From the preface:

This volume resulted from the workshop entitled "Nutrient Cycling and Retention in Natural and Constructed Wetlands 111" which was held at Hotel Perslak near Treboit in the Czech Republic on September 14-19, 1999. In order to avoid confusion with the previous proceedings with the same title we decided to change the title of the book to "Transformations of Nutrients in Natural and Constructed Wetlands".
The workshop was attended by 35 participants from 13 countries from Europe, Australia and North America. The theme of the workshop covered the following topics: nutrient cycling in natural and constructed wetlands, carbon transformations in wetlands, retention mechanisms and wetlands capacity, use of constructed wetlands for various types of wastewater, retention nutrients by macrophytes, physiological response of macrophytes to nutrient loads, water cycles, budgets and evapotranspiration, wetland restoration or ecological functional assessment of wetlands.
The workshop was planned, similar to two preceding workshops in 1995 and 1997, to provide an opportunity for "applied" scientists working on functioning constructed wetlands for wastewater treatment to meet scientists studying processes occurring in natural wetland ecosystems. The idea of bringing both groups of scientists together proved again to be very useful and we believe that both groups benefited from the exchange of experience. The workshop was organized by Jan Vymazal (Ecology and Use of Wetlands, Prague) and Jan Pokorny (Institute of Botany, Czech Academy of Sciences, Trebon) and was partially supported by grant GA CR 206/98/0727.
During the workshop 27 papers were presented orally and 3 poster papers were displayed. This book contains 25 refereed contributions including all posters (J. Pokorny, P. Pokorny and Piknova & Kvet). All oral presentations also include discussion which was taped after the presentation and then "recovered" by the editor. The discussion was left as it proceeded despite the fact that some questions could be "answered" in the paper as a result of reviewers' comments. The two papers by Dusek et al. were presented as one contribution but the authors decided to split this paper and, therefore, the complete discussion is included only after the paper by Dusek and Kvet.
The editor wants to thank all contributing authors for their effort and under-standing with which they accepted editor's ideas, comments and requirements. The editor also wants to thank the publisher, Mr. Wil R. Peters, for his excellent help during the process of book edition and his support of this project.
