A new karyological variant of Oecomys (Rodentia: Sigmodontinae) and its phylogenetic relationship based on molecular data.

Genome - 1 Apr 2003

Belchior de Andrade Ana Flávia, Rodrigues Bonvicino Cibele

Abstract excerpt

A new karyological variant of the Sigmodontinae genus Oecomys was detected in specimens from Brazilian Pantanal. Karyologic analyses showed 2n = 72 and FN = 90, which differs from all known chromosomal complements of the genus. This new karyomorph showed distinctive morphological attributes and could not be attributed to any described Oecomys species. Molecular analysis using cytochrome-b sequence data suggested...
