Mapping trends of large and medium size carnivores of conservation interest in Romania

Annals of Forest Research, 2014
We analysed yearly estimates of population size data during 2001-2012 for five carnivores species of conservation interest (Ursus arctos, Canis lupus, Lynx lynx, Felis silvestris and Canis aureus).

Translational implications of bradyarrhythmia in hibernating brown bears

Physiological Reports, 2023
The brown bear Ursus arctos undergoes exceptional physiological adaptions during annual hibernation that minimize energy consumption, including profound decrease in heart rate, cardiac output, and respiratory rate. These changes are completely reversible

Bioclimatic, demographic and anthropogenic correlates of grizzly bear activity patterns in the Greater Yellowstone Ecosystem

Oikos, EarlyView.
Plasticity of diel activity rhythms may be a key element for adaptations of wildlife populations to changing environmental conditions. In the last decades, grizzly bears Ursus arctos in the Greater Yellowstone Ecosystem (GYE) have experienced notable environmental fluctuations, including changes in availability of food sources and severe droughts ...

What does coexistence mean? Insight from place‐based trajectories of pastoralists and bears encounters in the Pyrenees

People and Nature, EarlyView.
Abstract The recovery of large carnivores in Europe raises issues related to sharing landscape with humans. Beyond technical solutions, it is widely recognized that social factors also contribute to shaping coexistence. In this context, scholars increasingly stress the need to adopt place‐based approaches by analysing how humans and wildlife interact ...

Distribution of the brown bear (Ursus arctos marsicanus) in the Central Apennines, Italy, 2005-2014 [PDF]

, 2017
Despite its critical conservation status, no formal estimate of the Apennine brown bear (Ursus arctos marsicanus) distribution has ever been attempted, nor a coordinated effort to compile and verify all recent occurrences has ever been ensured.

Key gaps remain in the definition and application of keystone species concepts for fisheries management: A systematic scoping review

People and Nature, EarlyView.
Abstract A keystone species is one whose influence is disproportionate to its abundance, the absence of which would change the dynamics of an ecological or human community. Despite its widespread use in the scientific literature, there is a limited understanding of how the keystone concept is defined or measured, or applied in practice, and especially ...

Novel range overlap of three ursids in the Canadian subarctic

Arctic Science, 2019
We describe for the first time in the peer-reviewed literature observations of American black bear (Ursus americanus Pallas, 1780), grizzly bear (Ursus arctos Linnaeus, 1758), and polar bear (Ursus maritimus Phipps, 1774) at the same locations.

Anthropogenic food: an emerging threat to polar bears

Oryx, 2023
Supplemental food from anthropogenic sources is a source of conflict with humans for many wildlife species. Food-seeking behaviours by black bears Ursus americanus and brown bears Ursus arctos can lead to property damage, human injury and mortality of ...

Cameras do not always take a full picture: wolf activity patterns revealed by accelerometers versus road‐positioned camera traps

Remote Sensing in Ecology and Conservation, EarlyView.
Camera traps have become an increasingly popular non‐invasive alternative to animal‐attached devices for studying wildlife behaviour. This study compared wolf (Canis lupus) activity patterns derived from collar accelerometers and road‐positioned camera traps and revealed strong overall agreement but also important seasonal and diel mismatches between ...
