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).

Modelling the surprising recolonisation of an understudied aquatic mammal in a highly urbanised area: fortune favoured the smooth‐coated otter in Singapore

Wildlife Biology, EarlyView.
Ever‐growing human activities present an active and continuing threat to many species throughout the world. Nevertheless, concerted conservation efforts in some regions have balanced these threats and allowed endangered species to recolonise former parts of their original ranges and reverse their decline.

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

Fallot's Tetralogy in a European Brown Bear (Ursus arctos) [PDF]

Journal of Wildlife Diseases, 2005
A congenital heart malformation was diagnosed in a free-ranging adult female European brown bear (Ursus arctos) found dead due to intraspecific violence. At necropsy, the heart had all four features of Fallot's tetralogy. No further malformations were identified in the animal, which was of normal size and weight for its age, in normal body condition ...

Monitoring GPS‐collared moose by ground versus drone approaches: efficiency and disturbance effects

Wildlife Biology, EarlyView.
Efficient wildlife management requires precise monitoring methods, for example to estimate population density, reproductive success, and survival. Here, we compared the efficiency of drone (equipped with a RGB camera) and ground approaches to detect and observe GPS‐collared female moose Alces alces and their calves. We also quantified how drone (n = 42)

Unraveling the impact of dog‐friendly spaces on urban–wildland pumas and other wildlife

Wildlife Biology, EarlyView.
As the most widespread large carnivore on the planet, domestic dogs Canis lupus familiaris can pose a major threat to wildlife, even within protected areas (PAs). Growing human presence in PAs, coupled with increasing pet dog ownership underscores the urgency to understand the influence of dogs on wildlife activity and health.

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.

A high‐altitude thermal infrared method for estimating moose abundance and demography in Rocky Mountain National Park, USA

Wildlife Biology, EarlyView.
Resource managers require accurate estimates of large herbivore abundance and demography to maintain ecological integrity. Common methods to count these species, including observations from low altitude helicopter flights, may conflict with other protected area management objectives and struggle to produce precise estimates for more cryptic species. To

Isolation and complete genome sequencing of rabies virus strain isolated from a brown bear (Ursus arctos) that attacked a human in Primorsky krai (November, 2014)

Вопросы вирусологии, 2016
An attack of a brown bear (Ursus arctos) on human was detected in November, 2014 in the Barabash village (Khasan region of the Primorski krai) located in close proximity to the national park Land of the Leopard. The bear was shot. The deviant behavior of
