Global population genetic structure of the sequential hermaphrodite, dusky grouper (Epinephelus marginatus)

The dusky grouper Epinephelus marginatus is a large epinephelid species that occurs in the eastern and south‐western Atlantic and western Indian Oceans. Late maturity, protogynous hermaphroditism, site fidelity, and overfishing have all contributed to its demographic decline. Connectivity and demography within a broad sampling of dusky grouper populations throughout its distribution were assessed. To do so, genetic variation at 11 polymorphic...
