Human-black bear interactions in Missoula Montana
… significant for many species, including American black bears (Ursus americanus). Human-black bear interactions (HBI) resulting in property damage, injury or death to humans, or fear of injury or death to humans are increasing in number and extent throughout North America, and wildlife management …

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, …

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 …

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 …

Designing against habitat loss: Facilitating movement of the Louisiana black bear
… support the continued survival of the Louisiana black bear (Ursus americanus luteolus), and preserve and protect the greater ecological communities of the bottomland hardwood forests that it occupies, this thesis proposes a catalog of design interventions that facilitate (1) the connectivity of …

Habitat requirements of the black bear in Dare County, North Carolina
A black bear habitat requirements study was performed in Dare County, North Carolina from March, 1973 through February, 1974. Four adult male bears were radio-collared and their movements monitored. Two removed their collars within 2 weeks of release, while another's collar malfunctioned. …

Reproductive biology and denning ecology of Virginia's exploited black bear population
… reproductive biology and denning ecology of black bears (<i>Ursus americanus</i>) were investigated in the George Washington and Jefferson National Forests, Virginia. The average age of captured bears was 4.88 years (SE=0.43, n=64) and 2.72 years (SE=0.19, n=127) for females and males, …

THE GUT MICROBIOTA OF A WILD AMERICAN BLACK BEAR (Ursus americanus) POPULATION
… 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 relationships, I …

Influence of gypsy moth induced oak mortality on a black bear population
… 1990 - November 1993 I measured the responses of black bears (Ursus americanus) in Shenandoah National Park (SNP), Virginia to gypsy moth (Lymantria dispar) induced oak (Quercus spp.) mortality. Oak species composed >50% of the forest canopy of SNP, and oak mortality rates ranged from 1- ≥48%. I …

Survival, Home Range and Spatial Relationships of Virginia's Exploited Black Bear Population
Eighty-three (21M, 62F) of 194 black bears captured during 1994-1996 were equipped with radio collars. Annual survival rates estimated with Kaplain-Meier staggered entry approach for radio collared adult females, adult males, subadult females, and subadult males were 95.3, 100.0, 90.4 and 50.0% …

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 …

NONINVASIVE GENETIC SAMPLING REVELAS BLACK BEAR POPULATION DYNAMICS DRIVEN BY CHANGES IN FOOD PRODUCTIVITY

Ecology and Structure of Black Bear (Ursus americanus) Populations in the Interior Highlands of Arkansas
… by other 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 …

Seasonal Reproduction in the Male Black Bear Ursus Americanusc and Male Polar Bear Ursus Maritimus
Both the black bear (Ursus americanus) and polar bear (Ursus maritimus) are long day seasonal breeders. Males undergo testicular regression during the non-mating season and testicular recrudescence during the pre-mating season. The present investigation was undertaken to begin to study the role of …

Visitor Perceptions of Black Bear Management Options in Big South Fork National River and Recreation Area
<p>Human/bear interactions will continue to increase as humans continue to live and recreate in closer proximity to bear habitat. One area positioned for a marked increase in human/bear interactions is Big South Fork National River and Recreation Area (BISO). To make decisions on the best …
