Volume 25 of this authoritative review series continues the high standard set by the editors in the past. Marine biologists everywhere have come to value and enjoy the wide variety of thought-provoking papers written by invited experts. In this volume are reviews of four animal groups which span the entire range of the marine food chain. The role of parasites in ecology is a growing interest and the parasites of zooplankton are described in detail for the first time. Aspects of thegastropods, cephalopods and fish life are also examined in detail.

The application of mesocosms, defined in this report as artificial 3 3 experimental enclosures ranging in size from 1 m to 10m , to address various problems in the marine sciences has been a relatively recent development. The application of the technology was dictated by the realization that many important ocean processes and interactions cannot be fully understood from observations in the natural environment or in smaller enclosures. Such studies involve, for example, determining the interactions between, and energy transfer from, one trophic level to another, the biogeochemical cycling of elements and compounds, etc. These and similar interactions and rate processes cannot normally be established in situations (nature) where the detection and quantification of rate processes are confused by advection and/or the inability to study the same populations over time. In the case of microcosms, mixed populations of primary producers, consumers, and carnivores cannot be maintained, in balance, for a sufficient length of time to determine normal interactions between the various components of these trophic levels. This report, prepared by SCOR Working Group 85, critically examines past applications of mesocosms to ocean research, though there is no attempt to comprehensively review all literature relevant to the subject. Further, the report outlines some important advances emanating from their use and provides recommendations for future applications. It constitutes the first of two reports from the Working Group (see Introduction).

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.
