Summary: Genetics has been a useful tool in studying sea turtles and delineating populations for conservation and management. Over the last 20 years there has been a surge in genetic research on other species, yet these emerging techniques have not been applied widely to sea turtles. Using next-generation restriction-site associated DNA (RADSeq), we will delve into the intricacies of genetic diversity, population structure, and demographic history of leatherback sea turtles (Dermochelys coriacea). We aim to quantify genetic diversity within the Florida leatherback through nucleotide diversity and assess inbreeding with runs of homozygosity analysis. Concurrently, we will estimate current and historical effective population sizes by applying coalescent-based models to track genetic lineages over time. This investigation is timely and vital, as genetic diversity underpins species' resilience and adaptability to environmental changes, a pressing concern for the vulnerable Florida leatherback population. This study stands to fill critical knowledge gaps regarding the genetic constitution and evolutionary trajectory of leatherbacks, particularly in Florida. By leveraging the data obtained, we can bolster conservation strategies. Furthermore, the techniques and insights gained from this research will be applicable to broader conservation contexts, benefiting other populations and marine species.
