Introducing Dr.Walter Piper, Professor of Biology at Chapman University in Orange, California. He has studied the loon population on a hub of lakes in northern Wisconsin since 1993. Some models suggest the habitat is moving northward-and that loons will be a rarity in Wisconsin by 2080. Will agricultural crops follow that trend? Have they already? Anecdotal evidence says yes, but that's not good enough. My plan is to follow Dr. Piper and learn about his work and see if an analogy can be drawn to agricultural cropping systems evolving northward.
