The origin, distribution, and function of biological diversity are fundamental themes of
ecology and evolutionary biology. Research on birds has played a major role in the history …

The evolution of predominant self‐fertilisation frequently coincides with the evolution of a
collection of phenotypes that comprise the 'selfing syndrome', in both plants and animals …

Adaptive radiation plays a fundamental role in our understanding of the evolutionary
process. However, the concept has provoked strong and differing opinions concerning its …

After decades of debate, biologists today largely agree that most speciation events require
an allopatric phase (that is, geographic separation), but the role of adaptive ecological …

The “multispecies” coalescent (MSC) model that underlies many genomic species-
delimitation approaches is problematic because it does not distinguish between genetic …

Studies on the distribution and evolution of organisms on oceanic islands have advanced
towards a dynamic perspective, where terrestrial endemicity results from island …

Recent evidence has questioned whether the Latitudinal Diversity Gradient (LDG), whereby
species richness increases towards the Equator, results in higher rates of speciation in the …

Topographic change shapes the evolution of biodiversity by influencing both habitat
connectivity and habitat diversity as well as abiotic factors like climate. However, its role in …

An implicit assumption of speciation biology is that population differentiation is an important
stage of evolutionary diversification, but its significance as a rate-limiting control on …

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 …
