CheloniaCast sits down with Dr. Fredric Janzen. Dr. Janzen is the former director of the W.K. Kellogg Biological Station and a current professor in Michigan State University's Department of Fisheries and Wildlife. Dr. Janzen uses turtles as a model system to study deeper questions in the study of life, development, and evolution. The conversation covers various aspects of Dr. Janzen’s experiences in the study of turtle life history, evolution, and adaptation. From temperature sex determination considering climate change, reproductive behaviors, differences in fecundity between species, and egg/hatching adaptations, the conversation is wide-ranging.

On this episode of CheloniaCast we are joined by both Brent Fannin and Chase Pirtle, the producers behind the documentary Gopher Games: a short documentary focusing on the potential grim fate of the Gopher Tortoises in Florida. Chase is the Director of the 100-acre Ashton Preserve and has diverse experience in wildlife conservation and study across various states in the U.S. Brent is an award-winning documentary filmmaker, drone pilot, educator, and founder of Golden Hawk Drones. The conversation dives into the process of producing the Gopher Games film, and details some of the major takeaways for both Brent and Chase. A prominent theme of the conversation is the fact that the majority of the commissioners of the Florida Fish and Wildlife Conservation Commission are developers, and why this is not a fair situation for the Gopher Tortoise. The value of the Gopher Tortoise both intrinsically, and instrumentally, is discussed at length as well as the imminent threats they are facing.

CheloniaCast is joined by Jordan Donini, Professor of Biology at Florida Southwestern State College. Jordan is an accomplished researcher with focuses on life history, reproductive biology, spatial ecology, and seasonal movements of turtles. His work has spanned across multiple fascinating chelonian hot spots, notably Costa Rica and the Southeastern United States. The conversation ranges from Jordan’s experiences in the field as well as unique aspects of turtle ecology uncovered by Jordan’s research. Phenomena such as Gopher Tortoises being gravid in the winter, box turtles eating crabs, the cryptic nature of the Florida Mud Turtle, and a Florida Softshell Turtle with an additional cloaca are discussed.

For the past few years Jordan has organized Herpeton, The Florida Herpetology Conference, the premier symposium highlighting the immense amount of herpetological research and conservation in the Sunshine State.

CheloniaCast is joined by Michela Coury, Freshwater Turtle Biologist for the Massachusetts Department of Fish and Game and all-around turtle biologist and researcher. Michela did her master’s thesis on Spotted Turtle ecology and movement and has vast field experience with various other North American turtle species. In her current position with the Massachusetts Department of Fish and Game she is tasked with protecting the state’s turtle populations through habitat management, fieldwork, data collection/analysis, and outreach. The conversation dives into Michela’s upbringing into turtles, experiences in the field and the many rewarding aspects of the world of turtle conservation. There is also much discussion about Spotted Turtle home range, the use of R in spatial analysis, and some wild fieldwork stories.

CheloniaCast is joined by Brad Nahill, cofounder and president of SEE Turtles, a unique conservation group pairing ecotourism with turtle conservation and focusing on the legacy of J Nichols. Brad has authored book chapters, blog posts, scientific abstracts, and case studies all with a focus on sea turtles and their plight. The conversation covers Brad’s experience founding SEE Turtles, and all the early chalenges involved in forming an ecotourism project that supports wildlife. The interesting component of this episode is the uniqueness of the conservation approach SEE Turtles champions. Uniting profit and conservation rather than the typical negative dynamic of profit and vulnerable fauna, and serving as a way to unite communities with their local sea turtle populations. There is also heavy emphasis on the legacy and impact of the late J Nichols, and his integral role in developing SEE Turtles and the Billion Baby Turtles initiative.
