Species limits and the evolutionary mechanisms that have shaped diversification of
woodpeckers and allies (Picidae) remain obscure, as inter and intraspecific phylogenetic …

In Colombia, the Andes split into three more or less parallel, north–south oriented mountain
ranges, the West, Central and East Andes. At 6–7 N, the East Andes reach their widest point …

Litle empirical evidence has ever been presented to justify the taxonomic ranking of
Koepcke's Screech Owl Megascops koepckeae. We summarise current knowledge of its …

Sirystes was for a long time treated as a monotypic genus with several subspecies, one of
which was recently proposed for species rank. Vocal differentiation in the genus was studied …

Methods I tape-recorded songs of four individuals of rufipectus at 1,200–1,800 m in the
recently established ProAves Colombia reserve 'El Dorado'on the San Lorenzo ridge in the …

The White-throated Foliage-gleaner Automolus roraimae has been a subject of taxonomic
and nomenclatural debate almost since its description in 1884. Here, we present vocal …

Most studies of species diversity in habitat fragments are conducted either implicitly or
explicitly within the context of the island model of population dynamics, or of species-specific …

Los modelos de distribución de especies–basados en variables ambientales-son una
herramienta analítica para la biogeografía y el estudio del impacto potencial del cambio …

Species distribution modeling is presented as an analytical tool for biogeography and the
study of climate change impact on biodiversity. The maximum entropy principle is described …
