Speciation [PDF]

open access: yesCold Spring Harbor Perspectives in Biology
What drives the emergence of new species has fascinated biologists since Darwin. Reproductive barriers to gene flow are a key step in the formation of species, and recent advances have shed new light on how these are established. Genetic, genomic, and comparative techniques, together with improved theoretical frameworks, are increasing our ...

Speciation in Freshwater Fishes [PDF]

open access: yesAnnual 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 ...

SPECIATION

TAXON, 1969
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

Theory and speciation

Trends in Ecology & Evolution, 2001
The study of speciation has become one of the most active areas of evolutionary biology, and substantial progress has been made in documenting and understanding phenomena ranging from sympatric speciation and reinforcement to the evolutionary genetics of postzygotic isolation.

Speciation in fungi

Fungal Genetics and Biology, 2008
In this review on fungal speciation, we first contrast the issues of species definition and species criteria and show that by distinguishing the two concepts the approaches to studying the speciation can be clarified. We then review recent developments in the understanding of modes of speciation in fungi.
