Sympatry Increases Predation Risk for an Endangered Ungulate

Ecology and Evolution, Volume 16, Issue 8, August 2026.
We characterized predation risk for Peninsular bighorn sheep and southern mule deer across their ranges to understand how topography, habitat, forage, and prey habitat suitability affect where pumas are likely to predate both species. The presence of the second ungulate species increased predation risk for both species but had the greatest effect on ...

Food or family? How gut microbes respond to diet and phylogeny in two deer species

Ecosphere
Vertebrate herbivores require symbiotic gastrointestinal (GI) microbes to extract energy and nutrients from fibrous and sometimes toxic plant diets.

Using maternal mule deer movements to estimate timing of parturition and assist fawn captures

Wildlife Society Bulletin, 2018
Movement patterns of maternal ungulates have been used to determine parturition dates and aid in locating fawns, which may be important for understanding reproductive rates (e.g., pregnancy and fetal), but such methods have not been validated for mule ...

Developing a macroecology for human‐altered ecosystems

Ecography, Volume 2026, Issue 8, August 2026.
Although anthropogenically‐induced ecological disruptions are fundamentally important in defining ecosystem properties, they are largely overlooked by macroecological theory. Anthropogenic disruptions and their effects are generally not comparable to one another, nor to disturbances that are part of natural disturbance regimes.

The Heritability of Migration Behaviors in a Wide‐Ranging Ungulate

Ecology and Evolution
Migration behavior is thought to be declining globally in the face of rapid human‐mediated environmental change. Although many species exhibit individual plasticity in their migratory behavior, not all species demonstrate the level of plasticity ...

Susceptibility of spring‐flowering garden plants to herbivory by mule deer

Wildlife Society Bulletin, 2018
Many people look forward to spring flowers, only to discover that mule deer (Odocoileus hemionus) have eaten the sprouting plants and flower buds. One potential method to prevent this problem is to grow unpalatable flowering plants in gardens where deer ...

Cattle and bison grazing decreases monarch egg and larval abundance in the Central United States

Ecosphere, Volume 17, Issue 8, August 2026.
Abstract Monarch butterflies have experienced massive population declines and have been proposed to be listed as threatened under the U.S. Endangered Species Act. Milkweeds (Asclepias spp.) are the sole host plant for monarch larvae, and milkweed abundance has dramatically declined in the past 25 years due to increased usage of herbicides and the ...

This is fine: Mule deer and elk do not substantially change their behavior in response to active wildfires

The Journal of Wildlife Management, Volume 90, Issue 6, August 2026.
During an outbreak of 7 wildfires in eastern Oregon, USA, we analyzed the home range and movement patterns of mule deer and elk before, during, and immediately after wildfires. Mule deer maintained high site fidelity during the wildfire but used their home range more uniformly and had higher daily displacement than deer unaffected by wildfire.

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.

Evaluating novel attachment methods for tracking devices on terrestrial mammals

The Journal of Wildlife Management, Volume 90, Issue 6, August 2026.
We deployed GNSS tracking devices on 2 endangered large terrestrial mammals, scimitar‐horned oryx and Przewalski's horses, using novel attachment methods. Tags achieved fix success rates and spatial accuracy that compare well with standard collars used on large mammals.
