Patterns of spatial distribution, diel activity and human-bear conflict of Ursus thibetanus in the Hindu Kush mountains, Pakistan

Global Ecology and Conservation, 2022
The Asiatic black bear (Ursus thibetanus) is an elusive mammal and its conservation is currently a challenge in Pakistan due to the negative interaction with human communities and habitat fragmentation.

Stochastically Fluctuating Black-Hole Geometry, Hawking Radiation and the Trans-Planckian Problem [PDF]

, 2000
We study the propagation of null rays and massless fields in a black hole fluctuating geometry. The metric fluctuations are induced by a small oscillating incoming flux of energy.

High genetic diversity and distinct ancient lineage of Asiatic black bears revealed by non-invasive surveys in the Annapurna Conservation Area, Nepal.

PLoS ONE, 2018
Asiatic black bears (Ursus thibetanus) have a widespread distribution in mountain landscapes, and are considered vulnerable globally, but are low-priority species for conservation in Nepal.

Florida Bears and Beekeeping

EDIS, 2019
This document discusses the interaction between black bears and beekeeping in Florida. It highlights the areas in Florida where black bear populations are concentrated and the frequency of bear depredations on apiaries.

Using an integrative mapping approach to identify the distribution range and conservation needs of a large threatened mammal, the Asiatic black bear, in China

Global Ecology and Conservation, 2021
Assessing a species’ threatened status and then developing specific conservation strategies accordingly rely heavily on knowing that species’ complete and accurate spatial distribution.

Unraveling the mystery of the glacier bear: Genetic population structure of black bears (Ursus americanus) within the range of a rare pelage type

Ecology and Evolution, 2020
Glacier bears are a rare grey color morph of American black bear (Ursus americanus) found only in northern Southeast Alaska and a small portion of western Canada.

Spatial patterns of reproduction suggest marginal habitat limits continued range expansion of black bears at a forest‐desert ecotone

Ecology and Evolution, 2023
Investigating spatial patterns of animal occupancy and reproduction in peripheral populations can provide insight into factors that form species range boundaries.

Survival and productivity of a low-density black bear population in Rocky Mountain National Park, Colorado

Human-Wildlife Interactions, 2017
Historically, Rocky Mountain National Park (RMNP) has supported a small black bear (Ursus americanus) population of low productivity. Increased visitor use of the park and development around its periphery could lead to a reduction in population viability

Using GIS-Based, Regional Extent Habitat Suitability Modeling to Identify Conservation Priority Areas: A Case Study of the Louisiana Black Bear in East Texas [PDF]

, 2013
State and federal recovery plans mandate that priority areas for future population expansion be identified within the historical range of the Louisiana black bear (Ursus americanus luteolus).

Applying spatially explicit capture–recapture models to estimate black bear density in South Carolina

Wildlife Society Bulletin, 2019
Population density is an important component of wildlife management decisions, but can be difficult to estimate directly for an itinerant, wide‐ranging species such as the American black bear (Ursus americanus).
