13 p, 620.0 KB Urbanisation and the loss of phylogenetic diversity in birds / Sol, Daniel (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Bartomeus, Ignasi (Consejo Superior de Investigaciones Científicas (Espanya)) ; González-Lagos, César (Pontificia Universidad Católica de Chile) ; Pavoine, Sandrine (Université de Paris IV: Paris-Sorbonne. Centre d'Ecologie et des Sciences de la Conservation)
Despite the recognised conservation value of phylogenetic diversity, little is known about how it is affected by the urbanisation process. Combining a complete avian phylogeny with surveys along urbanisation gradients from five continents, we show that highly urbanised environments supported on average 450 million fewer years of evolutionary history than the surrounding natural environments.

13 p, 1.9 MB Edge influence on diversity of orchids in Andean cloud forests / Parra Sánchez, Edicson (Universidad Nacional de Colombia) ; Armenteras, Dolors (Universidad Nacional de Colombia. Departamento de Biología) ; Retana Alumbreros, Javier (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Cloud forests harbor high levels of orchid diversity. However, due to the high fragmentation of these forests in the Andes, combined with the pressure for new agricultural land, orchid diversity is highly threatened. [...]

9 p, 464.7 KB Unexpected biodiversity loss under global warming in the neotropical Guayana Highlands: a preliminary appraisal / Rull, Valentí (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Vegas Vilarrubia, Teresa (Universitat de Barcelona. Departament d'Ecologia.)
The fully vegetated summits of the table mountains that form the Guayana Highlands (GH), in northern South America, hold amazing biodiversity and endemism levels, and unique vegetation types. In spite of their present-day healthy appearance, their biota is seriously threatened of habitat loss by upward displacement, because of the projected warming for the end of this century. [...]

Una de las posibles consecuencias del calentamiento global es la extinción de especies de alta montaña por migración ascendente de las condiciones ambientales y pérdida de hábitat, fenómeno que, por el momento, ha sido considerado únicamente en montañas templadas y boreales. [...]
Among the potential consequences of the projected global warming on high-mountain environments is biodiversity loss by upward migration of environmental conditions and the consequent habitat vanishing for upland species. [...]
