Brown bear attacks on humans: a worldwide perspective. [PDF]

Sci Rep, 2019
AbstractThe increasing trend of large carnivore attacks on humans not only raises human safety concerns but may also undermine large carnivore conservation efforts. Although rare, attacks by brown bears Ursus arctos are also on the rise and, although several studies have addressed this issue at local scales, information is lacking on a worldwide scale.

Spatial patterns and ecological determinants of Himalayan brown bear distribution in the Trans-Himalayas of India [PDF]

Scientific Reports
The Trans-Himalayan region of Ladakh is home to the endangered Himalayan brown bear, a species that remains understudied in high-altitude environments. In the Indian Himalayas, brown bears are threatened by low population densities, and isolated, insular

Genetic Analysis of the Brown Bear Sub-Population in the Pindos Mountain, Central Greece: Insights into Population Status and Conservation [PDF]

Animals
Habitat fragmentation poses a significant threat to the existence and reproduction of large carnivores, such as brown bears, as it affects the genetic connectivity of populations and, consequently, their long-term viability.

Brown bear denning habits in northeastern Türkiye

Global Ecology and Conservation
Denning behavior is essential for species that must survive difficult seasonal conditions when food is scarce. In the first denning study conducted in Türkiye, we investigated the denning habits of brown bears in the evergreen Sarıkamış forest in the ...

Denning in brown bears [PDF]

Ecology and Evolution, 2020
Abstract Hibernation represents an adaptation for coping with unfavorable environmental conditions. For brown bears Ursus arctos, hibernation is a critical period as pronounced temporal reductions in several physiological functions occur. Here, we review the three main aspects of brown bear denning: (1) den chronology, (2) den characteristics, and ...

Genomic evidence for island population conversion resolves conflicting theories of polar bear evolution. [PDF]

PLoS Genetics, 2013
Despite extensive genetic analysis, the evolutionary relationship between polar bears (Ursus maritimus) and brown bears (U. arctos) remains unclear. The two most recent comprehensive reports indicate a recent divergence with little subsequent admixture ...

Hypothyroidism in hibernating brown bears

Thyroid Research, 2023
AbstractBrown bears hibernate throughout half of the year as a survival strategy to reduce energy consumption during prolonged periods with scarcity of food and water. Thyroid hormones are the major endocrine regulators of basal metabolic rate in humans.
