This seasonality gradient spans Neotropical wet forests, savannas, and highly Edited by B-E Van Wyk seasonal drought-prone woody vegetation known as the succulent biome. Ecological phylogenetic structure was investigated using a community phylogenetic approach. We further analyzed bioclimatic and other Keywords: independent variables that potentially explained phylogenetic beta diversity among 466 floristic sites that Leguminosae spanned the savanna and succulent biomes in eastern South America.
