Retrieval of four adaptive lineages in duiker antelope: evidence from mitochondrial DNA sequences and fluorescence in situ hybridization.

Author information

Department of Zoology & Entomology, University of Pretoria, Pretoria, South Africa.


Independent molecular markers (mitochondrial DNA sequences from two genes and fluorescence in situ hybridization with satellite DNA sequences as hybridization probes) were employed to investigate phylogenetic relationships among duiker antelope. When analyzed singly or taken together, the molecular and cytogenetic data allowed for the delimitation of four adaptive groups: the conservative dwarfs which are basal, a savanna specialist which groups apart from the forest duikers, the giant duikers, and the red duikers. Within the latter, a further subdivision comprising an east African and a west African red duiker clade is evident. The placement of the endangered zebra duiker and Aders' duiker remains problematic. Several of the nomenclatural divisions in current use are questioned by our results. These include the recognition of Philantomba as genus name for the blue and Maxwell's duiker and that Harvey's duiker be relegated to a subspecies of the Natal red duiker. We place our results in a biogeographic context and argue that duiker speciation has been driven predominantly by habitat fragmentation which probably led to the disruption of gene flow between geographic populations.
