The interactions between apex predators and their prey are some of the most awesome and meaningful in nature - displays of strength, endurance, and a deep coevolutionary history. And there is perhaps no apex predator more impressive and important in its hunting - or more infamous, more misjudged - than the wolf. Because of wolves' habitat, speed, and general success at evading humans, researchers have faced great obstacles in studying their natural hunting behaviors. The first book to focus explicitly on wolf hunting of wild prey, Wolves on the Hunt seeks to remedy these gaps in our knowledge and understanding. Combining behavioral data, thousands of hours of original field observations, research in the literature, a wealth of illustrations, and - in the e-book edition and online - video segments, the authors create a compelling and complex picture of these hunters. The wolf is indeed an adept killer, able to take down prey much larger than itself. While adapted to hunt primarily hoofed animals, a wolf - or especially a pack of wolves - can kill individuals of just about any species.But even as wolves help drive the underlying rhythms of the ecosystems they inhabit, their evolutionary prowess comes at a cost: wolves spend one third of their time hunting - the most time-consuming of all wolf activities - and success at the hunt only comes through traveling long distances, persisting in the face of regular failure, detecting and taking advantage of deficiencies in the physical condition of individual prey, and through ceaseless trial and error, all while risking injury or death. By describing and analyzing the behaviors wolves use to hunt and kill various wild prey - including deer, moose, caribou, elk, Dall sheep, mountain goats, bison, muskoxen, arctic hares, beavers, and others - Wolves on the Hunt provides a revelatory portrait of one of nature's greatest hunters.

In a fascinating story of discovery and science, we meet a remote population of wolves unafraid of humans.  For parts of twenty-four summers, wolf biologist L. David Mech lived with a group of wolves on Ellesmere Island, some six hundred miles from the North Pole. Elsewhere, most wolves flee from even the scent of humans, but these animals, evolving relatively free from human persecution, are unafraid. Having already spent twenty-eight years studying other populations of wolves more remotely by aircraft, snow-tracking, live-trapping, and radio-tracking, Mech was primed to join their activities up close and record their interactions with each other. This book tells the remarkable story of what Mech—and the researchers who followed him—have learned while living among the wolves.  The Ellesmere wolves were so unconcerned with Mech’s presence that they allowed him to camp near their den and to sit on his all-terrain vehicle as he observed them, watching packs as large as seven adults and six pups go about their normal activities. In these extraordinarily close quarters, a pup untying his bootlace or an adult sniffing his gloved hand was just part of daily life. Mech accompanied the wolves on their travels and watched as they hunted muskoxen and arctic hares. By achieving the same kind of intimacy with his wild hosts’ every action that we might experience living with domesticated dogs, Mech gained new insights into common but rarely studied behaviors like pup feeding, food caching, howling, and scent-marking. After Mech’s time at Ellesmere ended, his coauthors and fellow wolf researchers Morgan Anderson and H. Dean Cluff spent parts of four summers studying the wolves via radio collars, further illuminating the creatures’ movements and ecology. This book synthesizes their findings, offering both a compelling scientific overview of the animals’ behavior—from hunting to living in packs to rearing pups—and a tale of adventure and survival in the Arctic.

Throughout the continents of Eurasia and North American primitive man evolved in association with wolves. Wolves competed with him as a hunter, and raided his flocks and herds. Inevitably, folklore became rich in tales of this powerful, resourceful creature.Europeans reached North American with their attitudes already formed. The wilderness pressed in upon their tiny settlements in constant threat and all energies were devoted to destroying it and turning its inexhaustible resources to use. Over vast areas of the continent the wolf went down with the wilderness before the unprecedented effectiveness of our technological attack on the ecology of a continent. Today, however, there is a great tide of concern over the consequences of our assault on the wild lands and wild creatures on the continent, and more and more biologists are devoting their knowledge and energy to searching studies of our land and its native biota.The wolf has been the subject of detailed study by a number of ecologists on this continent who make use of all the research devices now available. Much of our knowledge is very recent, is increasing rapidly, and has resulted from the work of a mere handful of keen, resourceful, and courageous students of wolf biology. This, the first book to attempt a complete account of the biology of the wolf, draws from years of field research and upon the rich literature from two continents. --From the foreword by Ian McTaggert Cowan

The definitive study of this important wolf community-now in paperback.For more than nine years the wolves in Alaska’s Denali National Park were the subject of intense research by a group of renowned scientists led by L. David Mech. The result of their work is the most comprehensive study of a population of wolves and their prey ever available. This accessible, fascinating, and extensively illustrated book will appeal to researchers, general readers, and wolf enthusiasts across the world.

The world’s leading wolf expert describes the first years of a major study that transformed our understanding of one of nature’s most iconic creaturesIn the late 1940s, a small pack of wolves crossed the ice of Lake Superior to the island wilderness of Isle Royale, creating a perfect “laboratory” for a long-term study of predators and prey. As the wolves hunted and killed the island’s moose, a young graduate student named Dave Mech began research that would unlock the mystery of one of nature’s most revered (and reviled) animals-and eventually became an internationally renowned and respected wolf expert. This is the story of those early years.Wolf Island recounts three extraordinary summers and winters Mech spent on the isolated outpost of Isle Royale National Park, tracking and observing wolves and moose on foot and by airplane-and upending the common misperception of wolves as destructive killers of insatiable appetite. Mech sets the scene with one of his most thrilling encounters: witnessing an aerial view of a spectacular hunt, then venturing by snowshoe (against the pilot’s warning) to photograph the pack of hungry wolves at their kill. Wolf Island  owes as much to the spirit of adventure as to the impetus of scientific curiosity. Written with science and outdoor writer Greg Breining, who recorded hours of interviews with Mech and had access to his journals and field notes from those years, the book captures the immediacy of scientific fieldwork in all its triumphs and frustrations. It takes us back to the beginning of a classic environmental study that continues today, spanning nearly sixty years-research and experiences that would transform one of the most despised creatures on Earth into an icon of wilderness and ecological health.

This book outlines how to reorganize the U.S. Army into a fully 2 and 3-Dimensional maneuver capable, ground force with terrain-agile, armored fighting vehicles sized to rapidly deploy by fixed-wing and rotary-wing aircraft to the scene of world conflicts and strike at the heart of freedom‚s enemies. The plan to build the Army into Air-Mech-Strike Forces, exploiting emerging information-age technologies, as well as America‚s supremacy in aircraft and helicopter delivery systems---at the lowest cost to the taxpayers, is described in detail. These Army warfighting organizations, using existing and some newly purchased equipment, will shape the battlefield to America‚s advantage, preserving the peace before it is lost; if not, then winning fights that must be fought quickly. The dangerous world we live in moves by the speed of the AIR, and the 21st Century U.S. Army 2D/3D combat team will dominate this medium by Air-Mech-Strike!
