Chemical contaminants (eg metals, pesticides, pharmaceuticals) are changing ecosystems
via effects on wildlife. Indeed, recent work explicitly performed under environmentally …

Speciation is a fundamental evolutionary process, the knowledge of which is crucial for
understanding the origins of biodiversity. Genomic approaches are an increasingly …

In recent years, scientists have realized that evolution can occur on timescales much shorter
than the" long lapse of ages" emphasized by Darwin—in fact, evolutionary change is …

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

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 …

Acoustic signals mediate mate choice, resource defense, and species recognition in a broad
range of taxa. It has been proposed, therefore, that divergence in acoustic signals plays a …

Speciation with gene flow is greatly facilitated when traits subject to divergent selection also
contribute to non-random mating. Such traits have been called 'magic traits', which could be …

Phylogenetic niche conservatism (PNC) typically refers to the tendency of closely related
species to be more similar to each other in terms of niche than they are to more distant …

A fundamental challenge to our understanding of biodiversity is to explain why some groups
of species undergo adaptive radiations, diversifying extensively into many and varied …

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 …
