Climate changes during the late Pleistocene influenced the demography and distribution of species in Patagonia. During the last glacial maximum (LGM), ice sheets covered a great extent of the temperate rainforest in the western Patagonian Andes. The

Spatial segregation of the endemic versus non-endemic hummingbird on Robinson Crusoe Island, Chile: the effect of competitor abundance but not resources or habitat

Autor: Jeferson Vizentin-Bugoni, Erin Hagen, Peter Hodum, Jesper Sonne, Juliana Cordeiro

Publikováno v: Journal of Ornithology. 158:793-798

Competitive pressure from invasive species tends to have a particularly strong impact on remote islands, and knowledge of such phenomena can be crucial to the conservation of endemic biodiversity. Of the two hummingbird species inhabiting Robinson Cr

Publikováno v: Population Ecology. 57:143-149

It is a long-standing question how tsunamis can influence wild populations of animals and plants. Here, we assessed short-term changes in the population of the criti- cally endangered Juan Fernandez Firecrown (Sephanoides fernandensis) by using abund

Habitat selection and population trends in terrestrial bird species of Robinson Crusoe Island: habitat generalists versus forest specialists

Autor: Uwe Römer, Pablo M. Vergara, Ingo J. Hahn

Publikováno v: Biodiversity and Conservation. 20:2797-2813

Habitat loss and degradation on oceanic islands are key processes leading to population decline of endemic birds and facilitating the establishment of invasive bird species. In this study, carried out in the Robinson Crusoe Island, we assessed densit
