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.

"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

Ecological engineering involves the design, construction and management of ecosystems that have value to both humans and the environment. It is a rapidly developing discipline that provides a promising technology to solve environmental problems. Ecological Engineering covers the basic theory of ecological engineering as well as the application of these principles in environmental management. Provides an overview of the theory and application of environmental engineering International focus and range of ecosystems makes Ecological Engineering an indispensable resource to scientists Based on the best-selling Encyclopedia of Ecology Full-color figures and tables support the text and aid in understanding

This volume is the first in a series entitled Conservation Ecology: Principles, Practices and Management, a theme which Elsevier's pioneer ing journal Biological Conservation has promoted since its foundation thirty-three years ago. The science of conservation ecology is now widely acknowledged as an essential component in the planning and develop ment of activities which change or modify our natural environment. Nevertheless in spite of much research and publicity, there is still a wide gap between theory and practice. Today it is especially important to try to bridge this gap by interpreting the results of ecological research so that they are understandable and relevant to a wide range of land managers, agriculturalists, foresters, and those working in the many categories of protected areas. The volumes in this series are designed to fulfil this purpose, and also to play an important educational role for students of the environmental sciences in schools, universities and other institutions.

Wussten Sie, dass Sie mit einem Röhrling näher verwandt sind als mit einem Gänseblümchen oder Vögel den Krokodilen näher sind als Eidechsen? In den letzten 30 Jahren sind die Methoden der Klassifikation des Lebens völlig neu überdacht worden. Das Resultat stellt die bisherige Einteilung der mehr als 2 Millionen bekannten Arten auf den Kopf. Das Buch hilft, die organismische Vielfalt zu bewältigen, indem wesentliche Einteilungs- und Ordnungskriterien vorgestellt und bedeutende stammesgeschichtliche Entwicklungslinien diskutiert werden.

Alle Welt redet von schwindenden Energieressourcen; dass sich daneben eine ungleich gravierendere Wasserkrise anbahnt, ist bis jetzt kaum ins Bewusstsein gedrungen. Selbst wer umweltbewusst zu Hause Wasser spart, weiss selten, wieviel ”virtuelles Wasser“ er über Nahrung und Kleidung tatsächlich verbraucht: 5.000 Liter Wasser sind nötig, um ein Kilo Reis zu erzeugen, 11.000 Liter für das Rindfleisch eines Hamburgers, unglaubliche 20.000 Liter stecken in 1 kg Kaffeepulver. Kein Wunder, dass sich die Flüsse der Welt in atemberaubendem Tempo leeren, während durch Überregulierung andererseits die Flutgefahr dramatisch steigt. Längst weiss man, dass gigantomanische Bewässerungs- und Staudammprojekte eine enorme ökologische und ökonomische Verschwendung darstellen. Doch schon geht man weltweit dazu über, auch die unterirdischen Wasserreservoirs leer zu pumpen. Ressourcenkriege um Wasser bahnen sich an, denn: Ohne Öl können wir zur Not leben, ohne Wasser sicher nicht. Fred Pearces Berichte lesen sich wie Kriminalgeschichten und geben zugleich einen umfassenden Überblick über die Wasserkrise und ihre Auswirkungen.
