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, ... -
Use of phenological and pollen-production data for interpreting atmospheric birch pollen curves
(Institute of Rural Health (Lublin), 2007)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 ... -
Incidence of fungals in a vineyard of the denomination of origin ribeiro (Ourense - north-western Spain)
(Institute of Rural Health (Lublin), 2009)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 ... -
Mass mortality of seabirds in the aftermath of the Prestige oil spill
(Wiley, 2011)In the winter of 2002–03 the Prestige tanker spilled 60,000 tons of oil over the northern half ofthe Iberian Coastal Large Marine Ecosystem (northern Portugal to France). Most (c. 85%) of the 22,981 oiledseabirds reported ... -
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 ... -
From Land Cover to Land Use: A Methodology to Assess Land Use from Remote Sensing Data
(MDPI, 2012)The “land use” concept has evolved during recent decades and it is now considered as the socioeconomic function of land. Land use representation and land use change assessment through remote sensing still remains one of ... -
Selective pressure along a latitudinal gradient affects subindividual variation in plants
(PLOS, 2013)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 ... -
Alpine Ecology in the Iberian Peninsula: What Do We Know, and What Do We Need to Learn?
(International Mountain Society, 2013)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 ... -
Symphytosociological nomenclature: new proposal
(Universidad Complutense de Madrid, 2014)A new nomenclatural formula for vegetation series is proposed that is more closely in line with the commonly-usedf orms of phytosociological nomenclature. The concept of facies associated to the appearance of a vegetation ... -
Is there a hybridization barrier between Gentiana lutea color morphs?
(PeerJ Inc., 2015)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 ... -
Selective pressures explain differences in flower color among Gentiana lutea Populations
(PLOS, 2015)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 ... -
Living on the edge: timing of Rand Flora disjunctions congruent with ongoing aridification in Africa
(Frontiers Media, 2015)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 ... -
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 ... -
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 ... -
High-Resolution Airborne UAV Imagery to Assess Olive Tree Crown Parameters Using 3D Photo Reconstruction: Application in Breeding Trials
(MDPI, 2015)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 ... -
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, ... -
