| Abstract |
|
Testudinidae Gopher Tortoises (Gopherus polyphemus) located on the Kennedy Space Center (KSC) in east-central Florida have been the subject of a long-term population study but little is known about the genetic structure of the population. Other studies across the species’ range have shown evidence that Gopher Tortoises have undergone population bottlenecks due to geographic isolation. We assessed the genetic diversity of Gopher Tortoises from five locations on KSC at six microsatellite loci in 96 individuals. Based on our analysis, the population does not subdivide into genetically distinct assemblages but appears to be one nearly continuous population (FST = 0.030). This suggests that natural movement and/or human relocation has maintained the population’s gene flow across sites on the KSC. In terms of population genetics, we recommend that the tortoises on KSC be managed as a single population until further genetic analyses are completed.
