The impact of climate change on the structure of Pleistocene mammoth steppe food webs

, 2013
Species interactions shape predator-prey networks, impacting community structure and, potentially, ecological dynamics. It is likely that global climatic perturbations that occur over long periods of time have a significant impact on species interactions

Where Dinner Roams: The Role of Feral Horses as a Resource Subsidy for Wolves and Cougars in West‐Central British Columbia

Ecology and Evolution, Volume 16, Issue 2, February 2026.
In west‐central British Columbia, large populations of feral horses overlap with native species like caribou and predators such as wolves and cougars, potentially disrupting predator–prey dynamics. Between 2019 and 2025, researchers documented multiple instances of wolf and cougar predation on feral horses—the first such confirmed cases in the region ...

Analyses of Brown Bear (Ursus arctos Linnaeus, 1758) activity in natural conditions and captivity [PDF]

, 2018
Hrvatska je dom mrkom medvjedu, najvećem europskom grabežljivcu. Naša netaknuta priroda omogućila je opstanak medvjeda u šumovitim planinskim područjima na Dinarskom gorju.

Neonate mortality in mountain caribou: Patterns of predation during onset of a wolf reduction program

The Journal of Wildlife Management, Volume 90, Issue 2, February 2026.
We used an individual‐based movement method, supported by camera trap data, to assess changes in neonate caribou mortality patterns before and after wolf reduction began in the Itcha‐Ilgachuz mountain caribou subpopulation range, British Columbia, Canada.

Validation of grizzly bear hair hormone profiles as a tool to monitor population demographics

The Journal of Wildlife Management, Volume 90, Issue 2, February 2026.
We measured 16 steroid and thyroid hormone concentrations in grizzly bear hair to predict sex, age class, and reproductive status. Models were highly accurate when predicting sex and age class and showed promise for assessing reproductive status. Results illustrate the potential for hair hormone profiles as non‐invasive population monitoring tools ...

A capture–recapture framework for combining biologging data with physical captures to decompose and estimate demographic rates: Simulations across life cycles and application to polar bears

Methods in Ecology and Evolution, Volume 17, Issue 2, Page 585-597, February 2026.
Abstract Estimating demographic rates of wild populations is critical to understanding their dynamics but can be challenging because large amounts of data are required, and parts of the life cycle of individuals may be unobserved. In numerous research programmes, capture–recapture (CR) data and biologging data are collected in parallel.

Desgaste dentario e ingestión de partículas minerales en osos actuales y extintos del Norte de España [PDF]

, 2001
[Abstract] The dental morphology of the cave bear Ursus spelaeus (Rosenmuller & Heinroth, 1794) indicates its specialisation as a vegetation eater. Although vegetal matter plays also an important role in the diet of most living bears, the dental wear ...

Emotional and attitudinal responses to social media depictions of human–wildlife interactions at wildlife tourist attractions

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract Wildlife tourist attractions (WTAs) can permit interactions between humans and wildlife that are detrimental to the animals’ welfare and species conservation. Social media portraying human–wildlife interactions could affect people's perceptions of their acceptability and desirability or stimulate demand for detrimental practices.
