Summary: Southeastern Florida is a critical breeding ground for loggerhead sea turtles (Caretta caretta). While nest counts reveal that Palm Beach County hosts the highest density of loggerhead nesting in the state of Florida, little research has evaluated key life-history traits and habitat use of breeding loggerheads in this area. Clutch frequency refers to the number of nests a female sea turtle deposits within one breeding season and serves as a key measure of a female’s total reproductive output. This study aims to provide an accurate clutch frequency estimate for these animals by satellite tracking nesting loggerheads from their first nest of the season. Additionally, nest site fidelity and inter-nesting home-range estimates will be evaluated to understand the space use of breeding loggerheads in southeastern Florida. Elucidating in-water hotspots is imperative for developing effective conservation strategies aimed at loggerhead population recovery. Finally, females will be tracked back to their foraging grounds, allowing for comparisons of potential carry-over effects on reproductive output.
