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.

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 ...

Identifying priority core habitats and corridors for effective conservation of brown bears in Iran

Scientific Reports, 2021
Iran lies at the southernmost range limit of brown bears globally. Therefore, understanding the habitat associations and patterns of population connectivity for brown bears in Iran is relevant for the species’ conservation.

Biomechanical consequences of rapid evolution in the polar bear lineage. [PDF]

PLoS ONE, 2010
The polar bear is the only living ursid with a fully carnivorous diet. Despite a number of well-documented craniodental adaptations for a diet of seal flesh and blubber, molecular and paleontological data indicate that this morphologically distinct ...

And yet, migration, population growth or mortality are not balanced among Cantabrian brown bear subpopulations. Reply to Blanco et al (2020).

PLoS ONE, 2021
In a recent paper, we presented new evidence and provided new insights on the status of Cantabrian brown bear subpopulations, relevant for this species conservation.

Urinary capillariosis in a free-ranging Marsican brown bear (Ursus arctos marsicanus)

International Journal for Parasitology: Parasites and Wildlife, 2018
Extraintestinal nematodes have been seldom investigated in the brown bear (Ursus arctos). In this study, a case of urinary capillariosis and bladder associated lesions is reported in a deceased free-ranging Marsican brown bear (Ursus arctos marsicanus ...
