| Abstract |
|
An investigation of habitat use, home range, and seasonal movements of adult yellow-blotched map turtles (Graptemys flavimaculata) was conducted on the Pascagoula River in southeastern Mississippi. Females were found in deeper, faster water at greater distances from the shoreline in areas with fewer emergent snags than were males. Male distance from the shoreline was inversely correlated with surface current speed during the summer, but female distance was not. Male mean home range area was 1.12 ha; mean home range length was 1.8 km. Female mean home range area was 5.75 ha; mean home range length was 1.5 km. Home range areas and lengths did not differ significantly between the sexes. Graptemys flavimaculata was active in the study area throughout the year. Some turtles were relatively sedentary but others moved seasonally. Seasonal movements appeared to be associated with nesting (females), searching for receptive mates (males), or to avoid increased currents during winter (both sexes). Two females regularly moved into a cypress pond in early spring, presumably to increase their foraging opportunities.
