Course Hero is not sponsored or endorsed by any college or university. Over the last decade, many new tracking studies have been conducted on migratory herds, and analytical methods have been developed that allow for population-level corridors and stopovers to be mapped and prioritized. In 2019, the team completed analyses necessary to map corridors, stopovers, and winter ranges in Arizona, Idaho, Nevada, Utah, and Wyoming. population growth of the kaibab deer and it reflects how human interactions affect the Kaibab Why do you suppose the population of deer declined in 1925, although the eliminated of predators occurred?
