Climate change is creating mismatches between species' current environments and their historical niches. Locations that once had the abiotic and biotic conditions to support the persistence of a species may now be too warm, too dry, or simply too different, to meet their niche requirements. Changes in behaviors, altered phenology, and range shifts are common responses to climate change. Though these responses are often studied...

Aim We investigate geographic patterns across taxonomic, ecological and phylogenetic diversity to test for spatial (in)congruency and identify aggregate diversity hotspots in relationship to present land use and future climate. Simulating extinctions of imperilled species, we demonstrate where losses across diversity dimensions and geography are predicted. Location North America. Time period Present day, future. Major taxa stu...

Past climate change has caused shifts in species distributions and undoubtedly impacted patterns of genetic variation, but the biological processes mediating responses to climate change, and their genetic signatures, are often poorly understood. We test six species‐specific biologically informed hypotheses about such processes in canyon live oak ( Quercus chrysolepis ) from the California Floristic Province. These hypotheses e...

By employing a recently inferred phylogeny and museum occurrence records, we examine the relationship of ecological niche evolution to diversification in the largest family of songbirds, the tanagers (Thraupidae). We test whether differences in species numbers in the major clades of tanagers can be explained by differences in rate of climatic niche evolution. We develop a methodological pipeline to process and filter occurrenc...
