Enclosed ecosystem experiments have gained in popularity as research tools in ecological science, particularly in the study of coastal aquatic environments. These systems provide scientists with a degree of experimental control that is not achievable through field experiments. Yet to date, techniques for systematically extrapolating results from small-scale experimental ecosystems to larger, deeper, more open, more biologically diverse, and more heterogeneous ecosystems in nature have not been well developed. Likewise, researchers have lacked methods for comparing and extrapolating information among natural ecosystems that differ in scale. Enclosed Experimental Ecosystems and Scale: Tools for Understanding and Managing Coastal Ecosystems provides scientists, managers, and policy makers with an introduction to what has been termed the "problem of scale", and presents information that will allow for improved design and interpretation of enclosed experimental aquatic ecosystems. The book integrates the results of a 10-year research project involving a multi-disciplinary team of scientists and students to explore scale-related questions in a variety of coastal habitats. Anticipating use as a reference, the book has been designed so that individual sections and individual pages can function as stand alone units.

Multiphoton ionization of atoms in intense laser-light fields is gaining ground as a spectroscopic diagnostic tool. In this volume, Delone and Krainov present their and others' theoretical descriptions of the processes occurring in atoms under conditions of multiple-photon impacts, in particular, the shift, broadening, and mixing of electronic states, which complicate the interpretation of spectra. The intended audience is the experimental physicist or physical chemist facing the task of unraveling an atomic multiphoton ionization spectrum. Comparisons of the theory to available experimental data are provided throughout. The topics of individual chapters include tunneling ionization, above-threshold ionization, ionization of multiply charged ions, resonance-enhanced ionization, super-intense radiation fields, and properties of Rydberg states in strong fields.

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.

"How can we increase the production and harvest of living marine resources in the new millennium? Bridging potentials and environmental constraints". This was the theme of the 1st Maricult Conference arranged in Trondheim, Norway in June 2000 in connection with termination of the Norwegian research programme Maricult (1996-2000; www.maricult.org). The intention for the conference was not only to present a state of the art overview of the research conducted as part of the programme, but also to describe other experiences and to discuss the ideas and the scientific status of the programme with the international scientific community. A total of 50 oral communications and 8 posters were presented at the conference. Sixteen of them are included in the present volume. They deal with such topics as strategies for improving marine harvest, underlying mechanisms for marine productivity, new concepts of mariculture with emphasize on mussels, and nutrient supply and environmental impact.

Seascape Ecology provides a comprehensive look at the state-of-the-science in the application of landscape ecology to the seas and provides guidance for future research priorities. The first book devoted exclusively to this rapidly emerging and increasingly important discipline, it is comprised of contributions from researchers at the forefront of seascape ecology working around the world. It presents the principles, concepts, methodology, and techniques informing seascape ecology and reports on the latest developments in the application of the approach to marine ecology and management. A growing number of marine scientists, geographers, and marine managers are asking questions about the marine environment that are best addressed with a landscape ecology perspective. Seascape Ecology represents the first serious effort to fill the gap in the literature on the subject. Key topics and features of interest include: The origins and history of seascape ecology and various approaches to spatial patterning in the sea The links between seascape patterns and ecological processes, with special attention paid to the roles played by seagrasses and salt marshes and animal movements through seascapes Human influences on seascape ecology—includes models for assessing human-seascape interactions A special epilogue in which three eminent scientists who have been instrumental in shaping the course of landscape ecology offer their insights and perspectives Seascape Ecology is a must-read for researchers and professionals in an array of disciplines, including marine biology, environmental science, geosciences, marine and coastal management, and environmental protection. It is also an excellent supplementary text for university courses in those fields.
