Abstract The southeastern pocket gopher Geomys pinetis is absent from a large portion of its historical range. Translocation may represent a viable management technique to reestablish populations into suitable habitat. However, several aspects of the species' ecology are poorly understood, making development of an effective translocation approach challenging. Therefore, we used radiotelemetry to examine home range, survival, dispersal, and daily activity patterns of the southeastern pocket gopher in southwestern Georgia. We measured soil and vegetation characteristics within individual home ranges and examined relationships between home range size, habitat variables, and body mass. Mean home range size of 17 radio-tagged pocket gophers was 921.9 m2 (range = 43.4–2246.8 m2). Home range size was positively related to body mass, percent silt at a depth of 25 cm, and soil carbon content at 75 cm and was negatively related to percent sand at 25 cm, percent clay at 50 cm, and ground cover of grasses other than wiregrass Aristida beyrichiana. Survival rate was 0.78 (range = 0.50–1.00) over the 51-wk study, and we documented predation, likely by avian predators, on two individuals. Three individuals dispersed, with a maximum dispersal distance of 319.1 m (range = 143.2–319.1 m), the farthest known southeastern pocket gopher dispersal. Pocket gophers exhibited greater activity from 0000 to 0400 hours and from 1600 to 2000 hours, contrasting previous research that southeastern pocket gophers were equally active throughout the diel period. Our home range size estimates for southeastern pocket gophers are the first determined using radiotelemetry and are considerably smaller than previous estimates. Although we documented dispersal distances more than 300 m, the fragmented nature of current and restored habitats likely will prevent large-scale natural colonization. Our results provide information important for maximizing success in future southeastern pocket gopher translocation efforts.

AbstractThe burrowing ecology of 12 adult and nine juvenile Louisiana pine snakes, Pituophis ruthveni, was studied during 1995-1997 in north-central Louisiana, U.S.A. Significantly more adult burrows connected to pocket gopher (Geomys breviceps) tunnels than did juvenile burrows, although a relatively high number of adult and juvenile snake burrows were blind-ended. Significantly more adult snake burrows were located in pine plantations and grasslands and significantly less were located in clearcuts than expected. Significantly more juvenile snake burrows were located in pine plantations than expected. Adult and juvenile snake burrows were located in areas that had relatively less leaf litter and canopy closure than expected. Excavation behavior by P. ruthveni was stereotyped and similar to excavation behavior by the bullsnake, Pituophis catenifer sayi and the northern pine snake, Pituophis melanoleucus melanoleucus.
