Bioclimatic mapping as a new method to assess effects of climatic change
(Wiley, 2015)Rigorous mapping of climatic patterns outstands as one of the mayor issues concerningclimatic change. This paper investigates the extent of the bioclimatic approach to develop a rigorouscartographic methodology to express ... -
Catálogo de los líquenes saxícolas (Ascomycota) del área arqueológica de Siega Verde (Salamanca, España)
(Consejo Superior de Investigaciones Científicas (CSIC), 2018-12)Se presentan aquí los resultados parciales de un proyecto de investigación en el que se han estudiado la biodiversidad liquénica y los procesos de biodeterioro en los que están englobados los líquenes de dos yacimientos ... -
Characterisation of Holocene plant macrofossils from North Spanish ombrotrophic mires: vascular plants
(International Mire Conservation GroupInternational Peatland Society, 2016)Methods and criteria that were used to identify plant macrofossils from four ombrotrophic mires in northern Spain are presented. Twelve monocotyledon and ten dicotyledon species were recorded. Some were identified from ... -
Colony Foundation in an Oceanic Seabird
(PLOS, 2016-02-24)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 ... -
Computer-Assisted Recovery of Threatened Plants: Keys for Breaking Seed Dormancy of Eryngium viviparum
(Frontiers Media, 2017)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 ... -
Differences in pollination success between local and foreign flower color phenotypes: a translocation experiment with Gentiana lutea (Gentianaceae)
(PeerJ Inc., 2017)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 ... -
Diversidad fúngica en la atmósfera de La Habana (Cuba) durante tres períodos poco lluviosos
(Universidad Nacional Autónoma de México, 2019)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 ... -
Drought sensitiveness on forest growth in Peninsular Spain and the Balearic Islands
(MDPI, 2018)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 ... -
Effects of thinning intensity on radial growth patterns and temperature sensitivity in Pinus canariensis afforestations on Tenerife Island, Spain
(Springer Verlag, 2015-02-19)The suitability of thinning to prevent forest growth decline from global warming has been 25 scarcely tested in the Macaronesian Canary pine (Pinus canariensis Sweet ex Spreng.). We used tree-ring series from dominant, ... -
Environmental factors affecting the start of pollen season and concentrations of airborne Alnus pollen in two localities of Galicia (NW Spain)
(Institute of Rural Health (Lublin), 2004)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, ... -
Estimating biomass of mixed and uneven-aged forests using spectral data and a hybrid model combining regression trees and linear models
(Italian Society of Silviculture and Forest Ecology (SISEF), 2015)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 ... -
Evaluation of Radiometric and Atmospheric Correction Algorithms for Aboveground Forest Biomass Estimation Using Landsat 5 TM Data
(MDPI, 2016-04-29)Solar radiation is affected by absorption and emission phenomena during its downward trajectory from the Sun to the Earth’s surface and during the upward trajectory detected by satellite sensors. This leads to distortion ... -
Feedbacks between earlywood anatomy and non-structural carbohydrates affect spring phenology and wood production in ring-porous oaks
(Copernicus Publications, 2016-10-05)Non-structural carbohydrates (NSC) play a central role in the construction and maintenance of a tree's vascular system, but feedbacks between the NSC status of trees and wood formation are not fully understood. We aimed ... -
Forecasting ARIMA models for atmospheric vineyard pathogens in Galicia and Northern Portugal: Botrytis cinerea spores
(Institute of Rural Health (Lublin), 2012)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 ... -
