|
The home-range, monthly and seasonal habitat use and hibernacula selection of eastern box turtles (Terrapene carolina carolina) were investigated in 2003 using radiotelemetric applications at two sites (West Rock Ridge and Mountain Road) located along the West Rock Ridge basalt trap rock ecosystem in Connecticut. Radio-tracked turtles were re-located an average of 61.6 times each from May until they entered hibernation in October. Turtle (n = 14) home-range size averaged 4.97 ha with a range from 0.99 - 16.2 ha. Female turtles (n = 7) had slightly smaller home-ranges (avg. 4.0 ha) than males (n = 7; avg. 6.74 ha). The general trends in monthly habitat use for West Rock Ridge (WRR) showed variable habitat use in May with late successional upland (LSU) habitats being preferred. In June there was a shift in the preferred habitat from LSU to open canopy wetlands (OCW). During the months of July, August, and September similar use of closed canopy wetland (CCW) and mature upland (MU) habitats were observed. During October there was a large shift to MU. Similar trends were seen in the seasonal habitat use at WRR with OCW being preferred in the spring, CCW and MU being preferred in early to late summer, with habitat preferences towards MU in fall. General trends in monthly habitat use for Mountain Road (MR) showed preferences towards early successional upland (ESU) habitats during May and June and ESU and MU habitats during the months of July and August. Habitat use shifted to predominately MU habitats during the months of September and October. Similar trends were seen in the seasonal habitat use at MR with ESU being preferred in the spring, ESU and MU in the early summer, and MU in late summer and fall. All turtles from both sites hibernated in mature upland habitats.
