“It was logical to pick up Schenkel’s work,” Mech said, which laid out the terms “lead wolf” and “bitch wolf,” the antecedents of “alpha male” and “alpha female.” Schenkel wrote, “Every mature wolf has an ever ready ‘expansion power,’ a tendency to widen, not his personal territory, but rather, his own social behaviour freedom.” He added, “The maintenance of a not-quite-classless status requires constant self-assertion.” Schenkel also believed that wolves needed an outlet for aggressive energy, typically “released at the weakest individuals of the society.” The main study at the time was by Rudolph Schenkel. Mech had relied on research done on captive wolves. What bothers him most is the section he wrote on pack order. The book remained in print, even though Mech asked many times that it no longer be published. “That was what we knew at the time, but I’d say we’ve learned more about wolves since that book’s publication than we had in all of previous history,” he told me. In time, however, Mech became less than pleased with the book’s ongoing success. The book became a best-seller and a foundational text, one that was read both by scientists and by laypeople. In 1970, Mech published “The Wolf: The Ecology and Behavior of an Endangered Species.” The book assembled an enormous amount of research on wolves, covering aspects including wolf habits, wolf society, and the relations of the wolf to prey, to non-prey, to disease, and, of course, to humans. Scientists flying overhead in winter could see their footprints in the snow. The island was only two hundred and ten square miles, and the wolves tended to follow waterways and shorelines, which made it easier to keep track of them. A decade later, the Park Service instituted protections against wolf-eradication efforts there.) Moose had been known to have come to Isle Royale in the early twentieth century the wolves had first arrived in the late nineteen-forties, having crossed an ice bridge from Canada. Murie had been asked by the National Park Service to look at the relationship between timber wolves and Dall sheep in the area Murie, after walking thousands of miles over three summers, concluded that the various fauna populations-including caribou and grizzly bears-were keeping one another in balance. McKinley,” a monograph published by Adolph Murie, in 1944.
(It was inspired in part by “ The Wolves of Mt. The Isle Royale study, which was started by Durward Allen, a celebrated biologist, was one of the earliest major studies of wolves in their natural setting. “They could have had something more to eat!” The wolf, as he later described it in print, is “one of the wildest and shyest of all the animals in the northern wilderness.” And the standard things from storybooks.” Upon spotting him, the wolves ran off, leaving behind the moose carcass. We knew that they lived in packs, that they preyed on large animals, and that they howled. “Long ago, when I started, we knew very little about wolves in the wild. He didn’t know how the wolves would react when they saw him. “I remember arriving to the edge of this clearing, and there were these fifteen wolves feeding on this moose,” he said. He had the pilot drop him off some distance away, and snowshoed in. “I wanted to see how old this moose was, and to see if it was ill,” Mech told me recently. More than nine times out of ten, he had witnessed the wolves’ prey escape.
From above, he saw a wolf pack capture and kill a moose. In 1958, as part of a research project on wolves, David Mech, a graduate student in wildlife ecology at Purdue, was flying over Isle Royale National Park, on Lake Superior.
