Divergence with gene flow is well documented and reveals the influence of ecological
adaptation on speciation. Yet, it remains intuitive that gene exchange inhibits speciation in …

The formation of independent evolutionary lineages involves neutral and selective factors,
and understanding their relative roles in population divergence is a fundamental goal of …

Dry forest bird communities in South America are often fragmented by intervening mountains
and rainforests, generating high local endemism. The historical assembly of dry forest …

According to models of ecological speciation, adaptation to adjacent, contrasting habitat
types can lead to population divergence given strong enough environment‐driven selection …

During the process of ecological speciation, reproductive isolation results from divergent
natural selection and leads to a positive correlation between genetic divergence and …

Discerning the relative roles of adaptive and nonadaptive processes in generating
differences among populations and species, as well as how these processes interact, is a …

Understanding the factors that govern variation in genetic structure across species is key to
the study of speciation and population genetics. Genetic structure has been linked to several …

Speciation is a complex process, in part because it can be caused by a multitude of different
mechanisms. One aspect of speciation that has received much attention lately is the …

Phenotypic differentiation plays an important role in the formation and maintenance of
reproductive barriers. In some cases, variation in a few key aspects of phenotype can …

Do related populations that are separated by barriers predictably evolve differences from
one another over time, or is such divergence idiosyncratic and unpredictable? We test these …
