The Natural History & Distribution of Riverine Turtles in West Virginia Thesis submitted to the Graduate College of Marshall University In partial fulfillment of the requirements for the degree of Master of Science in Biological Sciences By Linh Diem Phu Dr. Thomas K. Pauley, Ph.D., Committee Chairperson Dr. Dan Evans, Ph.D. Dr. Suzanne Strait, Ph.D. Marshall University May 2010 Abstract Turtles are unique evolutionary marvels that evolved from amphibians and developed their protective shelled form more than 200 million years ago. In West Virginia, there are 10 native species of turtles, 9 of which are aquatic. Most of these aquatic turtles feed on carrion and dead plant matter, in the water and essentially "clean" our water systems. Turtles are long-lived animals with sensitive life stages that can serve as both long-term and short-term bioindicators of environmental health. With the increase in commercial trade, habitat fragmentation, degradation, destruction, there has been a marked decline in turtle species.
