Tests of pleistocene speciation in montane grasshoppers (genus Melanoplus) from the sky islands of western North America.

Evolution; international journal of organic evolution - 1 Aug 2000

Abstract excerpt

There has a been a resurgence of debate on whether the Pleistocene glaciations inhibited speciation. This study tests a model of Pleistocene speciation, estimating the phylogenetic relationships and divergence times of 10 species of montane grasshoppers, genus Melanoplus, using 1300 bp of the mitochondrial gene cytochrome oxidase I (COI). Based on average pairwise distances (corrected for multiple substitutions...
