THE GUT MICROBIOTA OF A WILD AMERICAN BLACK BEAR (Ursus americanus) POPULATION
… to facilitate the harvest 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 …

Effects of Infanticide Risk and Timber Harvest on American Black Bear Space Use
<p>Space use is an important aspect of bear ecology that maybe influenced by infanticide risk and timber harvest. I used generalized linear mixed models (GLMM) to determine if female American black bear (<em>Ursus americanus</em>) space use was consistent with avoidance behavior to reduce …

The Importance of Multiple Study Areas in Landscape Genetics: The American Black Bear in the Rocky Mountains
… will likely reduce connectivity among many black bear populations across their distribution. I used individual-based landscape genetics analyses in 12 study areas in western Montana and northern Idaho to assess the influence of landscape features on gene flow among American black bears …

A Bear's Eye View: Insight on American Black Bear (Ursus americanus) Hibernation and Foraging Ecology in Virginia's Central Appalachian Mountains
… deforestation in the late 1800s and 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 …

Systematic classification of black bears in the southeastern United States
… assessed genetic variation within and between 18 American black bear (Ursus americanus) populations in the southeastern United States using multilocus DNA fingerprinting techniques (Hinf I restriction digests, Jeffreys’ 33.15 probe). Band-sharing data indicated that American black bear populations …

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 …

A DYNAMIC LANDSCAPE OF FEAR: HUMAN IMPACTS ON CARNIVORE COMMUNITIES
… explored variation in spatiotemporal activity of American black bear and bobcat, and assessed carnivore co-occurrence using camera trap data. I constructed diel activity density curves, applied multispecies occupancy models, and calculated attraction-avoidance ratios to describe relationships …

Phylogenetic inference using ancient environmental DNA
… two closely related species, Ursus arctos or the American black bear and Arctodus simus or the extinct giant short-faced bear. By comparing the ancient sequence against a modern reference panel of black bears and a high-quality fossil giant short-faced bear reference, I infer evolutionary …

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 …

Spatial and Temporal Relationships of Adult Male Black Bears to Roads in Northwest Montana, 2003-2004
… Spatial and Temporal Relationships of Adult Male Black Bears to Roads in Northwest Montana Chairperson: Dr. Elizabeth Crone Roads have direct and indirect consequences for wildlife. Vehicle collisions are a direct cost of roads on wildlife. Indirectly, roads may increase mortality of game species …

Population Ecology of Black Bears in the Alleghany Mountains of Virginia
The Cooperative Alleghany Bear Study (CABS) was a 10-year study conducted on 2 areas and designed to investigate the ecology of a hunted population of American black bears (Ursus americanus) in the Alleghany Mountains of western Virginia. Over the course of our research, we handled 1,041 individual …

Population abundance and genetic structure of black bears in coastal North Carolina and Virginia using noninvasive genetic techniques
… strategies for apparently high-density, growing black bear populations in the Roanoke-Neuse-Tar-Cape Fear ecosystem in coastal North Carolina and Virginia. In order to provide the scientific information necessary to develop these strategies, I investigated population densities and genetic …
