Historical biogeography of sigmodon ochrognathus in texas usa

Historical biogeography of sigmodon ochrognathus in texas usa

Texas Journal of Science 43(2): 127-132

Re-examination of Holocene and Pleistocene Sigmodon remains from Trans-Pecos Texas provides the first extralimital fossil record for S. ochrognathus, and the second report of fossils of this taxon in the literature. Presence of the species in the Guadalupe and Apache mountains from latest Pleistocene through relatively recent times, along with the recent report of a specimens of a yellow-nosed cotton rat from the Guadalupe Mountains, indicates a variable refugial population yet may survive in the Guadalupes.
