These collared deer left their Red Desert haunts in the spring and shocked everyone by traveling 150 miles northwest to near Jackson Hole. Since then, they have been developing, adapting, and applying various technologies such as step selection function, resistance path and connectivity modeling, as well as the Brownian Bridge Movement Modeling used in most of the Wyoming work. There are some arguments that this subspecies is not actually different from Rocky Mountain mule deer, although many biologists also believe it is simply a southern form of this subspecies. . Being able to get our hands on coordinates of an animal every 12 hours, 2 hours, or even more frequently has completely revolutionized the type of information we can glean and the research questions we can ask.
