Home Range and Nocturnal Activity of the Ozark Hellbender
Radio-telemetric methods were used to determine home ranges and nocturnal activity of seven Ozark hellbenders, Cryptobranchus alleganiensis bishipi, in the North Fork of the White River, Ozark County, Missouri, during a 14 day period in August, 1979. The mean elliptical home range for combined …

Cheetah of the Serengeti Plains: A home range analysis
… areas in an historically reduced geographic range. Home range, a useful trait for threat assessment, species reintroduction, and population estimation, is plastic in cheetah with sizes ranging from 40 km2 to over 1000 km2 depending on location. Previous home range estimates for cheetah used …

Home range and activity in a Virginia population of Sceloporus undulatus
… in Virginia, was designed to determine whether home range size, home range overlap, and patterns of behavior reflected the requirements of polygyny. The lizards were seen most often on the piles of debris that characterized the study site. Home range size was most strongly influenced by the …

Home range, habitat use, behavior, and morphology of the Gettysburg vultures
… large (X̅ = 15,993 and 62,953 ha respectively) home ranges. Ninety five percent of radioed vulture activity was within 15 km of the location at which the birds were trapped. Although home range size was not different between species, turkey vultures had greater variation in home range size. …

Population, Home Range, and Dispersal of Red Foxes in East-Central South Dakota
The population, dispersal movements and summer home range of red foxes (Vulpes vulpes) were studied in east-central South Dakota during 1974 and 1975. The spring population density of foxes on a 23,319 ha study area declined from 9.2 families/township in 1974 to 7.6 families/township in 1975. …

Home range dynamics of black bears in the Alleghany Mountains of western Virginia
… Mountains of western Virginia. I examined home range dynamics of bears during 1994-2002 on 2 study areas that were approximately 160 km apart. I analyzed my data with 3 home range programs (AMA, HRE, and ABODE) and determined the HRE was the least biased and produced the most biologically …

Seasonal Habitat Use, Home Range, and Dispersal of Wild Turkeys in Southcentral South Dakota
Seasonal movements, home range, and habitat use of wild turkeys in south-central South Dakota were investigated using radio telemetry from summer 1984 to winter 1986. Spring dispersal from wintering sites ranged from 0.2 to 5.8 km (x = 2.8 km). Non-nesting females moved significantly (P ~ 0.05) …
