Flavia Montaño-Centellas with co-authors Bette Loiselle and Morgan Tingley have published a new paper in Ecography that examines the role of abiotic filtering and biological interactions in explaining bird community assemblages along an extensive elevational gradient in Bolivia.  This paper results from Flavia’s PhD research support the hypothesis of abiotic filtering as a primary driver that shapes bird assemblages, but provides evidence that locally resource availability also plays a role.  The research advances our understanding of community assembly and applies a novel analytical technique that accounts for imperfect detection, thus reducing potential biases associated with sampling diverse tropical communities.  You can learn more about this study here.
