News and Updates
February 22, 2023 - Dr. Fox is a coauthor on a new paper looking at the genetics of Atlantic Sturgeon in the Ogeechee River. One particularly interesting finding was that of the two distinct genetic clusters of fish (likely fall- and spring-spawners), only one cluster was represented in offshore mixed aggregations of sturgeon.
