“You are what you eat.” The old adage is especially true when it comes to painted turtles. Dr. John Steffen assistant professor of biology at Shepherd University in West Virginia has been researching and studying the effect of dietary carotenoids on blood health and spot and stripe color in Painted Turtles. His research is shedding new light on sexual dichromatism in the species – why males look different than females.

The NHSM Herp Club is excited to host Dr. Steffen as the speaker at the October club meeting online via Zoom. These meetings are open to all. We do ask for a small donation from non-club members. Better yet – consider becoming a member.

John Steffen obtained his Ph.D from Auburn University. He is an ecologist interested in reptile and amphibian biology and conservation, who answers questions about how these organisms interact with their environment. He has performed research which attempts to understand how plants influence distributions of desert lizards, how the color of male tropical lizards (e.g., Anolis) throats influence individual reproductive success, and how aquatic plant diets contribute to spot and stripe color in Painted Turtles.
