In this fascinating biology of and guidebook to the bat species inhabiting the Rocky Mountain West, author Rick A. Adams exposes the true nature of bats and the roles these fascinating animals play in the natural history and ecology of the region.
 
In the twenty years since the original publication of Bats of the Rocky Mountain West, chiropterology (bat science) has exploded, significantly altering our understanding of the ecology, behavior, distribution, and conservation of one of the world's most enigmatic mammals. This notably updated second edition further brings to life the wonderful world of bats with beautiful illustrations and photography that grip the imagination and reveal the magnificent natural history of the only true flying mammal. In addition, thirty-two accounts of regional species with photographs, range maps, and echolocation sonograms report informative and thoroughly revised findings on bats now living in the Rocky Mountain West. Leave any preconceived notions behind and learn the real-life biology of bats, which eclipses the fabled tales of the crypt and macabre.
 

Among the few organizations with substantial experience in conserving and managing large ecosystems is The Nature Conservancy (TNC) -- the largest private, nonprofit conservation organization in the world dedicated to preserving natural areas, whose efforts have led to the protection of more than nine million acres of land across the United States and Canada.For more than fourteen years, W. William Weeks has worked in various capacities for The Nature Conservancy -- as state director, chief operating officer, and, currently, as vice president and director of The Center for Compatible Economic Development. During that time he has developed a deeply personal understanding of TNC's underlying philosophy and guiding methodology, and has come to appreciate the complex interaction between landscapes and people that characterize all conservation efforts. In Beyond the Ark, Weeks weaves together anecdotes, personal reflection, and fascinating detail from past and current Nature Conservancy projects to present a lively and inspiring introduction to issues of land conservation and management, and to The Nature Conservancy's approach to conservation.The author begins with a general introduction to conservation, to conservation planning, to the history and philosophy of The Nature Conservancy, and to the popular but often vaguely defined notion of ecosystem management. He then presents a detailed account of the conservation planning discipline that is at the heart of The Nature Conservancy's approach. Weeks offers in-depth description and analysis of the planning process that TNC goes through for each project -- a process designed to lead to a comprehensive understanding of the ecological system under consideration, threats to it and their causes, strategies for addressing those threats, and a means of measuring success. He ends with a consideration of the implications of the approach described, and presents his own thoughts on various aspects of the larger context in which conservation efforts must function.Beyond the Ark is an insightful and illuminating overview of conservation and management issues. Featuring a wealth of practical information gleaned from a wide range of real-life projects, it provides invaluable guidance to all those working to protect our endangered natural resources.

From the tufted puffin in the Pacific Northwest to the hook-billed hermit in the Brazilian rainforest, birds suffer from the effects of climate change in every corner of the globe. Scientists have found declines of up to 90 percent in some troubled bird populations and unprecedented reproductive failure in others. The most recent studies suggest dire prospects: 1,227 avian species are threatened with extinction and an additional 838 near-threatened species are urgent priorities for conservation action.

As much an indispensable guide as a timely call to action, Bird Watch is an illustrated tour of these endangered birds and their habitats. Encyclopedic in scope, this book features all 1,227 species on the International Union for Conservation of Nature (IUCN) Red List, thoroughly detailing the environmental pressures and conservation prescriptions that hold their futures in the balance. After introducing readers to the main threats to birds and regions at high risk, Bird Watch presents a visually stunning and scientifically accurate flight over the major bird habitats, including tropical forests; temperate and northern forests; deserts; mountains; grasslands; and Mediterranean, marine, freshwater, and oceanic islands. The volume concludes with an overview of bird species by region—categorized by family within each region, and a guide to the world’s best birding sites. Produced in cooperation with BirdLife International, Bird Watch is a celebration of the beauty and diversity of birds and their habitats—and a warning of the dangers they face around the world.

Brown bears are powerful symbols of wilderness, thriving in the vast, untamed ecosystems of Alaska’s remote national parks. Brown Bears in Alaska’s National Parks is a unique and thorough exploration of the conservation, ecology, and management of brown bears in these parks, including examinations of bear biology, human-bear interactions, population estimation methods, and the effects of climate change on bear populations. This lavishly illustrated volume offers fresh perspectives about the complex challenges that bears and humans face as they navigate coexistence in the evolving wilderness of Alaska.

Through park-specific chapters, the authors clearly present the current understanding of brown bear ecology across a wide range of ecosystems—from the sparse and frigid Gates of the Arctic, entirely above the Arctic Circle, to the bountiful coast of Katmai, where the marine and terrestrial systems converge. In Glacier Bay, bears roam newly exposed ecosystems shaped by retreating glaciers, while the interior landscapes of Lake Clark and Denali provide a mix of boreal forests, tundra, rivers, and towering mountains.

Brown bears—and the many species that share their habitats—face numerous challenges, with climate change among the greatest threats. The warming climate intensifies other pressures, such as industrial development, both within and around park boundaries. Management actions may also reduce native brown bear populations and, in turn, threaten healthy and naturally functioning ecosystems. The adaptability of brown bears, in concert with thoughtful and science-based management, is essential for the conservation of these majestic creatures and the wilderness landscapes on which they depend.

Written by the wildlife biologists and anthropologists who have dedicated their careers to studying brown (grizzly) bears and their relationship to people, Brown Bears in Alaska’s National Parks is a premier reference for bear enthusiasts, biologists, managers, and academics, as well as advocates for wild things and wild places.
