Denning Ecology of Black Bears in a Southeastern Wetland

Journal of Wildlife Management, 1989
We investigated den characteristics and denning chronology of black bears (Ursus americanus) in the Great Dismal Swamp (GDS), a forested wetland in Virginia and North Carolina. We monitored 35 bears (26 F, 9 M) throughout the winters of 1984-85, 1985-86, and 1986-87.

Denning, metabolic suppression, and the realisation of ecological opportunities in Ursidae

Mammal Review, 2021
AbstractThrough realisation of ecological opportunities, populations and species can experience relaxed selection pressures, facilitating ecological release and leading to rapid speciation and morphological diversification. Behavioural plasticity in response to environmental change contributes to diversification by exposing individuals to novel ...

Reproductive and denning ecology of the Central Georgia American black bear population

Ursus, 2017
Abstract Understanding biological and ecological requirements of small populations of American black bears (Ursus americanus) is important for maintaining or promoting population growth. During 2012–2015, we studied reproductive biology, cub survival, and den selection of black bears in an isolated population in central Georgia, USA. We visited dens of

Denning Ecology of Florida Black Bears in North-Central Florida

Southeastern Naturalist, 2012
Abstract We studied the denning chronology, den type, and den-site characteristics of Ursus americanus floridanus (Florida Black Bear) in Ocala National Forest (ONF) and the adjacent residential area of Lynne, FL. We monitored 35 radio-collared females for 62 den years from 1999 through 2003.

Denning Ecology of Polar Bears in the Canadian Arctic Archipelago

Journal of Mammalogy, 1994
From April 1989 through June 1992, we studied the denning ecology of 45 female polar bears in the Canadian Arctic archipelago, around M'Clure Strait and Viscount Melville Sound. Activity level of pregnant females was significantly lower in July–August compared to solitary, nonpregnant females.

Den ecology of the Arctic fox in northern Alaska

Canadian Journal of Zoology, 1969
During July and August 1962, 50 Arctic fox dens were studied on The Teshekpuk Lake Section of the Alaskan Arctic Slope. Depth to permafrost and soil texture govern location of fox dens in low. ice-core mounds with a minimum mound height of 1 m necessary for the establishment of a successful den. Soil temperatures at den sites were higher than those in

Denning Ecology of Black Bears in the White River National Wildlife Refuge, Arkansas

Journal of Wildlife Management, 1997
Lack of adequate den sites may adversely affect cub survival and reproductive success in black bears (Ursus americanus). Management of remnant bear populations in the lower Mississippi floodplain necessitates understanding denning ecology. We monitored 23 radiotagged black bears for 33 den years from 1993 to 1995 in White River National Wildlife Refuge,

Denning Ecology and Movements of Coyotes in Maine during Pup Rearing

Journal of Mammalogy, 1985
Den attendance, movements, and home range of eight adult coyotes (Canis la- trans) attending pups were investigated during 1981-1983 in eastern Maine. Coyote families used several dens during pup rearing, and dens were frequently relocated following human disturbance. Six den entrances were oriented 120-236' from north.
