Molecular phylogeny of North American long-eared bats (Vespertilionidae: Corynorhinus); inter- and intraspecific relationships inferred from mitochondrial and nuclear DNA sequences.
Mol Phylogenet Evol. 2005 Dec; 37(3):762-75.MP

Abstract

The taxonomy of the North American big-eared bats, genus Corynorhinus, was revised by Handley [Handley, C.O., 1959. A revision of the American bats of the genera Euderma and Plecotus. Proc. U.S. Nat. Mus. 110, 95-246] using a morphological systematics approach. Handley employed 17 morphological characters and identified only four characters that reliably differentiated the three species he recognized, C. townsendii, C. rafinesquii, and C. mexicanus. All three species have been shown to lead relatively sedentary lives and have a wing morphology that limits long-distance dispersal. Further, populations of two species, C. townsendii and C. rafinesquii, are considered to be declining. Handley [Handley, C.O., 1959. A revision of the American bats of the genera Euderma and Plecotus. Proc. U.S. Nat. Mus. 110, 95-246] recognized five subspecies of C. townsendii (C. t. australis, C. t. ingens, C. t. pallescens, C. t. townsendii, and C. t. virginianus) and two of C. rafinesquii (C. r. rafinesquii and C. r. macrotis). Two C. townsendii subspecies, C. t. ingens and C. t. virginianus, are listed as endangered under the Endangered Species Act. These facts and the lack of a thorough molecular systematic examination of this genus were the impetus for this study. Using mitochondrial and nuclear intron DNA sequences, a molecular phylogeny was inferred. The combined DNA phylogeny supports Handley's [Handley, C.O., 1959. A revision of the American bats of the genera Euderma and Plecotus. Proc. U. S. Nat. Mus. 110, 95-246] designation of three species. Further the endangered subspecies, C. t. ingens and C. t. virginianus are corroborated, as were the monophyly of the other subspecies. However, the geographical ranges of two of these subspecies, C. t. pallescens and C. t. townsendii, are revised based on biogeographic distributions as understood from our results. Estimates of timing of divergences indicate that the three species, C. townsendii, C. rafinesquii, and C. mexicanus may have diverged before Pleistocene climatic oscillations began, and therefore their cladogenesis was not the result of those processes. However, subspecific divergences within C. townsendii appear to have occurred during and been driven largely by the climatic processes of the Pleistocene Epoch. We propose new hypotheses of dispersal scenarios that may have led to the current biogeography of these lineages.
