Stochasticity in natural forage production affects use of urban areas by black bears: implications to management of human-bear conflicts. [PDF]

PLoS ONE, 2014
The rapid expansion of global urban development is increasing opportunities for wildlife to forage and become dependent on anthropogenic resources.

Comparative Analysis of Olfactory Receptor Repertoires Sheds Light on the Diet Adaptation of the Bamboo-Eating Giant Panda Based on the Chromosome-Level Genome

Animals, 2023
The giant panda (Ailuropoda melanoleuca) is the epitome of a flagship species for wildlife conservation and also an ideal model of adaptive evolution. As an obligate bamboo feeder, the giant panda relies on the olfaction for food recognition.

An analysis of human–black bear conflict in Utah

Human-Wildlife Interactions, 2017
Conflict between black bears (Ursus americanus) and humans has occurred in Utah, but the records are largely incomplete. To document these events, the Utah Division of Wildlife Resources initiated a black bear sightings and encounters database in 2003 ...

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.

Coexistence or conflict: Black bear habitat use along an urban-wildland gradient

PLoS ONE, 2022
The urban-wildland interface is expanding and increasing the risk of human-wildlife conflict. Some wildlife species adapt to or avoid living near people, while others select for anthropogenic resources and are thus more prone to conflict.

Dietary ecology of the extinct cave bear: Evidence of omnivory as inferred from dental microwear textures [PDF]

Acta Palaeontologica Polonica, 2016
The diet of the extinct European cave bear, Ursus spelaeus, has widely been debated. Diverging from the extant brown bear (Ursus arctos) approximately 1.2 million years ago, the cave bear is one of the most ubiquitous fossil bears occurring in Europe ...

Black Bears Recolonizing Historic Ranges: Indiana Human–Bear Interactions

Human-Wildlife Interactions, 2018
Over a century after extirpation from Indiana, USA, 2 American black bears (Ursus americanus) were confirmed in the state during the summers of 2015 and 2016.

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).

Public Perceptions of Bears and Management Interventions in Japan

Human-Wildlife Interactions, 2017
Conservation of bears is a challenge globally. In Japan, Asiatic black bears (Ursus thibetanus) and brown bears (Ursus arctos) are considered a nuisance because of agricultural and property damage and personal human danger due to occasional human ...
