Explaining broad molecular, phenotypic and species biodiversity patterns necessitates a
unifying framework spanning multiple evolutionary scales. Here we argue that although …

Coupling has emerged as a concept to describe the transition from differentiated
populations to newly evolved species through the strengthening of reproductive isolation …

Pioneer naturalists such as Whewell, Lyell, Humboldt, Darwin and Wallace acknowledged
the interactions between ecological and evolutionary forces, as well as the roles of …

Speciation is driven by the evolution of reproductive isolating barriers that reduce, and
ultimately prevent, substantial gene flow between lineages. Despite its central role in …

Over the past century, ecologists have attempted to understand patterns of species diversity
by showing stable coexistence arising from a baseline expectation of competitive exclusion …

Ephemeral resource patches (ERPs)–short lived resources including dung, carrion,
temporary pools, rotting vegetation, decaying wood, and fungi–are found throughout every …

Ecologically mediated selection against hybrids, caused by hybrid phenotypes fitting poorly
into available niches, is typically viewed as distinct from selection caused by epistatic …

Biologists are often stuck between two opposing questions: Why are there so many species
and why are there not more? Although these questions apply to the maintenance of existing …

Hybridization as an evolutionary process has been studied in depth over the past few
decades. Research has focused on its role in shaping reproductive barriers, its adaptive …

It is thought that two species can coexist if they use different resources present in the
environment, yet this assumes that species are completely reproductively isolated. We …
