Sea Turtles, Terrapins, and Lionfish: Dr. Kathryn Craven on Coastal Georgia Conservation

Host Jessica Leigh Lebos welcomes Dr. Kathryn Craven, a Georgia Southern University professor, Tybee Marine Science Center board trustee, and researcher known for work with loggerhead sea turtles and diamondback terrapins.
Craven shares her path from growing up near the Northeast coast to landing a sea turtle research job on Jekyll Island in 1991, including renewing flipper-tagging efforts. She discusses Georgia nesting-season monitoring, increasing loggerhead nest numbers linked to conservation measures such as shrimp fishery regulations and beach protections, and emerging challenges like rising coyote predation, plus mitigation using nest screening and predator control (including feral hogs).
Craven highlights research on nest microbiomes (fungi and bacteria) and findings that most unhatched eggs show fertility. She explains the TERPS head-start program incubating terrapin eggs and releasing hatchlings to offset female road mortality on Highway 80. The conversation also covers teaching evolution misconceptions through student drawing, earlier humpback whale work on bubble-net feeding, and new collaborative DNA-based lionfish research tied to lionfish rodeos and outreach.
