Global wetlands range from moss-dominated artic peatlands to seasonally-flooded tropical floodplains, and exhibit significant differences in both hydrology and species composition. However, rather than concentrating on the detailed characteristics of specific wetland types, this concisetextbook emphasizes their universal environmental and biological features. A combination of hydrology, low oxygen levels, and dense plant canopies are the major defining features of wetland habitats. Due to the slow diffusion of oxygen in water, oxygen in wetland soils and water columns is oftenvery low or absent. The adaptations of wetland micro-organisims, invetebrates, plants, and vetebrates to anaerobic conditions (and ther functional consequences) are a major theme of this book. Plant canopies create complex gradients of light, temperature and oxygen that change daily and seasonally.The book demonstrates how these shifting environmental gradients are responsible for the distribution of algae, invertebrates, and vertebrates in wetlands. Another major focus is on water level fluctuations and how they can affect the flora, fauna, and functions of wetlands. The future of wetlandsis also examined, including the potential impacts of global climate change and efforts to restore wetlands.

Global wetlands exhibit significant differences in both hydrology and species composition and range from moss-dominated arctic peatlands to seasonally-flooded tropical floodplains. They are increasingly recognized for the important services that they provide to both the environment and human society such as wildlife and fish production, nutrient filtering, and carbon sequestration. A combination of low oxygen levels and dense plant canopies present particular challenges for organisms living in this aquatic habitat. This concise textbook discusses the universal environmental and biological features of wetland habitats, with an emphasis on wetland plants and animals and their adaptations. It also describes the functional features of wetlands - primary production, litter decomposition, food webs, and nutrient cycling - and their significance locally and globally. The future of wetlands is examined, including the potential threats of global climate change and invasive species, as well as their restoration and creation. This new edition maintains the structure and style of the first, but is fully updated throughout with new chapters on invasive species, restoration/creation, global climate change, and the value of wetlands.

The first resource of its kind-essential practical guidance on wetlands bioassessment and management Although bioassessment has become a vital tool in the successful management of many aquatic ecosystems, to date there has been no single book that covers the application of bioassessment principles to wetland ecosystems. This contributed volume fills this important gap in the literature, with a multifaceted look at the issues and techniques involved in the successful bioassessment and management of freshwater wetlands. The book is divided into two parts-bioassessment and wildlife management. After a review of general bioassessment principles, Part I discusses the statistical issues related to sampling numerous sites, as well as the application of multivariate procedures and invertebrate functional groups to wetland bioassessment. A series of case studies examines bioassessment results using various organismal groups, followed by several chapters that trace the relationship between bioassessment and wetland restoration. Coverage also explores how to use and sample bacteria, algae, macrophytes, and invertebrates. Part II covers key management topics, including many that are frequently overlooked in other treatments of the subject. Separate chapters discuss how to manage fish, waterbirds, and mosquitoes in wetlands. Other chapters address timber harvest strategies and impact assessment, as well as the biological control of an invasive wetland plant. As wetland managers work to strike a vital balance between resource exploitation and resource protection, this book offers an important repository of practical information to use in meeting this formidable challenge. It will be welcomed by wetland managers and scientists, environmental engineers, ecologists, civil engineers, and others whose work involves wetlands study and management.

Peatlands form important landscape elements in many parts of the world and play significant roles for biodiversity and global carbon balance. This new edition has been fully revised and updated, documenting the latest advances in areas such as microbial processes and relations between biological processes and hydrology. As well as thoroughly referencing the latest research, the authors expose a rich older literature where an immense repository of natural history has accumulated. The Biology of Peatlands starts with an overview of the main peatland types (marsh, swamp, fen, and bog), before examining the entire range of biota present (microbes, invertebrates, plants, and vertebrates), together with their specific adaptations to peatland habitats. Detailed coverage is devoted to the genus Sphagnum, the most important functional plant group in northern peatlands, although tropical and southern hemisphere peatlands are also covered. Throughout the book the interactions between organisms and environmental conditions (especially wetness, availability of oxygen, and pH) are emphasized, with chapters on the physical and chemical characteristics of peat, the role of peat as an archive of past vegetation and climate, and peatland succession and development. Several other key factors and processes are then examined, including hydrology and nutrient cycling. The fascinating peatland landforms in different parts of the world are described, together with theories on how they have developed. Human interactions with peatlands are considered in terms of management, conservation, and restoration. A final chapter, new to this edition, focuses on the role of peatlands as sources or sinks for the greenhouse gases carbon dioxide and methane, and the influences of climate change on peatlands. This timely and accessible text is suitable for students and researchers of peatland ecology, as well as providing an authoritative overview for professional ecologists and conservation biologists.

Wetlands are among the world’s most valuable and most threatened habitats, and in these crucially important ecosystems, the invertebrate fauna holds a focal position. Most of the biological diversity in wetlands is found within resident invertebrate assemblages, and those invertebrates are the primary trophic link between lower plants and higher vertebrates (e.g. amphibians, fish, and birds). As such, most scientists, managers, consultants, and students who work in the world’s wetlands should become better informed about the invertebrate components in their habitats of interest. Our book serves to fill this need by assembling the world’s most prominent ecologists working on freshwater wetland invertebrates, and having them provide authoritative perspectives on each the world’s most important freshwater wetland types. The initial chapter of the book provides a primer on freshwater wetland invertebrates, including how they are uniquely adapted for life in wetland environments and how they contribute to important ecological functions in wetland ecosystems. The next 15 chapters deal with invertebrates in the major wetlands across the globe (rock pools, alpine ponds, temperate temporary ponds, Mediterranean temporary ponds, turloughs, peatlands, permanent marshes, Great Lakes marshes, Everglades, springs, beaver ponds, temperate floodplains, neotropical floodplains, created wetlands, waterfowl marshes), each chapter written by groups of prominent scientists intimately knowledgeable about the individual wetland types. Each chapter reviews the relevant literature, provides a synthesis of the most important ecological controls on the resident invertebrate fauna, and highlights important conservation concerns. The final chapter synthesizes the 15 habitat-based chapters, providing a macroscopic perspective on natural variation of invertebrate assemblage structure across the world’s wetlands and a paradigm for understanding how global variation and environmental factors shape wetland invertebrate communities.

"Wetland Habitats of North America is essential reading for everyone who studies, manages, or visits North American wetlands. It fills an important void in the wetland literature, providing accessible and succinct descriptions of all of the continent's major wetland types." Arnold van der Valk, Iowa State University "Batzer and Baldwin have compiled the most comprehensive compendium of North American wetland habitats and their ecology that is presently available--a must for wetland scientists and managers." Irving A. Mendelssohn, Louisiana State University "If you want to gain a broad understanding of the ecology of North America's diverse wetlands, Wetland Habitats of North America is the book for you. Darold Batzer and Andrew Baldwin have assembled an impressive group of regional wetland scientists who have produced a virtual encyclopedia to the continent's wetlands. Reading the book is like a road trip across the Americas with guided tours of major wetland types by local experts. Your first stop will be to coastal wetlands with eight chapters covering tidal wetlands along the Atlantic, Gulf, and Pacific coasts. Then you'll travel inland where you can visit any or all of 18 types ranging from bottomland swamps of the Southeast to pothole marshes of the Northern Prairies to montane wetlands of the Rockies to tropical swamps of Central America and desert springs wetlands. All in one book--I'm impressed! Every wetlander should add this book to her or his swampland library. Ralph Tiner, University of Massachusetts-Amherst

In The Big Muddy, the first long-term environmental history of the Mississippi, Christopher Morris offers a brilliant tour across five centuries as he illuminates the interaction between people and the landscape, from early hunter-gatherer bands to present-day industrial and post-industrial society. Morris shows that when Hernando de Soto arrived at the lower Mississippi Valley, he found an incredibly vast wetland, forty thousand square miles of some of the richest, wettest land in North America, deposited there by the big muddy river that ran through it. But since then much has changed, for the river and for the surrounding valley. Indeed, by the 1890s, the valley was rapidly drying. Morris shows how centuries of increasingly intensified human meddling--including deforestation, swamp drainage, and levee construction--led to drought, disease, and severe flooding. He outlines the damage done by the introduction of foreign species, such as the Argentine nutria, which escaped into the wild and are now busy eating up Louisiana's wetlands. And he critiques the most monumental change in the lower Mississippi Valley--the reconstruction of the river itself, largely under the direction of the Army Corps of Engineers. Valley residents have been paying the price for these human interventions, most visibly with the disaster that followed Hurricane Katrina. Morris also describes how valley residents have been struggling to reinvigorate the valley environment in recent years--such as with the burgeoning catfish and crawfish industries--so that they may once again live off its natural abundance. Morris concludes that the problem with Katrina is the problem with the Amazon Rainforest, drought and famine in Africa, and fires and mudslides in California--it is the end result of the ill-considered bending of natural environments to human purposes.

The lands and waters of the Mid-Atlantic Region (MAR) have changed significantly since before the 16th century when the Susquehannock lived in the area. Much has changed since Captain John Smith penetrated the estuaries and rivers during the early 17th century; since the surveying of the Mason-Dixon Line to settle border disputes among Maryland, Pennsylvania, and Delaware during the middle of the 18th century; and since J. Thomas Scharf described the physiographic setting of Baltimore County in the late 19th century. As early as 1881, Scharf provides us with an assessment of the condition of the aquatic ecosystems of the region, albeit in narrative form, and already changes are taking place – the conversion of forests to fields, the founding of towns and cities, and the depletion of natural resources. We have always conducted our work with the premise that “man” is part of, and not apart from, this ecosystem and landscape. This premise, and the historical changes in our landscape, provide the foundation for our overarching research question: how do human activities impact the functioning of aquatic ecosystems and the ecosystem services that they provide, and how can we optimize this relationship?

A detailed account of the biology and ecology of vascular wetland plants and their applications in wetland plant science, Wetland Plants: Biology and Ecology presents a synthesis of wetland plant studies and reviews from biology, physiology, evolution, genetics, community and population ecology, environmental science, and engineering. It provides a thorough discussion of the range of wetland plants adaptations to conditions such as life in water or saturated soils, high salt or high sulfur, as well as low light and low carbon dioxide levels. The authors include the latest research on the development of plant communities in newly restored or created wetlands and on the use of wetland plants as indicators of ecological integrity and of wetland boundaries. Over 140 figures, including over 70 original photographs, allow you to visualize the concepts, 40 tables give you easy access to definitions and data, and international examples provide you with a broad base of information. The growing consensus in wetlands literature and research suggests that methods are needed to assess the ecological health or integrity of wetlands, to set goals for wetland restoration, and to track the status and trends of wetlands. Wetland plants are emerging as important indicators, and becoming an important part of this research. Wetland Plants: Biology and Ecology contains up-to-date information on this increasingly important area in wetlands technology.

Although public interest in wetlands has grown considerably in recent years, the associated issues of legislation and environmental policy are often confused by the need to correctly define a wetland area. Much of the difficulty comes from an inability to identify wetland indicator species and to determine whether a given area contains a significant proportion of such plants. The 182 species treated in this work represent the fast majority of genera commonly encountered in freshwater wetlands throughout the Northeast, consequently, this will prove an invaluable book for those concerned with how a correct definition of wetland areas affects decisions about land use, development, and/or conservation. Following a brief introduction that discusses the functional values of wetlands and describes their various types, the manual is organized into two major components, the first consisting of keys that are based on life form and arrangement of plant parts, the second consisting of a description of each species. Such factors as range, habitat, general characteristics, stem, leaves, inflorescence, fruit, and similar species are covered in the descriptions.
