Book Description
This is the first comprehensive book on Tropical Freshwater Zooplankton. It covers the whole spectrum of Tropical Freshwater zooplankton and includes the non conventional group, the Ostracoda. One chapter is devoted to miscellaneous groups like Chaoborus, Hydracarina, Protozoa and some others that occur from time to time in freshwater zooplankton. Another chapter, on the interactions of zooplankton and fisheries, should make the book more useful to tropical fish culturists and fishery biologists. The authors of the chapters on the different groups of zooplankton and fisheries are authorities in these fields They have also collaborated with the leading researchers in the field from all continents and this work has benefited from input of both younger scientists and senior collaborators working closely with the authors in laboratories worldwide. The text is written clearly and concisely in as simple a way as the material permits, so that it can be used by workers who are not specialists in zooplankton, and in developing countries. However, the material is comprehensive, authoritative and up to date. The book is profusely illustrated with 121 plates (1119 line drawings) and should enable users to obtain reliable diagnoses to species level in many cases and also glean basic ideas about methodology, ecology, zoogeography and classification. The book, though written by six authors, is completely integrated as a guide to Tropical Freshwater Zooplankton. This book should be of use to a wide variety of freshwater biologists, both beginners and those already working in the field for some time. There is much material that is relevant and up to date, some of it that is not familiar to many students in the field. The literature coverage is designed to give a wide perspective of research in the field without attempting to be exhaustive. Key references are included so that the user can access almost all the literature in the field but with special reference to the tropical region. This book should be on the shelf of individual workers in zooplankton and especially in laboratories where work on freshwater ecology and sytematics of the fauna is being carried out. Libraries should have a copy available as a general reference for freshwater biologists. Researchers and students of freshwater zooplankton, fishery scientists and fish culturists in tropical regions will benefit from this wide-ranging book.

Book Description
Our knowledge of the limnology of the waters situated, roughly, between the tropics of cancer and of capricorn, has depended for a long time on the expedition-approach, and therefore developed in a rather irregular, haphazard way, with the personal incentive of a small number of individuals as the main driving force. Things slowly started to change in the 1950s, and at an accelerating rate in the 1960s and 1970s. The IBP, and later the SCOPE and MAB programs, whatever their shortcomings are or may have been, promoted in-depth research of a small number of tropical lakes. For one thing, they showed the need for the creation of in situ limnological research institutes. When, in the 1970s, limnological research facilities or their nuclei began to appear in the tropical zones of all continents, an interesting phenomenon occurred: while most of the young native limnologists had received their training in advanced centres or courses held in the temperate (and developed) climatic zones, quite a few of their former supervisors or their associates became interested in warm lakes and rivers as well, using the new or newly expanded local institutes. We are, today, still in this phase and it is, apparently, expanding even further. Although not all experiments of this kind lead to happy marriages, a few were quite successful, and several papers contained in the present volume are hoped to reflect this.

Book Description
This volume reports on the findings of experts on tropical zooplankton gathered at a meeting in Kariba, Zimbabwe, in 1991. Some basic questions were asked on community composition and biodiversity in the tropics versus the non-tropics. Old ideas on the nature of zooplankton, which were found to be wider than the `classical' rotifers, cladocerans and copepods, as well as on the number of species in tropical waters, are now beginning to break down accordingly as more and more blank spots in the tropics are explored and as more in-depth studies on the zooplankton of tropical lakes are becoming available. This volume contains a mix of papers discussing the two alternative controls (bottom-up and top-down) of zooplankton community structure and these constitute another step towards a coherent theory of tropical ecosystem theory.

Book Description
Fundamentals of Tropical Freshwater Wetlands: From Ecology to Conservation Management is a practical guide and important tool for practitioners and educators interested in the ecology, conservation and management of wetlands in tropical/subtropical regions. The book is written in such a way that, in addition to scientists and managers, it is accessible to non-specialist readers. Organized into three themed sections and twenty-three chapters, this volume covers a variety of topics, exposing the reader to a full range of scientific, conservation and management issues. Each chapter has been written by specialists in the topic being presented. The book recognizes that wetland conservation, science and management are interlinked disciplines, and so it attempts to combine several perspectives to highlight the interdependence between the various professions that deal with issues in these environments. Within each chapter extensive cross-referencing is included, so as to help the reader link related aspects of the issues being discussed. Contributed to by global experts in the field of tropical wetlands Includes case studies and worked examples, enabling the reader to recreate the work already done Focuses on tropical systems not available in any other book

Book Description
Tropical Radioecology is a guide to the wide range of scientific practices and principles of this multidisciplinary field. It brings together past and present studies in the tropical and subtropical areas of the planet, highlighting the unique aspects of tropical systems. Until recently, radioecological models for tropical environments have depended upon data derived from temperate environments, despite the differences of these regions in terms of biota and abiotic conditions. Since radioactivity can be used to trace environmental processes in humans and other biota, this book offers examples of studies in which radiotracers have been used to assess biokinetics in tropical biota. This book: Features chapters co-authored by world experts that explain the origins, inputs, distributions, behaviour, and consequences of radioactivity in tropical and subtropical systems. Provides comprehensive lists of relevant data and identifies current knowledge gaps to allow for targeted radioecological research in the future. Integrates radioecological information into the most recent radiological consequences modelling and best-practice probabilistic ecological risk analysis methodology, given the need to understand the implications of enhanced socio-economic development in the world's tropical regions. John Twining has published research and conducted field and laboratory studies on the nuclear industry's impact on the environment over four decades. While much of this work has been related to Australia's role as a uranium supplier, he has also evaluated this impact at the Maralinga test sites in the deserts of central Australia and the effects of French testing in the central Pacific. John also focused on the uptake of radionuclides by crops and the use of isotopes as tracers of biological processes. Much of this work was accomplished in tropical or subtropical environments, and this experience proved valuable for Tropical Radioecology. John is now associate editor for the Journal of Environmental Radioecology and a self-employed consultant radioecologist.

Book Description
Healthy waterways and oceans are essential for our increasingly urbanised world. Yet monitoring water quality in aquatic environments is a challenge, as it varies from hour to hour due to stormwater and currents. Being at the base of the aquatic food web and present in huge numbers, plankton are strongly influenced by changes in environment and provide an indication of water quality integrated over days and weeks. Plankton are the aquatic version of a canary in a coal mine. They are also vital for our existence, providing not only food for fish, seabirds, seals and sharks, but producing oxygen, cycling nutrients, processing pollutants, and removing carbon dioxide from our atmosphere. This Second Edition of Plankton is a fully updated introduction to the biology, ecology and identification of plankton and their use in monitoring water quality. It includes expanded, illustrated descriptions of all major groups of freshwater, coastal and marine phytoplankton and zooplankton and a new chapter on teaching science using plankton. Best practice methods for plankton sampling and monitoring programs are presented using case studies, along with explanations of how to analyse and interpret sampling data. Plankton is an invaluable reference for teachers and students, environmental managers, ecologists, estuary and catchment management committees, and coastal engineers.

Book Description
Freshwater Biodiversity is a much underestimated component of global biodiversity, both in its diversity and in its potential to act as models for fundamental research in evolutionary biology and ecosystem studies. Freshwater organisms also reflect quality of water bodies and can thus be used to monitor changes in ecosystem health. The present book comprises a unique collection of primary research papers spanning a wide range of topics in aquatic biodiversity studies, and including a first global assessment of specific diversity of freshwater animals. The book also presents a section on the interaction between scientists and science policy managers. A target opinion paper lists priorities in aquatic biodiversity research for the next decade and several reactions from distinguished scientists discuss the relevance of these items from different points of view: fundamental ecology, taxonomy and systematics, needs of developing countries, present-day biodiversity policy at European and at global scales. It is believed that such a platform for the interaction between science and science policy is an absolute necessity for the efficient use of research budgets in the future.

Book Description
This work provides a user-friendly, species level taxonomic key based on morphology, current nomenclature, and modern taxonomy using molecular tools which fulfill the most pressing needs of both researchers and environmental managers. This key arms the reader with the tools necessary to improve their species identification abilities. This book resolves another issue as well: the mix of female and male characters used in keys to the calanoid copepods. Often, during the identification process, both calanoid copepod sexes are not available, and the user of such a key is stuck with an uncertain identification. Here, separate male and female keys to the calanoid copepods are provided for both the genera and species levels.
