Southeast Alaska's remaining virgin forests have few insect pests. The black-headed budworm and the hemlock sawfly, both western hemlock defoliators, are the most important species. They kill some trees, kill tops in others, and cause growth loss, but stands survive their attacks. Extensive conversion of virgin stands to second growth may result in an increase in pest problems as it has in similar areas such as coastal British Columbia. ??Widespread use of insecticides to control major outbreaks is not practical because of risk of contaminating salmon-spawning and trout-rearing streams; but insecticide use may be justified in local, high value areas. Weather, diseases, and parasites control outbreaks naturally. Damage-prone stands should be identified and harvested before insect attack or salvage-logged following outbreaks. Ideally, second-growth stands should be managed for resistance to insect pests.

Dr. Walker and Dr. Corbet make a signal contribution in gathering together all available information on the dragonflies of Canada and Alaska. The order as a whole and the zygoptera are covered. The treatment is not confined to taxonomy and geographical distribution, but includes data on habitats, seasons of adult life, and brief notes on habits when these are available.

“Unlike the standard nature guides that explain how to recognize common animals, Nature stresses the web of interrelationships that link the regional flora and fauna. This affectionate examination of some of North America’s most spectacular surviving old-growth forests will delight backpackers and armchair naturalists.” —Los Angeles Times Book Review Everything you ever wanted to know about the flora and fauna of Southeast Alaska is contained in the third edition of this lively field guide to the natural world, from bears to banana slugs, mountains to murrelets. The authors, who are both Alaskan residents and biologists, combine scientific research with personal experiences to make a definitive field guide for residents of or visitors to Southeast Alaska. The unique features of the book include: In-depth information about how wildlife coexists with the environment Detailed discussions of mammals, birds, fish, invertebrates, fungi, and plants Detailed map of wilderness areas in Southeast Alaska More than 200 black-and-white illustrations A bibliography, list of common and scientific names, and an index New to this edition: More than 100 new illustrations, many never before published, as well as new maps and photos Major expansion of sections on geology, old-growth forests, marine mammals, and amphibians Fifty-two new sidebars—written in the first person to give the text a more personal touch—that describe recent findings or experiences. Sweeping updates and elaborations to chapter narratives—often thanks to technology unknown in 1992. In-depth guide to Southeast Alaska’s flora and fauna; more than an identification manual, Nature explores how the species and habitats encountered in the woods and waters of Southeast Alaska fit into the bigger picture.

Alaska's great size is mirrored by the large number and diversity of its freshwater ecosystems. This volume reviews and synthesizes research on a variety of Alaskan freshwaters including lakes, rivers and wetlands. The vast range of Alaskan habitats ensures that the chapters in this book will provide valuable information for readers interested in freshwaters, particularly nutrient dynamics, biotic adaptations, recovery mechanisms of aquatic biota, stream succession and the management of human-induced changes in aquatic habitats.

This book recounts the habits of many interesting and unusual exceptions to the rule that insects are typically terrestrial forms of life. It examines the different ways that groups of species have developed modes of existence in or on the surface of water, and gives reasons why the gross morphology of insects is not favorable for life in or near bodies of water, such as wings that fail to function after coming into contact with water, rendering them useless.
