Denning chronology in an Arctic brown bear population

Wildlife Biology, EarlyView.
Denning is a critical behavioral adaptation for brown bears Ursus arctos to cope with winter, a period of extended resource scarcity. Bears reduce their body temperature, heart rate, and metabolism during this time to minimize energy expenditures. The Arctic has among the most pronounced and longest period of resource scarcity. Thus, we predicted bears

Evaluating patterns of plant phenological progression and pronghorn movement behaviors across diverse landscapes Évaluation des modèles de progression phénologique des plantes et des comportements de mouvement des antilopes d'Amérique dans divers paysages

Wildlife Monographs, EarlyView.
We found variable spatial and temporal patterns and predictability of plant phenological progression across 8 pronghorn ranges in Montana. We sampled potential exposure to phenology values for migrants and residents along spring movement paths and summer ranges and found that within herds and years the resident and migrant movement strategies conferred

Documenting den characteristics of bears and wolves in the Greater Yellowstone Ecosystem using LIDAR technology

Wildlife Society Bulletin, EarlyView.
Previous studies have documented den site characteristics through physical measurements recorded by researchers in the field. Using the light detection and ranging (LiDAR) sensor onboard an Apple iPad Pro, we scanned the interior of black and grizzly bear dens (n = 9) located in the Greater Yellowstone Ecosystem (GYE) to generate point clouds of den ...

Use of Apple Airtag to track urban wildlife: Proof of concept with Harris's hawks

Wildlife Society Bulletin, EarlyView.
Abstract Accurate tracking of the movement of wildlife is important for understanding the behavior, spatial use, and resource selection of a species. While traditional methods like Very High Frequency (VHF) transmitters have been widely used, newer technologies, such as GPS data loggers and Global System for Mobile Communications (GSM) transmitters ...
