Mange in Wolves
Researchers and their partners place thermal remote cameras near deer and elk carcasses in Yellowstone National Park to capture images of wolves with mange feeding in the wild. Red-colored blotches in the thermal images reveal areas of hair loss from which wolves with mange lose heat.
During winter, wolves infected with mange can suffer a substantial amount of heat loss compared to those without the disease, according to a study by the U.S. Geological Survey and its partners.
Using a remotely triggered thermal camera to capture vivid and colorful images, scientists gathered body temperature data from mange-infected gray wolves in Yellowstone National Park and compared that to a sample group of healthy captive wolves with shaved patches of fur to simulate mange-induced hair loss. Using these data, scientists were able to quantify the level of heat loss, or energetic costs, during the winter months. Having said all of that, and after viewing over 20 elk found dead in Wyoming due to what was described as sport kills by wolves, it's hard to be sympathetic.
