Coyotes (Canis latrans) in the Rolling Plains region of Texas have experienced several factors in the last 40 years that may have possibly influenced population dynamics and feeding niche. The 3 most important changes were (a) the demand for coyote pelts during the 1970s, (b) a region-wide growth of the stocker cattle industry and (c) the increasing incidence of sarcoptic mange. The availability of stocker cattle carcasses may be providing a source of dependable food during a previously stressful period, thus inflating coyote survival and abundance superficially relative to traditional cow/calf ranching areas Sarcoptic mange has been present in Rolling Plains coyotes for about 10 years and appears to be depressing the abundance of coyotes in this region.
