MINNEAPOLIS — Renowned Minnesota wolf researcher Dave Mech was in his early 20s and a graduate student at Purdue University when he arrived on Isle Royale in 1958 to study the predator-prey relationship between wolves and moose. Mech's three-year groundbreaking project detailed for the first time the killing efficiency of wolves and the vulnerability of moose on the 210-square-mile Lake Superior island.
Now in a compelling new book to be launched Tuesday titled "Wolf Island: Discovering the Secrets of a Mythic Animal," Mech, along with Twin Cities co-writer Greg Breining, chronicles Mech's life and times on Isle Royale — camping, hiking and observing from a single-engine airplane how wolves and moose interact in their constant struggle for survival.
