Wetlands are very sensitive ecosystems, functioning as a habitat for many organisms. Protection and regeneration of wetlands are of great importance in ecological research and in nature conservation. A huge amount of research has been done on the hydrology, plants and animals in wetlands. Knowledge about soil organisms and soil ecological processes of wetlands is still lacking. This knowledge is a prerequisite for landscape planning purposes or climate change predictions. In the case of climate change, trace gas emissions from wetlands are of great interest. The authors provide an overview of the state-of-the-art on soil ecology in wetlands. The book is divided into the following main chapters: 'Wetlands as habitats for soil organisms', 'Soil ecological processes in fens and floodplains', 'Carbon and nitrogen dynamics in soils with different water regimes' and 'Trace gas emissions'.

The impetus for this volume was the 2nd International Wetlands Conference which was held in June, 1984 at Trebon, Czechoslovakia. An overview of the worlds wetlands was one of the themes of the conference and it was decided that a useful follow-up would be a publication on the same topic. The initial goal was to cover as many of the worlds wetlands as possible in one volume and to have an emphasis on wetland ecology, biota, classification, and management. Individuals who made presentations at the Trebon confer ence were asked to prepare chapters and the editors also solicited other contributions. For a variety of reasons, the initial goal has been difficult to reach, especially coverage of the entire globe, and it has been necessary to publish the contributions in more than one volume. Volume 1 represents the com pletion of the first phase of the project and it covers most of the Western Hemisphere, Australia, most of Africa, the Indian subcontinent, the Mediter ranean region, and Papua New Guinea. Volume 2 will contain chapters on Western Europe, Northern Europe, Central Europe, most of northern and It is our hope that Volume western Asia, the Middle East, and Indonesia. 2 will appear in the near future and, if possible, a third volume will be published if authors can be secured to cover areas such as the Far East, other parts of the Indo-Pacific region, and New Zealand.
