and system ecological literature, covering the same topics, as they don't refer to many important papers on these topics, which would strongly support their view points. All by all a very interesting book focusing on an extremely important topic for every one interested in ecological modelling and systems ecology.

Dynamics of Environmental Bioprocesses, Modelling and Simulation, by J.B. Snarpe, l.J. Dunn, J. Ingham and J.E. Prenosil. VHC Weinheim, New York, Basel, Cambridge and Tokyo, 1995. Hardbound, Price DM 258, ISBN 3-527-28705-1, 492 pages and with a software diskette. This is a textbook on the application of modelling in environmental technology. The book is divided into three chapters covering respectively, principles of modelling and an overview of the basic sub models, environmental bioprocess description and illustrative simulation examples. The first chapter gives the basic theory. It opens with a discussion of the need for models in environmental technology and a brief overview of model classification and the adapted modelling procedure. The formulation of mass and energy balances, a central theme in modelling, is presented in great details. It is furthermore shown how it is possible to include transportation processes, reactor processes and chemical-microbiological kinetics in the formulation. The second chapter provides background information on various environmental bioprocesses. Waste water, its characteristics, analyses and treatment is covered. The equations describing aerobic, anaerobic, chemical, biofilm and biofloc processes are all presented and comments to their applicability are given. The chapter also encompasses water pollution modelling: the eutrophication of lakes and reservoirs, the discharge of organic matter into river and streams and ground water pollution.
The third and final chapter comprises 65 simulation examples, all of which are on the diskette and which can be run with the included software ISIM. The following modelling topics are covered in this chapter: biological reactor, activated sludge treatment processes, fixed film reactors, nitrification of waste water, primary treatment of waste water, tertiary water treatment processes, sludge disposal, biodegradation, anaerobic digestion processes, anaerobic fixed film processes, microbial interaction kinetics, ecological population studies, river and stream modelling lake and reservoir modelling, land pollution modelling, insecticides in an aquatic ecosystem, the Gala World and a structured growth of white cabbage. The book is a well presented and well written textbook in the field of modelling in environmental technology, particularly covering waste water treatment. The detailed presentation of many useful sub models is easily understood by the readers. The treatment of lake and stream models for instance is more limited and gives only a first coarse overview of these topics. The book gives some references to other models and modelling book, but the overall use of references is too limited. The book contains many clearly presented examples. It is a highly recommendable textbook in modelling in environmental technology. Sven Erik J~rgensen DFH, Institute A, Environmental Chemistry University Park 2 2100 Copenhagen O Denmark
Detecting Ecological Impacts, Concepts and Applications in Coastal Habitats, edited by Russel J. Schmitt and Craig W. Osenberg. Academic Press, San Diego, New York, Boston, London, Sidney, Tokyo and Toronto, 1996. Hardbound, 401 pages. The volume focuses on ecological impacts on coastal habitats caused by human activities. The topic is covered by 18 chapters with different authors. The editors have, however, achieved to pro-
