New focused text introduces readers to wetland ecosystems and systems approaches to studying wetlands With its comprehensive coverage of wetland science, management, and restoration, Mitsch and Gosselink's Wetlands has been the premier reference on wetlands for more than two decades. Now, the coverage of specific wetland ecosystem types from earlier editions of this acclaimed work has been updated, revised, and supplemented with additional content in order to create this new text focusing exclusively on wetland ecosystems. This book now complements Wetlands, Fourth Edition. Following an introduction to ecosystems in general and wetland ecosystems in particular, Wetland Ecosystems examines the major types of wetlands found throughout the world: coastal wetlands, freshwater marshes and forested swamps, and peatlands. The final chapter reviews three fundamental systems approaches to studying wetlands: mesocosms, full-scale experimental ecosystems, and mathematical modeling. This new text features: Updated descriptions of the hydrology, biogeochemistry, and biology of the main types of wetlands found in the world New content introducing general ecosystems, wetland ecosystems, whole ecosystem and mesocosm experiments with wetlands, and systems ecology and modeling A detailed description of the ecosystem services provided by wetlands A broad international scope, including many examples of wetlands located outside North America Two new coauthors offering new perspectives and additional insights into the latest ecosystem and modeling techniques An abundance of illustrations helps readers understand how different biological communities and the abiotic environment in wetland ecosystems interact and function. Tables and text boxes provide at-a-glance summaries of key information. Lastly, each chapter concludes with a list of recommended readings. This text has been designed as an introduction for students and professionals in wetland ecology and management, general ecology, environmental science, and natural resource management.

The globally important nature of wetland ecosystems has led to their increased protection and restoration as well as their use in engineered systems. Underpinning the beneficial functions of wetlands are a unique suite of physical, chemical, and biological processes that regulate elemental cycling in soils and the water column. This book provides an in-depth coverage of these wetland biogeochemical processes related to the cycling of macroelements including carbon, nitrogen, phosphorus, and sulfur, secondary and trace elements, and toxic organic compounds. In this synthesis, the authors combine more than 100 years of experience studying wetlands and biogeochemistry to look inside the black box of elemental transformations in wetland ecosystems. This new edition is updated throughout to include more topics and provide an integrated view of the coupled nature of biogeochemical cycles in wetland systems. The influence of the elemental cycles is discussed at a range of scales in the context of environmental change including climate, sea level rise, and water quality. Frequent examples of key methods and major case studies are also included to help the reader extend the basic theories for application in their own system. Some of the major topics discussed are: Flooded soil and sediment characteristics Aerobic-anaerobic interfaces Redox chemistry in flooded soil and sediment systems Anaerobic microbial metabolism Plant adaptations to reducing conditions Regulators of organic matter decomposition and accretion Major nutrient sources and sinks Greenhouse gas production and emission Elemental flux processes Remediation of contaminated soils and sediments Coupled C-N-P-S processes Consequences of environmental change in wetlands# The book provides the foundation for a basic understanding of key biogeochemical processes and its applications to solve real world problems. It is detailed, but also assists the reader with box inserts, artfully designed diagrams, and summary tables all supported by numerous current references. This book is an excellent resource for senior undergraduates and graduate students studying ecosystem biogeochemistry with a focus in wetlands and aquatic systems.

"Wetlands" has become a hot word in the current environmental debate. But what does it signify? In 1991, proposed changes in the legal definities of wetlands stirred controversy and focused attention on the scientific and economic aspects of their management. This volume explores how to define wetlands. The committee--whose members were drawn from academia, government, business, and the environmental community--builds a rational, scientific basis for delineating wetlands in the landscape and offers recommendations for further action. Wetlands also discusses the diverse hydrological and ecological functions of wetlands, and makes recommendations concerning so-called controversial areas such as permafrost wetlands, riparian ecosystems, irregularly flooded sites, and agricultural wetlands. It presents criteria for identifying wetlands and explores the problems of applying those criteria when there are seasonal changes in water levels. This comprehensive and practical volume will be of interest to environmental scientists and advocates, hydrologists, policymakers, regulators, faculty, researchers, and students of environmental studies.

The purpose of the Exploring Environmental Challenges: A Multidisciplinary Approach series is to publish a collection of short texts that each explore a specific environmental issue and describe the methodologies, theories, and findings pertaining to that issue from both natural and social science perspectives. Each text contains three natural science essays, three social science essays, and a concluding essay. Intended for introductory environmental studies courses, these balanced, thoughtful, and rigorous texts aim to provide students with a deeper understanding of the relationship between people and their environment, and to serve as a foundation for further inquiry and discussion. Wetlands introduces students to the natural ecological functions and policy issues of wetlands so they will have a solid understanding of why these ecosystems are necessary and why their governance remains a significant environmental challenge. Although not a comprehensive overview on wetlands, it does provide background material for a more comprehensive investigation into the science behind and the management of these ecosystems.

This second edition of this important and authoritative survey provides students and researchers with up-to-date and accessible information about the ecology of freshwater and estuarine wetlands. Prominent scholars help students understand both general concepts of different wetland types as well as complex topics related to these dynamic physical environments. Careful syntheses review wetland soils, hydrology, and geomorphology; abiotic constraints for wetland plants and animals; microbial ecology and biogeochemistry; development of wetland plant communities; wetland animal ecology; and carbon dynamics and ecosystem processes. In addition, contributors document wetland regulation, policy, and assessment in the US and provide a clear roadmap for adaptive management and restoration of wetlands. New material also includes an expanded review of the consequences for wetlands in a changing global environment. Ideally suited for wetlands ecology courses, Ecology of Freshwater and Estuarine Wetlands, Second Edition, includes updated content, enhanced images (many in color), and innovative pedagogical elements that guide students and interested readers through the current state of our wetlands.

This book presents 12 effective methods to manage wetlands for conservation. It offers a tool box of causal factors that can be used to protect and restore wetlands to enhance biological diversity and other functions. Each causal factor is introduced, briefly explained, and then illuminated with selected examples from around the world. The book provides a prioritized shopping list of methods for protecting and restoring wetlands. The three first and most important causal factors are flooding, fertility, and natural disturbance. Then nine other causal factors are introduced, including herbivory, sedimentation, roads, invasive species, and coarse woody debris. Each causal factor is carefully linked to the scientific literature and explained using the author’s own experience. The same list of 12 causal factors applies around the world—whether you are managing a temperate zone floodplain, a tropical peatland, a freshwater marsh, or a coastal mangrove swamp. Instead of hiring an expensive team of consultants, or pouring through hundreds of scientific papers, here is one concise guide to methods that can be immediately applied to benefit any wetland. Professor Paul Keddy has spent more than 50 years studying wetlands, and writing and lecturing about the environmental factors that control them. He has published more than 150 scholarly papers, and won multiple scientific prizes. His book Wetland Ecology is widely used to teach the principles of wetland science. Causal Factors for Wetland Management: A Concise Guide has a much simpler message: how to protect and enhance wetlands. In this concise guide, he has condensed a lifetime of experience into just 12 principles. The book is aimed at all people who protect or restore wetlands: park managers, wildlife biologists, landscape architects, engineers, environmental consultants, environmental agencies, conservation authorities, and NGOs—as well as landowners and concerned citizens. Causal Factors for Wetland Management: A Concise Guide is essential reading for anyone who cares for wetlands and wild places.

Wetlands are lands where saturation with water is the dominant factor determining the nature of soil development and the types of plant and animal communities living in the soil and on its surface. Wetlands vary widely because of regional and local differences in soils, topography, climate, hydrology, water chemistry, vegetation, and other factors, including human disturbance. Indeed, wetlands are found from the tundra to the tropics and on every continent except Antarctica. This book brings together the latest research in field.

Playing a critical role in both influencing climate change and mitigating its impacts, the world’s diverse wetlands have become one of the world’s most threatened ecosystems as unsustainable land-use practices coupled with irrational use of water have already resulted in large-scale wetlands loss and degradation. To develop sound management and conservation schemes to assure wetlands sustainability in the long term requires long-term understanding of wetlands ecology. Yet until now, long-term interdisciplinary research into these systems has been limited to only a few systems from tropical or temperate climates (such as the Florida Everglades, and Czech biosphere reserve). This new book adds to the existing wetlands literature, providing a unique reference in basic and applied Mediterranean wetland ecology, based on results from long-term interdisciplinary research at the RAMSAR and UNESCO Biosphere site, of Las Tablas de Daimiel, Spain. Dating back to the early 1990s the research highlights changes in the biotic and abiotic environment in response to cumulative anthropogenic stressors, and provide guidance on applying this understand to sound management and conservation. With particular relevance to researchers dealing with semi-arid wetlands in the Mediterranean and elsewhere, as well as to resource managers, the book discusses the complexity of the interacting abiotic and biotic environment across different spatial and temporal scales and across various levels of biological hierarchy is highlighted, and reveals how management based on poor knowledge causes more damage than repair. The book will be of interest to researchers interested in freshwater ecology, hydrobotany, hydrology, geology, biogeochemistry, landscape ecology and environmental management.

Despite our growing awareness of the vital role they play in the global environment, wetlands remain among the most endangered ecosystems on Earth and are still being destroyed and degraded at an alarming rate. This much-needed publication, which includes contributions from leading researchers and practitioners, presents a holistic perspective on the restoration of wetland ecosystems such as shallow lakes, streams, floodplains and bogs. Through the use of carefully chosen case studies, the authors examine European wetland restoration projects from Scandinavia to Bulgaria and from Ireland to Belarus, focusing on the lessons they can teach to a new generation of conservationists. As well as reviewing the sum of current knowledge on the subject, the text is a store of practical know-how, covering a wide range of conservation approaches and techniques. It analyzes the major problems in the field and identifies key principles for achieving sustainability in wetland restoration. The topics covered include: • the role of wetlands in landscape functioning • human interference with natural processes such as water and matter cycles and energy dissipation • the impact of land use on global problems such as climate change, floods and droughts • the role played by diversity in wetland functioning The work shows that without sustainable land use over the totality of their catchment areas, and without cohesive inter-agency cooperation, individual restoration projects will have a short life span. The balance between scientific background and practical restoration makes this book a valuable resource for scientists as well as wetland managers, decision makers and land use planners, as well as students of ecology, nature conservation and environmental protection.
