Species diversification—the balance between speciation and extinction—is fundamental to
our understanding of how species richness varies in space and time and throughout the …

Motivation Theory describing biodiversity gradients has focused on species richness with
less conceptual synthesis outlining expectations for intraspecific diversity gradients, that is …

Understanding the processes of population divergence and speciation remains a core
question in evolutionary biology. For nearly a hundred years evolutionary geneticists have …

Evaluating the factors that drive patterns of population differentiation in plants is critical for
understanding several biological processes such as local adaptation and incipient …

Dispersal ability is known to influence geographical structuring of genetic variation within
species, with a direct relationship between low vagility and population genetic structure …

Studies of speciation typically investigate the evolution of reproductive isolation between
populations, but several other processes can serve as key steps limiting the formation of …

Rates of species formation vary widely across the tree of life and contribute to massive
disparities in species richness among clades. This variation can emerge from differences in …

Species delimitation is a first step for realizing the extent of biodiversity and is relevant for all
downstream applications in biology. The production of large genome-scale datasets for non …

Genetic structure can be influenced by local adaptation to environmental heterogeneity and
biogeographic barriers, resulting in discrete population clusters. Geographic distance …

Species‐level diversity and the underlying mechanisms that lead to the formation of new
species, that is, speciation, have often been confounded with intraspecific diversity and …
