Population dynamics of Virginia's hunted black bear (Ursus americanus) population
The Cooperative Alleghany Bear Study (CABS) was initiated in 1994 by the Virginia Department of Game and Inland Fisheries (VDGIF) and the Virginia Polytechnic Institute and State University (VPI&SU) to investigate population dynamics on Virginia's hunted bear population. CABS personnel handled 746 …

THE GUT MICROBIOTA OF A WILD AMERICAN BLACK BEAR (Ursus americanus) POPULATION
… of wildlife such as American black bear (<em>Ursus americanus</em>). Additionally, much of our knowledge of wildlife-GMB relationships is based on studies of colon GMB communities derived from the feces of captive specimens. To better understand wildlife-GMB relationships, I first aimed to …

Estimating Population Numbers of Black Bears (Ursus Americanus) in Eastern Kentucky Using Microsatellite Analysis
Black bears (Ursus americanus) occur sporadically in eastern Kentucky, and there is some evidence that a breeding population exists. In order to establish management practices to enhance the black bear population in Kentucky, information about this population is needed. However, until recently, no …

Ecology and Structure of Black Bear (Ursus americanus) Populations in the Interior Highlands of Arkansas
… means contributed to the decline of black bears (Ursus americanus). Bears were extirpated from the majority of the region by the 1940's Oklahoma by 1915 and from Missouri by 1931. From 1958-1968, the Arkansas Game and Fish Commission undertook a reintroduction to the Ouachita and the Ozark …

Are black bears (Ursus americanus) effective seed dispersal agents? With a little help from their friends.
Black bears (Ursus americanus) are generally considered effective seed dispersal agents for fleshy-fruited plants because they can consume hundreds of fruits at once and have large home ranges. Seedlings can emerge from fecal piles, but if any seeds are removed from feces by rodents, it is often …

Seasonal movements, habitat selection, and food habits of black bears (Ursus americanus) in Shenandoah National Park, Virginia
… habits, and habitat selection of black bears (<i>Ursus americanus</i>) in Shenandoah National Park, Virginia were studied from May 1982 to April 1985. A total of 47 collared bears, including 25 adult females, 17 adult males, and 5 subadult males < 3.5 years old, was located 3973 times during the …

Assessment of Physiological Challenges in Overwintering Black Bears (Ursus americanus): Active Gestation, Neonatal Growth, and Skeletal Muscle Conservation
The American black bear (ABB) (Ursus americanus) exhibits physiological strategies highly synchronized with the environment. Such strategies enable bears to exploit food resources when available and survive the winter months by hibernating without ingesting food or water. However, there are …

Evaluating the Effectiveness of Population Reconstruction for Black Bear (Ursus americanus) and White-Tailed Deer (Odocoileus virginianus) Population Management
… deer (Odocoileus virginianus) and black bear (Ursus americanus). Downing reconstruction (Downing 1980) was the most commonly used reconstruction technique among biologists participating in this study. Based on a comprehensive literature review and discussions with state biologists, I decided to …

A Bear's Eye View: Insight on American Black Bear (Ursus americanus) Hibernation and Foraging Ecology in Virginia's Central Appalachian Mountains
… early 1900s, American black bear populations (Ursus americanus, hereafter black bear) were low across most of Virginia. The Department of Wildlife Resources (VADWR) and the United States Forest Service worked to rebuild wildlife habitat in the state, leading to recovery of bears. While some …

Ecology and physiology of a black bear (Ursus americanus) population in the Great Dismal Swamp and reproduction physiology in the captive female black bear
Ecology and physiology of black bears in Great Dismal Swamp (GDS) National Wildlife Refuge and surrounding area, a forested wetland in eastern Virginia and northeastern North Carolina, were studied from April 1984 to March 1987. A total of 101 bears (71M, 30F) were captured 120 times. Males …

Temporal, Spatial, and Environmental Influences on the Demographics and Harvest Vulnerability of American Black Bears (Ursus americanus ) in Urban Habitats in New Jersey, Pennsylvania and West Virginia
… addressed the spatial ecology of black bears (Ursus americanus) in urban and suburban habitats, and there is limited information regarding black bear space use, habitat selection, and harvest vulnerability. I assessed the harvest vulnerability, home range size, and spatial ecology of black …

Determination of denning bear isolate and its effects on non-denning guinea pigs
The North American Black Bear (Ursus americanus) fasts for five months in the winter. While maintaining body temperature at 35$\sp\circ$C, the bear requires no food or water and does not urinate or defecate. Anabolic functions such as protein synthesis and bone remodeling continue. Female bears …

Aspects of Reproduction and Cub Survival in a Hunted Population of Virginia Black Bears
We measured black bear (Ursus americanus) reproduction and cub survival during 1994 - 1998, and 1995 - 1999, respectively, in the George Washington and Jefferson National Forests in Virginia to determine age-specific and overall cub production and cub survival. We observed females in estrus between …

SPATIALLY EXPLICIT MODEL OF AREAS BETWEEN SUITABLE BLACK BEAR HABITAT IN EAST TEXAS AND BLACK BEAR POPULATIONS IN LOUISIANA, ARKANSAS, AND OKLAHOMA
<p>Although black bears <em>(Ursus americanus, Ursus americanus luteolus)</em> were once found throughout the south-central United States, unregulated harvest and habitat loss resulted in severe range retractions and by the beginning of the twentieth century populations in Oklahoma, Louisiana, …
