Distance, weather, and forage conditions drive timing of autumn migration in female mule deer

Movement Ecology
Background Seasonal migration is a behavioral strategy that animals evolved to exploit seasonally changing resources. Ungulates in northern temperate landscapes often seasonally migrate between low-elevation winter ranges and higher-elevation summer ...

Weather conditions associated with autumn migration by mule deer in Wyoming [PDF]

PeerJ, 2015
Maintaining ecological integrity necessitates a proactive approach of identifying and acquiring lands to conserve unfragmented landscapes, as well as evaluating existing mitigation strategies to increase connectivity in fragmented landscapes.

Merogonic stages of Theileria cervi in mule deer (Odocoileus hemionus) [PDF]

Journal of Veterinary Diagnostic Investigation, 2013
In February 2012, 12 farmed mule deer ( Odocoileus hemionus) were moved from a facility in southwestern Oklahoma to a facility in southeastern Oklahoma that housed 100 farmed white-tailed deer ( Odocoileus virginianus). Between the third and fifth weeks, 9 of the 12 mule deer had died, 4 of which were submitted for necropsy.

Pickin' up good vibrations: a systematic review of footfall detection and analysis in the realm of wildlife surveying

Wildlife Biology, EarlyView.
Exploration of new wildlife surveying methodologies that leverage advances in sensor technology and machine learning has led to tentative research into the application of seismology techniques. This, most commonly, involves the deployment of a footfall trap – a seismic sensor and data logger customised for wildlife footfall.

Spy in the sky: Application of thermal drones to assist with ground darting wildlife

Wildlife Society Bulletin
Telemetry studies allow scientists to track animal movements and study species ecology without direct visual observation. Fitting telemetry devices requires physical or chemical capture and restraint of animals.

Effects of underburning on habitat use of mule deer during migration

Wildlife Society Bulletin, 2019
Mule deer (Odocoileus hemionus hemionus) populations have been declining throughout their range and deteriorating habitat conditions are likely one cause of these declines. Reductions in food and cover availability along traditional routes may especially

Apex predators exploit advantageous snow conditions across hunting modes

Journal of Animal Ecology, EarlyView.
Advantageous snow conditions—in terms of snow depth and density—are among the most important features of the winter landscape for two apex predators, regardless of hunting strategy. In a warming climate, the knock‐on effects of a diminishing snowpack may reduce the hunting success of multiple large carnivore species.

Behavior, nutrition, and environment drive survival of a large herbivore in the face of extreme winter conditions

Ecosphere, 2023
For many species, behavioral modification is an effective strategy to mitigate negative effects of harsh and unpredictable environmental conditions. When behavioral modifications are not sufficient to mitigate extreme environmental conditions, intrinsic ...

Food Subsidies Reduce Livestock Depredations by a Recovering Carnivore

Animal Conservation, EarlyView.
Diversionary feeding—providing food caches to divert predators away from preying on livestock—is a strategy to reduce depredations by Mexican gray wolves but has not been evaluated for its effectiveness. We used data from the Mexican wolf recovery program from 2014‐2021 to evaluate whether diversionary feeding reduced livestock depredations by wolf ...
