Den‐Site Behavior of Bengal Foxes (Vulpes bengalensis) Reveals Persistent Use, Social Interactions, and Coexistence in Shared Spaces [PDF]

Ecology and Evolution
The Bengal fox (Vulpes bengalensis) is a small, den‐obligate, wild canid that faces growing pressures in non‐protected landscapes. In Bangladesh, the species is considered vulnerable, receives minimal conservation attention, and knowledge of many ...

Light-level geolocation as a tool to monitor polar bear (Ursus maritimus) denning ecology: a case study

Animal Biotelemetry, 2023
Background Monitoring polar bears is logistically challenging and expensive. Traditionally, reproductive history has been assessed using permanent marks from physically captured individuals, which requires assumptions about reproductive history based on ...

Brown bear denning habits in northeastern Türkiye

Global Ecology and Conservation
Denning behavior is essential for species that must survive difficult seasonal conditions when food is scarce. In the first denning study conducted in Türkiye, we investigated the denning habits of brown bears in the evergreen Sarıkamış forest in the ...

Locations of dens with respect to space use, pre- and post-denning movements of brown bears in the Russian Far East

Nature Conservation Research: Заповедная наука, 2021
Space use and the use of a den during the winter period as an adaptation of the brown bear (Ursus arctos) to increase survival during a period of food shortage, are important aspects of the ecology in the practice of the population management.

Increased Land Use by Chukchi Sea Polar Bears in Relation to Changing Sea Ice Conditions. [PDF]

PLoS ONE, 2015
Recent observations suggest that polar bears (Ursus maritimus) are increasingly using land habitats in some parts of their range, where they have minimal access to their preferred prey, likely in response to loss of their sea ice habitat associated with ...

Despotism and risk of infanticide influence grizzly bear den-site selection. [PDF]

PLoS ONE, 2011
Given documented social dominance and intraspecific predation in bear populations, the ideal despotic distribution model and sex hypothesis of sexual segregation predict adult female grizzly bears (Ursus arctos) will avoid areas occupied by adult males ...

Denning in brown bears

Ecology and Evolution, 2020
Hibernation represents an adaptation for coping with unfavorable environmental conditions. For brown bears Ursus arctos, hibernation is a critical period as pronounced temporal reductions in several physiological functions occur.

Analysis of movement recursions to detect reproductive events and estimate their fate in central place foragers

Movement Ecology, 2020
Background Recursive movement patterns have been used to detect behavioral structure within individual movement trajectories in the context of foraging ecology, home-ranging behavior, and predator avoidance.

Fine‐scale variation within urban landscapes affects marking patterns and gastrointestinal parasite diversity in red foxes

Ecology and Evolution, 2020
Urban areas are often considered to be a hostile environment for wildlife as they are highly fragmented and frequently disturbed. However, these same habitats can contain abundant resources, while lacking many common competitors and predators.
