| dna-based and geometric morphometric analysis to validate species designation: a case study of the subterranean rodent ctenomys bicolor. | the genus ctenomys (rodentia: ctenomyidae) shows several taxonomic inconsistencies. in this study, we used an integrative approach including dna sequences, karyotypes, and geometric morphometrics to evaluate the taxonomic validity of a nominal species, ctenomys bicolor, which was described based on only one specimen in 1912 by miranda ribeiro, and since then neglected. we sampled near the type locality assigned to this species and collected 10 specimens. a total of 820 base pairs of the cytochro ... | 2013 | 24301764 |
