Phylogeography of the Malagasy ring-tailed mongoose, Galidia elegans, from mtDNA sequence analysis


Bennett, C E; Pastorini, J; Dollar, L; Hahn, W J (2009). Phylogeography of the Malagasy ring-tailed mongoose, Galidia elegans, from mtDNA sequence analysis. Mitochondrial DNA, 20(1):7-14.

Abstract

The ring-tailed mongoose (Galidia elegans) represents one of the most widely distributed mongooses in Madagascar; however, we know little about the ecology of this seemingly ubiquitous species. Currently, G. elegans is divided into three recognized subspecies--G. e. elegans, G. e. dambrensis, and G. e. occidentalis--based on differences in pelage coloration between the distinct geographic locations. We used intraspecific DNA variation to describe the phylogenetic relationships among the described subspecies. Approximately 550 base pairs of the mitochondrial DNA control region were analyzed from 19 G. elegans specimens representing all three subspecies sampled from across the species' geographic range. Sequence data from outgroup taxa were included for comparison. Examination of the recovered sequences revealed a strongly supported distinct genetic signature in the western region of the island, but remained inconclusive with respect to supporting the designation of the northern and eastern 'subspecies' for treatment as divergent intraspecific units for management.
