Clarksville, TN – There was something strange about the turtle, aside from its enormous head. Normally, the other species in the broad-headed group of map turtles confined themselves to a single major river system, butalum Josh Ennen (’05) knew this particular turtle was listed as living in two separate rivers.
“That was interesting, so I started looking at the genetics of the species,” he said. He compared populations of Graptemys gibbonsi (Pascagoula map turtle) from the Pascagoula and Pearl rivers.
