Microsatellite analysis of population structure in the shortfin mako ( Isurus oxyrinchus)
Microsatellite analysis of the shortfin mako shark (Isurus oxyrinchus) revealed very weak evidence of population structure. Samples collected from the North Atlantic, South Atlantic, North Pacific, South Pacific, and Atlantic, and Pacific coasts of South Africa were screened at four microsatellite l...
