Shifting attitudes toward brown bears in Bulgaria: a longitudinal and regional analysis

Wildlife Biology, EarlyView.
Longitudinal research on public attitudes toward large carnivores is scarce, limiting our understanding of how human–wildlife coexistence evolves. This study aimed to bridge this gap by replicating a 2012 survey on attitudes toward brown bears Ursus arctos in four bear‐populated regions of Bulgaria.

Black Bears (Ursus americanus) versus Brown Bears (U. arctos): Combining Morphometrics and Niche Modeling to Differentiate Species and Predict Distributions Through Time

, 2017
Late Pleistocene American black bears (Ursus americanus) often overlap in size with Pleistocene brown bears (U. arctos), occasionally making them difficult to diagnose. Large U. americanus have previously been distinguished from U.

Adaptive harvesting of two trophic levels stabilises predator–prey dynamics. Simulations with Eurasian lynx and European roe deer

Wildlife Biology, EarlyView.
Europe has seen the recovery of many species of wild herbivores, which are now widespread across much of the continent. In addition, large carnivores are also recolonising many European countries. Most ungulates are managed through hunting, but natural predation can also have a significant influence in many areas.

Evolution of cranio-dental features and distribution of brown bear (Ursus arctos L., 1758) in Europe. [PDF]

, 2019
The study of the fossil remains of the brown bear (Ursus arctos, L. 1758) of the Pleistocene has always been extremely interesting for the vertebrate paleontologists. The discovery of bear material in different sites (fluvio-lacustrine and cave deposits),

Text-fig. 13. Shape morphospaces reproduced variation of mtt V in males (a) and females (b) when U. arctos, U. etruscus, U. rossicus and U. savini were excluded (sample centroids are marked, except centroid of U. s. ladinicus). Ellipses' horizontal and vertical projections onto axes are equal to sample mean (centroid) ± highest value – lowest value × 0.95. in Morphometric Analysis Of Metacarpal And Metatarsal Bones Of Cave Bears (Carnivora, Ursidae)

Ecological plasticity of denning chronology by American black bears and brown bears

Global Ecology and Conservation, 2019
Ecological plasticity may index the capacity of individuals, populations, and species to respond to stochasticity. Few studies have demonstrated mechanisms influencing expression of plasticity and less have addressed proximate and causal mechanisms at ...

A literature‐based framework for anticipating golden jackal Canis aureus colonisation: insights from Europe and a Swiss case study

Wildlife Biology, EarlyView.
The expansion of the golden jackal Canis aureus in Europe, caused mainly by habitat fragmentation, climate change and the decline of large carnivores until half a century ago, poses emerging challenges for newly colonised regions. With the arrival of a new species, potential effects on local animal communities, hunting, livestock husbandry or the ...

Epiphyseal fusion in brown bears: a population study of grizzlies (Ursus arctos horribilis) from Montana and Wyoming

, 2009
This contribution presents results of a study of the timing of appendicular epiphyseal fusion in brown bears (Ursus arctos) based on the visual examination of 86 modern skeletons of grizzlies (U. a.

Black bear density in Glacier National Park, Montana

Wildlife Society Bulletin, 2014
We report the first abundance and density estimates for American black bears (Ursus americanus) in Glacier National Park (NP), Montana, USA. We used data from 2 independent and concurrent noninvasive genetic sampling methods—hair traps and bear rubs ...
