Book Description
Articles by prominent archaeologists and geological scientists shed new light on the late Palaeo-Indian cultures of the Great Lakes during a time of staggering environmental change and challenge, as the ice sheets retreated northward. The human response to the dramatic environmental upheaval produced unique cultural patterns, which we are just beginning to understand.

Book Description
Principles and Dynamics of the Critical Zone is an invaluable resource for undergraduate and graduate courses and an essential tool for researchers developing cutting-edge proposals. It provides a process-based description of the Critical Zone, a place that The National Research Council (2001) defines as the "heterogeneous, near surface environment in which complex interactions involving rock, soil, water, air, and living organisms regulate the natural habitat and determine the availability of life-sustaining resources." This text provides a summary of Critical Zone research and outcomes from the NSF funded Critical Zone Observatories, providing a process-based description of the Critical Zone in a wide range of environments with a specific focus on the important linkages that exist amongst the processes in each zone. This book will be useful to all scientists and students conducting research on the Critical Zone within and outside the Critical Zone Observatory Network, as well as scientists and students in the geosciences – atmosphere, geomorphology, geology and pedology. - The first text to address the principles and concepts of the Critical Zone - A comprehensive approach to the processes responsible for the development and structure of the Critical Zone in a number of environments - An essential tool for undergraduate and graduate students, and researchers developing cutting-edge proposals

Book Description
Precision conservation is a reality, and we are moving towards improved effectiveness of conservation practices by accounting for temporal and spatial variability within and off field. This is the first book to cover the application of the principles of precision conservation to target conservation practices across fields and watersheds. It has clearly been established that the 21st century will present enormous challenges, from increased yield demands to climate change. Without improved conservation practices it will not be possible to ensure food security and conservation effectiveness. Readers will appreciate the application of the precision conservation concept to increase conservation effectiveness in a variety of contexts, with a focus on recent advances in technology, methods, and improved results. IN PRESS! This book is being published according to the “Just Published” model, with more chapters to be published online as they are completed.

Book Description
Landscapes of the Northern Great Plains have been constantly changing, but never so rapidly as under modern conditions of economic affluence and technological development. This change is multifaceted and has an impact not only on the fabric of culture and its perception of landscape, but also on the ecology and physical landforms. Multidisciplinary research has therefore become an important tool in identifying the influences that human activities have, not only on cultural landscapes but on biophysical ones as well. This collection of articles, originating in a conference held at the Royal Saskatchewan Museum in April 2000, focuses on just such an integration of research concerning the Great Plains of North America and involving the disciplines of geology, archaeology, biology, geography, sociology, and agriculture.

Book Description
Understand the current concept of wetland and methods for identifying, describing, classifying, and delineating wetlands in the United States with Wetland Indicators - capturing the current state of science's role in wetland recognition and mapping. Environmental scientists and others involved with wetland regulations can strengthen their knowledge about wetlands, and the use of various indicators, to support their decisions on difficult wetland determinations. Professor Tiner primarily focuses on plants, soils, and other signs of wetland hydrology in the soil, or on the surface of wetlands in his discussion of Wetland Indicators. Practicing - and aspiring - wetland delineators alike will appreciate Wetland Indicators' critical insight into the development and significance of hydrophytic vegetation, hydric soils, and other factors. Features Color images throughout illustrate wetland indicators. Incorporates analysis and coverage of the latest Army Corps of Engineers delineation manual. Provides over 60 tables, including extensive tables of U.S. wetland plant communities and examples for determining hydrophytic vegetation.

Book Description
Bridging the fields of ecosystem science and landscape ecology, this book integrates Dr. Carol Johnston's research on beaver ecosystem alteration at Voyageurs National Park. The findings about the vegetation, soils, and chemistry of beaver impoundments synthesized in the text provide a cohesive reference useful to wetland scientists, ecosystems and landscape ecologysts, wildlife managers, and students. The beaver, Castor canadensis, is an ecosystem engineer unequaled in its capacity to alter landscapes through browsing and dam building, whose population recovery has re-established environmental conditions that probably existed for millenia prior to its near extirpation by trapping in the 1800s and 1900s. Beavers continue to regain much of their natural range throughout North America, changing stream and forest ecosystems in ways that may be lauded or vilified. Interest in beavers by ecologists remains keen as new evidence emerges about the ecological, hydrological, and biogeochemical effects of beaver browsing and construction. There is a critical need for ecologists and land managers to understand the potential magnitude, persistence, and ecosystem services of beaver landscape transformation. The 88-year record of beaver landscape occupation and alteration documented by Dr. Carol Johnston and colleagues from aerial photography and field work provides a unique resource toward understanding the ecosystem effects and sustainability of beaver activity.

Book Description
Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 194. Stream Restoration in Dynamic Fluvial Systems: Scientific Approaches, Analyses, and Tools brings together leading contributors in stream restoration science to provide comprehensive consideration of process-based approaches, tools, and applications of techniques useful for the implementation of sustainable restoration strategies. Stream restoration is a catchall term for modifications to streams and adjacent riparian zones undertaken to improve geomorphic and/or ecologic function, structure, and integrity of river corridors, and it has become a multibillion dollar industry. A vigorous debate currently exists in research and professional communities regarding the approaches, applications, and tools most effective in designing, implementing, and assessing stream restoration strategies given a multitude of goals, objectives, stakeholders, and boundary conditions. More importantly, stream restoration as a research-oriented academic discipline is, at present, lagging stream restoration as a rapidly evolving, practitioner-centric endeavor. The volume addresses these main areas: concepts in stream restoration, river mechanics and the use of hydraulic structures, modeling in restoration design, ecology, ecologic indices, and habitat, geomorphic approaches to stream and watershed management, and sediment considerations in stream restoration. Stream Restoration in Dynamic Fluvial Systems will appeal to scholars, professionals, and government agency and institute researchers involved in examining river flow processes, river channel changes and improvements, watershed processes, and landscape systematics.
