Our #RacerScholar this week is: Robert A. Martin, Ph. D.

This week’s #RacerScholar is Professor Emeritus of Biological Sciences, Dr. Robert A. Martin. The article, “A preliminary diversity-divergence model for North American arvicolid rodents,” by Dr. Martin, appears in volume 95, issue 3, of the academic journal Palaeobiodiversity and Palaeoenvironments.

Abstract:

North American arvicolid rodent diversity is compared with global arvicolid diversity in a new phylogenetic model incorporating the possibility that the Arvicolidae as presently constituted is polyphyletic. It is likely that many early Pleistocene arhizodont arvicolinins (e.g. Arvicola, Microtus, Victoriamys) evolved from different Mimomys ancestors. North American phylogenetic patterns indicate successive waves of dispersal from Asia, coupled with endemic radiation of the Plophenacomyinae from an ancestral Promimomys, such as P. mimus.
