Biological Effects of Surfactants
Offering a new perspective on the hazards of pollution, Biological Effects of Surfactants examines the effects of anionic, non-ionic, cationic surfactants, and detergents on a wide range of organisms, populations, communities, and ecosystems. The author establishes new quantitative characteristics of the effects and presents study results on newly discovered phenomena. While proposing and substantiating new priorities and approaches for testing, assessing, and characterizing the biological activities and hazards of substances, the book illustrates how the data obtained can be used to develop effective environmental remediation and protection measures to improve water quality.
Rotifera X
This volume reflects the latest developments in the research of a global community of rotifer researchers, who came together at Illmitz, Austria in 2003. Contributions are manifold and span fields from phylogeny and evolution of the phylum Rotifera to practical aspects of aquaculture and ecotoxicology. Major issues include phylogeny and evolution, genetics and molecular ecology, new aspects of rotifer anatomy through the application of confocal laser-scanning microscopy, anhydrobiosis, long-term studies in lakes and rivers, population dynamics and community ecology, trophic relationships between copepods and rotifers, alongside biodiversity studies based on classical taxonomic concepts and molecular approaches. Although primarily focussed on one taxonomic group, the scientific outcome of this meeting is of relevance to the study of other aquatic microinvertebrates as well.
Sustainable Utopias
To reclaim a sense of hope for the future, German activists in the late twentieth century engaged ordinary citizens in innovative projects that resisted alienation and disenfranchisement. By most accounts, the twentieth century was not kind to utopian thought. The violence of two world wars, Cold War anxieties, and a widespread sense of crisis after the 1973 global oil shock appeared to doom dreams of a better world. The eventual victory of capitalism and, seemingly, liberal democracy relieved some fears but exchanged them for complacency and cynicism. Not, however, in West Germany. Jennifer Allen showcases grassroots activism of the 1980s and 1990s that envisioned a radically different soci...
Evolutionary Ecology of Freshwater Animals
Evolutionary ecology includes aspects of community structure, trophic interactions, life-history tactics, and reproductive modes, analyzed from an evolutionary perspective. Freshwater environments often impose spatial structure on populations, e.g. within large lakes or among habitat patches, facilitating genetic and phenotypic divergence. Traditionally, freshwater systems have featured prominently in ecological research and population biology. This book brings together information on diverse freshwater taxa, with a mix of critical review, synthesis, and case studies. Using examples from bryozoans, rotifers, cladocerans, molluscs, teleosts and others, the authors cover current conceptual issues of evolutionary ecology in considerable depth. The book can serve as a source of critically evaluated ideas, detailed case studies, and open problems in the field of evolutionary ecology. It is recommended for students and researchers in ecology, limnology, population biology, and evolutionary biology.
Dividuations
This book offers an epistemological critique of the concept of the individual and of individuality. It argues that because of our bio(techno)logical entanglements with non-human others, billions of microorganisms and our multiple (in)voluntary participations in socio(techno)logical processes, we have to conceive of ourselves no longer as individuals, but as dividuations. This dividual character which enforces simultaneous and multidirectional participations in different spheres is also apt for other living beings, for entities such as the nation state, for single cultures, production processes and works of art. The critique of individuality in the book is also elaborated in critical re-readings of classical philosophical texts from Plato up to today; the new concept of dividuation is a modified and semantically enriched version of certain concepts of the French philosophers Gilbert Simondon and Gilles Deleuze.

Rotifer Symposium V
The Fifth International Rotifer Symposium was organized by Dr. Claudia Ricci and held in the northern Italian town of Gargnano (Brescia) from September 12-17, 1988. Through the generosity of the Rector of Milano University, a beautiful villa on the shores of Lake Garda was made available to the 83 people from 20 countries who attended the symposium. Ten of these rotifer workers had attended the four previous meetings. Such symposia serve three major functions, the results of which will be apparent in the papers contained in this volume. First, because of the heterogeneity of interests and absence of concurrent sessions, the attendees are exposed to an unusually large variety of research prob...
Cyanotoxins
Toxic cyanobacteria are increasingly recognised as a potential hazard in water for human use. The recent availability of methods for quantitative screening is leading to a surge of research on their occurrence. This book presents a novel compilation of extensive screening results showing the cyanotoxin levels that may be expected when certain taxa dominate. These results indicate cyanotoxins to be the most widespread among the chemicals of concern in water used for drinking and recreation. It further combines field data with results from laboratory culture experiments to suggest a unifying view of how environmental factors control the cyanotoxin levels in natural waters. A practical section is dedicated to the exposure of humans through drinking-water and recreation.
