During the past century approximately fifty percent of the world's wetlands have been destroyed, largely due to human activities. Increased human population has lead to shrinkage of wetland areas, and data show that as they shrink, their important functions decline. Reduced wetland area causes more flooding in Spring, less available water during drought, greater risk of water pollution, and less food production and reduced carbon storage. Much of the remaining pristine wetland systems are found in the world's largest wetlands, and yet these areas have received surprisingly little scientific research or attention. This volume presents the views of leading experts on each of the world's largest wetland systems. Here, this international team of authors share their understanding of the ecological dynamics of large wetlands and their significance, and emphasise their need of conservation.

This book addresses an important problem in ecology: how are communities assembled from species pools? This pressing question underlies a broad array of practical problems in ecology and environmental science, including restoration of damaged landscapes, management of protected areas, and protection of threatened species. This book presents a simple logical structure for ecological assembly and addresses key areas including species pools, traits, environmental filters, and functional groups. It demonstrates the use of two predictive models (CATS and Traitspace) and consists of many wide-ranging examples including plants in deserts, wetlands, and forests, and communities of fish, amphibians, birds, mammals, and fungi. Global in scope, this volume ranges from the arid lands of North Africa, to forests in the Himalayas, to Amazonian floodplains. There is a strong focus on applications, particularly the twin challenges of conserving biodiversity and understanding community responses to climate change.

Richly illustrated in colour and packed with examples from every major continent and wetland type, this third edition has been completely rewritten to provide undergraduates with a thoroughly accessible introduction to the basic principles. It divides the world's wetlands into six principal types and presents six major causal environmental factors, arranged by importance and illustrated with clear examples, making it easy for instructors to plan tailored lectures and field trips and avoid overwhelming students with unnecessary detail. It retains its rigor for more advanced students with sections on research methods and experiments, and over a thousand classic and contemporary references. Each chapter ends with questions that review the content covered and encourage further investigation. With expanded sections on topical issues such as sea level rise, eutrophication, facilitation and the latest approaches to restoration and conservation, the new edition of this prize-winning textbook is a vital resource for wetland ecology courses.

Presenting a global and interdisciplinary approach to plant ecology, this much-awaited new edition of the book Plants and Vegetation integrates classical themes with the latest ideas, models, and data. Keddy draws on extensive teaching experience to bring the field to life, guiding students through essential concepts with numerous real-world examples and full-colour illustrations throughout. The chapters begin by presenting the wider picture of the origin of plants and their impact on the Earth, before exploring the search for global patterns in plants and vegetation. Chapters on resources, stress, competition, herbivory, and mutualism explore causation, and a concluding chapter on conservation addresses the concern that one-third of all plant species are at risk of extinction. The scope of this edition is broadened further by a new chapter on population ecology, along with extensive examples including South African deserts, the Guyana Highlands of South America, Himalayan forests and arctic alpine environments.

Louisiana is one of the most beautiful parts of North America. It offers much more than Mardi Gras and Bourbon Street. With 25 maps and 60 illustrations, this is the first book to introduce the full range of wild places in Louisiana. Certainly the states magnificent swamps are described, but Louisiana showcases a great diversity of natural habitats prairies, longleaf pine savannas, oak forests, Appalachian forest, river valleys, cliffs, sand dunes, and cheniers. Each has its distinctive plant and animal species. Frogs living in trees, fish digging burrows, pelicans nesting on offshore islands and plants eating insects, as well as wild orchids, dwarf palmettos, armadillos, and Some of the authors favorite places to visit are highlighted and he describes the challenge of conserving wild places for the enjoyment of future generations. The book is titled for the water that carries the earth that builds Louisiana, and the fires that create the prairies, pine forests, and savannas. If you own only one book about Louisiana nature, this is the one to have a perfect gift for student, tourist, hunter, or neighbor.Advance PraiseThis is an impressive guide to the magical and bountiful world of Louisiana nature,and an excellent primer in why we should save itnot only for the sake of pelicansand woodpeckers and tupelos, but for the sake of ourselves.Michael Grunwald, author of The Swamp: The Everglades, Florida and thePolitics of ParadiseDr. Paul Keddy captures what truly is the best about Louisianaits many and variednatural habitats. Dr. Keddy is more than a gifted scientist. He takes the science out ofscience. He describes complex processes in terms that are easy to understand, enlightening,and enjoyable. From the rolling pine forest to cypress swamps to barrier islands; frombirds to bugs to bears; from frogs to fi sh, Dr. Keddy covers all that makes Louisiana oneof the most unique places on the good planet Earth.Carlton Dufrechou, Executive Director, Lake Pontchartrain Basin Foundation

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.
