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, …

Systematic classification of black bears in the southeastern United States
… 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 (U. a. …

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 …

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 …

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 …

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

Survival, family breakups, and dispersal of yearling and subadult black bears in western Virginia
… and dispersal patterns for yearling and subadult bears in hunted black bear (Ursus americanus) populations in North America are scarce. We estimated survival rates of yearling and subadult black bears from a hunted population in western Virginia during 1999 - 2002. We captured and marked 307 …

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
… States have 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 …
