Book excerpt: 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 excerpt: 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 Synopsis A Guide to Tropical Freshwater Zooplankton by : C. H. Fernando

Download or read book A Guide to Tropical Freshwater Zooplankton written by C. H. Fernando. This book was released on 2002. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Zooplankton Community Analysis by : W.M. Jr. Lewis

Download or read book Zooplankton Community Analysis written by W.M. Jr. Lewis. This book was released on 2012-12-06. Available in PDF, EPUB and Kindle. Book excerpt: This book is based on the premise that the study of ecological communities should be a composite analysis of system properties (community structure, community energetics) and population properties (life history patterns, adaptive strategies) backed by a thorough understanding of the physical chemical environment. Too frequently community ecology takes a much narrower focus. This may partly be the result of perceived antagonisms between schools of thought in ecology. Despite their rather separate origins, the multiple theoretical and methodological tools that now exist must be applied synthetically to real communities if the progress of the past two decades is to continue into the next two. This book has a case history format, which increases the opportunity for detailed analysis, although I have attempted to maintain the general per spective of a community ecologist and to draw extensively from the literature whenever it seems profitable to do so. The case history data are for Lake Lanao, a large tropical lake. The main zooplankton data base used in the analysis is entirely original and unpublished, although the detailed support ing data on the physical-chemical environment and the phytoplankton com munity have been presented in numerous journal articles and are thus abstracted or used selectively to meet the needs of zooplankton community analysis.

Book Synopsis Zooplankton by : George Kehayias

Download or read book Zooplankton written by George Kehayias. This book was released on 2014. Available in PDF, EPUB and Kindle. Book excerpt: Zooplankton organisms comprise very important elements of the structure and function of marine and freshwater ecosystems, not only as consumers of primary production, but also as food items for juvenile stages of several fish species. Moreover, its sensitivity to both man-made and natural changes makes zooplankton quite suitable for assessing alterations in the trophic dynamics and the ecological state of aquatic ecosystems related to changes in nutrient loading and climate. Multi-scale, spatial and temporal relationships between zooplankton variability and environmental heterogeneity are still not satisfactorily understood due to the complexity of the different aquatic ecosystems (considering both biotic and abiotic elements). Thus, the ambition of the present edition is to contribute to the understanding of the role of zooplankton by investigating ecological aspects such as the species diversity, their spatial distribution and seasonal dynamics in relation to the environmental influence in various aquatic ecosystems around the world. Topics discussed in this book include the understanding of the role of zooplankton in the transfer of pollutants through trophic food webs; plankton models to explain red tides; spatial patterns of trophy and zooplankton communities in a tropical urban reservoir; the zooplankton variation in five Greek lakes; the zooplankton community in a nuclear power station cooling reservoir; the spatio-temporal dynamics of cladocera and copepoda in the Danube River; the gelatinous zooplankton in the Namibian upwelling region; and the zooplankton community in relation to the environmental factors in a solar saltern.
