A Special Publication of the Society of Environmental Toxicology and Chemistry (SETAC) Aquatic Mesocosm Studies in Ecological Risk Assessment discusses the methods currently used for conducting simulated field studies and provides a series of case histories in which mesocosm type studies have been used to assess the impact of pesticides on aquatic ecosystems. Specific chapters address the dosing and exposure components of such studies and how they influence experimental design. Advantages and disadvantages of various statistical designs are addressed in detail. Regulatory aspects of the design and interpretation of these studies are also covered. The book will be a superb reference for aquatic biologists, ecologists, toxicologists, environmental toxicologists, environmental chemists, and regulatory personnel.

"A first-rate anthropological study of Hinduism. . . . The scholarship is clearly of superior quality. There is no study with the [same] kind of comprehensive breadth and treatment.Robert Levy and Kedar Rajopadhyaya show us how to do anthropology at this time in our history."--Triloki N. Pandey, University of California, Santa Cruz "I have no doubt that Mesocosm will become a classic in South Asian anthropology and Indology--leaving aside its implications for our understanding of other traditional cities in ancient European and Middle Eastern as well as more recent Oriental civilizations. . . . A very welcome and clear ordering of the very detailed and complex material."--Michael Witzel, Harvard University

Techniques developed for enclosing viable natural planktonic ecosystems pro vided the opportunity for prolonged and detailed investigation of dynamic events within the pelagic system of a known water body. Recent investigations into plankton ecology, using enclosure systems in dif ferent marine environments, are discussed in relation to the data obtained from the Nanaimo, British Columbia, Canada, plastic-sphere experiments of 1960 and 1962. Three types of modern enclosure experiments are recognized: floating systems within nutrient levels maintained or running down, and benthic attached systems. The review largely discusses results from the two kinds of floating systems. Processes at several trophic levels have been investigated in enclosures. This review attempts to draw together details from all experimental systems to emphasize the enclosures' contribution to our understanding of planktonic systems. Enclosures made it possible to examine primary production processes, particularly in relation to inorganic nutrient availability and water-column sta bility. Recent experiments have used the understanding of these processes as a management technique in maintaining different planktonic systems. Relation ships between primary and secondary trophic levels are not always easy to inter pret, since the growth of primary carnivore populations can often determine the survival of zooplankton populations. Nevertheless, the development of co horts of herbivorous zooplankton has been followed in several enclosures, yield ing useful information on development times and production rates. In enclosed systems it is thus possible to directly relate tertiary level production to inorganic nutrient input, and to calculate production rates and exchange efficiencies at several trophic levels.

Agroecosystems in a Changing Climate considers the consequences of changes in the atmosphere and climate on the integrity, stability, and productivity of agroecosystems. The book adopts a novel approach by bringing together theoretical contributions from ecologists and the applied interpretations of agriculturalists. Drawing these two approa

The ocean helps moderate climate change thanks to its considerable capacity to store CO2, through the combined actions of ocean physics, chemistry, and biology. This storage capacity limits the amount of human-released CO2 remaining in the atmosphere. As CO2 reacts with seawater, it generates dramatic changes in carbonate chemistry, including decreases in pH and carbonate ions and an increase in bicarbonate ions. The consequences of this overall process, known as "ocean acidification", are raising concerns for the biological, ecological, and biogeochemical health of the world's oceans, as well as for the potential societal implications. This research level text is the first to synthesize the very latest understanding of the consequences of ocean acidification, with the intention of informing both future research agendas and marine management policy. A prestigious list of authors has been assembled, among them the coordinators of major national and international projects on ocean acidification.

The volumes 3/I and 3/J present a modern account of polycyclic aromatic hydrocarbons (PAHs) and their heterocyclic analogs in the environment. The authors are internationally well recognized scientists belonging to those working presently in the frontline of the different subfields of this interdisciplinary area of environmental science; they give an integrated thorough overview on this hot topic. Extensive cross-referencing between chapters provides the readers with an easy access to all major areas. Due to the huge amount of material the text is published in two volumes (3/I and 3/J). It is expected that both volumes will soon become a major source of information and inspiration for all researchers actively working in PAH environmental chemistry or ecology.
