Global Phylogeography with Mixed-Marker Analysis Reveals Male-Mediated Dispersal in the Endangered Scalloped Hammerhead Shark (Sphyrna lewini) 1 ¤ 2 3 3 4 Toby S. Daly-Engel * , Kanesa D.

A previous survey of maternal (mtDNA) markers demonstrated strong genetic partitioning overall (global WST = 0.749) and significant population separations across oceans and between discontinuous continental coastlines. Methodology/Principal Findings: We surveyed the same global range with increased sample coverage (N = 403) and 13 microsatellite loci to assess the male contribution to dispersal and population structure.
