthemoid pattern of exine ultrastructure was found. The pollen morphology of Gladiopappus supports the inclusion of this genus in the tribe Dicomeae and subtribe Dicominae but not in the Mutisieae s.str. The apertural system of G. vernonioides includes a mesoaperture that intersects the foot layer and the upper layer of the endexine, a condition already pointed out for several tribes of Asteroideae (Helenieae, Gnaphaliinae, Heliantheae, Inuleae, Senecioneae) and Carduoideae (Cardueae, Dicomeae). It is suggested that the existence of an intermediate aperture could characterize the apertural system of the Asteraceae as a synapomorphy

Se analiza la aparición del jacinto de agua (Eichhornia crassipes (Mart) Solms) en las playas del archipiélago de las Islas Cíes en el Parque Nacional Marítimo-Terrestre das Illas Atlánticas de Galicia, como resultado de un posible transporte a larga distancia procedente de poblaciones naturalizadas situadas en el litoral de Portugal. La especie, nativa de América del Sur, presenta una gran capacidad invasora, vinculada a su gran capacidad reproductiva y de crecimiento. Está incluida en el listado de IUCN de las 100 especies invasoras más dañinas del planeta. El Jacinto de Agua parece citado por primera vez en Europa en la zona centro de Portugal, durante la primera mitad del siglo XX, en donde se ha ido expandiendo principalmente por las cuencas de los ríos Tejo y Sado, aunque también se conocen poblaciones en la zona norte. En Galicia su presencia es testimonial y las escasas citas acreditadas, aparecen asociadas a la posterior erradicación de los ejemplares. Entre los años 2011 y 2012 y tras el paso de fuertes borrascas procedentes del suroeste, se detectó la presencia en una de las playas del archipiélago de las Islas Cíes de restos de Eichhornia crassipes, que en base a la gran cantidad de los mismos y su estado de conservación, hacen pensar en un transporte de larga distancia desde una población de gran tamaño
The arrival of Water Hyacinth plants (Eichhornia
crassipes (Mart) Solms.) at the beaches of theGalician
Atlantic Islands Maritime-Terrestrial National Park is
assessed as a consequence, of a long distance transport of
individuals coming from naturalized populations located on
the Portuguese coast. This South American native species
is highly invasive due to its fast growing and high
reproductive capacity. Water hyacinth is named by the IUCN
as one of the top one hundred of the world’s worst invasive
alien species. It was first cited in Europe during the first half
of the 20th century, in central Portugal, from where it has
expanded mostly throughout the catchments of Tejo and
Sado Rivers, although there are some other known
populations in the north of Portugal. Its presence is quite
exceptional in Galicia, being scarcely cited as it is normally
linked to eradication events. During 2011 and 2012, after
some SW squalls had passed by, some Eichhornia
crassipes (Mart) Solms. remains were detected in one of the
beaches of Cíes Island. Based upon the amount of plants,
and the deterioration degree of the remains, it is thought that
they have been transported from a big distant population

Se propone una fórmula de nomenclatura para las series de vegetación, de forma análoga a la empleada en la nomenclatura fitosociológica. Por otro lado, se propone un concepto de facies de serie de vegetación con base en su fisonomía, con ventaja sobre el concepto actual, que resulta ventajoso en la definición y cartografía de los paisajes.

The role and importance of a built structure are closely related to the surrounding area, with interest in a given area having a concomitant effect on the relevance given to the constructions it may hold. Heritage interest in landscape areas has grown in recent times leading to a sound valorisation process. This connects with the recent concept of biological cultural heritage (BCH), or biocultural heritage (definition still in process), that can be understood as domesticated landscapes resulting from long-term biological and social relationships. Although pastoral enclosures (in large part dry-stone walling, whose construction has been recognised by UNESCO as Intangible Cultural Heritage of Humanity since 2018) arise as traditional rural constructions linked with a way of life already disappearing, engaged local communities are recovering their biocultural value in terms of identity and positive conservation outcomes. In this sense, this article focuses on valuing traditional stone-built pastoral enclosures in two locations on the Atlantic coast of western Europe: Frojám (NW Iberian Peninsula) and Ladydown Moor (SW England). Findings concerning plant communities related to current or ancient pastoralism, and artefacts of built heritage are described, and an emphasis is placed on community engagement as a mechanism for conservation. The resilience of species-rich grassland communities is identified as a manifestation of biocultural heritage and an opportunity for habitat restoration. Finally, current trends and improvements in understanding of biological heritage and community conservation are addressed

Grey mould, powdery mildew, and downy mildew are the most frequent fungal diseases among vineyards worldwide. In the present study, we analysed the influence of the fungi causing these diseases (Botrytis, Erysiphe, and Plasmopara, respectively) on two viticulture areas from North-western (NW) Spain during three growth seasons (2016, 2017, and 2018). The obtained results showed the predominant concentration of the Botrytis airborne spores, mainly from the beginning of the Inflorescence emerge phenological stage (S-5) until the end of the Flowering phenological stage (S-6). Erysiphe and Plasmopara airborne spore peak concentrations were more localised around Flowering (S-6) and Development of fruits (S-7) phenological stages. We applied a Spearman’s correlation test and a Principal Component Analysis to determine the influence of the meteorological parameters on the concentration of airborne spores. Taking into account the variables with the highest correlation coefficient, we developed multiple regression models to forecast the phytopathogenic fungal spore concentrations. The Botrytis model regression equation explained between 59.4–70.9% of spore concentration variability. The Erysiphe equation explained between 57.6–61% and the Plasmopara explained between 39.9–55.8%. In general, we found better prediction results for mean daily concentrations than sporadic spore peaks

En el trabajo se realiza una caracterización de las
variaciones estacionales de la humedad del sustrato de los
brezales húmedos de la Serra do Xistral (Lugo, Galicia), y
se compara con la humedad de los diferentes ecosistemas
que forman la catena vegetacional en la que se enmarcan,
así como con la de otros tipos de humedales estacionales.
La representatividad de este territorio ha conllevado su
inclusión en la Red Natura 2000, mediante la designación
del Lugar de Importancia Comunitaria (LIC) Serra do Xistral
(ES1120015). Los datos presentados ponen de manifiesto
un funcionamiento ecológico homogéneo de los brezales
húmedos en relación al resto del complejo húmedo, así
como su funcionamiento inequívoco como ecosistemas
húmedos. Por tanto, se confirma el diagnóstico de los
brezales húmedos de las Sierras Septentrionales gallegas,
vinculados al tipo prioritario Nat-2000 4020*, incluido en el
Anexo I de la Directiva Comunitaria 92/43/CEE. El
diagnóstico y caracterización de los tipos de hábitat debe
considerar la estructura, composición y funcionalidad
ecológica, mediante el empleo de conocimientos científicos
y técnicos. Esto resulta de vital importancia, sobre todo para
la conservación de los tipos prioritarios, evitando la puesta
en marcha de planes y proyectos sin una adecuada
evaluación de sus repercusiones
In this paper we have performed a characterization
of the soil moisture in several wet heaths from Serra do
Xistral (Lugo, Galicia), to be compared with that in the
different ecosystems existing at the same vegetation catena,
as well as other seasonal wetlands in the region. The
representativeness of this territory has led to its inclusion in
the Natura 2000 network, by designating the Site of
Community Importance (SCI) Serra do Xistral (ES1120015).
The data presented show a homogeneous ecological
functioning of wet heaths in relation to the rest of the wet
complex, and sustain their unambiguous operation as wet
ecosystems. Therefore, it confirms the diagnosis of wet
heaths in the northern mountains of Galicia, linked to priority
type Nat-2000 4020*, included in Annex I of the EU Directive
92/43/EEC. The diagnosis and characterization of habitat
types should consider the structure, composition and
ecological functionality through the use of scientific and
technical knowledge. This is of vital importance, particularly
for the conservation of priority types, avoiding the
implementation of plans and projects without a proper
impact assessment

Se ha estudiado la producción y la germinación
de semillas de dos especies endémicas y amenazadas de
Galicia, analizando el efecto de la luz y del fuego (calor y
suelo quemado, cenizas), para tratar de averiguar si afectan
a su rareza. Armeria merinoi y Santolina melidensis
presentan una elevada producción de semillas sanas y una
germinación elevada y rápida, tanto en fotoperiodo como en
oscuridad, por lo que el mantenimiento de un banco de
semillas en el suelo, que contribuya al mantenimiento de las
poblaciones, parece poco probable. Las dos especies
difieren en su vulnerabilidad ante el calor de un incendio
forestal, comparable a la de otras especies estudiadas en
Galicia en Armeria merinoi, mayor en Santolina melidensis.
El efecto de las cenizas del suelo quemado sobre la
germinación de las semillas resulta también diferente en
ambas especies, puesto que en Armeria merinoi no afecta
ni al nivel ni al ritmo de germinación, mientras que en
Santolina melidensis sí, incrementándolos, lo que indica un
efecto fisiológico de las sustancias que puedan contener. El
fuego (temperatura) reduce la germinación de las semillas
de las dos especies, afectando a su viabilidad, favoreciendo
con posterioridad (suelo quemado) la rápida germinación de
las semillas viables restantes de Santolina melidensis
We studied seed production and germination of
two threatened endemic species from Galicia, analyzing
both light and fire (heat and soil burned, ash) effects, to
assess whether these factors affect their rarity. Armeria
merinoi and Santolina melidensis showed elevated healthyseed
production and high and fast germination, both in
photoperiod and darkness. Thus, the maintenance of a soil
seed bank contributing to maintaining populations seems
unlikely in the study species. Heat vulnerability during fire
events differed according to the species. Sensitivity in
Armeria merinoi is similar to what has been previously
reported for other species from Galicia. However, the
sensitivity observed in Santolina melidensis was higher. The
effect of adding ashes from burned soils also varied
between the species, in such way that germination rate and
level resulted affected in Santolina melidiensis, but not in
Armeria merinoi. This fact suggests the existence of
substances contained in ash, which can somehow affect
physiological processes.
Fire reduces initially seed germination and their viability in
both species, favouring a posteriori the fast germination of
the remaining viable seeds of Santolina melidensis via the
ashes in the burned soil

Flower color is an important characteristic that determines the commercial value of ornamental plants. Gentian flowers occur in a limited range of colors because this species is not widely cultivated as a cut flower. Gentiana lutea L. var. aurantiaca (abbr, aurantiaca) is characterized by its orange flowers, but the specific pigments responsible for this coloration are unknown. We therefore investigated the carotenoid and flavonoid composition of petals during flower development in the orange-flowered gentian variety of aurantiaca and the yellow-flowered variety of G. lutea L. var. lutea (abbr, lutea). We observed minor varietal differences in the concentration of carotenoids at the early and final stages, but only aurantiaca petals accumulated pelargonidin glycosides, whereas these compounds were not found in lutea petals. We cloned and sequenced the anthocyanin biosynthetic gene fragments from petals, and analyzed the expression of these genes in the petals of both varieties to determine the molecular mechanisms responsible for the differences in petal color. Comparisons of deduced amino acid sequences encoded by the isolated anthocyanin cDNA fragments indicated that chalcone synthase (CHS), chalcone isomerase (CHI), anthocyanidin synthase 1 (ANS1) and ANS2 are identical in both aurantiaca and lutea varieties whereas minor amino acid differences of the deduced flavonone 3-hydroxylase (F3H) and dihydroflavonol 4-reductase (DFR) between both varieties were observed. The aurantiaca petals expressed substantially higher levels of transcripts representing CHS, F3H, DFR, ANS and UDP-glucose:flavonoid-3-O-glucosyltransferase genes, compared to lutea petals. Pelargonidin glycoside synthesis in aurantiaca petals therefore appears to reflect the higher steady-state levels of pelargonidin synthesis transcripts. Moreover, possible changes in the substrate specificity of DFR enzymes may represent additional mechanisms for producing red pelargonidin glycosides in petals of aurantiaca. Our report describing the exclusive accumulation of pelargonidin glycosides in aurantiaca petals may facilitate the modification of gentian flower color by the production of red anthocyanins

The impact of climate on xylem structure and function has been profusely studied for a
variety of species in the last decades, but the ecological role of ring porosity under increasing levels of environmental stress has been scarcely assessed. In this study, we analyse the timing of earlywood vessels occlusions by tyloses in two ringporous species with contrasting ecological strategies (Quercus robur and Q. pyrenaica) along a seasonal drought gradient, and relate it to variations in earlywood vessel diameter and radial growth obtained from tree-ring series. The number of trees showing tyloses increased in summer as a result of more frequent cavitation events under drier conditions, and was more reduced for the more drought-tolerant Q. pyrenaica, which had a higher hydraulic diameter (Dh) but lower latewood increments. Dh values decreased towards the wettest sites, and were negatively related to warm and rainy conditions in winter. Our results showed that large earlywood vessel diameters are not necessarily accompanied by high rates of tyloses formation or limited growth in summer. We hypothesize that trees in seasonal environments can take advantage from large earlywood vessels, because benefits from a more efficient hydraulic system during favourable periods are higher than the risk of xylem impairment in summer.

En esta investigación se presenta una experiencia de aplicación de herramientas de
Sistemas de Información Geográfica a los módulos relacionados con el control de plagas en
dos ciclos formativos de la familia agraria. Los objetivos de este estudio han sido examinar
el efecto del uso de los SIG en el proceso de aprendizaje así como analizar las posibles
limitaciones de los resultados. Se ha empleado una metodología cualitativa basada en el
uso de cuestionarios sobre inteligencias múltiples, destrezas espaciales y seguimiento del
tema aplicados a grupos control (explicación sin herramientas SIG) y tratamiento
(explicación con herramientas SIG). Se ha constatado un impacto positivo de los SIG en el
aprendizaje significativo, ya que en términos generales los grupos tratamiento han acertado
más frecuentemente las cuestiones de interpretación espacial planteadas. Su carácter
motivador es manifiesto ya que la mayoría de alumnado ha solicitado realizar prácticas con
herramientas SIG y han sido capaces de identificar otros módulos en los cuales sería de
interés trabajar con estas herramientas. Algunas de las variables que han condicionado la
interpretación de los resultados son la duración de la experiencia, el número de cuestiones
planteadas y grado de dificultad de las mismas, así como que el tema planteado no se
centraba exclusivamente en aspectos de carácter espacial
In this research, we present an experiment applying Geographic Information Systems tools
(GIS) in pest management training of the Agrarian vocational training diplomas. The goals of
the study were examinating the effect of GIS use on the learning process as well as analyzing limitations of results. We used a qualitative methodology based on questionnaires
on multiple intelligences, spatial skills and following up on the topic applied to control groups
(explanation without GIS tools) and treatment groups (explanation with GIS tools). We
observed a positive impact of GIS on learning process, as in general, treatment groups
scored higher in the spatial questions proposed. A motivational effect was also observed, as
most students asked for practical training with GIS tools and students were able to identify
other subjects in which it would be useful working with these tools. Some variables may
have influenced the interpretation of results, such as the duration of the experience, the
number and complexity of the questions formulated, and that the focus of the topic was not
on geospatial issues

En este trabajo se revisan los principales
métodos de clasificación climática que han sido aplicados al
territorio gallego, haciendo especial énfasis en aquellos
orientados a explicar la relación entre parámetros climáticos
y la distribución de los vegetales sobre la superficie terrestre
(bioclimatología). Igualmente, se presentan por primera vez
expresiones cartográficas de detalle (macrobioclimas,
bioclimas, termotipos y ombrotipos) resultantes de la
aplicación de la “Clasificación Bioclimática Mundial” de S.
Rivas-Martínez a una base de 209 estaciones
meteorológicas de Galicia y territorios próximos. Según esta
clasificación bioclimática, la mayor parte del territorio de
Galicia se encuentra dentro del macrobioclima templado,
perteneciendo una proporción elevada del mismo a su
variante submediterránea, mientras que solamente el tramo
final de la cuenca del Río Sil y sus principales afluentes
(Bibei, Xares, Lor) pertenecen al macrobioclima
mediterráneo-pluviestacional. En cuanto al grado de
continentalidad, se puede considerar que la mayor parte de
Galicia presenta un clima poco contrastado (bioclimas
hiperoceánicos y semioceánicos), debido al efecto
modulador del mar. De esta tendencia se aleja únicamente
el extremo SE que se incluye en el bioclima semicontinental.
Los termotipos presentes en las áreas templadas son
termotemplado, mesotemplado, supratemplado,
orotemplado y criorotemplado, este último restringido a las
cumbres más elevadas del macizo de Trevinca-Sanabria;
dentro de las áreas mediterráneas se reconoce
exclusivamente el termotipo mesomediterráneo. Los
ombrotipos representados comprenden desde el
subhúmedo inferior al ultrahiperhúmedo, siendo dominantes
los de tipo húmedo (inferior y superior). Por último, se
discuten algunas cuestiones relativas a las limitaciones
derivadas de la red de estaciones meteorológicas empleada
así como la necesidad de su mejora para cubrir las
crecientes demandas de información relativas al
calentamiento global y su posible influencia en los hábitats
terrestres, especialmente en las áreas de montaña.

Mediterranean pine forests display high resilience after extreme climatic events such as severe droughts. However, recent dry spells causing growth decline and triggering forest dieback challenge the capacity of some forests to recover following major disturbances. To describe how resilient the responses of forests to drought can be, we quantified growth dynamics in plantations of two pine species (Scots pine, black pine) located in south-eastern Spain and showing drought-triggered dieback. Radial growth was characterized at inter- (tree-ring width) and intra-annual (xylogenesis) scales in three defoliation levels. It was assumed that the higher defoliation the more negative the impact of drought on tree growth. Tree-ring width chronologies were built and xylogenesis was characterized three years after the last severe drought occurred. Annual growth data and the number of tracheids produced in different stages of xylem formation were related to climate data at several time scales. Drought negatively impacted growth of the most defoliated trees in both pine species. In Scots pine, xylem formation started earlier in the non-defoliated than in the most defoliated trees. Defoliated trees presented the shortest duration of the radial-enlargement phase in both species. On average the most defoliated trees formed 60% of the number of mature tracheids formed by the non-defoliated trees in both species. Since radial enlargement is the xylogenesis phase most tightly related to final growth, this explains why the most defoliated trees grew the least due to their altered xylogenesis phases. Our findings indicate a very limited resilience capacity of drought-defoliated Scots and black pines. Moreover, droughts produce legacy effects on xylogenesis of highly defoliated trees which could not recover previous growth rates and are thus more prone to die

Estimating forest inventory variables is important in monitoring forest resources and mitigating climate change. In this respect, forest managers require flexible, non-destructive methods for estimating volume and biomass. High-resolution and low-cost remote sensing data are increasingly available to measure three-dimensional (3D) canopy structure and to model forest structural attributes. The main objective of this study was to evaluate and compare the individual tree volume estimates derived from high-density point clouds obtained from airborne laser scanning (ALS) and digital aerial photogrammetry (DAP) in Eucalyptus spp. plantations. Object-based image analysis (OBIA) techniques were applied for individual tree crown (ITC) delineation. The ITC algorithm applied correctly detected and delineated 199 trees from ALS-derived data, while 192 trees were correctly identified using DAP-based point clouds acquired from Unmanned Aerial Vehicles (UAV), representing accuracy levels of respectively 62% and 60%. Addressing volume modelling, non-linear regression fit based on individual tree height and individual crown area derived from the ITC provided the following results: Model Efficiency (Mef) = 0.43 and 0.46, Root Mean Square Error (RMSE) = 0.030 m3 and 0.026 m3, rRMSE = 20.31% and 19.97%, and an approximately unbiased results (0.025 m3 and 0.0004 m3) using DAP and ALS-based estimations, respectively. No significant difference was found between the observed value (field data) and volume estimation from ALS and DAP (p-value from t-test statistic = 0.99 and 0.98, respectively). The proposed approaches could also be used to estimate basal area or biomass stocks in Eucalyptus spp. plantations.

Se aportan datos sobre el biotopo y parámetros
demográficos de la única población conocida hasta este
momento de Culcita macrocarpa C. Presl. en la Provincia de
Lugo (Galicia, NW España). Los individuos se distribuyen en
tres subpoblaciones de tamaño desigual (19, 21 y 1 plantas)
que crecen entre los 460 y 500 m en ambientes sombríos al
lado de un curso de auga temporal que discurre por el
interior de un extenso robledal. En conjunto, la proporción
de individuos juveniles y adultos es muy semejante,
mostrando los ejemplares una elevada vitalidad, aunque
algo más del 10% de sus frondes están afectadas por la
pérdida de superficie fotosintética de origen desconocido.
Actualmente no existen factores de amenaza evidentes,
aunque la sustitución del bosque en el que se encuentra la
población estudiada por plantaciones de crecimiento rápido
o la intensificación del pastoreo podrían afectar
negativamente su conservación. Por esta razón, se propone
la declaración de un Espacio Natural Protegido en la cuenca
del Río Sor para asegurar la supervivencia de esta
población de un helecho protegido por su condición de
especie amenazada de extinción.

Phenology
Botrytis cinerea is the cause of the most common disease in the Galician and Portuguese vineyards. Knowledge of the spore levels in the atmosphere of vineyards is a tool for forecasting models of the concentration of spores in order to adjust the phytosanitary treatments to real risk infection periods. The presented study was conducted in two vineyards, one located in Cenlle (Spain) and other in Amares (Portugal), from 2005-2007. A volumetric trap, model Lanzoni VPPS-2000, was used for the aerobiological study. Phenological observations were conducted on 20 vines of three grape varieties in Cenlle (Treixadura, Godello and Loureira) and in Amares (Trajadura, Loureiro and Pedernã), by using the BBCH scale. The highest total spore concentrations during the grapevine cycle were recorded in 2007 in both locations (Cenlle:16,145 spores; Amares:1,858 spores), and the lowest, in 2005 in Cenlle (1,700 spores) and in Amares (800 spores) in 2006. In Cenlle, the best adjusted model was an ARIMA (0,2,2), including the relative humidity four days earlier, while in Amares there was an ARIMA (1,2,3), considering the relative humidity three days earlier and rainfall two days earlier. The t-test showed no significant difference between observed and predicted data by the model.

El trabajo realizado por los autores en estos últimos años en relación al estudio del género Isoetes L. ha
puesto de manifiesto la presencia de dos nuevas especies mediterráneas en territorio gallego. Así, el catálogo
actual del género en Galicia está constituido por 6 especies, entre las cuales se encuentran algunas catalogadas
como raras en su área de distribución natural, como Isoetes durieui o bien amenazadas como el endémico Isoetes
fluitans, de reciente descripción. La presencia de estas interesantes plantas, nos ha motivado a desarrollar una
clave con apoyo gráfico que facilite su identificación. Para cada una de las especies, se aportan además otros
datos de interés corológico, ecológico y fenológico.

Universidade de Santiago de Compostela. Departamento de Botánica
Después de los ensayos anteriores, de los que se hace un análisis histórico, de definir la diversidad de la vegetación gallega se propone una nueva ordenación basada en criterios actuales (florísticos, sucesionales, corológicos, respecto al Código de Nomenclatura Fitosociológica). El análisis se limita, en este caso, a las comunidades leñosas comprendidas en las clases Alnetea glutinosae, Calluno-Ulicetea, Cisto-Lavanduletea, Cytisetea scopario-striati, Pino-Juniperetea, Quercetea ilicis, Querco-Fagetea, Rhamno-Prunetea, Salicetea purpureae y Vaccinio-Piceetea, con un total de 65 asociaciones. Cada clase lleva una pequeña descripción que incluye su distribución en el territorio, las especies representativas y un comentario de sus afinidades con otras clases. Tras cada asociación aceptada se relacionan las tablas o grupos de inventarios gallegos que se asimilan a la misma con indicación del nombre originalmente osado y la referencia bibliográfica correspondiente.

Although aerobiological data are frequently used as a fl owering sign in phenological research, airborne pollen counts are infl uenced by a number of factors affecting
pollen curves. A study was made about the reproductive biology of birch and environmental factors infl uencing its pollen release and transport, in order to achieve a reliable
interpretation of Betula pollen curves. Aerobiological data were recorded in 2002 and
2003 at two sites in NW Spain and phenological observations were carried out on 20
trees from four Betula populations (three Betula alba L. and one B. pendula Roth.). Pollen production was calculated for six Betula alba trees. Chilling and heat requirements
for triggering development were calculated. Due to differences in the geographical location, budbreak and fl owering started fi rst in Betula pendula. The fl owering period lasted
from 8-13 days. Reduced pollen output per anther and catkin in individual trees in 2003
prompted a marked decline in overall pollen production. Major differences observed in
birch pollen curves were attributed to the infl uence both of weather conditions and pollen
transport from areas where the fl owering occurs at a different time. Heat requirements
calculated using phenological and aerobiological data were similar when the peak pollen-count date was used.

Predictive models
Alnus pollen is an early component of the annual atmospheric aerosol of the
north-west regions of Spain, which causes the first occurrence of allergic symptoms.
Seasonal and intra-daily variation of Alnus pollination, and the influence that main
meteorological parameters exert, was studied in this paper. Monitoring was carried out
from 1993–2002, by using two Lanzoni VPPS 2000 volumetric samplers. Once the
atmospheric behaviour of this pollen had been identified, the final objective was to
elaborate predictive models to determine the onset of the Alnus pollen season and its
concentrations during the pollination period in two localities of north-west Spain
(Santiago and Ourense). Winter chilling required to overcome the bud-dormancy period
was similar in both cities, with around 800 Chilling Hours (C.H.) and 5.5ºC threshold
temperature. Calculation of heat requirement for bud growth was carried out with
maximum temperature, with around 50 Growth Degree Days (G.D.D.ºC) needed, with
6ºC threshold temperature. Data from 2002 were used in order to determine the real
validity of the models. This year was not taken into account to establish the
aforementioned models. The variation between the predicted start of the pollen season
and the observed season was smallest in Ourense. Verifying the proposed models for
predicting daily mean concentrations of Alnus pollen during the pollen season shows
that the predicted curves fits the observed variations of daily mean concentrations.

Natural habitats are continuing to deteriorate in Europe with an increasing number of wild species which are also seriously threatened. Consequently, a coherent European ecological network (Natura 2000) for conservation of natural habitats and the wild fauna and flora (Council Directive 92/43/EEC) was created. Even so, there is currently no standardized methodology for surveillance and assessment of habitats, a lack that it is particularly problematic for those habitats occupying large areas (heathlands, forests, dunes, wetlands) and which require a great deal of effort to be monitored. In this paper we evaluate the changes affecting the European dry heaths (Nat-2000 4030) from the SCI Os Ancares–O Courel (Galicia, NW Spain) during the past decade. High-resolution aerial imagery analyses and Geographic Information Systems (GIS) were used. Losses of more than 7,000 ha (20.3%) of European dry heaths were computed during the 2003–2011 period in the SCI Os Ancares–O Courel, and also an increase of the degree of fragmentation was demonstrated for this habitat. Paradoxically, major impacts (afforestations, pasturelands) were financed by agri-environmental funds from the EU. Rather than promote biodiversity, these activities have provoked serious damages in this habitat of community interest, which is in complete opposition to the objectives of protection involved in the declaration of the SCI Os Ancares–O Courel

The assessment of habitat quality, especially in semi-natural managed systems, provides a powerful tool for monitoring short and long-term conservation actions. The Erica mackayana Atlantic wet heathlands of the Serra do Xistral protected area in Galicia, NW Spain, represent a dynamic system with high conservation value associated to traditional management through grazing of free-ranging cattle and wild ponies. Here, we aimed to develop a spatially-explicit, quantitative method for Habitat Quality Assessment, defining an optimum state and the alternative states that may arise from habitat degradation. Vegetation structure, grass-shrub cover ratio, gorse cover, presence of bracken, exotic species such as pine trees and saplings, erosive events and altered hydrological dynamics were identified as the main indicators of habitat degradation. A heterogeneous vegetation structure with a dominant shrub cover of c.a. 0.5 m height and constant gaps among shrubs, with a limited cover of gorse and absence of pine trees, bramble and bracken, and absence of erosive events was recognized as the optimum state. We applied the Habitat Quality Assessment (HQA) method to a pilot area within the Xistral protected site. Wet heathland was the dominant habitat, covering 37.1% of the area. 7.0% of the assessed heathlands were recognized as in the optimum state for habitat quality.Recommendations are made for habitat management to revert low scores, mainly by the adjustment of livestock numbers and the removal of exotic pine trees.
La evaluación de la calidad de hábitats constituye una herramienta muy útil para el seguimiento, a medio y largo plazo, de las acciones de conservación, especialmente en sistemas semi-naturales manejados. Los brezales húmedos atlánticos con Erica mackayana del espacio Red Natura Serra do Xistral, situado en Galicia, noroeste de España, representan un sistema dinámico con alto valor de conservación asociado al manejo tradicional mediante ganado vacuno y caballos salvajes. En este artículo desarrollamos un método cuantitativo y espacialmente explícito para la evaluación de la calidad del hábitat en brezales húmedos. Para ello definimos un estado óptimo y los estados alternativos que pueden resultar de la degradación del hábitat. Los principales indicadores de degradación que identificamos fueron la estructura de la vegetación, la proporción de cobertura de herbáceas-arbustivas, la cobertura de tojo, la presencia de helechos (Pteridium aquilinum), especies exóticas como los pinos, eventos erosivos y la existencia de dinámicas hidrológicas alteradas. El estado óptimo se definió como una estructura de la vegetación heterogénea, con una cobertura de arbustivas dominante de entorno a 0,5 m de alto y pasillos constantes entre las matas, con cierta cobertura de tojo, ausencia de pinos, helecho, eventos erosivos y alteraciones hidrológicas. Aplicamos la Evaluación de la Calidad de Hábitats a un área piloto dentro del espacio Serra do Xistral. Los brezales húmedos son el hábitat dominante y cubren el 37,1% del área de estudio. Un 7,0% de los brezales evaluados puntuaron como en estado óptimo. Se incluyen una serie de recomendaciones de manejo que permitan incrementar los valores de calidad de hábitats, ajustando la presión de ganado o la retirada de especies exóticas como el pino

A titularidade dos terreos incluídos nos espazos
naturais galegos foi mudando co paso do tempo. Nas
primeiras etapas, os espazos protexidos abranguían áreas
de escasa superficie de titularidade ou tutela públicas. A
partires da promulgación da política autonómica, o conxunto
de espazos naturais protexidos galegos aumentará a súa
superficie de xeito espectacular, sobre todo coa posta en
marcha da Rede Natura 2000, realizándose este incremento
fundamentalmente sobre territorios de titularidade privada. A
planificación destes espazos soamente será desenvolvida
de xeito heteroxéneo, acumulando prolongados retrasos e
conflitos na conservación e xestión dos compoñentes
naturais. Dende o ano 2007 ata a actualidade, as
declaracións de espazos de iniciativa municipal e privada
son as predominantes, executando os correspondentes
instrumentos de planificación os propios promotores dos
devanditos espazos, amosando unha maior axilidade e
eficacia no cumprimento dos prazos que os espazos de
tutela autonómica. Neste sentido, na actualidade estanse a
configurar novas ferramentas para a xestión e conservación
das áreas privadas, como a custodia do territorio, así como
se consolidan iniciativas para a declaración de espazos que
contribúan á conservación da biodiversidade e a promoción
do desenvolvemento sostible, como é o caso das Reservas
de Biosfera
The ownership of land included in Galician
protected areas was changing over time. In the early stages,
the protected areas ranged small areas of public ownership
or guardianship. From the enactment of regional policy, the
set of Galician protected areas increased its surface
dramatically, especially with the implementation of Natura
2000, being realized this increase mainly on privately owned
lands. The planning of these spaces will be developed only
so heterogeneous, accumulating long delays and conflicts in
the conservation and management of natural components.
Since 2007 until today, protected areas promoted by local
and private initiative are the predominant declarations,
running the corresponding planning instruments made by
promoters of these areas. They have showed a greater
agility and efficiency in meeting deadlines than public
regional guardianship protected areas. In this sense, today
new tools are being set up for the management and
conservation of private protected areas, such as land
stewardship, as well as initiatives to consolidate the
statement of spaces that contribute to the conservation of
biodiversity and the promotion of sustainable development,
as is the case of Biosphere Reserves

Medicinal plants are an ecosystem service directly implicated in human well-being. In many rural communities, they constitute a main treatment for disease or a source of disease prevention. Here, we review traditional knowledge of medicinal plants, the benefits they provide when cultivated in home gardens, and the determinants of knowledge about their uses in a rural parish in Amazonian Ecuador, where two ethnic groups prevail: indigenous Shuar and settled mestizos. Among 138 garden owners interviewed in 11 communities, a broad knowledge of 104 pharmacological properties across 145 medicinal plant species is retained. Several species play a specific role for a particular culture; therefore, the importance ranking of medicinal plants is different between the two main cultures. Traditional knowledge of medicinal uses is also influenced by ethnicity as well as generational age of the gardeners. Knowledge seems to have been lost in people of younger generations, who cultivated fewer species and knew less about properties of medicinal plants. Although men cultivate more diverse gardens, the role for women in the conservation of agrobiodiversity in home gardens appears crucial, as they are identified as the main source for transmission of traditional knowledge about medicinal plants. Our study highlights the importance of integrated land use management that respects different social aspects (i.e., culture, gender, health and well-being) related to conservation of biodiversity and traditional knowledge in agroecosystems.

Los parques urbanos son elementos de la infraestructura verde que deben contribuir a mejorar la calidad de vida y el bienestar
ciudadano. En este trabajo se presentan los resultados de la aplicación de un novedoso índice que estima la alergenicidad potencial
de las zonas verdes urbanas. Este índice, que contempla parámetros biológicos y biométricos intrínsecos a las especies arbóreas
existentes en los parques, genera un resultado cuyo valor está comprendido entre 0 y 1 según el potencial alergénico del parque
sea nulo o de riesgo alto para la población. En una primera fase el índice se ha aplicado a parques de diferente tipología, diseño,
tamaño, riqueza específica y biodiversidad ubicados en 20 ciudades españolas. Los resultados han mostrado que algunos de los
parques estudiados registran un valor de índice superior a 0,30, umbral suficiente para causar síntomas de alergia a la población
expuesta, y por tanto, de riesgo moderado o alto. Por el contrario, en la mayoría de los parques se obtuvo un valor inferior a este
umbral. También es posible conocer cuáles son las especies que más contribuyen al valor resultante, que son aquellas con estrategia
de polinización anemófila, periodos de floración extensos y alta alergenicidad referenciada. Estos requisitos los cumplen todas las
especies de las familias Betuláceas, Cupresáceas y Moráceas, y en menor extensión, Oleáceas y Platanáceas. Puede concluirse que
el desarrollo de un índice de estimación de alergenicidad de espacios verdes urbanos constituye una herramienta de utilidad para
minimizar el impacto de la alergia polínica en la población.
Urban parks are green infrastructure elements that should contribute to improving the quality of life and well-being of citizens.
In this work there are presented the results of applying a new index to estimate the potential allergenicity of parks located in 20
Spanish cities. This index, which considers intrinsic biological and biometric parameters of existing plant species in parks, allows
the allergenic risk thereof to be calculated on a scale ranging from 0 to 1, depending on whether to the park’s allergenicity is
zero or has a high risk for the population. The parks selected for this study have different typologies, sizes, species richness and
biodiversities, which has yielded highly variable index values. Almost half of the analysed parks have an index value higher than
0.30, a threshold considered having a moderate to high risk, and therefore, enough to cause allergy symptoms in the population.
Conversely, most of the parks had an index value below this threshold, so that the risk of suffering allergies is low or very low. The
formula also allows the species that most contribute to the resulting value for allergenicity to be known, which are those having
an anemophillous strategy of pollination, extended periods of flowering, and a referenced high allergenicity. These requirements
are met by all species of the Betulaceae, Cupressaceae and Moraceae families, and to a lesser extent by Oleaceae and Platanaceae.
It can be concluded that the development of an index to estimate the allergenicity of urban green spaces constitutes a useful tool
to minimize the impact of pollen allergy on the population.
Os parques urbanos são elementos da infraestrutura verde que devem contribuir para a melhoria da qualidade de vida dos
cidadãos. Neste trabalho apresentam-se os resultados da aplicação de um índice inovador, que permite estimar a alergenicidade
potencial dos espaços verdes urbanos. Este índice, que inclui parâmetros biológicos e biométricos, intrínsecos às próprias espécies
existentes nos parques, tem como resultado um valor numa escala entre 0 e 1, de acordo com o potencial alergénico do parque,
caso este seja, respetivamente e nos seus extremos, nulo ou de máximo risco para as populações. O índice foi aplicado em parques
de diferentes tipologias, desenho, tamanho, riqueza específica e biodiversidade, situados em 20 cidades espanholas. Os resultados
demonstram que alguns dos parques estudados registam um valor de índice superior a 0,30, limite suficiente para causar sintomas
de alergia na população exposta, e por tanto, risco moderado a alto. No entanto, a maioria dos parques apresenta um valor inferior a
este limite. Também é possível conhecer quais as espécies que mais contribuem para o valor do índice, que correspondem aquelas
com a estratégia de polinização anemófila, períodos de floração extensos e potencial alergénico referenciado. Estes requisitos são
aplicáveis a todas as espécies das famílias Betuláceas, Cupressáceas e Moráceas, e em menor medida, Oleáceas e Platanáceas. Pode
assim concluir-se que a aplicação de um índice de previsão dos níveis de alergenicidade dos espaços verdes urbanos constitui uma
ferramenta útil para minimizar o impacto da alergia polínica sobre a população.

This study aimed to analyze the biological effects of three new bioactive materials on cell survival, migration, morphology, and attachment in vitro. ACTIVA Kids BioACTIVE Restorative (Pulpdent, Watertown, MA, USA) (Activa), Ionolux (Voco, Cuxhaven, Germany), and Riva Light Cure UV (SDI, Bayswater, Australia) (Riva) were handled and conditioned with a serum-free culture medium. Stem cells from human dental pulp (hDPSCs) were exposed to material extracts, and metabolic activity, cell migration, and cell morphology were evaluated. Cell adhesion to the different materials was analyzed by scanning electron microscopy (SEM). The chemical composition of the materials was evaluated by energy-dispersive X-ray (EDX). One-way analysis of variance followed by a Tukey test was performed (p < 0.05). Ionolux promoted a drastic reduction in metabolic activity and wound closure compared to the control (p < 0.05), whereas Activa induced adequate metabolic activity and cell migration. Moreover, SEM and immunofluorescence analysis showed abundant cells exposed to Activa. The materials showed different surface morphologies, and EDX spectra exhibited different peaks of C, O, Si, S, Ca, and F ions in glass ionomer cements. The results showed that Activa induced cell migration, cell attachment, and cell viability to a greater extent than Riva and Ionolux.

Tropical forest
Over the past few decades there has been a growing realization that a large share
of apparently ‘virgin’ or ‘old-growth’ tropical forests carries a legacy of past natural
or anthropogenic disturbances that have a substantial effect on present-day forest
composition, structure and dynamics. Yet, direct evidence of such disturbances is
scarce and comparisons of disturbance dynamics across regions even more so. Here
we present a tree-ring based reconstruction of disturbance histories from three tropical
forest sites in Bolivia, Cameroon, and Thailand. We studied temporal patterns in tree
regeneration of shade-intolerant tree species, because establishment of these trees is
indicative for canopy disturbance. In three large areas (140–300 ha), stem disks and
increment cores were collected for a total of 1154 trees (>5 cm diameter) from 12 tree
species to estimate the age of every tree. Using these age estimates we produced
population age distributions, which were analyzed for evidence of past disturbance.
Our approach allowed us to reconstruct patterns of tree establishment over a period of
around 250 years. In Bolivia, we found continuous regeneration rates of three species
and a peaked age distribution of a long-lived pioneer species. In both Cameroon and
Thailand we found irregular age distributions, indicating strongly reduced regeneration
rates over a period of 10–60 years. Past fires, windthrow events or anthropogenic
disturbances all provide plausible explanations for the reported variation in tree age
across the three sites. Our results support the recent idea that the long-term dynamics
of tropical forests are impacted by large-scale disturbance-recovery cycles, similar to
those driving temperate forest dynamics.

Wood formation
Tree rings are natural archives of climate and environmental information with a yearly resolution. Indeed, wood anatomical, chemical, and other properties of tree rings are a synthesis of several intrinsic and external factors, and their interaction during tree growth. In particular, Intra-Annual Density Fluctuations (IADFs) can be considered as tree-ring anomalies that can be used to better understand tree growth and to reconstruct past climate conditions with intra-annual resolution. However, the ecophysiological processes behind IADF formation, as well as their functional impact, remain unclear. Are IADFs resulting from a prompt adjustment to fluctuations in environmental conditions to avoid stressful conditions and/or to take advantage from favorable conditions? In this paper we discuss: (1) the influence of climatic factors on the formation of IADFs; (2) the occurrence of IADFs in different species and environments; (3) the potential of new approaches to study IADFs and identify their triggering factors. Our final aim is to underscore the advantages offered by network analyses of data and the importance of high-resolution measurements to gain insight into IADFs formation processes and their relations with climatic conditions, including extreme weather events.

Introduction and objectives:
Powdery mildew caused by Uncinula necator and Downy mildew produced by Plasmopara viticola are the most common diseases in the North-West Spain vineyards. Knowledge of airborne spore concentrations could be a useful tool in the Integrated Pest Management protocols in order to reduce the number of pesticide treatments, applied only when there is a real risk of infection.
Material and Methods:
The study was carried out in a vineyard of the D. O. Ribeiro, in the North-West Spain, during the grapevine active period 2004–2012. A Hirts-type volumetric spore-trap was used for the aerobiological monitoring.
Results:
During the study period the annual total U. necator spores amount ranged from the 578 spores registered in 2007 to the 4,145 spores sampled during 2008. The highest annual total P. viticola spores quantity was observed in 2010 (1,548 spores) and the lowest in 2005 (210 spores). In order to forecast the concentration of fungal spores, ARIMA models were elaborated.
Conclusions:
The most accurate models were an ARIMA (3.1.3) for U. necator and (1.0.3) for P. viticola. The possibility to forecast the spore presence 72 hours in advance open an important horizon for optimizing the organization of the harvest processes in the vineyard

Iberian Peninsula
Peat accumulation
In the present study we reviewed the genesis, development and classification of peatlands in the Iberian Peninsula by conducting chronostratigraphic analysis of 108 of these ecosystems. The findings are summarised as follows: 1. The region has a wide variety of peatlands which are classified according to their biogeochemical, geomorphological and ecological characteristics into different types of bogs and fens.
2. Most of the peatlands occur in the Atlantic region followed by the Mediterranean and Alpine regions. Fens are more widely distributed than bogs, and blanket and raised bogs are mainly found in the Eurosiberian biogeographical region.
3. In many of the fens, the last active peat-forming cycle occurred during the Late Holocene (43 %). In most of the bogs, the peat-forming cycle occurred in the Middle Holocene (70 %), although in a substantial proportion of blanket bogs these processes occurred in the Early Holocene (30 %).
4. The peat formed in the last active cycle is, on average, thicker in raised bogs (322 cm) than in blanket bogs (257 cm) and fens (156 cm).
5. Vertical peat accumulation rates varied between 16 and 30 yr cm-1 in more than 40 % of the peatlands. The accumulation rates differed significantly between the different types of peatlands and were highest in the raised bogs. The accumulation rates were very variable in the fens.
6. The genesis, evolution and types of Iberian peatlands are similar to those observed in peatlands in northern latitudes in Europe and North America

In the present study, we analyzed the main parameters related with the potential fertilization ability of two grapevine varieties, Godello and Mencía, during the years 2017 and 2018. The research was carried out in two vineyards of the Galician winegrowing Designation of Origin areas of Ribeiro and Ribeira Sacra. Ten vines of each variety were selected for bunch and flower counting, pollen calculations, pollen viability studies by means of aceto-carmine (AC) stain and 2, 3, 5-triphenyl tetrazolium chloride (TTC) methods, and the determination of their germination rate. In all vineyards the 50% fruitset was reached, except for Godello in Cenlle during 2017. The mean coulure value was higher for Godello (40.5%) than for Mencía (31%). Analyzing the pollen production per plant and airborne pollen levels, we observed important discordances between them, which can be due to the influence of weather conditions and be related with self-pollination processes. We found important differences on pollen viability depending on the applied method and variety, with higher values for the AC method than the TTC for both varieties in all study plots, and higher values for Mencía variety than Godello. Regarding germination rates, we observed a marked reduction in 2017 with respect to 2018, in all study sites and for both varieties. The analyzed parameters were useful to explain the different productive abilities of Godello and Mencía varieties in the two studied bioclimatic regions of Ribeiro and Ribeira Sacra

Studies on the provenance of wood for shipbuilding contribute widely to the fields of archaeology, anthropology, environmental history, cultural geography, and palaeoclimatology. The development of reference datasets to determine the date and provenance of shipwreck timbers is therefore a paramount undertaking. Here we compile and present recent advances in the development of tree-ring chronologies, stable strontium isotope ratios and chemical biomarkers aimed to determine the date and provenance of Iberian shipwreck timbers. A set of oak and pine tree-ring chronologies have been developed from living trees covering the past 500 and 800 years, respectively, and have served to confirm the provenance of the wood used in an 18th-century Spanish ship of the Royal Navy. Stable strontium isotopic signatures have been obtained from soil and living trees at 26 sites throughout the Iberian Peninsula, providing a climate-independent geochemical network to source the origin of historic timbers. However, retrieving the original isotopic signature from waterlogged samples remains unsuccessful, stressing the need to develop effective protocols to separate the seawater signal from the original strontium isotope ratios in the wood. Analyses of organic compounds in wood of living trees have proven suitable to discriminate species and provenances, but results on shipwreck timbers are inconclusive and should be further explored. Our regional approach has the potential to be expanded to other areas and archaeological timbers from different periods throughout the Anthropocene. We highlight the strengths and weaknesses of the techniques presented when applied to waterlogged wood, propose GIS tools to interpret and visualize combined results, and stress the need to expand these type of reference datasets to allow for multiproxy dendroprovenancing approaches

Structure from Motion (SfM)
High spatial resolution imagery provided by unmanned aerial vehicles (UAVs) can yield accurate and efficient estimation of tree dimensions and canopy structural variables at the local scale. We flew a low-cost, lightweight UAV over an experimental Pinus pinea L. plantation (290 trees distributed over 16 ha with different fertirrigation treatments) to determine the tree positions and to estimate individual tree height (h), diameter (d), biomass (wa), as well as changes in these variables between 2015 and 2017. We used Structure from Motion (SfM) and 3D point cloud filtering techniques to generate the canopy height model and object-based image analysis to delineate individual tree crowns (ITC). ITC results were validated using accurate field measurements over a subsample of 50 trees. Comparison between SfM-derived and field-measured h yielded an R2 value of 0.96. Regressions using SfM-derived variables as explanatory variables described 79% and 86–87% of the variability in d and wa, respectively. The height and biomass growth estimates across the entire study area for the period 2015–2017 were 0.45 m ± 0.12 m and 198.7 ± 93.9 kg, respectively. Significant differences (t-test) in height and biomass were observed at the end of the study period. The findings indicate that the proposed method could be used to derive individual-tree variables and to detect spatio-temporal changes, highlighting the potential role of UAV-derived imagery as a forest management tool

The development of reliable methods for the estimation of crown architecture parameters is a key issue for the quantitative evaluation of tree crop adaptation to environment conditions and/or growing system. In the present work, we developed and tested the performance of a method based on low-cost unmanned aerial vehicle (UAV) imagery for the estimation of olive crown parameters (tree height and crown diameter) in the framework of olive tree breeding programs, both on discontinuous and continuous canopy cropping systems. The workflow involved the image acquisition with consumer-grade cameras on board a UAV and orthomosaic and digital surface model generation using structure-from-motion image reconstruction (without ground point information). Finally, geographical information system analyses and object-based classification were used for the calculation of tree parameters. Results showed a high agreement between remote sensing estimation and field measurements of crown parameters. This was observed both at the individual tree/hedgerow level (relative RMSE from 6% to 20%, depending on the particular case) and also when average values for different genotypes were considered for phenotyping purposes (relative RMSE from 3% to 16%), pointing out the interest and applicability of these data and techniques in the selection scheme of breeding programs.

Se revisan las diversas propuestas corológicas
que se han ido sucediendo a lo largo del último siglo para el
SW Europeo en general y el territorio gallego en particular,
así como los fundamentos teóricos sobre los que éstas se
sustentan. Teniendo en cuenta el estado actual de los
conocimientos sobre flora y vegetación en el extremo NW
Ibérico y los efectos que la dinámica paleoambiental
reciente (Pleistoceno-Holoceno) y la actividad humana han
tenido en este territorio, se propone una nueva
sectorización biogeográfica enmarcada en la propuesta más
reciente de Rivas-Martínez para la Península Ibérica. Como
aportación más novedosa de esta nueva sectorización
destaca la inclusión de la totalidad del territorio gallego
dentro de la Región Eurosiberiana, desestimándose la
existencia de territorios biogeográficamente mediterráneos,
tal y como había sido sostenido hasta el momento por
numerosos autores.

In recent years, North-western Spain has experienced an increase in the cultivated area of olive trees. The main propitious areas for olive groves are the Miño and Sil basins, as a consequence of their Oceanic climate with Mediterranean influence. The objective of this study is to determine the characteristics of reproductive biology, phenological and aerobiological behaviour of olive trees in the most northerly new plantation areas of the Iberian Peninsula. The study was carried out in an olive grove growing Olea europaea L. cv. ‘Arbequina’ located in Quiroga (Lugo) from 2016 to 2018. The phenological observations were based upon the main growth stages following the Biologische Bundesanstalt Bundessortenamt and Chemical industry (BBCH) scale. To predict the onset of flowering, a thermal time model was used in order to quantify the chill requirements, and growing degree-days were applied to determine the heat requirement. The production, viability and germination rates of Olea pollen were evaluated from samples selected in nine individual trees for the phenological survey. The aerobiological study was conducted by means of a Hirst-type pollen trap located in the centre of the olive grove. The vegetative period of the olive tree in the study area lasted an average of 259 days. The important phenological stage 6 (flowering) was the shortest stage. An average of 704 Chilling Hours (CH) with a threshold of 2.5 °C was required to overcome the chilling period, 1139 Growing Degree Days (GDD) for the beginning of flowering, and 4463 GDD for harvest. The pollen production per anther was 82589 grains (± 14084 pollen grains), with a rate of 81% viability and 12% pollen tube germination. The main pollen season started on average on May 20th and ended on June 16th with an average duration of 27 days and an annual pollen integral of 833 pollen grains. The low pollen concentrations could be a consequence of the Northern location of the forest, in a bioclimatic transition zone between the Eurosiberian and the Mediterranean areas, at the limit of olive tree distribution

Live/dead fuel fractions

Simultaneous fitting
Fuel load additivity
Stand level equations
Forest fuel loads and structural characteristics strongly affect fire behavior, regulating the rate of spread, fireline intensity, and flame length. Accurate fuel characterization, including disaggregation of the fuel load by size classes, is therefore essential to obtain reliable predictions from fire behavior simulators and to support decision-making in fuel management and fire hazard prediction. A total of 55 sample plots of four of the main non-tree covered shrub communities in NW Spain were non-destructively sampled to estimate litter depth and shrub cover and height for species. Fuel loads were estimated from species-specific equations. Moreover, a single terrestrial laser scanning (TLS) scan was collected in each sample plot and features related to the vertical and horizontal distribution of the cloud points were calculated. Two alternative approaches for estimating size-disaggregated fuel loads and live/dead fractions from TLS data were compared: (i) a two-steps indirect estimation approach (IE) based on fitting three equations to estimate shrub height and cover and litter depth from TLS data and then use those estimates as inputs of the existing species-specific fuel load equations by size fractions based on these three variables; and (ii) a direct estimation approach (DE), consisting of fitting seven equations, one for each fuel fraction, to relate the fuel load estimates to TLS data. Overall, the direct approach produced more balanced goodness-of-fit statistics for the seven fractions considered jointly, suggesting that it performed better than the indirect approach, with equations explaining more than 80% of the observed variability for all species and fractions, except the litter loads

Socioecological research
The 11th Conference of the Spanish Association of Terrestrial
Ecology, held in Pamplona, Spain, on 6–10 May 2013,
included a symposium on alpine ecological research in the
Iberian Peninsula. This session offered an excellent
opportunity to assess the state and progress of alpine ecology
in this region, identify knowledge gaps, and discuss further
directions for research. Iberian alpine ecosystems are
biodiversity hotspots and have traditionally contributed to
sustaining rural livelihoods. Today, these ecosystems are
subjected to large changes in land uses, including land
abandonment, and are affected by climate change. This article
reviews the current state of Iberian alpine ecology and
proposes a research agenda. Alpine ecology in the Iberian
Peninsula is a growing field of research. The need for larger
spatial and temporal scales in research and monitoring, along
with the integration of socioecological aspects, is a critical
issue for understanding the major drivers of change in the
alpine ecosystems of the Iberian Peninsula. The
implementation of effective mitigation strategies aimed at
reducing the impact of the pressing environmental and
socioeconomic problems of Iberian mountain areas can only
be accomplished through a multidisciplinary and integrative
approach.

Palaeoenvironmental reconstruction
The northwest region of the Iberian Peninsula is home to a unique ecosystem of bogs, which are particularly sensitive to projected climate change. In this context, the rate of carbon (C) accumulation in Chao de Veiga Mol, an intact raised bog, was analysed. Changes in the accumulation rate over the past 10 millennia were determined in a peat core of 847 cm in depth, with a high mean rate of peat growth (11 yr cm−1, 0.09 cm yr−1). An age-depth model was generated from 22 14C dates and fallout radionuclides. Chronological, stratigraphical and physico-chemical data confirmed the existence of a single cycle of peat formation throughout the Holocene and the formation of ombrotrophic peat 9500 years ago. The total mean C content was 50.2%, and over 10 millennia 583 kg C m−2 accumulated at a mean rate of 35.3 g C m−2 yr−1, with a long-term (apparent) rate of carbon accumulation in the catotelm of 59.9 g C m−2 yr−1. These values are much higher than reported for other Iberian peatlands and are amongst the highest documented for peatlands in the northern hemisphere. The dynamics of C accumulation and other measured parameters reveals important variations throughout the Holocene. They could be associated with the main climatic events described in the northern hemisphere and are highly consistent with models established for northern latitudes. The Chao de Veiga Mol raised bog is unique and of great potential value for carrying out high resolution palaeoenvironmental studies, especially in relation to regional and local modulations in southern Europe.

Flower color variation among plant populations might reflect adaptation to local conditions such as the interacting animal community. In the northwest Iberian Peninsula, flower color of Gentiana lutea varies longitudinally among populations, ranging from orange to yellow. We explored whether flower color is locally adapted and the role of pollinators and seed predators as agents of selection by analyzing the influence of flower color on (i) pollinator visitation rate and (ii) escape from seed predation and (iii) by testing whether differences in pollinator communities correlate with flower color variation across populations. Finally, (iv) we investigated whether variation in selective pressures explains flower color variation among 12 G. lutea populations. Flower color influenced pollinator visits and differences in flower color among populations were related to variation in pollinator communities. Selective pressures on flower color vary among populations and explain part of flower color differences among populations of G. lutea. We conclude that flower color in G. lutea is locally adapted and that pollinators play a role in this adaptation.

Durante una de las fases del trabajo de
campo que estamos realizando sobre el estudio
de la estructura, composición florística y conservación
del bosque de ribera a lo largo del río
Navia (Lugo), hemos recolectado entre otras,
una especie de la familia de las escrofulariáceas
que identificamos como Lathraea squamaria L.
La especie, que no había sido citada de Galicia
hasta la fecha (Planellas, 1852; Meri no,
1905-1909; Niño Ricoi et. al., 1994; Romero,
2008), tampoco se conoce del vecino Portugal
(Sam pai o, 1946; Pereira Coutinho, 1974;
Amaral Franco, 1984).

Selective pressure along a latitudinal gradient affects subindividual variation in plants

Individual plants produce repeated structures such as leaves, flowers or fruits, which, although belonging to the same genotype, are not phenotypically identical. Such subindividual variation reflects the potential of individual genotypes to vary with micro-environmental conditions. Furthermore, variation in organ traits imposes costs to foraging animals such as time, energy and increased predation risk. Therefore, animals that interact with plants may respond to this variation and affect plant fitness. Thus, phenotypic variation within an individual plant could be, in part, an adaptive trait. Here we investigated this idea and we found that subindividual variation of fruit size of Crataegus monogyna, in different populations throughout the latitudinal gradient in Europe, was explained at some extent by the selective pressures exerted by seed-dispersing birds. These findings support the hypothesis that within-individual variation in plants is an adaptive trait selected by interacting animals which may have important implications for plant evolution.

Ring-porous wood
crown water status
A quantitative method was tested to describe crown phenophases in relation to water content and to secondary growth in ring-porous species, based on the hypothesis that new shoots require hydrated tissues to maintain the necessary turgor for extension, leading to a reduction in dry matter content (DMC). We collected a three-year-old branch from 11 Quercus pyrenaica Willd. trees at 10-day intervals to estimate DMC of newly developing buds, leaves, and twigs, and processed two opposite stem microcores for xylogenesis. Branch phenophases and shoot length were recorded in the field. The DMC of all organs decreased during crown development, with a minimum in early June, followed by a gradual increase up to initial values in late September. The shoot extension period concurred with the lowest DMC, but also with the beginning of earlywood maturation in the main stem, suggesting a high tissue hydration only when earlywood vessels become functional to fulfill enough water requirements for shoot and leaf extension. These results confirm the usefulness of DMC to accurately quantify the phenology of primary growth from bud swelling up to full leaf extension, as a complement to qualitative methods. This variation in DMC appears to be linked to secondary growth as a result of earlywood vessel development.

Neste traballo avalíase a importancia botánica para a conservación da contorna da Fraga de Sto. Estevo
do Ermo, situada no concello de Barreiros (Lugo, NW España). Dentro das 331 ha que comprende este espazo, identificáronse un total de total de 219 taxons de plantas vasculares, das que 19 (8,6% do total) son Pteridófitas. Seis taxóns, entre eles os fentos Dryopteris aemula, Vandenboschia speciosa e Woodwardia radicans, son especies protexidas cuxas poboacións locais están asociadas ás 15,2 ha que ocupan os 6 tipos de hábitat do Anexo I da DC 92/43/CEE (dous deles de carácter prioritario) recoñecidos na área de estudo. A pesar da reducida superficie que ocupan estes ambientes ecolóxicos,
este enclave pode cualificarse como un lugar de gran relevancia para a conservación das pteridófitas a nivel rexional

A multi-sensor and multi-scale monitoring tool for the spatially explicit and periodic monitoring of eutrophication in a small drinking water reservoir is presented. The tool was built with freely available satellite and in situ data combined with Unmanned Aerial Vehicle (UAV)-based technology. The goal is to evaluate the performance of a multi-platform approach for the trophic state monitoring with images obtained with MultiSpectral Sensors on board satellites Sentinel 2 (S2A and S2B), Landsat 8 (L8) and UAV. We assessed the performance of three different sensors (MultiSpectral Instrument (MSI), Operational Land Imager (OLI) and Rededge Micasense) for retrieving the pigment chlorophyll-a (chl-a), as a quantitative descriptor of phytoplankton biomass and trophic level. The study was conducted in a waterbody affected by cyanobacterial blooms, one of the most important eutrophication-derived risks for human health. Different empirical models and band indices were evaluated. Spectral band combinations using red and near-infrared (NIR) bands were the most suitable for retrieving chl-a concentration (especially 2 band algorithm (2BDA), the Surface Algal Bloom Index (SABI) and 3 band algorithm (3BDA)) even though blue and green bands were useful to classify UAV images into two chl-a ranges. The results show a moderately good agreement among the three sensors at different spatial resolutions (10 m., 30 m. and 8 cm.), indicating a high potential for the development of a multi-platform and multi-sensor approach for the eutrophication monitoring of small reservoirs

Rand Flora
Vicariance
The Rand Flora is a well-known floristic pattern in which unrelated plant lineages
show similar disjunct distributions in the continental margins of Africa and adjacent
islands—Macaronesia-northwest Africa, Horn of Africa-Southern Arabia, Eastern Africa,
and Southern Africa. These lineages are now separated by environmental barriers such
as the arid regions of the Sahara and Kalahari Deserts or the tropical lowlands of Central
Africa. Alternative explanations for the Rand Flora pattern range from vicariance and
climate-driven extinction of a widespread pan-African flora to independent dispersal
events and speciation in situ. To provide a temporal framework for this pattern, we used
published data from nuclear and chloroplast DNA to estimate the age of disjunction of
17 lineages that span 12 families and nine orders of angiosperms. We further used these
estimates to infer diversification rates for Rand Flora disjunct clades in relation to their
higher-level encompassing lineages. Our results indicate that most disjunctions fall within
the Miocene and Pliocene periods, coinciding with the onset of a major aridification trend,
still ongoing, in Africa. Age of disjunctions seemed to be related to the climatic affinities of
each Rand Flora lineage, with sub-humid taxa dated earlier (e.g., Sideroxylon) and those
with more xeric affinities (e.g., Campylanthus) diverging later. We did not find support
for significant decreases in diversification rates in most groups, with the exception of
older subtropical lineages (e.g., Sideroxylon, Hypericum, or Canarina), but some lineages
(e.g., Cicer, Campylanthus) showed a long temporal gap between stem and crown
ages, suggestive of extinction. In all, the Rand Flora pattern seems to fit the definition of
biogeographic pseudocongruence, with the pattern arising at different times in response
to the increasing aridity of the African continent, with interspersed periods of humidity
allowing range expansions.

Drought is one of the key natural hazards impacting net primary production and tree growth in forest ecosystems. Nonetheless, tree species show different responses to drought events, which make it difficult to adopt fixed tools for monitoring drought impacts under contrasting environmental and climatic conditions. In this study, we assess the response of forest growth and a satellite proxy of the net primary production (NPP) to drought in peninsular Spain and the Balearic Islands, a region characterized by complex climatological, topographical, and environmental characteristics. Herein, we employed three different indicators based on in situ measurements and satellite image-derived vegetation information (i.e., tree-ring width, maximum annual greenness, and an indicator of NPP). We used seven different climate drought indices to assess drought impacts on the tree variables analyzed. The selected drought indices include four versions of the Palmer Drought Severity Index (PDSI, Palmer Hydrological Drought Index (PHDI), Z-index, and Palmer Modified Drought Index (PMDI)) and three multi-scalar indices (Standardized Precipitation Evapotranspiration Index (SPEI), Standardized Precipitation Index (SPI), and Standardized Precipitation Drought Index (SPDI)). Our results suggest that—irrespective of drought index and tree species—tree-ring width shows a stronger response to interannual variability of drought, compared to the greenness and the NPP. In comparison to other drought indices (e.g., PDSI), and our results demonstrate that multi-scalar drought indices (e.g., SPI, SPEI) are more advantageous in monitoring drought impacts on tree-ring growth, maximum greenness, and NPP. This finding suggests that multi-scalar indices are more appropriate for monitoring and modelling forest drought in peninsular Spain and the Balearic Islands

Knowledge about the fungal spores most abundant in the atmosphere of a vineyard is of great use since it allows development of prediction models of the spore concentration, and therefore application of phytosanitary treatments only when high levels of
fungal propaguls are detected. In this study the concentration of phytopathogenic spores
is related with the different phenological stages of the vineyard, and a prediction model
developed for each fungal type using meteorological, phenological and spore concentrations variables. The study was carried out in a vineyard of the Ribeiro district during
the year 2007. For the aerobiological study a volumetric Hirst type trap was used, while
phenological observations were carried out on 20 plants of the three varieties monitored
(Treixadura, Godello and Loureira) following the phenological scale standardized by
the BBCH. Botrytis reached the highest annual total value with 16,145 spores, followed
by Plasmopara with 747 spores and Uncinula with 578 spores. In order to forecast the
concentration of the phytopathogenic fungal spores, equations of lineal regression were
elaborated including as estimators, variables with high correlation coefficient. For Botrytis the regression equation explained 42.4% of the variability of spore concentration,
26.1% for Uncinula and 24.7% for Plasmopara

Systematics
Cryptic diversity is common among marine macroalgae, with molecular tools leading to the discovery of many new species. To assign names to these morphologically similar species, the type and synonyms have to be examined, and if appropriate, new species must be described. The turf-forming red alga Polysiphonia scopulorum was originally described from Rottnest Island, Australia, and subsequently widely reported in tropical and temperate coasts based on morphological identifications. A recent study of molecular species delineation revealed a complex of 12 species in Australia, South Africa, and Europe. These species are placed in a taxonomically unresolved lineage of the tribe Polysiphonieae. The aim of this study was to resolve the genus- and species-level taxonomy of this complex and related species using molecular and morphological information. Three morphologically indistinguishable species of the complex were found at the type locality of P. scopulorum, preventing a straightforward assignment of the name to any of the molecular lineages. Therefore, we propose a molecularly characterized epitype. Polysiphonia caespitosa is reinstated for the only species found in its type locality in South Africa. We describe seven new species. Only one species of the complex can be morphologically recognized, with the other eight species indistinguishable based on morphometric analysis. The studied complex, together with another seven species currently placed in Polysiphonia and two Bryocladia species, formed a clade distinct from Polysiphonia sensu stricto. Based on observations of Bryocladia cervicornis (the generitype), we describe our seven new species in the genus Bryocladia and transfer another nine species from Polysiphonia to Bryocladia.

Flower color variation
Local adaptation
Pollinator preferences

Gentiana lutea
Background. The adaptive maintenance of flower color variation is frequently at-tributed to pollinators partly because they preferentially visit certain flower phenotypes.We tested whetherGentiana lutea—which shows a flower color variation (from orangeto yellow) in the Cantabrian Mountains range (north of Spain)—is locally adapted tothe pollinator community.Methods. We transplanted orange-flowering individuals to a population with yellow-flowering individuals and vice versa, in order to assess whether there is a pollinationadvantage in the local morph by comparing its visitation rate with the foreign morph.Results. Our reciprocal transplant experiment did not show clear local morphadvantage in overall visitation rate: local orange flowers received more visits thanforeign yellow flowers in the orange population, while both local and foreign flowersreceived the same visits in the yellow population; thus, there is no evidence of localadaptation inGentiana luteato the pollinator assemblage. However, some floral visitorgroups (such asBombus pratorum,B. soroensis ancaricusandB. lapidarius decipiens)consistently preferred the local morph to the foreign morph whereas others (such asBombus terrestris) consistently preferred the foreign morph.Discussion. We concluded that there is no evidence of local adaptation to the pollinatorcommunity in each of the twoG. luteapopulations studied. The consequences forlocal adaptation to pollinator onG. luteaflower color would depend on the variationalong the Cantabrian Mountains range in morph frequency and pollinator community composition.

Many endangered plants such as Eryngium viviparum (Apiaceae) present a poor germination rate. This fact could be due to intrinsic and extrinsic seed variability influencing germination and dormancy of seeds. The objective of this study is to better understand the physiological mechanism of seed latency and, through artificial intelligence models, to determine the factors that stimulate germination rates of E. viviparum seeds. This description could be essential to prevent the disappearance of endangered plants. Germination in vitro was carried out under different dormancy breaking and incubation procedures. Percentages of germination, viability and E:S ratio were calculated and seeds were dissected at the end of each assay to describe embryo development. The database obtained was modeled using neurofuzzy logic technology. We have found that the most of Eryngium seeds (62.6%) were non-viable seeds (fully empty or without embryos). Excluding those, we have established the germination conditions to break seed dormancy that allow obtaining a real germination rate of 100%. Advantageously, the best conditions pointed out by neurofuzzy logic model for embryo growth were the combination of 1 mg L−1 GA3 (Gibberellic Acid) and high incubation temperature and for germination the combination of long incubation and short warm stratification periods. Our results suggest that E. viviparum seeds present morphophysiological dormancy, which reduce the rate of germination. The knowledge provided by the neurofuzzy logic model makes possible not just break the physiological component of dormancy, but stimulate the embryo development increasing the rate of germination. Undoubtedly, the strategy developed in this work can be useful to recover other endangered plants by improving their germination rate and uniformity favoring their ex vitro conservation

Northern Portugal
The northern Portuguese coast is a biogeographic transition zone where many macroalgal species have their distribution limits; it is thus a particularly interesting region for investigating species distribution shifts. An updated and complete list of species for this region is not available in spite of its baseline importance for comparative studies with past and present data. Based on new records, literature references, and herbarium data, we provide an updated checklist of the benthic marine algae of the northern Portuguese coast. This checklist includes 346 species: 26 Cyanobacteria, 200 Rhodophyta, 70 Ochrophyta, and 50 Chlorophyta. From these, 21 species are new records for the Portuguese coast (Lyngbya aestuarii, Lyngbya semiplena, Microcoleus acutirostris, Myxosarcina gloeocapsoides, Aiolocolax pulchella, Antithamnion densum, Antithamnion villosum, Antithamnionella spirographidis, Dasya sessilis, Furcellaria lumbricalis, Neosiphonia harveyi, Porphyrostromium boryanum, Chorda filum, Dictyopteris ambigua, Sphacelaria rigidula, Undaria pinnatifida, Vaucheria coronata, Vaucheria velutina, Ulothrix implexa, Ulva scandinavica, and Umbraulva olivascens) and 33 were recorded for the first time in the north of Portugal. Alien species have increased in number and extended their distribution range over the last 10 years in the study area. Distribution shifts of northern cold water species with southern distribution limit in the north of Portugal were not consistent among species.
