Role of badger setts in life of other carnivores

Studia Ecologiae et Bioethicae, 2015
A study of interspecific interactions of European (Meles meles) and Asian (M. leucurus) badgers with other carnivores at badger setts was carried out in Darwin Reserve (European part  of Russia) and in Ussuriisk Reserve (Russian Far East) in 2006-2011 ...

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 ...

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.

Variation in energetic balance among free-ranging polar bears during the spring mating and foraging season

Arctic Science
Large carnivores are capable of consuming substantial biomasses that can significantly alter their body mass and condition over short periods. Here we examine the intra-seasonal variation of polar bear (Ursus maritimus Phipps, 1774) body mass, energy ...

Landscape Structure and Species Interactions Drive the Distribution of Salmon Carcasses in Coastal Watersheds

Frontiers in Ecology and Evolution, 2019
The disproportionate effects of some species can drive ecosystem processes and shape communities. This study investigates how distributions of spawning Pacific salmon within streams, salmon consumers, and the surrounding landscape mediate the ...

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 ...

Using tri-axial accelerometers to identify wild polar bear behaviors

Endangered Species Research, 2017
Tri-axial accelerometers have been used to remotely identify the behaviors of a wide range of taxa. Assigning behaviors to accelerometer data often involves the use of captive animals or surrogate species, as their accelerometer signatures are generally ...

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.

Inbreeding and Demographic History of Caribou (Rangifer tarandus) in Western Canada Inferred From Genome‐Wide SNP Data

Evolutionary Applications, Volume 19, Issue 8, August 2026.
ABSTRACT Assessing genetic diversity is essential for conserving endangered populations, yet comprehensive genomic evaluations remain limited for many declining species. Here, we investigated inbreeding levels and effective population sizes (Ne) of caribou (Rangifer tarandus) in western Canada, where populations have experienced pronounced declines ...

Conservation of Threatened Canada-USA Trans-border Grizzly Bears Linked to Comprehensive Conflict Reduction

Human-Wildlife Interactions, 2018
Mortality resulting from human–wildlife conflicts affects wildlife populations globally. Since 2004, we have been researching conservation issues and implementing a comprehensive program to reduce human–bear conflicts (Ursus spp.; HBC) for 3 small ...
