Figure 4From: Galápagos and Californian sea lions are separate species: Genetic analysis of the genus Zalophus and its implications for conservation management Phylogenetic networks of the genus Zalophus. Phylogenetic networks based on the mitochondrial control region showing relationships within the genus Zalophus: Californian sea lion (CSL), Galápagos sea lion (GSL), Japanese sea lion (JSL). Geographically different populations of the CSL are colour-coded: Gulf of California (light grey), Monterey Bay (dark grey), Channel Islands (black). A) Distance based network using the Neighbor-Net algorithm. B) Parsimony based median joining network shown for a minimum split weight of two.Back to article page
