Variation in the rate of species diversification underlies many large-scale patterns in the
organization of biological diversity. Here, I explore the phenomenon of diversity-dependent …

Rapid adaptive radiation poses two distinct questions apart from speciation and adaptation:
What happens after one speciation event and how do some lineages continue speciating …

Accurate taxonomy is central to the study of biological diversity, as it provides the needed
evolutionary framework for taxon sampling and interpreting results. While the number of …

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 …

A key measure of humanity's global impact is by how much it has increased species
extinction rates. Familiar statements are that these are 100–1000 times pre‐human or …

A number of methods have been developed to infer differential rates of species
diversification through time and among clades using time-calibrated phylogenetic trees …

Speciation events often occur in rapid bursts of diversification, but the ecological and genetic
factors that promote these radiations are still much debated. Using whole transcriptomes …

Several evolutionary theories predict that rates of morphological change should be
positively associated with the rate at which new species arise. For example, the theory of …

Our growing understanding of the plant tree of life provides a novel opportunity to uncover
the major drivers of angiosperm diversity. Using a time‐calibrated phylogeny, we …

Summary Oaks (Quercus, Fagaceae) are the dominant tree genus of North America in
species number and biomass, and Mexico is a global center of oak diversity. Understanding …
