) in the Gulf of California (GoC) are thought to include dis-tinct populations based on limited dispersal and resulting genetic population struc-ture (Schramm-Urrutia 2002). Comparisons of mitochondrial DNA collected frompups located on seven GoC rookeries suggest three distinct populations occur withinthe GoC (Schramm-Urrutia 2002). Although marked 1-yr-old juveniles have beenidentified on islands far from their natal site (
