Exploring durophagy among modern gray wolves from the Greater Yellowstone Ecosystem with dental microwear texture analysis
Abstract Gray wolf ( Canis lupus ) dietary behavior can be highly variable; prey species for wolves span a range of ungulates to the consumption of smaller animals. While prey species for wolves are well documented, carcass utilization within and between wolf populations is less understood. This pap...
