Molecular evidence of reproductive isolation in sympatric sibling species of mouse lemurs

Journal Article

Recent morphological and molecular phylogenetic studies of mouse lemurs (Microcebus) living in the western and southern regions of Madagascar have shown that specific diversity had been considerably underestimated. In large part, this underestimate was due to the lack of sufficient specimens from given localities to assess properly the level of phenotypic variation within and between populations. The accurate delineation of specific boundaries has no doubt been confounded by the diminutive size, nocturnal habits, and subtle morphological variation characteristic of mouse lemurs, which can make field identification of individuals problematic. We illustrate the use of molecular phylogenetic analysis to reveal reproductive isolation in two sympatric mouse lemur species, Microcebus murinus and M. griseorufus. Their documentation in the Berenty Private Reserve in the extreme south of Madagascar verifies the historically-broad distribution of Microcebus griseorufus, a species recently resurrected from synonomy.
