This landmark publication takes the 50th anniversary of the publication of the seminal paper by the Danish scientist, Einer Steemann Nielsen, as an occasion to assess the development, present state and future of the major aspects in freshwater and marine plankton productivity. Each chapter of this important work has been written by internationally-acknowledged experts in the subject, and the whole has been carefully drawn together and edited to provide a book that is an essential tool and reference for all aquatic scientists.The book takes ascending temporal and spatial size scale as its framework - covering molecular to geological scales. Chapters include reviews of physiology and biochemistry, measurement of phytoplankton productivity, the supply and uptake of nutrients, variability in processes and production, the evolution of the carbon cycle, and ecosystems. The subject is set in context with a chapter covering the work of Steemann Nielsen, whose work inspired the last 50 years of aquatic productivity studies. Historical aspects are discussed together with thought-provoking assessments of modern technological approaches and where future research emphasis should be focussed.Phytoplankton Productivity provides, in one book, cutting edge reviews and key facts on the subject, making it a vital information source for marine and freshwater biologists, oceanographers, ecologists, environmental scientists and plant scientists. Copies should also be available in libraries of any research establishment and university as a reference for students, wherever these subjects are studied and taught.Also available from Blackwell PublishingAquatic PhotosynthesisP.

This volume gives an insight into what a group of contemporary plankton biologists think about the utility, virtues, strengths and theoretical and practical weaknesses of J.H. Connell's "Intermediate Distrubance Hypothesis" within the context of phytoplankton ecology. The sequence of papers in this volume moves from particular case studies to more general and finally theoretical approaches.

The ecology of potamoplankton has received less attention than lake plankton. These proceedings produce a synthesis of the composition, community structure and dynamics of lotic phytoplankton, which are intuitively submitted to a strong physical control in the flowing environment, perceived as much more "disturbed" than a lake, even than a well-mixed shallow one. It turns out that the boundary between the phytoplankton of rivers and lakes is not as clear-cut as was thought. In particular, most contributions provide arguments emphasizing the prominent role of physical control in both aquatic systems, especially due to the steep light gradient resulting from turbulent mixing in a turbid water column. Similarities and differences between potamoplankton and limnoplankton, largely based on the information gathered by the contributors are discussed in the introductory paper by Reynolds et al.

If the trends of the late 20th century continue, most climatologists agree that the concentration of carbon dioxide in the atmosphere will have doubled by 2050. This increase in CO2 will have a major effect on the global climate and substantially alter the physical, chemical and biological characteristics of lakes throughout the world. A number of studies have considered the impact of climate change on water resources, but many have a national focus and are primarily concerned with changes in water quantity rather than quality. In recent years a number of workers have demonstrated that year-to-year changes in the weather have a profound impact on the seasonal dynamics of lakes. This book highlights some of the mechanisms involved and assesses the likely qualitative impact of changes in the weather.

These proceedings deal with the relationship between species composition of freshwater phytoplankton and the trophic gradient. Particular regard is paid to the composite question, what lives where and why? Overview papers report the state-of-the-art and suggest that the trophic spectrum appears to be a probabilistic outcome of several dimensions of variability that impinge upon phytoplankton species selection. Studies on community structure span all latitudes from those of Antarctica to equatorial Brazil, and also include reports on light and nutrient gradients, pH and fish-stock effects on species composition. Seasonal and longterm phytoplankton dynamics in lakes of varying trophic status are also considered. Finally, studies on the taxonomy and autoecology of some groups (e.g. Volvocales, Chrysophytes and Euglenophytes) living at the extremes of the trophic spectrum contribute to our knowledge of this usually neglected phytoplankton. This text should prove a good source of information to anyone working on phytoplankton ecology and ecological indicators.

These proceedings of a workshop of the International Association for Phytoplankton Taxonomy and Ecology are directed specifically at the relationship between phytoplankton ecology and the trophic status of water bodies. Contributions address the fact that distinctive assemblages of phytoplankton species are closely associated with particular categories of water bodies. Particular attention is paid to how communities are assembled and to the ways in which environmental constraints filter the successful species. Overview articles are included. The text should be a useful source of information to limnologists, algologists, and the technical staff of all water suppliers.

This is the first time that a book covers such a topic, and it will prove an excellent source of information to anyone working on phytoplankton ecology and ecological indicators.Limnologists in general, algologists and the technical staff at water authorities will all benefit by reading this book.
