Data from: A continent-scale test of multiple hypotheses on the abundances of Neotropical birds

David W. Kikuchi, Gustavo H. Kattan & Kimberly C. Navarro Velez
Explaining variation in the abundance of species remains a challenge in ecology. We sought to explain variation in abundance of Neotropical forest birds using a dataset of population densities of 596 species. We tested a priori hypotheses for the roles of species traits, environmental factors, and species interactions. Specifically, we focused on four factors: 1) body mass (trait); 2) habitat type (environmental factor), 3) net primary productivity (NPP; environmental factor); and 4) species richness of...
