The ability to reproduce is the key trait that distinguishes living organisms from inorganic
matter, and the strategies used to achieve successful reproduction are almost as diverse as …

Haldane's rule occupies a special place in biology as one of the few 'rules' of speciation,
with empirical support from hundreds of species. And yet, its classic purview is restricted …

Rates of hybridization are predicted to increase due to climate change and human activity
that cause redistribution of species and bring previously isolated populations into contact. At …

Rapidly evolving taxa are excellent models for understanding the mechanisms that give rise
to biodiversity. However, developing an accurate historical framework for comparative …

When gene flow accompanies speciation, recombination can decouple divergently selected
loci and loci conferring reproductive isolation. This barrier to sympatric divergence …

We consider how the genetic architecture underlying locally adaptive traits determines the
strength of a barrier to gene flow in a mainland-island model. Assuming a general life cycle …

Isolation by environment (IBE) is a population genomic pattern that arises when ecological
barriers reduce gene flow between populations. Although current evidence suggests IBE is …

Understanding the genetics of adaptation and speciation is critical for a complete picture of
how biodiversity is generated and maintained. Heterogeneous genomic differentiation …

Biological introductions are unintended “natural experiments” that provide unique insights
into evolutionary processes. Invasive phytophagous insects are of particular interest to …

Haldane's rule—a pattern in which hybrid sterility or inviability is observed in the
heterogametic sex of an interspecific cross—is one of the most widely obeyed rules in …
