Free rein: Are feral horses competing with native ungulates in British Columbia?

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 3, April 2026.
We investigated little‐studied feral horses in west‐central British Columbia, Canada, as a potential competitor for native moose and mule deer. We did not find strong evidence that feral horses exclude moose or deer from habitat or resources at a large landscape scale or smaller spatiotemporal patch scale.

Genetic turnovers and northern survival during the last glacial maximum in European brown bears

open access: yesEcology and Evolution, 2019
The current phylogeographic pattern of European brown bears (Ursus arctos) has commonly been explained by postglacial recolonization out of geographically distinct refugia in southern Europe, a pattern well in accordance with the expansion/contraction ...

The Preservation of Muscle Mitochondrial Machinery During Hypometabolic Hibernation in Scandinavian Brown Bears (Ursus arctos)

open access: yesActa Physiologica, Volume 242, Issue 4, April 2026.
ABSTRACT Aim Unlike humans, brown bears (Ursus arctos) uniquely preserve skeletal muscle mass and function during months of hibernation despite prolonged fasting and inactivity. We investigated how mitochondrial energetics respond in skeletal muscle to support this remarkable resilience.

Anthropogenic Infrastructures Shape Brown Bear Movements in Human‐Modified Landscapes

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
Human activities are major drivers of changes in animal behaviour, resulting in diverse spatial and temporal activity patterns across species. In this study, we analysed telemetry data from brown bears in Finland, Slovakia and Romania, to compare how human infrastructure influences their movement behaviour.

The Effect of Social Rank on Reproductive Traits Depends on Rank Metric: Evidence From a Group‐Living Carnivore

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
In animal societies, one's social rank determines access to resources like food, mates, and allies. Using longitudinal data on 481 spotted hyenas, we tested two common social rank metrics with different mechanistic assumptions to see whether resource access or social constraints could best explain different aspects of reproductive success.

Seasonal variations in ventricular repolarization and tachyarrhythmias in hibernating brown bears (Ursus arctos arctos)

open access: yesPhysiological Reports
In humans, hypothermia prolongs ventricular repolarization and associates with sustained ventricular tachyarrhythmias. In bears, body temperature drops during hibernation similar to moderate human hypothermia, yet they rarely face fatal outcomes during ...

Monitoring Brown Bears in Kazakhstan: A Pilot Study from the Altai Mountain Region

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
Here, we present results from the first camera trapping operation designed to detect brown bears in the Altai Mountain Region of Kazahstan and highlight some lessons learned from the pilot study. Our study was conducted at a relatively local scale but represents a first step towards understanding the presence of brown bears and other mammals in a ...

Alpine ungulates adjust diel activity to the natural return of wolves amid anthropogenic pressures

open access: yesEcography, Volume 2026, Issue 3, March 2026.
As wolves recolonise their historical range across Europe, ungulates face predation once more – but in landscapes profoundly altered by human activity. This shift raises crucial questions about their capacity to express adaptive antipredator behaviours.
