Speciation in Freshwater Fishes
Annual Review of Ecology, Evolution, and Systematics, 2014 The extraordinary species richness of freshwater fishes has attracted much research on mechanisms and modes of speciation. We here review research on speciation in freshwater fishes in light of speciation theory, and place this in a context of broad ...

THE BIOLOGY OF SPECIATION [PDF]
Evolution; International Journal of Organic Evolution, 2010 Since Darwin published the "Origin," great progress has been made in our understanding of speciation mechanisms. The early investigations by Mayr and Dobzhansky linked Darwin's view of speciation by adaptive divergence to the evolution of reproductive isolation, and thus provided a framework for studying the origin of species.

Trends in Ecology & Evolution, 1998
Recent studies on diverse taxa suggest that natural selection caused by shifts in ecology or invasions of novel habitats plays an important role in adaptive divergence and speciation. Exciting new studies integrating approaches from both the field and the laboratory suggest that ecological shifts can result in extremely rapid rates of evolutionary ...

SummaryA discussion of speciation subsumes that we know what a species is, which operationally is true. Populations that are physiologically incapable of gene exchange and are phenotypically distinguishable pose no problem at the species level. When barriers are not absolute or when they are complete but the phenotypic differences are inconspicuous one
