Evidence now suggests that the roles of essential fatty acids as growth promoters and as indices of health and nutrition are fundamentally similar in freshwater and marine ecosystems. Lipids in Aquatic Ecosystems integrates this divergent literature into a coordinated, digestible form.

Chapters are organized so as to discuss and synthesize the flow of lipids from lower to higher trophic levels, up to and including humans. Linkages between the production, distribution and pathways of these essential compounds within the various levels of the aquatic food webs, and their ultimate uptake by humans and other terrestrial organisms, are highlighted throughout the book. This book will be of interest to researchers and resource managers working with aquatic ecosystems.

This book explores the nature of marine conservation based on the case study of Hinase, a fishing village in Okayama, Japan. It focuses on the fishers' self-motivated eelgrass restoration activity which has been continued for more than 30 years. This activity in Hinase recently attracted international attention as a case under the name "Satoumi" and "Marine Protected Areas" in several governmental reports, but detailed information, such as the historical background and social structure of Hinase, has not yet been analyzed. This book, therefore, fulfills this gap by providing its ethnographic information. In addition, this book offers some points for critical thinking by concluding that marine conservation activities cannot always be evaluated or arranged under the standardized approach with limited time and space. This viewpoint reaffirms the importance of local initiative and highlights the value of qualitative research to seek the way forward for promising marine conservation. This book is suitable for an academic audience in the field of social sciences, such as applied anthropology, as well as ecologists, government officials, environmentalists, and citizens who are interested or engaged in environmental issues or natural resource management.

Diminishing water resources are becoming of increasing concern because in many countries the sources of drinking water are close to being exhausted. Therefore, there is an urgent need to study and assess the various components of global water resources, of which freshwater lakes are one of the most important. This book discusses contemporary limnological problems on a local, regional and global scale with special emphasis on the application of remote-sensing techniques to monitor lake dynamics, thermodynamics, biodynamics and water quality. An interactive approach is used to assess various processes from both the numerical modelling and observational standpoints. The authors recommend a combined use of in situ and remote-sensing data, giving a specific comparative analysis of the lakes of north-western Russia and the American Great Lakes as an illustration. The role of GIS is discussed and emphasised.

Planktonic marine cyanobacteria are abundant and significant in the biogeochemistry of the sea. This volume focuses on the filamentous cyanobacteria, particularly those in the genus Trichodesmium which are common in tropical and subtropical seas. A portion of this book also concerns bloom-forming cyanobacteria in the Baltic Sea area. Filamentous cyanobacteria are important as primary producers and for the fixation of atmospheric nitrogen and thus are significant in global cycling of both of these elements. In recent years, through the application of new techniques and intensive multi-disciplinary research programs, progress has been made in understanding both the biology of these cyanobacteria and their place in the marine food web. A broad range of topics is covered in this book, ranging from molecular biology, physiology, ultrastructure, enzyme localization, toxicology, remote sensing, buoyancy, herbivory and the ecology of these organisms in the marine food web. This volume is an outgrowth of a NATO-sponsored meeting held in May 1991 in Bamberg, Germany, and represents the latest synthesis on these marine phytoplankters.

The presence of water on Earth is discussed in this book using various theories about its origin as a basis. These theories include a massive degassing of the primitive parent bodies that built our planet as well as a late addition from comets that collided with the Earth s surface. The extraordinary physico-chemical properties of the water molecules, combined with its abundance and distribution over the Earth s surface, have contributed to regulating the global climate and favoring species evolution for more than 4 billion years. The early emergence of life in the deep ocean and its further diversification were closely linked to the global water cycle whose dynamics result from the energy balance between solar radiation and the internal heat flux of the Earth. Chapter 1 of this book deals with the extraordinary physico-chemical properties of the water molecule while Chapter 2 provides insight on theories regarding the origin of water on Earth. In the third chapter, the author focuses on the chemical composition of the main water reservoirs of our planet. Chapters 4 and 5 discuss water s relationship with plate tectonics and life, respectively. The sixth and final chapter uses stable isotope tracking to look into the water cycle and past climates. Contents 1. Water: A Molecule Endowed with Extraordinary Physicochemical Properties. 2. Theories about the Origin of Water on Earth. 3. The Main Water Reservoirs on Earth and their Chemical Composition. 4. Water and Plate Tectonics. 5. Water and Life. 6. Stable Isotope Tracking: Water Cycles and Climates of the Past.

Intertidal mudflats are distinct, highly-productive marine habitats which provide important ecosystem services to the land-sea interface. In contrast to other marine habitats, and despite a large body of primary scientific literature, no comprehensive synthesis exists, such that the scattered knowledge base lacks an integrated conceptual framework. We attempt to provide this synthesis by pulling together and contextualizing the different disciplines, tools, and approaches used in the study of intertidal mudflats. The editor pays particular attention to relationships between the various components of the synthesis, both at the conceptual and the operational levels, validating these relationships through close interaction with the various authors.

Lough Neagh is the largest lake in the British Isles. It covers an area of 383 km2 being 30 km along its longest axis. From pre-historic times the lake and its rivers influenced the settlements of man in the role of a fishery and communication link with the interior of Ireland. Ireland's first canal, completed in 1787, linked the small but significant coal deposits of Tyrone to Dublin by way of the lough and later the Lagen Canal became an important commercial route to the new city of Belfast. Today, only sand barge transport persists but the lough supports Europe's largest eel fishery and provides commercial salmon, trout and perch catches, besides acting as an important centre for recreational pursuits. Increasingly it has become the major water resource for Northern Ireland supplying much of the demand for the heavily populated Belfast area. Biologically the lough is rich, sustaining enormous invertebrate populations of, for example, chironomids and gammarids alongside the comparatively exotic glacial relict, Mysis relicta. Its bird life makes the lough an area of very special conservation interest as a Ramsar site. The book describes the basic ecology of the lough with particular emphasis on both the interaction of the physical, chemical and biological components and the role of ecology in resource management. Extensive recent researches are set in geological, geographical and historical context and together with palaeolimnological studies of the sediments are used to trace major changes in the ecology of the lough under man's influence, especially in the past 100 years.

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.

Humic substances occur in all kinds of aquatic systems, but are particularly important in northern, coniferous areas. They strongly modify the aquatic ecosystems and also constitute a major problem in the drinking water supply.This volume covers all aspects of aquatic humic substances, from their origin and chemical properties, their effects on light and nutrient regimes and biogeochemical cycling, to their role regarding organisms, productivity and food web organization from bacteria to fish. Special emphasis is paid to carbon cycling and food web organization in humic lakes, but aspects of marine carbon cycling related to humus are treated as well.

This book highlights the potential advantages of using marine invertebrates like tunicates, echinoderms, sponges and cephalopods as models in both biological and medical research. Bioactive compounds found in marine organisms possess antibacterial, antifungal, anti-diabetic and anti-inflammatory properties, and can affect the immune and nervous systems. Despite substantial research on the medicinal attributes of various marine invertebrates, they are still very much underrepresented in scientific literature: the majority of cell, developmental and evolutionary scientific journals only publish research conducted on a few well-known model systems like Drosophila melanogaster or Xenopus laevis. Addressing that gap, this book introduces readers to new model organisms like starfish or nemertera. By showing their benefits with regard to regeneration, stem cell research and Evo-Devo, the authors provide a cross-sectional view encompassing various disciplines of biological research. As such, this book will not only appeal to scientists currently working on marine organisms, but will also inspire future generations to pursue research of their own.

Hemiptera - Heteroptera encompasses the three well-defined suborders of the true bugs which are adapted to an aquatic or littoral habitat. The book begins with a section on the biology these insects and provides illustrations of the basic features of their morphology and outlines the larval development. Brief outlines of the ecological and zoogeographical peculiarities of the three aquatic suborders are presented individually, and various methods for observing, collecting, preserving, rearing, and examining specimens are discussed.

Most of the book is devoted to keys for the identification of adults to species, and notes are provided that will help recognize the known larvae. Unlike most other aquatic insects, the larval instars of the heteropteran species closely resemble the adults in their morphology, preferred habitats, and feeding habits. Therefore, distinguishing features of those relatively few larvae which have been described in detail are usually mentioned in the keys to the adults rather than being included in separate keys. In addition to the most important features for determining the individual species, many keys include additional notes on the morphology, which is intended to give the user a better chance of recognizing specimens of species not yet known to science. After the currently recognized name of each species, the known range is provided. Regions of the world outside of South America, South American countries, and the states of Brazil from which the species has been reported are listed. Following the range information, major synonyms previously used for the species in the literature are provided. If subspecies have been described and are still recognized as such, they are also discussed. Finally, if the status of the species is regarded as uncertain because of a poor description, strong resemblance to another species, or any other reason, a note is added that a detailed study will be necessary to clarify the status of the taxon. Taxonomic revisions in the book itself are strictly avoided.

To provide the user of the keys with maximum assistance in making reliable identifications, the book is richly illustrated with pen and ink drawings of thousands of individual morphological structures arranged in 820 figures. The book is intended to make a significant impact toward popularizing the study of South American water bugs by assembling and condensing the information in hundreds of individual publications on the group, which appeared in many books and journals published in many different countries over the past 200 years. Some of these works are very difficult to obtain in South America, and their lack creates serious impediments to systematic, ecological, and zoogeographical research. In the more than 730 titles appearing in the bibliography, the original descriptions and revisions of almost all South American species can be found.
