Phylogeography is a discipline concerned with various relationships between gene
genealogies—phylogenetics—and geography. The word “phylogeography” was coined in …

Haplotype phylogenies based on DNA sequence data are increasingly being used to test
traditional species-level taxonomies based on morphology. However, few studies have …

Race is generally used as a synonym for subspecies, which traditionally is a geographically
