This volume represents a first attempt at holistically classifying and mapping ecological regions across all three countries of the North American continent. A common analytical methodology is used to examine North American ecology at multiple scales, from large continental ecosystems to subdivisions of these that correlate more detailed physical and biological settings with human activities on two levels of successively smaller units. The volume begins with an overview of North America from an ecological perspective, concepts of ecological regionalization. This is followed by descriptions of the 15 broad ecological regions, including information on physical and biological setting and human activities. The final section presents case studies in applications of the ecological characterization methodology to environmental issues. The appendix includes a list of common and scientific names of selected species characteristic of the ecological regions.

Combines new findings on morphological aspects, the latest data on gene function in grasses, and the interaction of grasses with their habitats 45% of all arable land is covered by five grass crops: wheat, maize, rice, barley and sugar cane. This book demonstrates why crops and weeds are growing in characteristic environments today, and looks at how cropping practices may change in the future and how these changes will affect weed spectra. It explains the distribution of grasses and their role for mankind and summarizes our knowledge on grass genomes. Special emphasis is placed on the function of genes at defined developmental stages and in organs of grasses. The development of grasses is then described from the germination to fruit set with many unpublished examples. Grasses: Crops, Competitors and Ornamentals provides readers with a comparative description of selected grass organs (stem, root, leaf, inflorescence) and devotes several chapters to habitats of grasses and morphological characteristics that enable grasses to grow in special environments. In addition, some chapters deal with grasses as crops and weeds, and emphasis is placed on their adaptation to modern agriculture. Predicts how cropping practices may change in the future and how these changes will affect weed spectra Details grasses as crops and weeds, emphasizing their adaptation to modern agriculture Summarizes our knowledge on grass genomes Connects classical morphology with the latest tools in molecular biology as well as ecological aspects determining the wide distribution of grass species today Grasses: Crops, Competitors and Ornamentals will be of great interest to agricultural scientists who want to know more about crops and weeds, grassland specialists and breeders interested in special grass traits, and molecular biologists and ecologists who study the biology and habitat of grasses.

The first single, comprehensive source for locating North American public prairies, grasslands, and savannas, Prairie Directory of North America is a guide unlike any other. First published in 2001, the book uniquely catalogs the continent's most well-known prairie sites by country and state for easy reference. With the addition of over three hundred newly located, preserved, or restored sites, the second edition is the prairie enthusiast's ideal guide to locating countless North American sites-from the well-documented to the remote. Readers can use the guide to plan both convenient visits to close-to-home prairies and journeys to sites well across the continent. Also included is an expanded state-by-state index, ideal for locating specific prairies in any given state. The victim of destructive plowing and construction at the hands of European settlers, North American grassland ecosystems that once spanned the entire continent have suffered degradation and fragmentation. With the Prairie Directory as a guide, however, ecologists, environmental scientists, and tourists can experience the essence of this ancient ecosystem and, in some locations, even its vastness. The book lists tiny, hidden half-acre prairies spared by the plow as well as popular sites covering millions of acres. It documents prairies hidden deep in forests or in plain sight in American Indian reservations. The only one of its kind, this book will allow readers to experience the prairie as a colorful, fragrant, wildlife-rich North American landscape.

Legendary conservationists show us that we still have the power to prevent critical consequences of the sixth extinction in this game-changing book. Can we save threatened animals and ecosystems in the midst of a mass extinction? The answer is a resounding yes! Before They Vanish shows us how. In this wise and impassioned book, renowned conservation scientists Paul R. Ehrlich, Gerardo Ceballos, and Rodolfo Dirzo urge us to shift our thinking rather than succumb to grief over the losses that humanity faces. This comprehensive look at a crucial but often overlooked aspect of conservation—population extinction, or the loss of a species within a specific geographic location—guides us onto a new, hopeful path. The authors argue that conservationists have placed too much emphasis on the extinction of entire species, which occurs gradually enough that we only detect it in the direst of cases. By that time, meaningful action may be impossible. By shifting our focus to identifying extinction threats at the more localized population level, we can intervene more rapidly and effectively to prevent broader declines before it's too late. This change in perspective represents a critical step in saving these vanishing species; early detection and intervention may be our last, best hope for stemming the tide of this global crisis. Using examples from the worlds of vertebrates, invertebrates, plants, fungi, and microorganisms, the authors explain the concept of population extinction, its causes and consequences, and how to prevent the mass destruction of the amazing and unique creatures with whom we share our planet. This call to action is a must-read for anyone concerned with saving endangered and threatened species, our natural world—and ourselves.

Naturalist John James Audubon found the Great Plains and their wildlife so riveting when he visited the region in 1834 that he broke off a letter to his wife because he was too excited to write. In the almost two hundred years since then, the Wyoming landscape, deemed the “Italy of America” by landscape painter Albert Bierstadt, has retained its glory if not its place in the imagination of the American public. This book reminds us of the remarkable bounty contained in the wild beauty and rich history of the Wyoming grasslands—even as these riches are under threat from both human and natural forces. This landscape is now captured in all its spectacular diversity in the photography of Michael P. Berman and William S. Sutton, two of the modern American West’s most accomplished and well-known landscape photographers. Essays by Frank H. Goodyear, Jr., and Charles R. Preston provide a contextual framework for the images. Goodyear introduces us to the imagery of the American West and explains the place of Berman’s and Sutton’s work within that tradition, and Preston focuses on the natural history of the grasslands, illuminating the area’s ecological diversity and changes through the seasons and over the years. In 2012 Berman and Sutton launched their massive Wyoming Grasslands Photographic Project, a partnership between The Nature Conservancy, Wyoming Chapter, and the Buffalo Bill Center of the West. Working in the tradition of late-nineteenth-century explorers and photographers of the American West, Berman and Sutton shot more than 50,000 digital photographs of Wyoming prairie, from the Red Desert of southwestern Wyoming to the Thunder Basin National Grassland of the state’s northeastern corner. The best of their extraordinarily sensitive, revealing, and powerful images appear in these pages, documenting the sweep and the seasons of the Wyoming landscape. In eloquent words and pictures, including a foreword by environmental historian Dan Flores, Wyoming Grasslands offers dramatic proof of how the land that inspired the likes of Audubon and Bierstadt, while having altered over time, still holds and demands our attention.

The area of native prairie known as the Great Plains once extended from Canada to the Mexican border and from the foothills of the Rocky Mountains to western Indiana and Wisconsin. Today the declines in prairie landscape types, estimated to be as high as 99%, exceed those of any other major ecosystem in North America. The overwhelming loss of landscape and accompanying loss of species constitute a real threat to both ecological and human economic health.Prairie Conservation is a comprehensive examination of the history, ecology, and current status of North American grasslands. It presents for the first time in a single volume information on the historical, economic, and cultural significance of prairies, their natural history and ecology, threats, and conservation and restoration programs currently underway. Chapters cover: environmental history of the Great Plains the economic value of prairie prairie types -- tallgrass, mixed grass, shortgrass, wetlands -- and the ecological processes that sustain each type prairie fauna -- invertebrates, fish and other aquatic creatures, amphibians and reptiles, birds, and mammals conservation programs such as the Great Plains Partnership, Canada's Prairie Conservation Action Plan, the U.S. Prairie Pothole Joint Venture, and others The book brings together knowledge and insights from a wide range of experts to describe and explain the importance of prairies and to position them in the forefront of North American conservation efforts. Praire Conservation is an essential reference for anyone interested in prairie ecology and conservation and will play a critical role in broadening our awareness and understanding of prairie ecosystems.
