title: Microsatellite loci confirm a lack of population connectivity among globally distributed populations of the tope shark Galeorhinus galeus (Triakidae).
abstract: This study used 11 polymorphic nuclear microsatellite loci to determine the population connectivity of five geographically isolated populations of tope shark Galeorhinus galeus (Africa, Australia, North America, South America and western Europe). Genetic analyses revealed significant structure among all populations indicating a lack of population connectivity. These findings indicate that globally distributed populations of G. galeus are isolated and should be managed as distinct, independent stocks.
