Freshwater eels are almost infinitely improbable creatures. They spawn and die in the middle of the ocean, often associated with undersea mountains. Their tra- parent, leaf-like larvae move with ocean currents for months or years until they approach the mouths of freshwater rivers. Then they undergo a dramatic transf- mation in morphology, physiology and behavior. They move from their planktonic oceanic environment, migrate upstream and live for several years as apex fre- water predators. Then, almost impossibly, as they become sexually mature, they reverse their migration downstream to the ocean and back to spawning grounds to complete their life cycle. The dramatic changes in their life cycles are incredible. The efforts to unravel the details of their life history have been truly daunting. Much of the past research was the work of dedicated individuals who devoted their lifetime research to these fishes. Freshwater eels merit a separate chapter in almost any textbook dealing with ichthyology, marine biology or animal migration. We know a great deal about some aspects of the biology of freshwater eels. However, our understanding of their bi- ogy still resembles a work of art as much as a work of science. To some it appears like the sweeping brush strokes of a Japanese Zen landscape, to others it resembles the work of a French impressionist, and to still others it appears as magic realism.

This book presents the most comprehensive model yet for describing the structure and functioning of running freshwater ecosystems. This "riverine ecosystem synthesis" (RES) is a result of combining several theories published in recent decades, dealing with aquatic and terrestrial systems. New analyses are fused with a variety of new perspectives on how river network ecosystems are structured and function, and how they change along longitudinal, lateral, and temporal dimensions. Among these novel perspectives is a dramatically new view of the role of hydrogeomorphic forces in forming functional process zones from headwaters to the mouths of great rivers.
Designed as a useful tool for aquatic scientists worldwide whether they work on small streams or great rivers and in forested or semi-arid regions, this book will provide a means for scientists to understand the fundamental and applied aspects of rivers in general and includes a practical guide and protocols for analyzing individual rivers. This combination of theoretical and applied analysis is quite unique in running freshwater ecology. Specific examples of rivers in at least four continents (Africa, Australia, Europe and North America) serve to illustrate the power and utility of the RES concept.
- Develops the classic, seminal article in River Research and Applications, "A Model of Biocomplexity in River Networks Across Space and Time" which introduced the RES concept for the first time
- Provides a guide to the practical analysis of individual rivers using the Riverine Ecosystems Synthesis and extends its use from pristine ecosystems to modern, human-modified rivers.
- An essential aid both to the study fundamentaland applied aspects of rivers, such as rehabilitation, management, monitoring, assessment, and flow manipulation of river networks.

The goal of the book is to examine scientific advances since 2000 that may have increased understanding and options in three general areas related to hypoxia:

Characterization the Cause(s) of Hypoxia. The physical, biological and chemical processes that affect the development, persistence and extent of hypoxia in the northern Gulf of Mexico.

Characterization of Nutrient Fate, Transport and Sources. Nutrient loadings, fate, transport and sources in the Mississippi River that impact Gulf Hypoxia.

Scientific Basis for Goals and Management Options. The scientific basis for, and recommended revisions to, the goals proposed in the Action Plan; and the scientific basis for the efficacy of recommended management actions to reduce nutrient flux from point and nonpoint sources.

In addressing the state of the science, the book focuses on the strengths and limitations of the science in managing the Gulf hypoxia problem, including available data, models and model results and uncertainty. It includes work from the following authors:

This volume offers a comprehensive history of the Mount Desert Island Biological Laboratory (MDIBL), one of the major marine laboratories in the United States and a leader in using marine organisms to study fundamental physiological concepts. Beginning with its founding as the Harpswell Laboratory of Tufts University in 1898, David H. Evans follows its evolution from a teaching facility to a research center for distinguished renal and epithelial physiologists. He also describes how it became the site of major advances in cytokinesis, regeneration, cardiac and vascular physiology, hepatic physiology, endocrinology and toxicology, as well as studies of the comparative physiology of marine organisms. Fundamental physiological concepts in the context of the discoveries made at the MDIBL are explained and the social and administrative history of this renowned facility is described.

The subjects refer to histories of ancient and modern use of seacoasts; possible macro-projects capable of massive changes in the coastlines of the Dead Sea, Red Sea and Persian Gulf caused by canal and massively scaled hydropower dam installations; relevant macro-projects for the Black Sea and Baltic Sea; possibilities of refreshment of the Aral Sea and Iran 's Lake Uremia with seawater or river freshwater importation macro-projects; potential rehabilitation of some vital arid zone regions now dominated by moving or movable surface granular materials using unique and unusual macro-projects; seawater flooding of land regions situated below present-day global sea-level; harnessing energy and obtaining freshwater from the world 's salt-laden ocean by modern industrial means; various macro-projects designed specifically for the protection (reduction of vulnerability) of particular Earth geographical regions.

Tidal freshwater forested wetlands are unique wetland systems. Occupying low relief coastal areas which are subject to both upland runoff and tidal flooding, these systems are especially vulnerable to pressure from human development and to climate change impacts of sea-level rise and increased drought/flood frequency. Yet to date the ecological dynamics, distribution, and conservation status of these communities is poorly understood.This book draws together the latest findings from investigators focusing on the hydrological processes, community organization, and stress physiology of freshwater, tidally influenced land-margin forests of the southeastern United States. It describes the land use history that led to the restricted distribution of these wetlands, and provides descriptions of the hydrology, soils, biogeochemistry, and physiological ecology of these systems, highlighting the similarities shared among tidal freshwater forested wetlands.

Radioecology in Northern Euroepean Seas summarizes an extensive body of literature on the oceanographic and biological conditions involved in the transfer and accumulation of radionuclides in marine sediment and biota of the Northern European seas. Much of the information has been derived through many decades of investigation carried out by the Murmansk Marine Biological Institute. This book presents the original works, augmented and complemented by work conducted by other institutes during the nuclear era. The synthesis of this extensive body of information forms the basis of a new methodological and theoretical framework describing radionuclide bioaccumulation by marine invertebrate and vertebrate animals, paying special attention to marine food webs leading to humans.

Lake Issyk-Kul is a closed lake located in the Tien Shan mountain belt of the Republic of Kyrgyzstan. It is the world's fifth deepest lake (668 m) and the second largest high altitude lake in the world (1607 m above sea level). The lake is affected by several environmental threats of both anthropogenic and natural origin: decline of the lake level resulting in progressively increasing salinity, incomplete vertical water exchange, and risk of contamination by past and present industrial activity.
Although the lake has been intensively studied, the information is only available in unpublished reports or local scientific journals. This book presents for the first time to an international audience the main physical, chemical, biological and geological characteristics of the lake, the fruits of many years of observations, complemented by recent results of international projects. Case studies of similar problems in other parts of the world are presented, together with ethical aspects of the environmental protection of the lake.

Life began in the sea, and even today most of the deep diversity of the planet is marine. This is often forgotten, especially in tropical countries like Costa Rica, renowned for their rain forests and the multitude of life forms found therein. Thus this book focusing on marine diversity of Costa Rica is particularly welcome. How many marine species are there in Costa Rica? The authors report a total of 6,777 species, or 3. 5% of the world's total. Yet the vast majority of marine species have yet to be formally described. Recent estimates of the numbers of species on coral reefs range from 1-9 million, so that the true number of marine species in Costa Rica is certainly far higher. In some groups the numbers are likely to be vastly higher because to date they have been so little studied. Only one species of nematode is reported, despite the fact that it has been said that nematodes are the most diverse of all marine groups. In better studied groups such as mollusks and crustaceans, reported numbers are in the thousands, but even in these groups many species remain to be described. Indeed the task of describing marine species is daunting - if there really are about 9 million marine species and Costa Rica has 3. 5% of them, then the total number would be over 300,000. Clearly, so much remains to be done that new approaches are needed. Genetic methods have en- mous promise in this regard.

Conservation Physiology for the Anthropocene: A Systems Approach, Volume 39A in the Fish Physiology series, is a comprehensive synthesis on the physiology of fish in the Anthropocene. This volume closes the knowledge gap by considering the many ways in which different physiological systems (e.g., sensory physiology, endocrine, cardio-respiratory, bioenergetics, water and ionic balance and homeostasis, locomotion/biomechanics, gene function) and physiological diversity are relevant to management and conservation. As the world is changing, with a dire need to identify solutions to the many environmental problems facing wild fish populations, this book comprehensively covers conservation physiology and its future techniques. Conservation physiology reveals the many ways in which environmental change and human activities can negatively influence wild fish populations. These tactics inform new management and conservation activities and help create the necessary conditions for fish to thrive.

Advances in Algal Biology: A Commemoration of the Work of Rex Lowe was written by students and colleagues of Rex Lowe to acknowledge his esteemed career that included exceptional contributions to research and teaching. Papers in the book cover a variety of topics in algal ecology, focusing on benthic algal ecology in freshwater ecosystems. The studies provide an unusual combination of small-scale experiments and large-scale regional surveys that bridge both basic and applied ecology. Ecologists, limnologists, phycologists, and environmental scientists will find valuable contributions to the development and application of algal research.

The book provides acoustic images about sedimentary systems of the shelf edge, slope and deep-sea-floor. The knowledge gained can be used by both academia and hydrocarbon industry in a better understanding of continental margins and the processes shaping them. It is also of interest to colleagues in earth sciences involved in margin surveys for environmental studies. The current global trend in marine resource development is to move into deeper water, and this book can provide examples relevant to other passive margins around the world.

All over the world, sustainable river basin management is a leading principle of policy plans and legal instruments for water management (e.g. the European Water Framework Directive). The evidence, however, to underpin the full scope of sustainability is rather scanty. In this book an integrative perspective on trends and challenges in river science and management is demonstrated. The three pillars underneath sustainable water management, ecology, economy and sociology, are elaborated by experts in their fields. A number of papers integrate the current knowledge on the structure, functioning and management of 'living rivers'. The book includes data and experiences concerning the rivers Allier, Meuse, Rhine, Sava and Tagliamento in Europe and the river Illinois in the USA. Sustainable river basin management asks for un-orthodox rehabilitation programmes and ecosystem based and transboundary management approaches.

Coral Reef Fishes is the successor of "The Ecology of Fishes on Coral Reefs." This new edition includes provocative reviews covering the major areas of reef fish ecology. Concerns about the future health of coral reefs, and recognition that reefs and their fishes are economically important components of the coastal oceans of many tropical nations, have led to enormous growth in research directed at reef fishes. Coral Reef Fishes is much more than a simple revision of the earlier volume; it is a companion that supports and extends the earlier work. The included syntheses provide readers with the current highlights in this exciting science.
Key Features
* An up-to-date review of key research areas in reef fish ecology, with a bibliography including hundreds of citations, most from the last decade
* Authoritative, up-to-date, provocative chapters written to suggest future research priorities
* An important companion and successor to "The Ecology of Fishes on Coral Reefs"
* Includes discussions of regulation of fish populations, dispersal or site fidelity of larval reef fishes, sensory and motor capabilities of reef fish larvae, and complexities of management of reef species and communities

Ascidians are the invertebrate group that gave rise to vertebrates, thus the biology of ascidians provides an essential key to understanding both invertebrates and vertebrates. This book is the first to cover all areas of ascidian biology, including development, evolution, biologically active substances, heavy metal accumulation, asexual reproduction, self-defense mechanisms, neuroscience, allorecognition mechanisms, comparative immunology, taxonomy, ecology, genome science, and food science. The more than 65 articles that make up the collection were contributed by leading ascidiologists from Europe, North America, and Asia who participated in the First International Symposium on the Biology of Ascidians, held in June 2000 in Sapporo, Japan. For scientists and students alike, the book is an invaluable source of information from the latest, most comprehensive studies of ascidian biology.

Despite their importance in sustaining livelihoods for many people living along some of the world's most populous coastlines, tropical mangrove forests are disappearing at an alarming rate. Occupying a crucial place between land and sea, these tidal ecosystems provide a valuable ecological and economic resource as important nursery grounds and breeding sites for many organisms, and as a renewable source of wood and traditional foods and medicines. Perhaps most importantly, they are accumulation sites for sediment, contaminants, carbon and nutrients, and offer significant protection against coastal erosion. This book presents a functional overview of mangrove forest ecosystems; how they live and grow at the edge of tropical seas, how they play a critical role along most of the world's tropical coasts, and how their future might look in a world affected by climate change. Such a process-oriented approach is necessary in order to further understand the role of these dynamic forests in ecosystem function, and as a first step towards developing adequate strategies for their conservation and sustainable use and management. The book will provide a valuable resource for researchers in mangrove ecology as well as reference for resource managers.

The limnological study of Toolik Lake began in the Summer of 1975. This research was an outgrowth of the arctic IBP project which had focused mainly on small Arctic pond ecosystems on the Alaskan Arctic coastal plain. It was thought desirable to study larger, deeper lakes which contained fish to further generalizations developed during the IBP study. Initial research on Toolik Lake and the surrounding lakes and ponds focused on process studies such as annual primary productivity of the lake or the vertical migration patterns of the resident zooplankton. In 1983 the philosophy of the research changed with the funding of a more integrated programmer. The fundamental question posed was whether Arctic lake and stream ecosystems are regulated from the bottom up by nutrient availability or from the top down by the density and activity of top predators. In 1987 the Toolik Lake area was designated an LTER (Long-Term Ecological Research) site, one of 18 such sites throughout the United States, Puerto Rico, and the Antarctic. The research theme for the Arctic LTER also focuses on the regulation of Arctic ecosystems, whether regulation comes from the top down or bottom up. The Arctic LTER also incorporates a terrestrial component as well as a lake and stream component.

This 8-volume set provides a systematic description on 8,350 active marine natural products from 3,025 various kinds of marine organisms. The diversity of structures, biological resources and pharmacological activities are discussed in detail. Molecular structural classification system with 264 structural types are developed as well. The 3rd volume mainly illustrates the molecular formula and structures of alkaloids. .

Do real stem cells and stem cell lineages exist in lower organisms? Can stem cells from one organism parasitize the soma and/or the germ line of conspecifics? Can differentiated cells in marine organisms be re-programmed to regenerate tissues, organs and appendages through novel de-differentiation, transdifferentiation, or re-differentiation processes, leading to virtually all three germ layers, including the germline? The positive answers to above questions open a new avenue in stem cell research: the biology of stem cells in marine organisms. It is therefore unfortunate that while the literature on stem cell from terrestrial organisms is rich and expanding at an exponential rate, investigations on marine organisms stem cells are very limited and scarce.

By presenting theoretical chapters, overview essays and specific research results, this book summarises the knowledge and the hypotheses on stem cells in marine organisms through major phyla and specific model organisms. The study on stem cells from marine invertebrates may shed lights on mechanisms promoting immunity, developmental biology, regeneration and budding processes in marine invertebrates, body maintenance, aging and senescence. It aims in encouraging a larger scientific community to follow and study the novel phenomena of stem cells behaviours as depicted from the few currently studied marine invertebrates.
