Harvest of Fish and Wildlife: New Paradigms for Sustainable Management unites experts in wildlife and fishery sciences for an interdisciplinary overview of harvest management. This book presents unique insights for embracing the complete social-ecological system to ensure a sustainable future. It educates users on evolutionary and population dynamics; social and political influences; hunter and angler behavior; decision processes; impacts of regulations; and stakeholder involvement. Features: Written by twenty-four teams of leading scientists and managers. Promotes transparent justification for fishing and hunting regulations. Provides examples for integrating decision making into management. Emphasizes creativity in management by integrating art and science. This book appeals to population biologists, evolutionary biologists and social scientists. It is a key resource for on-the-ground managers and research scientists developing harvesting applications. As the book’s contributors explain: “Making decisions that are robust to uncertainty...is a paradigm shift with a lot of potential to improve outcomes for fish and wildlife populations.” –Andrew Tyre and Brigitte Tenhumberg “Temporal shifts in system states...must somehow be anticipated and dealt with to derive harvest policies that remain optimal in the long term.” –Michael Conroy “Proactive, effective management of sportspersons...will be essential in the new paradigm of harvest management.” –Matthew Gruntorad and Christopher Chizinski

Published in 1955 by the University of Oklahoma Press, this is the classic study of the extinction of the passenger pigeon. The passenger pigeon, once probably the most numerous bird on the planet, made its home in the billion or so acres of primary forest that once covered North America east of the Rocky Mountains. Their flocks, a mile wide and up to 300 miles long, were so dense that they darkened the sky for hours and days as the flock passed overhead. Population estimates from the 19th century ranged from 1 billion to close to 4 billion birds. Total populations may have reached 5 billion birds and comprised up to 40% of the total number of birds in North America. This may be the only species for which the exact time of extinction is known. No appreciable decline in the numbers was noted until the late 1870s but, thereafter, their destruction took only twenty-five years. The immense roosting and nesting colonies invited over-hunting. Tens of thousands of individuals were harvested daily from nesting colonies, and shipped to markets in the east. Modern technology hastened the demise of the passenger pigeon. With the coming of the telegraph, the locations of flocks could be ascertained, and the birds relentlessly pursued. The last bird died in 1914 at the Cincinnati Zoological Garden before any competent ornithologists could write an account of the species. A. W. Schorger reconstructed the life history of the passenger pigeon. Through painstaking research, he examined every aspect of the species -- behavioral characteristics, feeding methods, traveling and roosting habits, nesting - and the various stages of the species encounter with man, from utilization by the Native American to extinction at the hands of white settlers.

Amphibians and reptiles represent an essential and interesting component of Wisconsin's wildlife. Eighteen species of amphibian and thirty-six species of reptile occupy landscapes across the state. They live in aquatic habitats that range from small streams to large lakes, and from open prairies to mature forests on land. These species are vital members of the biological communities in which they occur, acting as important predators, prey, and competitors, while also providing a wide variety of additional ecological functions. However, many amphibians and reptiles have experienced drastic population declines and even local extinctions in Wisconsin due to habitat loss and degradation, overharvesting, the introduction of invasive species, pollution, and other factors. This comprehensive volume, by an expert team of editors and contributors, consolidates the current state of scientific knowledge, aims to expand public knowledge and appreciation of Wisconsin's natural legacy, and brings out the herpetologist in all of us. This long-awaited, state-of-the-field synthesis also includes hundreds of color photographs and illustrations, state-level and North American range maps, dichotomous keys, and research and conservation anecdotes that will entertain and inform even the most dedicated nature lover. Amphibians and Reptiles of Wisconsin is set to become a lasting resource and armchair companion for anyone in the Midwest interested in the state's natural history and amphibian and reptile fauna.

It was 1978, and there had been no resident timber wolves in Wisconsin for twenty years. Still, packs were active in neighboring Minnesota, and there was the occasional rumor from Wisconsin's northwestern counties of wolf sign or sightings. Had wolves returned on their own to Wisconsin? Richard Thiel, then a college student with a passion for wolves, was determined to find out. Thus begins Keepers of the Wolves, Thiel's tale of his ten years at the center of efforts to track and protect the recovery of wolves in Northern Wisconsin. From his early efforts as a student enthusiast to his departure in 1989 from the post of wolf biologist for the Department of Natural Resources, Thiel conveys the wonder, frustrations, humor, and everyday hard work of field biologists, as well as the politics and public relations pitfalls that so often accompany their profession. We share in the excitement as Thiel and his colleagues find wolf tracks in the snow, howl in the forest night and are answered back, learn to safely trap wolves to attach radio collars, and track the packs' ranges by air from a cramped Piper Cub. We follow the stories of individual wolves and their packs as pups are born and die, wolves are shot by accident and by intent, ravages of canine parvovirus and hard winters take their toll, and young adults move on to new ranges. Believing he had left his beloved wolves behind, Thiel takes a new job as an environmental educator in central Wisconsin, but soon wolves follow. By 1999, there were an estimated 200 timber wolves in 54 packs in Wisconsin. This is a sequel to Dick Thiel's 1994 book, The Timber Wolf in Wisconsin: The Death and Life of a Majestic Predator. That book traced the wolf's history in Wisconsin, its near extinction, and the initial efforts to reestablish it in our state. Thiel's new book looks at how successful that program has been.
