On April 4th Mark Lesser is running a workshop at the Buffalo Bill Historical Center in Cody Wyoming. The workshop deals with populations at their range-margins, how range-margins have shifted in the past, and how they are currently changing. These topics are all discussed in the context of natural resource management. Speakers for the event include Steve Jackson, Simon Brewer and Mark Lesser from this lab, along with Dan Doak, Steve Gray (Jackson Lab Alumnus), Connie Millar and Eddie Bateson. The workshop has attracted over 50 people from the BLM, Forest Service, Park Service, and various other agencies.
