Western North American Naturalist (August 2004) 64: 396-402.
Discusses the historical biogeography of the Woodchuck (Marmota monax bunkeri) in Nebraska and northern Kansas.
Jones et al. described the western limit of Marmota monax in the United States as the eastern edge of the northern Great Plains in Oklahoma, Kansas, Nebraska, and the Dakotas. Mengel introduced the idea of the Great Plains grasslands as a barrier to contact between birds of eastern and western North American forests. In his studies of bird biogeography on the Platte River, Knopf reported that this barrier has eroded with development of riparian forests along river courses of the Great Plains. This concept can also he applied to mammalian faunal distributions.
