Speciation, the evolution of reproductive isolation among populations, is continuous,
complex, and involves multiple, interacting barriers. Until it is complete, the effects of this …

The metaphor of 'genomic islands of speciation'was first used to describe heterogeneous
differentiation among loci between the genomes of closely related species. The biological …

The origin of biological diversity, via the formation of new species, can be inextricably linked
to adaptation to the ecological environment. Specifically, ecological processes are central to …

Speciation is a continuous process during which genetic changes gradually accumulate in
the genomes of diverging species. Recent studies have documented highly heterogeneous …

Understanding the effects of landscape heterogeneity on spatial genetic variation is a
primary goal of landscape genetics. Ecological and geographic variables can contribute to …

Levels of genetic differentiation between populations can be highly variable across the
genome, with divergent selection contributing to such heterogeneous genomic divergence …

Species are commonly thought to be evolutionarily independent in a way that populations
within a species are not. In recent years, studies that seek to identify evolutionarily …

The large body of theory on speciation with gene flow has brought to light fundamental
differences in the effects of two types of mating rules on speciation: preference/trait rules, in …

Species‐level taxonomy derives from empirical sources (data and techniques) that assess
the existence of spatiotemporal evolutionary lineages via various species “concepts.” These …

Ecological speciation is the process by which reproductively isolated populations emerge as
a consequence of divergent natural or ecologically-mediated sexual selection. Most …
