【 摘 要 】

Studying the ecology of terrestrial turtle species provides understanding of their spatial needs. Radio-telemetry was used to study the home range size, movement, habitat use, and nesting of Terrapene carolina. Minimum Convex Polygons (MCP) and Kernel Density Estimates at 95, 75, and 50% were used to measure home range size. Mean home range size was 7.4 ha (MCP) and 5.3 ha (95% Kernel). On average 76% of MCPs were overlapped by other radioed individuals. The home ranges were randomly distributed across the study site (p= 0.12, α= 0.05). Mean daily straight-line distance traveled was 31.5 meters. Most turtles traveled to locations that displayed clustered patterns. Turtles were most frequently radio-located to upland forests. In 2008, twelve Terrapene carolina were observed nesting. Nesting conditions and incubation temperatures were measured. Ten T. carolina nests were caged to protect from depredation and the mean hatching success for these nests was 85%.
