High proportion of smaller ranged hummingbird species coincides with ecological...
Sonne, Jesper; Martín González, Ana M.; Maruyama, Pietro Kiyoshi; Sandel, Brody S.; Vizentin-Bugoni, Jeferson; Schleuning, Matthias; Abrahamczyk, StefanEcological communities that experience stable climate conditions have been speculated to preserve more specialized interspecific associations and have higher proportions of smaller ranged species (SRS). Thus, areas with disproportionally large numbers of SRS are expected to coincide geographically with a high degree of community-level ecological specialization, but this suggestion remains poorly supported with ...
Climate change threatens European conservation areas
Araújo, Miguel B.; Alagador, Diogo; Cabeza, Mar; Nogués-Bravo, David; Thuiller, WilfriedEurope has the world’s most extensive network of conservation areas. Conservation areas are selected without taking into account the effects of climate change. How effectively would such areas conserve biodiversity under climate change? We assess the effectiveness of protected areas and the Natura 2000 network in conserving a large proportion of European plant and terrestrial vertebrate species under climate ch...
Measurements of area and the (island) species-area relationship: new directions...
Triantis, Kostas A.; Nogués-Bravo, David; Hortal, Joaquín; Borges, Paulo A. V.; Adsersen, Henning; Fernández-Palacios, José María; Araújo, Miguel B.The species-area relationship is one of the strongest empirical generalizations in geographical ecology, yet controversy persists about some important questions concerning its causality and application. Here, using more accurate measures of island surface size for five different island systems, we show that increasing the accuracy of the estimation of area has negligible impact on the fit and form of the specie...
