Habitat Selection by Brown Bears with Varying Levels of Predation Rates on Ungulate Neonates

Diversity, 2021
In northern Eurasia, large carnivores overlap with semi-domestic reindeer (Rangifer tarandus) and moose (Alces alces). In Scandinavia, previous studies have quantified brown bear (Ursus arctos) spring predation on neonates of reindeer (mostly in May) and

Chewing lice Trichodectes pinguis pinguis in Scandinavian brown bears (Ursus arctos)

International Journal for Parasitology: Parasites and Wildlife, 2016
In April 2014 and 2015, we noted localized alopecia (neck, forelimbs, and chest) and hyperpigmentation on two adult brown bears (Ursus arctos) captured in central-south Sweden for ecological studies under the Scandinavian Brown Bear Research Project.

Human–bear conflict in Alaska: 1880–2015

Wildlife Society Bulletin, 2018
We present an analysis of human–bear (Ursus spp.) conflicts that occurred in Alaska, USA, from 1880 to 2015. We collected 682 human–bear conflicts, consisting of 61,226 data entries, from various sources available to us.

Non‐invasive mark–resight surveys for brown bears: Incorporating spatial information to improve landscape‐scale monitoring of density and distribution

Ecological Solutions and Evidence, 2023
Effective wildlife monitoring and management are reliant on unbiased estimators of population parameters. Most standard survey approaches ignore spatial pattern in the data although spatial relationships can be leveraged to produce more efficient designs

Movement ecology of brown bears (Ursus arctos) in the Romanian Eastern Carpathians

Nature Conservation, 2018
Brown bear movement patterns are driven by their opportunistic feeding behaviour, with their complex life history and seasonality playing an important role in habitat selection.

Analyses of key genes involved in Arctic adaptation in polar bears suggest selection on both standing variation and de novo mutations played an important role

BMC Genomics, 2020
Background Polar bears are uniquely adapted to an Arctic existence. Since their relatively recent divergence from their closest living relative, brown bears, less than 500,000 years ago, the species has evolved an array of novel traits suited to its ...

DISSEMINATION OF TRICHINELLOSIS (TRICHINELLA RAILLIET, 1895) IN PREYING MAMMALS WITHIN YAKUTIA AREA

Российский паразитологический журнал, 2016
Materials and methods. Epizootic situation and distribution of trichinellosis in carnivorous mammals (wolf, fox, white bear, brown bear, wolverine, lynx) in the territory of Yakutia were studied. Trichinellosis was detected in five of six examined animal

Integrating sign surveys and telemetry data for estimating brown bear (Ursus arctos) density in the Romanian Carpathians

Ecology and Evolution, 2017
Accurate population size estimates are important information for sustainable wildlife management. The Romanian Carpathians harbor the largest brown bear (Ursus arctos) population in Europe, yet current management relies on estimates of density that lack ...

The king of the forest: Local knowledge about European brown bears (Ursus arctos) and implications for their conservation in contemporary Western Macedonia

Conservation & Society, 2011
From a conservation point of view, Macedonia′s brown bear (Ursus arctos) population appears to be a key link in the distribution of one of Europe′s largest brown bear populations, the Dinaric-Pindos population. The lack of information concerning the bear

Phylogeography, genetic diversity, and connectivity of brown bear populations in Central Asia.

PLoS ONE, 2019
Knowledge of genetic diversity and population structure is critical for conservation and management planning at the population level within a species' range.
