Abstract Food availability influences movements, population dynamics, and harvest of black bears (Ursus americanus) in the Appalachian Mountains. We compared combinations of hard and soft mast indices to black bear non-hunting mortalities in West Virginia, USA, 1980–2004. Mast conditions were inversely related to non-hunting black bear mortalities. We constructed regression equations to predict non-hunting bear mortalities and used Akaike's Information Criterion (AIC) to compare fit of each… 

Relationship of Acorn Mast Production to Black Bear Population Growth Rates and Human—Bear Interactions in Northwestern South Carolina

Abstract Acorns represent a critical pulsed food source for American Black Bears (Ursus americanus) in the southern Appalachians, and represent their primary hibernation reserves. We used 20 years

Influence of whitebark pine decline on fall habitat use and movements of grizzly bears in the Greater Yellowstone Ecosystem

The wide diet breadth and foraging plasticity of grizzly bears likely allowed them to adjust to declining WBP, and the reduction in mortality risk historically associated with use of secure, high-elevation WBP habitat may be diminishing for bears residing in multiple-use areas.

Food habits of a small Florida black bear population in an endangered ecosystem

Abstract The Highlands–Glades subpopulation (HGS) of Florida, USA, black bears (Ursus americanus floridanus) is small, genetically depauperate, and resides primarily within the endangered Lake Wales

Population ecology, residents' attitudes, hunter success, economic impact, modeling management options and retention time of Telazol of West Virginia black bears

The West Virginia Black Bear Research Project (WVBBRP) was initiated in 1972 to investigate population parameters, growth rates, home ranges, and habitat uses of a declining American black bear

Food habits of American black bears as a metric for direct management of human–bear conflict in Yosemite Valley, Yosemite National Park, California

Abstract The management of human–American black bear (Ursus americanus) conflict has been of significant concern for Yosemite National Park (YNP) personnel since the 1920s. Park managers implemented

Relationships among food availability, harvest, and human–bear conflict at landscape scales in Ontario, Canada

Abstract Managers of American black bears (Ursus americanus) must maintain populations to ensure viability and opportunities for sport harvest, and minimize human–bear conflict (HBC). Harvest is a

Stochasticity in Natural Forage Production Affects Use of Urban Areas by Black Bears: Implications to Management of Human-Bear Conflicts

It is suggested that bear use of urban areas is reversible and fluctuates with the availability of natural food resources, and that removal of urban individuals in times of food failures has the potential to negatively affect bear populations.

Using stable isotope analysis to estimate black bear (Ursus americanus) diet in Vermont

The black bear (Ursus americanus) is an iconic species with cultural, economic and ecological importance in Vermont, USA. Bears exhibit a highly variable diet, and few studies have described bear

Can frequent occurrence of Asiatic black bears around residential areas be predicted by a model-based mast production in multiple Fagaceae species?

Frequent bear occurrences in western Japan can be predicted by monitoring fewer Fagaceae species (the three that are dominant there) than would be required in West Virginia, USA, for example.

Population reduction by hunting helps control human–wildlife conflicts for a species that is a conservation success story

Long-term data indicated that conflicts can be kept in tolerable bounds by managing population size through hunting, but due to the bluntness of this instrument and deficiencies and uncertainties in monitoring and manipulating populations, it is wiser to maintain a population at a level where conflicts are socially-acceptable than try to reduce it once it is well beyond that point.

Relationship of mast production to big-game harvests in West Virginia

Food availability influences population demographics and harvest of wildlife species throughout the Appalachians, and various combinations of hard- and soft-mast indices were compared to white-tailed deer, eastern wild turkey, and black bear statewide harvests in West Virginia, USA, 1980–2002.

Influence of natural food abundance on black bear harvests in Minnesota

A simple survey to monitor food abundance across Minnesota's bear range, and used these data to interpret a 12-year record of hunting success and harvest composition, found that females in the harvest were related inversely to fall food abundance, particularly hazelnuts and acorns.

Denning Chronology of Female Black Bears: Effects of Food, Weather, and Reproduction

We studied factors affecting the chronology of denning by 104 female black bears ( Ursus americanus ) from three areas in Maine from 1982 to 1988. At two areas in northern Maine, entry into dens

Effects of mast and berry crop failures on survival, growth and reproductive success of black bears

Existing reports do not support the popular notion that black bears are able to secure an adequate diet each year, and instead of limiting populations below densities that can be supported by long term food supplies, social order may permit higher densities than otherwise might be possible.

Seasonal Foods and Feeding Ecology of Black Bears in the Smoky Mountains

Between June 1969 and January 1972, 75 stomachs and 1,025 scats from black bears (Ursus americanus) were collected from the Great Smoky Mountains National Park and vicinity for food content analysis.

Effects of Fall Hunting on Wild Turkey Populations in Virginia and West Virginia

Spring gobbler-only hunting is suggested for maximum growth in a wild turkey population and target areas closed to fall hunting are attributed to legal hunting.
