Book Description
With detailed data from nine sites around the world, the authors examine how the so-called ‘fragmentation’ of these fragile landscapes occurs and the consequences of this break-up for ecosystems and the people who depend on them. ‘Rangelands’ make up a quarter of the world’s landscape, and here, the case is developed that while fragmentation arises from different natural, social and economic conditions worldwide, it creates similar outcomes for human and natural systems.

Book Description
Woody wetlands constitute a relatively small but extremely important part of the landscape in the southwestern United States. These riparian habitats support more than one-third of the regionÕs vascular plant species, are home to a variety of wildlife, and provide essential havens for dozens of migratory animals. Because of their limited size and disproportionately high biological value, the goal of protecting wetland environments frequently takes priority over nearly all other habitat types. In The Ribbon of Green, hydrologists Robert H. Webb, and Stanley A. Leake and botanist Raymond M. Turner examine the factors that affect the stability of woody riparian vegetation, one of the largest components of riparian areas. Such factors include the diversion of surface water, flood control, and the excessive use of groundwater. Combining repeat photography with historical context and information on species composition, they document more than 140 years of change. Contrary to the common assumption of widespread losses of this type of ecosystem, the authors show that vegetation has increased on many river reaches as a result of flood control, favorable climatic conditions, and large winter floods that encourage ecosystem disturbance, germination, and the establishment of species in newly generated openings. Bringing well-documented and accessible insights to the ecological study of wetlands, this book will influence our perception of change in riparian ecosystems and how riparian restoration is practiced in the Southwest, and it will serve as an important reference in courses on plant ecology, riparian ecology, and ecosystem management.

Book Description
"The bibliography is a guide to recent scientific literature covering effects of agricultural conservation practices on fish and wildlife. The citations listed here provide information on how conservation programs and practices designed to improve fish and wildlife habitat, as well as those intended for other purposes (e.g., water quality improvement), affect various aquatic and terrestrial fauna"--Abstract.

Book Description
An illustrated review of the Northern Great Plains that blends natural history and human history "The most complete, in-depth look at Dakota ecosystems and their history. An absolutely fascinating read!"--Gabe Brown, author of Dirt to Soil W. Carter Johnson and Dennis H. Knight describe the natural and human histories of the Northern Great Plains in this comprehensive and handsomely illustrated book. Covering a vast period of time, they move from geological developments millions of years ago and the effects of glaciers to historical and ecological developments in recent centuries and the effects of agriculture. The book ends with a discussion of the future of this region, mediated by climate change, with recommendations on how to balance agriculture and other pressing needs in the twenty-first century. Johnson and Knight bring decades of experience to chapters on the major ecosystems of the Dakotas. Written for readers with varying backgrounds, and with discussions of the Prairie Pothole Region, the Missouri River, grasslands, woodlands, the Black Hills, and rivers, lakes, and wetlands, the book is unique and will become a long-lasting source of information. Readers will appreciate the plentiful photographs and other color illustrations.

Book Description
Currently, anthropogenic activities have caused unprecedented destruction of the environment at alarming rates, leading to undesirable alterations in air, land, and water. The process of environment degradation has been accelerated by industrial processes, which result in waste as well as over-consumption of natural resources. The ecological balance has been disturbed, and resources have shrunk. All this has resulted in climate change, which has emerged as a major concern in the 21st century. Changes in the environment are driven by demand for energy, water, and food to raise the standard of living. These are also responsible for climate change, with contributions from deforestation and CO2 emissions from fossil fuels such as coal and petroleum. The present volume discusses some of the main issues regarding environmental degradation and the causes as well as the impact of climate change, which is impacting the ecosystem. The effects of various pollutants, causes of climate change with case studies on geochemistry and glaciers, etc., and measures to reduce the impact on biodiversity, health, etc. are discussed in detail in its chapters. In a nutshell, this volume discusses in detail the following issues: • Anthropogenic and natural factors in environmental degradation • Climate change history, causes, and threats to abiotic and biotic systems • Case studies on the impact of climate change and living systems • Mitigation and preparedness for the future
