| a molecular perspective on the systematics and evolution of the genus arvicanthis (rodentia, muridae): inferences from complete cytochrome b gene sequences. | systematics of the genus arvicanthis, the african unstriped grass rat, are somewhat controversial. most recent taxonomic revisions list five to six species but the definition of some of these (arvicanthis dembeensis, arvicanthis nairobae, and arvicanthis niloticus) is uncertain. the complete mitochondrial cytochrome b gene (1140 bp) was sequenced for 20 specimens from throughout the range of the genus to determine the intrageneric genetic structure, construct a molecular phylogeny, and evaluate ... | 1998 | 9751921 |
