サマリー
Black-tailed prairie dogs are native to the Great Plains, but Sylvatic plague (Yersinia pestis) is not. This disease was first introduced to North America in the early 1900s and only reached many regions of the Great Plains within the past 20–30 years. This disease can wipe out 95-99% of prairie dogs in a landscape. In some landscapes, these population "busts" can be followed by rapid growth, leading to population "booms" that intensify conflicts with livestock. This destabilized system has negative effects on both livestock and wildlife, and understanding either how to stabilize these dynamics, or at least mitigate their effects, is a major priority for managers. In this episode, Meghan Robinson speaks with Dr. Courtney Duchardt, an assistant professor at Oklahoma State University, who is studying these population cycles to evaluate their effects on associated wildlife, and explore management strategies to address these issues.
