Contrasting mechanisms driving the northward expansion of African raptors in Europe
Journal of Zoology, EarlyView.Recent climate warming and landscape changes are enabling African raptors to reach Europe through contrasting mechanisms. Using species distribution models, we show that the Atlas Long‐legged Buzzard expands northward following climatic suitability, whereas African vultures reach Europe despite low climatic favourability through socially mediated ...

Journal of Zoology, EarlyView.In this study we tested the effects of insularity on amphibian colouration using the fire salamander as a model system. Although increased melanism was not a consistent pattern across all islands, salamanders from one island exhibited higher proportions of black pigmentation than mainland populations, while insular populations overall showed reduced ...

Elevation shapes alpine snow algal blooms and their influence on albedo reduction
New Phytologist, EarlyView.Graphical summary of elevational trends in Sanguina‐dominated snow algal blooms. Increasing elevation was associated with larger cells, lower Chla content per cell, higher astaxanthin ratios, lower snow water content, and reduced cell‐normalized albedo, whereas algal cell density showed no consistent elevational trend.

New Phytologist, EarlyView.Community‐level fitted relationship between spatial association Lij and trait dissimilarity (tDij) at the fine spatial scale (r = 40 mm; where r represents the radius around individuals of the focal species). Summary Predicting coexistence in species‐rich plant communities requires understanding the role of functional traits in species interactions and

Plant Biology, EarlyView.Expression of genetic differences depends on the experimental environment as seen in flowering time differences between ancestors and descendants that emerge in climate chambers but not in greenhouse or garden conditions. Abstract Common‐environment experiments are important to study genetically based phenotypic variation within and among plant ...

, 1975 El presente trabajo pretende ser un ensayo sobre la burocracia en los países en vías de desarrollo. Ensayo que pone énfasis en los aspectos fundamentales de la misma: en la necesidad organizativa y en las contradicciones que genera la aplicación de un modelo “ideal”, basados en los análisis de Weber.
