Thermal imagery of wolves howling near Yellowstone National Park. This technology is helping USGS scientists understand the impacts of disease on the health of wolves. The thermal imagery helps by measuring temperature loss from the mange patches (red) and comparing this with temperature loss from natural fur (blues and greens). Image courtesy of Paul Cross, USGS.
