This open access book reviews the importance of ecological functioning within rangelands considering the complex inter-relationships of production agriculture, ecosystem services, biodiversity, and wildlife habitat. More than half of all lands worldwide, and up to 70% of the western USA, are classified as rangelands—uncultivated lands that often support grazing by domestic livestock. The rangelands of North America provide a vast array of goods and services, including significant economic benefit to local communities, while providing critical habitat for hundreds of species of fish and wildlife. This book provides compendium of recent data and synthesis from more than 100 experts in wildlife and rangeland ecology in Western North America. It provides a current and in-depth synthesis of knowledge related to wildlife ecology in rangeland ecosystems, and the tools used to manage them, to serve current and future wildlife biologists and rangeland managers in the working landscapes of the West. The book also identifies information gaps and serves as a jumping-off point for future research of wildlife in rangeland ecosystems. While the content focuses on wildlife ecology and management in rangelands of Western North America, the material has important implications for rangeland ecosystems worldwide.

Until now there has been no single, comprehensive resource on the status of North America's most threatened birds and what people can do to help protect them. Birder's Conservation Handbook is the only book of its kind, written specifically to help birders and researchers understand the threats while providing actions to protect birds and their habitats. Jeffrey Wells has distilled vast amounts of essential information into a single easy-to-use volume-required reading for anyone who loves birds and wants to ensure they are protected. At-a-glance species accounts cover in detail North America's one hundred most at-risk birds; each account is beautifully illustrated by today's top bird artists. The text includes status, distribution, ecology, threats, conservation actions and needs, and references. A distribution map accompanies each entry. Chapters discuss birds as indicators of environmental health, the state of North American bird populations, major conservation issues, and initiatives now underway to improve the health of North America's birds. Birder's Conservation Handbook is an indispensable resource for birdwatchers, researchers, naturalists, and conservationists. Reading it will inspire you to become an active steward of our birds and the habitats we share. A comprehensive guide to North America's one hundred most at-risk birds and how to protect them Compact and easy to use, with beautiful illustrations and data organized for convenient, at-a-glance reference Detailed species accounts, including distribution maps Practical advice on conservation Information on leading conservation agencies and resources

Shortlisted for the 2018 TWS Wildlife Publication Awards in the edited book category Lesser Prairie-Chickens have experienced substantial declines in terms of population and the extent of area that they occupy. While they are an elusive species, making it difficult at times to monitor them, current evidence indicates that they have been persistently decreasing in number since the Dust Bowl of the 1930s dramatically affected their core range. In May of 2014, the United States Fish and Wildlife Service listed Lesser Prairie-Chickens as a threatened species, granting them federal protection under the Endangered Species Act, which included a special rule recognizing significant conservation planning efforts made by state and federal wildlife agencies within the geographical range of the species. Although the listing was vacated by judicial ruling in September 2015, concern for persistence of the species persists. These actions illustrate the uncertain legal status and future conservation challenges for Lesser Prairie-Chickens. Ecology and Conservation of Lesser Prairie-Chickens provides a compendium of data, analytical results, and synthesis generated among expert wildlife biologists, conservation biologists, and ornithologists. It thoroughly reviews the life history, genetics, and ecology of the species, and is ultimately directed toward developing and establishing appropriate conservation management strategies. It presents a detailed analysis of the issues and risks relative to conservation as well as an overview of potential conservation tools. It also addresses the challenges that natural resource managers continue to face in their current conservation efforts. While dealing with immediate and short-term issues in Lesser Prairie-Chicken conservation, this book is also a useful starting point for guiding future research, management, and conservation of the species. Published in collaboration with and on behalf of The American Ornithological Society, this volume in the highly-regarded Studies in Avian Biology series provides a definitive reference for researchers, managers, and policy makers as well as those with interests in environmental science, avian biology, game bird management, or Great Plains ecology.

The past decade has seen a huge increase in the interest and attention directed toward sea ducks, the Mergini tribe. This has been inspired, in large part, by the conservation concerns associated with numerical declines in several sea duck species and populations, as well as a growing appreciation for their interesting ecological attributes. Reflecting the considerable research recently conducted on this tribe, Ecology and Conservation of North American Sea Ducks examines the 15 extant species of sea ducks from North America. Chapters are organized conceptually to focus on, compare, and contrast the ecological attributes of the tribe. Experts provide in-depth treatments of a range of topics, including: Population dynamics and genetics Infectious diseases and parasites Breeding costs and cross-seasonal affects Contaminant burdens Foraging behavior and energetics Migration strategies, molt ecology, and habitat affinities and dynamics Breeding systems and reproductive behavior Harvest history The book presents a comprehensive synthesis of sea duck ecology, documents factors that have caused population declines of some species, and provides managers with measures to enhance recovery of depressed populations of sea ducks in North America. Capturing the current state of knowledge of this unique tribe, it provides a benchmark for where we are in conservation efforts and suggests future directions for researchers, managers, students, conservationists, and avian enthusiasts.

This volume explores the South Brazilian grasslands, a unique complex of ecosystems in Brazil. Despite high biodiversity and many important ecosystem services, their biodiversity and conservation are neglected, both nationally, and globally. This book provides a state-of-the-art synthesis of knowledge on the biodiversity and its drivers in South Brazilian grasslands and associated ecosystems. Further, the book discusses conservation challenges and options, as well as management strategies that help to maintain the region’s uniqueness. The chapters present information on biodiversity and ecological features of the region, and put this information into the context of historical and current human land uses, allowing for links to global discussions of conservation and sustainable development. Altogether, the book contains 20 chapters organized in four sections. The book is directed at researchers, students and professionals working with biodiversity and sustainable development in southern Brazil, as well as to the international scientific and conservation community interested in grasslands and associated ecosystems, particularly in tropical and subtropical regions.

Golden-winged Warblers (Vermivora chrysoptera) are migratory songbirds that breed in temperate North America, primarily in the Great Lakes region with remnant populations throughout the Appalachian Mountains, and winter in Central and northern South America. Their breeding range has contracted dramatically in the Appalachian Mountains and many populations have dramatically declined, likely due to habitat loss, competition and interbreeding with Blue-winged Warblers (Vermivora pinus), andglobal climate change.. As a result of population declines in much of the eastern portion of their breeding range, Golden-winged Warblers are listed as endangered or threatened in 10 U.S. states and in Canada and have been petitioned for protection under the U.S. Endangered Species Act. Published in collaboration with and on behalf of The American Ornithological Society, this volume in the highly-regarded Studies in Avian Biology series compiles extensive, current research on Golden-winged Warblers and summarizes what is known and identifies many remaining unknowns, providing a wealth of peer-reviewed science on which future research and listing decisions can be based.
