PhD Project

Unraveling Drivers of Bird Species Distribution in a Central Amazon Forest

Bird species are thought to be good dispersers. Therefore, most studies claim that their distribution is driven by environmental factors rather than by dispersal limitations and barriers. However, in species-rich tropical forests such as the Amazon, birds are notoriously sedentary and present highly reduced dispersal ability, with distributions restricted by large rivers, and territories delimited even by narrow roads. This suggests that dispersal limitation may play an important role on Amazonian bird species’ distribution. With this project we attempt to unravel the relative importance of environmental characteristics and dispersal limitation in (1) structuring populations genetically and (2) creating differences in species composition among sites (beta-diversity).
