Comparative foraging ecology of lynx and coyotes in three Gulf of Alaska national parks

Ecosphere, Volume 17, Issue 8, August 2026.
Abstract Consumers exhibit varying degrees of dietary specialization, with foraging strategies shaped by both evolutionary history and local food availability. In boreal systems, Canada lynx are considered snowshoe hare specialists, whereas coyotes are classically generalist foragers capable of exploiting diverse resources.

Shared foraging behaviors between hyenas and hominins in the Middle Paleolithic Levant: New evidence from Geula Cave, Israel

Journal of Quaternary Science, Volume 41, Issue 6, Page 896-914, August 2026.
ABSTRACT While competition with large carnivores is likely to have shaped Middle Paleolithic hominins' subsistence behavior, palimpsested human and carnivore accumulations render the signal challenging to isolate. This study presents a detailed zooarchaeological and taphonomic analysis of a non‐anthropogenic faunal assemblage from a MIS 5 (~130–80 ka ...

Remodeling of skeletal muscle myosin metabolic states in hibernating mammals

eLife
Hibernation is a period of metabolic suppression utilized by many small and large mammal species to survive during winter periods. As the underlying cellular and molecular mechanisms remain incompletely understood, our study aimed to determine whether ...

Cougar density on the Oregon Coast: Using dead recovery modeling in an open population

The Journal of Wildlife Management, Volume 90, Issue 6, August 2026.
The primary objective of this study was to determine cougar density in western Oregon. Our results demonstrate that integrating DNA collected via bio‐darting, mandatory hunter‐harvest check‐ins, and GPS collar data into the OPCR2 is a reliable method for estimating cougar densities in densely forested coastal systems.

Familiarity and aggression shape long‐term associations and mortality risk in a solitary ungulate

Oikos, Volume 2026, Issue 8, August 2026.
Periodic social interactions are important to animal fitness, even in solitary species. For solitary species, these interactions can be unexpected and shaped by previous encounters. Despite being aggressive and largely solitary, black rhinoceroses Diceros bicornis are commonly seen in groups, suggesting they may engage in more social behaviours than ...

When wolves aren't enough: revisiting trophic cascades in northern Wisconsin

Oikos, Volume 2026, Issue 8, August 2026.
Elimination of top predators has allowed large herbivores to flourish in many terrestrial ecosystems, transforming food webs and ecosystem functions. Restoration of large predator communities is hoped to reverse negative effects of this trophic downgrading, but evidence for such effects is elusive.

Using Ongoing Wildlife Surveillance Programs to Monitor Antibiotic Resistant Bacteria in the Environment

Environmental Microbiology Reports, Volume 18, Issue 4, August 2026.
Screening of ESBL‐, pAmpC‐ and carbapenemase‐producing Escherichia coli among Swedish wildlife demonstrated a low occurrence of antibiotic resistance in wild animals. Only two ESBL/pAmpC‐producers were detected in red foxes originating from highly populated areas.

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

Ecology 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 impacts of different visitor management strategies on wildlife activity in a popular desert nature reserve

Conservation Science and Practice, Volume 8, Issue 8, August 2026.
Abstract Water sources in desert ecosystems are critical for wildlife survival, but they may also attract thousands of visitors, creating potential conflicts between humans and wildlife. Effective management strategies are essential to support human‐wildlife coexistence in these fragile arid environments, allowing for sustainable tourism while ...
