摘要
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.
