Compounding effects of cattle, wild ungulates, and beaver impede riparian restoration

Ecosphere, Volume 17, Issue 9, September 2026.
Abstract Planting native woody vegetation is a common restoration practice to increase stream shade, an important salmonid habitat recovery strategy in the interior Pacific Northwest (PNW, USA). Herbivory by domestic livestock and wild mammals, a ubiquitous disturbance in PNW riparian zones, is a common barrier to survival and growth of plantings ...

Habitat characteristics along spring migration routes of elk, mule deer, and pronghorn in the southern San Juan Mountains

The Journal of Wildlife Management, Volume 90, Issue 7, September 2026.
We evaluated habitat characteristics of spring migration routes and stopover sites for adult female elk (Cervus canadensis), mule deer (Odocoileus hemionus), and pronghorn (Antilocapra americana) in the San Juan Mountains (2021–2022) and found species‐specific differences in vegetation structure, terrain, and proximity to land cover types relative to ...

Effects of off‐highway vehicle activity on Arizona wildlife: a systematic literature review

The Journal of Wildlife Management, Volume 90, Issue 7, September 2026.
The published literature indicates that off‐highway vehicles (OHVs) predominantly negatively affect native Arizona amphibians, mammals, and reptiles, while effects of OHVs on native Arizona birds are mostly unknown or neutral. Abstract Off‐highway vehicle (OHV) recreation has dramatically increased in Arizona, USA, prompting concerns about potential ...

Determining Timing of Births and Habitat Selection to Identify Lambing Period Habitat for Bighorn Sheep

Frontiers in Ecology and Evolution, 2020
Timing of births in ungulates is influenced by ecological factors, and differences in seasonality of births have evolutionary implications for these mammals.

Feast or famine: How food deserts, wealth and greenspace correlate with coyote diets in Seattle, Washington

People and Nature, Volume 8, Issue 9, Page 3051-3065, September 2026.
Abstract Urban environments create unique challenges for wildlife, where dietary habits may reflect both ecological heterogeneity and societal disparities. In this study, we explored how social factors such as household income and human population density, and ecological factors such as tree canopy correlate with coyote (Canis latrans) diets in Seattle,

Survival of Bighorn Sheep (Ovis canadensis) Commingled with Domestic Sheep (Ovis aries) in the Absence of Mycoplasma ovipneumoniae [PDF]

Journal of Wildlife Diseases, 2012
To test the hypothesis that Mycoplasma ovipneumoniae is an important agent of the bighorn sheep (Ovis canadensis) pneumonia that has previously inevitably followed experimental commingling with domestic sheep (Ovis aries), we commingled M. ovipneumoniae-free domestic and bighorn sheep (n=4 each).

A high‐altitude thermal infrared method for estimating moose abundance and demography in Rocky Mountain National Park, USA

Wildlife Biology, Volume 2026, Issue 5, September 2026.
Resource managers require accurate estimates of large herbivore abundance and demography to maintain ecological integrity. Common methods to count these species, including observations from low altitude helicopter flights, may conflict with other protected area management objectives and struggle to produce precise estimates for more cryptic species. To

Reliability of tooth cementum rings to age bighorn sheep: a blind test

California Fish and Wildlife Journal
Tooth cementum rings often have been considered the most reliable method for aging larger mammals. Tests of this approach have used samples of known ages, but to ensure objectivity this needs to be carried out as truly blind tests.

Cross-species characterisation of polymorphic microsatellite loci in the giant otter (Pteronura brasiliensis). [PDF]

, 2009
Nineteen microsatellite loci developed for the Eurasian otter (Lutra lutra) and 15 loci developed for the North American river otter (Lontra canadensis) were tested for ease of amplification and degree of polymorphism on a set of 20 giant otter ...
