Popis:	Knowledge of fundamental biological characteristics, such as food habits, is essential for conserving wildlife, especially as species distributions shift in response to climate change. We captured wolverines (Gulo gulo) in Greater Yellowstone, one of the southernmost points of the species distribution, where we identified wolverine food items in the field (n = 91) and collected wolverine scats (n = 96) while snow tracking, visiting den and rendezvous sites, and examining concentrated locations from very high frequency (VHF) telemetry and global positioning system (GPS) collars. Similar to other areas of their distribution, wolverines in Greater Yellowstone appeared to focus on scavenging ungulates during winter (χ2 = 20.1, df = 1, P < 0.0001) and preying upon rodents, neonatal ungulates, and other small prey during summer (χ 2 = 2.94, df = 1, P = 0.08). However, our results showed a focus on food species not found across much of the wolverine's circumboreal range, e.g., elk (Cervus ...
