This book brings together, for the first time, information on various wetland classification systems and wetland inventories from around the world, outlining regional, national and local wetland classifications developed in Africa, Australia, Canada, China, Europe, India, South America and the USA. Oriented towards the conservation and management of wetlands, these existing national and regional classification systems have been useful in providing an essential base for the development of an international system. The volume also reviews various attempts at drawing up an inventory of wetlands...

This volume contains most of the contributions presented at the Symposium on Vegetation dynamics in grasslands, heathlands, and mediterranean ligneous formations, which took place at the Centre d'Etudes Phytosociologiques et Ecologiques 'Louis Emberger' (locally organized by the Department of General Ecology and the Directory Staff of this institute) at Montpellier. It was organized by the Working Group for Succession research on permanent plots, and the Working Group for Data-processing in phytosociology, both of the International Society for Vegetation Science. The editors of this volume...

July 8 -13, 1985, an international group of scientists met in Uppsala for a symposium on the subject 'Theory and models in Vegetation science' . A volume of over 70 extended abstracts had already been published in time for the symposium (Leemans et at., 1985). That volume included contributions from nearly all of those who gave talks or presented posters at the symposium. The present volume represents the fully-refereed proceedings of the symposium and features articles by a majority of speakers, plus a handful by poster authors, and two that were sent independently to Vegetatio and seemed...

This book is the result of a symposium dedicated to the 25th anniversary of the Delta Institute for Hydrobiological Research in Yerseke, the Netherlands. The primary idea did not come from one of the scientists working in this Institute, but from the second editor. Long before the Institute celebrated itsjubilee on 20-23 October 1982, he expressed his feelings to the other editors, that the time had come for a second European symposium on the ecology of coastal vegetation. The first symposium on this theme was held in Norwich, 12-16 September 1977, being the first meeting of the European...
