Many of these studies have found evidence of isolation during Pleistocene glacial cycles, and allopatric
divergence is often thought to be the main route to speciation in birds (Mayr 1963, Coyne and Orr 2004).
The most recent taxonomic revision of the Aspidoscelis hyperythra complex (Grismer, 1999) used the operationalism of diagnosable allopatric
populations to elevate five insular populations, recognized as subspecies by Walker and Taylor (1968), to species rank.
Each crater lake can be seen as a "natural experiment" of sympatric and allopatric
All of the species are allopatric
and there is no known geographical overlap, and from the first eophylls to especially mature plants, the species can be separated.
Most of the branchiopod taxa sampled during the study are usually allopatric
Evidence for this ancient relationship includes the association of phylogenetically closely related hantavirus species with phylogenetically closely related allopatric
At the highest clade level (4-1) and most distant past (Templeton 1998), allopatric
fragmentation between the Gulf and Atlantic clades generated the genetically differentiated subspecies existing today.
Introgression as a likely cause of mtDNA paraphyly in two allopatric
skippers (Lepidoptera: Hesperiidae).
2001), despite the fact that many ferns produce bisexual spores capable of travelling long distances, chances of establishing new populations are low; in this way, evidence of historical processes such as allopatric
differentiation may sometimes be hidden by dispersal.
According to phenetic characters observed, as well as the current diversity of the genus Atractus coming from highland environments that seems to respond to a pattern of allopatric
speciation (geographical replacement of species) and the current knowledge concerning most of species in Venezuela (comparative analysis), there are arguments conclusive to justify a description in this taxon based on the single specimen known.
Transmission dynamics and epidemiology of Rhodesian sleeping sickness in allopatric
populations of Glossina pallidipes of Kenya.
Most scientists believe that allopatric
speciation, where different species arise from an ancestral species only after breeding populations have become physically isolated from each other, is the dominant mode of speciation both on land and in the sea.
