Community phylogeographic patterns reveal how a barrier filters and structures taxa in North American warm deserts

摘要

Aim The study of biogeographic barriers is instrumental in understanding the evolution and distribution of taxa. With the increasing availability of empirical datasets, emergent patterns can be inferred from communities by synthesizing how barriers filter and structure populations across species. We assemble phylogeographic data across a barrier and perform spatially explicit simulations, quantifying spatiotemporal patterns of divergence, the influence of traits on these patterns, and the statistical power needed to differentiate diversification modes.
