Crecimiento estacional y caída de acículas en Pinus uncinata Ram. y Pinus sylvestris L.
En este trabajo se estudia la formación mensual del anillo del tronco, la caída de acículas y la elongación de las ramas en poblaciones de Pinus sylvestris L. y Pinus uncinata Ram. en el Pirineo Central Español durante ...
Schizophrenia polygenic risk score in psychosis proneness
Schizophrenia (SZ) is a complex disorder with a highly polygenic inheritance. It can be conceived as the extreme expression of a continuum of traits that are present in the general population often broadly referred to as ...
Examining the temporal effects of wildfires on forest birds: Should I stay or should I go?
In flammable ecosystems, forest dynamics are affected by fire suppression, climate change and changes in land use that cause the frequency and intensity of fires to diverge from natural fire regimes. Although afforestation ...
Estudis de les restes humanes del Neolític Antic de la comarca del Montsià (Tarragona)
[ESP]Se trata del estudio de los restos óseos y dentarios procedentes de once yacimientos neolIticos de Ia comarca del Montsià. Se ha realizado un trabajo comparativo de la dentición, y el estudio de la dieta mediante el ...
Unreported catches, impact of whaling and current status of blue whales in the South European Atlantic Shelf.
The North Atlantic blue whale was depleted by modern whaling and it is still considered to be highly endangered. Despite its protection in 1954, catches continued in the South European Atlantic Shelf (SEAS) region and ...
Water stress protection by the arbuscular mycorrhizal fungus<em> Rhizoglomus irregulare</em> involves physiological and hormonal responses in an organ-specific manner
Arbuscular mycorrhizal fungi may alleviate water stress in plants. Although several protection mechanisms have already been described, little information is available on how these fungi influence the hormonal response to ...
Responses of microbial activity in hyporheic pore water to biogeochemical changes in a drying headwater stream
Microbial heterotrophic activity is a major driver of nutrient and organic matter processing in the hyporheic zone of headwater streams. Additionally, the hyporheic zone might provide refuge for microbes when surface flow ...
Notas sobre la vegetacion del valle de Ribes
El valle de Ribes, situado en el extremo interior de los Pirineos orientales, representa una zona de transición entre las comarcas lluviosas del nordeste de Cataluña y el país relativamente seco y continental que se extiende ...
An evaluation of whale skin differences and its suitability as a tissue for stable isotope analysis
Stable isotope analysis of whale skin has been recurrently used to assess diet and movement patterns. Such studies rely on the untested assumption that the stable isotope ratios in the small skin biopsies analysed are ...
Sea slug night fever: 39 new records of elusive heterobranchs in the western Mediterranean (Mollusca: Gastropoda)
Citizen (or community) science has provided copious and valuable information about charismatic marine taxa such as heterobranch gas- tropods, thus contributing enormously to the known geographic dis- tribution of many sea ...
Spatial variability and temporal trends in water-use efficiency of European forests
The increasing carbon dioxide (CO2) concentration in the atmosphere in combination with climatic changes throughout the last century are likely to have had a profound effect on the physiology of trees: altering the carbon ...
Bacterioplankton seasonality in deep high-mountain lakes
Due to global warming, shorter ice cover duration might drastically affect the ecology of lakes currently undergoing seasonal surface freezing. Highmountain lakes show snow-rich ice covers that determine contrasting ...
Biomonitoreo de la calidad del agua en los ríos ibéricos: lecciones aprendidas.
Los autores resumen en un decálogo la experiencia de más de 30 años de estudio de los ríos españoles con dos focos principales: el uso de macroinvertebrados para la obtención de la calidad biológica y el diseño de sistemas ...
Synergus brevis (Weld, 1962), una nova sinonímia de S. mexicanus Gillette, 1896 (Hym., Cynipidae: Synergini)
Espècie originalment descrita en el gènere Saphonecrus Dalla Torre & Kieffer, 1910, atès que tenia la cel·la radial oberta (Weld, 1926), ha estat recentment transferida al gènere Synergus Hartig, 1840 per Schwéger et al. (2015).
Towards understanding the organisation of metacommunities in highly dynamic ecological systems.
Community ecology recognises today that local biological communities are not only affected by local biotic interactions and abiotic environmental conditions, but also by regional processes (e.g. dispersal). While much is ...
The whereabouts of an ancient wonderer: Global phylogeography of the solitary ascidian Styela plicata
Genetic tools have greatly aided in tracing the sources and colonization history of introduced species. However, recurrent introductions and repeated shuffling of populations may have blurred some of the genetic signals ...
Roser Nos. La zoologia al servei de la ciutadania
Roser Nos. Zoology at the service of citizenry. Roser Nos Ronchera (1924-2018) was a good example of a scientist capable of overcoming, with great tenacity, a series of adversities to develop a long and remarkable career. ...
Rareza en la nora pirenaica. Materiales preliminares para una lista roja
Based on the revision of the online digital Atlas of the Pyrenees Flora, we have selected a preliminary list of the rarest plants of the Pyrenean mountain range. The presence of plants in 1-4 squares, including other taxa, ...
Understanding oceanic migrations with intrinsic biogeochemical markers
Migratory marine vertebrates move annually across remote oceanic water masses crossing international borders. Many anthropogenic threats such as overfishing, bycatch, pollution or global warming put millions of marine ...
Leaf orientation as part of the leaf developmental program in the semi-deciduous shrub, Cistus albidus l.: Diurnal, positional, and photoprotective effects during winter
Mediterranean ecosystems harbor a very important part of Earth's biodiversity, and they are a conservation priority due to the effects of global change. Here, we examined the performance of the semi-deciduous shrub Cistus ...
