Is diversification rate related to climatic niche width?

Carola Gómez-Rodríguez, Andrés Baselga and John J. Wiens. Global Ecology and Biogeography. Article first published online: 10 OCT 2014. Our results identify climatic niche width, and especially the relationship between family and species-level niche widths, as a major correlate of diversification rates among amphibian families. These results suggest that climatic niche divergence among species within clades can be important in explaining large-scale diversity patterns, possibly even more so than a clade’s geographic area or whether it is primarily temperate or tropical.
