Dispersal of yearling pronghorns in western South Dakota

Article Abstract:

A research was conducted to determine timing, distance, and movements during dispersal and new range establishment by yearling pronghorns (Antilocapra americana) in western South Dakota. The study revealed that the habitat quality and pronghorn density partly spurs dispersal, and home range sizes and distance traveled during predispersal and dispersal movements by pronghorns increases with reduction in habitat patch size.

Article Abstract:

The effects of sarcoptic mange on the coyotes a Wind Cave National Park were studied. Results concluded that mange had significant impact on coyote population leading to reduction in survival rate and potentially density.
