A) Neighbour-joining tree of mitochondrial DNA showing genetic relationships among rookeries of Galápagos sea lions

Genetic distances between rookeries are based on corrected mean pair-wise sequence comparisons of the mitochondrial control region. B) 50 percent Neighbour-joining bootstrap consensus tree based on Goodman's Rst at the rookery level for 22 microsatellite loci. Bootstrap support values (5000 replicates) are shown above the nodes.
