Dataset and R scripts from "Phyloregions in American mammals: Contrasting. Biogeographical Patterns with the Evolutionary Histories of Lineage". Journal of Biogeography

Abstract

This database was used to compare mammal phylogenetic regionalization with previous biogeographical maps obtained from the distributional overlap of endemic taxa, considering evolutionary affinities and phylogenetic uniqueness. To test whether there is correspondence between areas of endemism at different spatial scales and phyloregions, driven by unique species or phylogenetic lineages. The distributional and phylogenetic data on 1,782 terrestrial mammal species of the Americas were used to identify spatial patterns in phylogenetic turnover (pβsim), which led to significant clustering of grid-cells (phyloregions) to be compared with traditional biogeographical units. Evolutionary Correspondence Analysis (evoCA) was applied to reveal significant evolutionary divergences among phyloregions, driven by unique species or phylogenetic lineages.
