Psychedelically colored wolves depicted by thermal imaging will shed light on how mange affects the survival, reproduction and social behavior of wolves in Yellowstone National Park. About a quarter of the wolf packs in the park are afflicted with sarcoptic mange, a highly contagious canine skin disease caused by mites that burrow into the skin causing infections, hair loss, severe irritation and an insatiable desire to scratch. The resulting hair loss and depressed vigor of the wolves leaves them vulnerable to hypothermia, malnutrition and dehydration, which can eventually lead to death, said Paul Cross, a U.S. Geological Survey disease ecologist, who leads the project along with Doug Smith of Yellowstone National Park.
