Evolutionary Relationships Among Duiker Antelope (Bovidae: Cephalophinae), Anne Johnston
Evolutionary Relationships Among Duiker Antelope (Bovidae: Cephalophinae), Anne Johnston
University of New Orleans Theses and Dissertations
Duikers are a species rich subfamily of threatened African antelope whose recent origin poses a challenge to the molecular identification of taxa and estimation of their phylogeny. I test the ability of DNA barcodes to identify all taxa within this group. I then use mitochondrial and nuclear genes to estimate a multi-locus species tree and to date divergence times. DNA barcodes are unable to distinguish many sister taxa, calling into question the utility of barcodes for the regulation of duiker trade or in identification of field-collected feces. The multi-locus phylogeny provides support for the relationships among major duiker lineages and …
