Main image for New paper about extinctions in Amazonian bird communities

Tom Bregman (Biodiversity Group alumnus now based at the Global Canopy Programme) published a paper in Ecology titled ‘Species interactions regulate the collapse of biodiversity and ecosystem function in tropical forest fragments‘. His analysis of Amazonian bird communities revealed that extinctions were not only driven by fragment size and isolation, but also by interactions among species, probably because of increased competition between closely related species as fragment size (and thus resource pool) declines.
