Species richness increases with energy availability, yet there is little consensus as to the
exact processes driving this species–energy relationship. The most straightforward …

Recent studies have generated an explosion of phylogenetic and biogeographic data and
have provided new tools to investigate the processes driving large-scale gradients in …

Genomic data are rapidly resolving the tree of living species calibrated to time, the timetree
of life, which will provide a framework for research in diverse fields of science. Previous …

Adaptive radiation plays a fundamental role in our understanding of the evolutionary
process. However, the concept has provoked strong and differing opinions concerning its …

Global patterns of biodiversity are influenced by spatial and environmental variations in the
rate at which new species form. We relate variations in speciation rates to six key patterns of …

The incipient sixth mass extinction that started in the Late Pleistocene has already erased
over 300 mammal species and, with them, more than 2.5 billion y of unique evolutionary …

Species richness varies widely across extant clades, but the causes of this variation remain
poorly understood. We investigate the role of diversification rate heterogeneity in shaping …

Using the most comprehensive fish occurrence database, we evaluated the importance of
ecological and historical drivers in diversity patterns of subdrainage basins across the …

Speciation generally involves a three-step process—range expansion, range fragmentation
and the development of reproductive isolation between spatially separated populations …

A regional species pool comprises all species available to colonize a focal site. The roots of
the concept are imbedded in island biogeography theory, supply-side ecology, and early …
