Turtle Love has its roots in partnerships developed during the graduate research of our Scientific Director, Renato Bruno, a Brazilian biologist who has worked to conserve sea turtles since 2009. While studying aspects of the reproductive biology of green turtles (Chelonia mydas) nesting at Tortuguero National Park, Renato’s collaborations with friends and colleagues naturally evolved into an organization focused on community-based nesting beach protection. The objectives of the individual founders became the mission of the organization, and Turtle Love was born!
In 2018, working under the Sea Turtle Conservancy (STC) and Southeastern Louisiana University, Renato studied the phenology and hormonal regulation of the reproductive cycle of green turtles nesting at Tortuguero National Park. Expanding on his work in Tortuguero, Renato continues to investigate the reproductive biology as well as the nutritional ecology of green turtles in the greater Caribbean basin:
1) With Turtle Love in Costa Rica, where he studies the fluctuation of sex hormones throughout the nesting season and, in collaboration with the Global Male Sea Turtle Initiative, collects samples from mating turtles to study operational sex ratios and the genetic composition of this green turtle population.
2) In Nicaragua, where he collects data on the reproductive state and diet of green turtles at foraging grounds off the Miskito Coast, where a legal harvest of sea turtles still occurs (research funded by Renato’s National Geographic Early Career Grant).
3) As part of his PhD research at the Archie Carr Center for Sea Turtle Research (ACCSTR) at the University of Florida.
The results of this research will help refine population size estimates, understand the effects of climate change on sea turtle reproductive output, and inform management strategies to reduce human impacts on this green turtle population.
