This new edition of Guide to Process Based Modeling of Lakes and Coastal Seas brings the modeling up to date, taking into account multiple stressors acting on aquatic systems. The combination of acidification and increasing amounts of anoxic waters associated with eutrophication puts severe stress on the marine environment. The detection and attribution of anthropogenic changes in coastal seas are therefore crucial and transparent modeling tools are increasingly important. Modeling the marine CO2–O2 system makes systematic studies on climate change and eutrophication possible and is fundamental for understanding the Earth system. This second edition also includes new sections on detection and attribution and on modeling future changes, as well as improved exercises, updated software, and datasets. This unique book will stimulate students and researchers to develop their modeling skills and make model codes and data transparent to other research groups. It uses the general equation solver PROBE to introduce process-oriented numerical modeling and to build understanding of the subject step by step. The equation solver has been used in many applications, particularly in Sweden and Finland with their numerous lakes, archipelago seas, fjords, and coastal zones. It has also been used for process studies in the Polar Seas and the Mediterranean Sea and the approach is suitable for applications in many other environmental applications. Guide to Process Based Modeling of Lakes and Coastal Seas: • is a unique teaching tool for systematic learning of aquatic modeling; • approaches lake and ocean modeling from a new angle; • introduces aquatic numerical modeling using a process-based approach; • enables the thorough understanding of the physics and biogeochemistry of lakes and coastal seas; • provides software, datasets, and algorithms needed to reproduce all calculations and results in the book; • provides a number of creative and stimulating exercises with solutions; • addresses the interaction between climate change and eutrophication and is a good basis for learning Earth System Sciences.
This volume contains studies on the evolution and function of lightweight constructions of planktonic and other organisms, and examples of how they can be used to create new solutions for radical innovations of lightweight constructions for technological application. The principles and underlying processes responsible for evolution and biodiversity of marine plankton organisms are highly relevant and largely unresolved issues in the field of marine science. Amongst the most promising objects for the study of evolution of stable lightweight constructions are marine organisms such as diatoms or radiolarians. Research in these fields requires interdisciplinary expertises such as in evolutionary modelling, paleontology, lightweight optimization, functional morphology, and marine ecology. Considerable effort and expert knowledge in production engineering or lightweight optimization is necessary to transfer knowledge on biogenic structures and evolutionary principles into new lightweight solutions. This book show methods and examples of how this can be achieved efficiently.
Written by a leading expert in the field, this volume provides an
outstanding review of the potential effects of global warming on
river flows and water resources.
This book reviews the research in various fields of oceanography on the responses of the East Japan Sea to climate change. The uniqueness of the East Japan Sea comes from the rapid and amplified response to climate change, which includes long-terms trends of physical and chemical parameters at a rate that almost doubles or even higher the global rate. This book aims to provide in an organized way the results from the previously published knowledge but also to introduce an updated view of the research recently carried out. The book is divided into several parts that comprise the physical, chemical, biological, and geological aspects of the region and fisheries. This book is made for researchers and students working on climate variability as well as for the oceanography community working on world's marginal seas. The research presented in this work will also benefit to researchers from other fields such as social scientists and environmentalists, and also policy makers.
This book uses resource economics costing approaches incorporating externalities to estimate the returns for the country's irrigation and demonstrates how underestimating the cost of water leads farmers to overestimate profits. The importance of the subject can be judged in light of the fact that India is the largest user of groundwater both for irrigation and for drinking purposes, pumping twice as much as the United States and six times as much as Europe. Despite water's vital role in ensuring economic security for the nation and farmers alike by supporting more than 70% of food production, water resource economists are yet to impress upon farmers and policymakers the true value of water and the urgent need for its sustainable extraction, recharge and use. In an endeavor to promote more awareness, the book further delineates the roles of the demand side and supply side in the economics of irrigation, and explains how the cost of water varies with the efforts to recharge it, crop patterns, degrees of initial and premature well failure and degrees of externalities. It also discusses the importance of micro-irrigation in the economics of saving water for irrigation, estimating the marginal productivity of water and how it improves with drip irrigation, the economics of water sharing and water markets, optimal control theory in sustainable extraction of water, payment of ecosystem services for water and how India can effectively recover. In closing, the book highlights the role of socioeconomic and hydrogeological factors in the economics of irrigation, which vary considerably across hard rock areas and the resulting limitations on generalizing.
This book documents the current state of research by Chinese scientists on fish biology and fisheries and brings together manuscripts by authors from research institutions, universities and government agencies. There are papers on aquaculture, life history, genetics, marine and freshwater biology, conservation, physiology, new species descriptions, and truly amazing hypogean fishes. The information on these remarkable cave species shows how much we have yet to learn from that incredible fauna. There are papers dealing with some of the largest fishes and some of the smallest cave species. There are papers dealing with some of the most traditional forms of aquaculture and others with the most modern molecular techniques. The volume includes papers on critically threatened native fishes as well as the most common food species, such as grass carp (Ctenopharyngodon idella). The information on rare and threatened species shows how China is dealing with their endangered fishes. The information on their carp species will be invaluable to those in other countries who will either take advantage of the productive carp species in aquaculture or try to manage them as invasive species outside China. For the first time we bring together a complete overview of the state of fisheries research in China.
This extensive work focuses on an important group of temperate freshwater fish, approaching the topic from the perspectives of both biology and aquaculture. It compiles the latest research on fish belonging to the Percidae family and describes in detail all biological aspects relevant to the culture of different species, including ecology, reproductive physiology, feeding and nutrition, genetics, immunology, stress physiology and behavior. It also considers commercial fish production and fish farming topics, such as protocols for induction of gonad maturation, spawning, incubation and larval rearing. Expert contributors not only provide a critical peer review of scientific literature but also original research data, and identify effective practical techniques. The book features chapters on systematics, ecology and evolution, on development, metabolism and husbandry of early life stages and on growth, metabolism, behavior and husbandry of juvenile and grow-out stages. Furthermore, the authors consider genetic improvement and domestication, as well as diseases and health management, crucial to the readers' understanding of these fish and how they can be cultured. Both researchers of percid fish biology and aquaculture professionals who are considering intensive and pond culture of percid fishes will value this timely and comprehensive handbook.)
The book mainly introduces readers to the development and current status of water quality criteria (WQC) in China and other countries or areas, and proposes a minimum toxicity data requirement (MTDR; i.e., six species from three phyla) as the principle metric for deriving WQC in China. Further, ten model species from 4 different phyla are recommended as domestic test species, and the methodologies for deriving aquatic life criteria, sediment criteria, ecocriteria and nutrient criteria in China are also described in detail. In order to demonstrate the methods, several representative chemical pollutants and aquatic environments are highlighted as examples. The book provides important references for future WQC-related research in China, which will make it of great interest to researchers and graduate students in the fields of environmental science, ecology and aquatic science etc.

Following from Fish for Life - Interactive Governance for Fisheries (Kooiman et al., 2005), which presents an interdisciplinary and intersectoral approach to the governance of capture and aquaculture fisheries, this volume pursues what interactive governance theory and the governability perspective contribute to the resolution of key fisheries problems, these include overfishing, unemployment and poverty, food insecurity, and social injustice. Since these problems are varied and can be felt among governments, resource users and communities globally, the diagnosis must be holistic, and take account of principles, institutions, and operational conditions. The authors argue that 'wicked problems' and institutional limitations are inherent to each setting, and must be included in the analysis. The volume thereby offers a new lens and a systematic approach for analysing the nature of problems and challenges concerning the governance of fisheries, explores where these problems are situated, and how potential solutions may be found. "It now seems clear that the crisis in the world's fisheries [is] a much larger and more complex problem than many had imagined. Yet, examining it through the lens of governability may offer the best hope for alleviating it--as well as alleviating similar crises in other social systems." James R. McGoodwin (Professor Emeritus, University of Colorado)
Microalgae are one of the most studied potential sources of biofuels and bioenergy.

Greenhouse gas and techno-economic modelling are reviewed as is the 100 year history of microalgae as sources of biofuels and of commercial-scale microalgae culture. A summary of relevant basic standard methods used in the study of microalgae culture is provided. The book is intended for the expert and those starting work in the field.
This book is an integrated approach to present a detailed case study in order to address the taxonomic and ecological features of this planktonic choreotrich protists in an iconic tropical mangrove wetland - Sundarban. To identify each tintinnid species, emphasis is given with regards to taxonomic features accompanied by high resolution images. This work explores the interaction between man-induced stress and the impact of climate change which is threatening the tintinnid biodiversity, and suggests, for example, remedial measures by adopting sound management strategies. Tintinnids (Protozoa: Ciliata: Tintinnida) are a coherent group ecologically recognized as micro-zooplankton. They deserve special attention because of their unique biodiversity and their crucial, functional role in the marine food chain. This is a valuable reference source for students, researchers, policy planners and coastal managers engaged in the field of marine biology, microbial ecology and marine bio-resources.
Whatever theory may be advanced to explain diurnal migration, the underlying reactions involved must be demonstrated conc- sively in the laboratory before the explanation can be ?nally accepted George L. Clarke 1933 p. 434 In oceans and lakes, zooplankton often make diel vertical migrations (DVM), descending at dawn and coming up again in late afternoon and evening. The small animals cover distances of 10-40 m in lakes or even a few hundred metres in the open oceans. Although not as spectacular as migrations of birds or the massive movements of large mammals over the African savannas, the numbers involved are very large and the biomass exceed the bulk of the African herds. For example, in the Antarctic oceans swarms of "Krill" may cover kilometres across, with thousands of individuals per cubic metre. These Euphausiids are food for whales, the most bulky animals on earth. Zooplankton are key species in the pelagic food web, intermediary between algae and ?sh, and thus essential for the functioning of the pelagic community. Prey for many, they have evolved diverse strategies of survival and DVM is the most imp- tant one. Most ?sh are visually hunting predators and need a high light intensity to detect the often transparent animals. By moving down, the well-lit surface layers are avoided but they have to come up again at night to feed on algae.
One of the major questions in the evolution of animals is the transition from unicellular to multicellular organization, which resulted in the emergence of Metazoa through a hypothetical Urmetazoa. The Comparative Embryology of Sponges contains abundant original and literary data on comparative embryology and morphology of the Porifera (Sponges), a group of 'lower Metazoa'. On the basis of this material, original typization of the development of Sponges is given and the problems concerning origin and evolution of Porifera and their ontogenesis are discussed. A morphogenetic interpretation of the body plan development during embryogenesis, metamorphosis and asexual reproduction in Sponges is proposed. Special attention is given to the analysis of characteristic features of the ontogenesis in Porifera. The book pursues three primary goals: 1) generalization of all existing information on individual development of sponges, its classification and a statement according to taxonomical structure of Porifera; 2) revealing of heterogeneity of morphogenesis and peculiarities of ontogeneses in various clades of Porifera, and also their correlations with the organization, both adult sponges, and their larvae; 3) revealing homology of morphogeneses in both Porifera and Eumetazoa, testifying to the general evolutionary roots of multicellular animals, and peculiar features of sponges' morphogeneses and ontogenesis. This book will be of interest to embryologists, zoologists, morphologists and researchers in evolutionary biology.
Originally published in 1987, this book describes and discusses the vegetation of rivers and other watercourses in Europe with an emphasis upon distributional, community and historical ecology. It was firmly based upon many years of field investigations carried out by the author in various countries in the European Economic Community. The main purpose of the text was to increase the understanding of river vegetation in relation to the varying physical characteristics of the watercourses. The rivers of the EEC are considered in detail, with an emphasis upon the influences of landscape, geology, climate, settlement patterns, water use and management and pollution. This book will be of value to anyone with an interest in river botany.
A multidisciplinary study of the Bera Lake is presented here, focusing on natural resources throughout the lake s catchment area and assessing environmental impact. This applied limnology study examines issues relating to land development including soil erosion and nutrient loss in the catchment area, severe pollution of water, sediment resources in open waters and wetlands, and reduction of aquatic and bird populations. The chapters provide a comprehensive view of problems, risks and possible mitigation measures associated withthis great natural habitat in Malaysia. The book highlights the technology and methods used to estimate both soil erosion rate and nutrient loss from the lake catchment, including an explanation of the measurement of sedimentation rate in Bera Lake, using 137Cs and 210Pb radioisotopes. The author examines the current and historic situation of contamination in sediments, presents an ecological risk assessment and finally describes a master management plan, proposing practices to mitigate the environmental impacts of existing agricultural projects and practices to control future projects. Readers will learn of a decrease in the watershed supply of water to the Bera Lake, of shoaling, degradation of water and sediment quality and the extinction of several kinds of flora and fauna. This volume also offers an approach to sustainable land use, with regard to natural resources conservation."
Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 192."Antarctic Subglacial Aquatic Environments" is the first volume on this important and fascinating subject. With its underlying theme of bridging existing knowledge to future research, it is a benchmark in the history of subglacial lake exploration and study, containing up-to-date discussions about the history and background of subglacial aquatic environments and future exploration. The main topics addressed are identification, location, physiography, and hydrology of 387 subglacial lakes; protocols for environmental stewardship and protection of subglacial lake environments; details of three programs aiming to explore Vostok Subglacial Lake, Ellsworth Subglacial Lake, and Whillans Subglacial Lake over the next 3-5 years; assessment of technological requirements for exploration programs based on best practices for environmental stewardship and scientific success; and knowledge of subglacial lakes as habitats for microbial life and as recorders of past climate and ice sheet change. Its uniqueness, breadth, and inclusiveness will appeal to microbiologists and those interested in life in extreme environments, paleoclimatologists and those interested in sedimentary records of past changes, glaciologists striving to understand how water beneath glaciers affects their flow, and those engaged in developing technology to undertake direct measurement and sampling of extreme environments on Earth and in the solar system.
As our society places increasing importance on the management of our natural resources, natural resource managers in both public and private sectors will need to understand the essential elements of soil and water systems. The principles of soil and water systems are clearly presented, and examples are given to demonstrate the applications to typical problems encountered by resource managers. Also includes the basic principles for controlling water and wind erosion, the disposal of excess water in humid areas and from irrigation systems, and the management of irrigation systems.
A colorful look at a forgotten era of Florida tourism. Filled with rare photographs, vintage postcards and advertisements, and fascinating writing from over 100 years ago, Florida's Healing Waters spotlights a little-known time in Florida history when tourists poured into the state in search of good health. Rick Kilby explores the Victorian belief that water caused healing and rehabilitation, tracing the history of "taking the waters" from its origins in the era of Enlightenment. Nineteenth-century Americans traveled from afar to bathe in the outdoors and soak up the warm climate of Florida. Here, with more than 1,000 freshwater springs, 1,300 miles of coastline, and 30,000 lakes, water was an abundant resource. Through the wealth of images in this book, Kilby shows how Florida's natural wonders were promoted and developed as restorative destinations for America's emerging upper class. The rapid growth in tourism infrastructure that began during the Gilded Age lasted well into the twentieth century, and Kilby explains how these now-lost resorts helped boost the economy of modern Florida. Today, these splendid health spas and elaborate bathing facilities have been lost, replaced by recreational amenities for a culture more about sun and fun than physical renewal. In this book, Kilby emphasizes the value of honoring and preserving the natural features of the state in the face of continual development. He reminds us that Florida's water is still a life-giving treasure.
Dynamic programming is a method of solving multi-stage problems in which decisions at one stage become the conditions governing the succeeding stages. It can be applied to the management of water reservoirs, allowing them to be operated more efficiently. This is one of the few books dedicated solely to dynamic programming techniques used in reservoir management. It presents the applicability of these techniques and their limits on the operational analysis of reservoir systems. The dynamic programming models presented in this book have been applied to reservoir systems all over the world, helping the reader to appreciate the applicability and limits of these models. The book also includes a model for the operation of a reservoir during an emergency situation. This volume will be a valuable reference to researchers in hydrology, water resources and engineering, as well as professionals in reservoir management.
"Rivers and Society" explores the ways in which human/river relations have shaped important historical transformation processes. With examples ranging from explorations of classical agrarian civilizations such as the Indus, Angkor and Maya, to analyses of the role of water in the modernization process of countries such as Spain, Britain and Japan, the international contributors shed new light on the ways in which the key relationship between humans and water has given rise to new forms of social organization, new technologies and economic activities
First published in 1987, this book examines the numerous interacting physical, chemical and biological processes which regulate the acidity of freshwaters. Natural acidification processes are considered first, the the effects of acidifying pollutant inputs from the atmosphere and of other human activities. The relative importance of the different processes is critically examined. Concepts incorporated are drawn from chemistry, physics, geology, hydrology, plant science and forestry, soil science, microbiology and meteorology. The authors have attempted to thread the relevant information together to make a coherent story which should be understandable and useful to readers from a number of disciplines: undergraduates and postgraduates studying environmental science, ecology, water quality and hydrogeochemistry; politicians and managers concerned with pollution control. Indeed, most of the text should be understandable to well-informed non-scientists who want (or need) a better grasp of this fascinating and important topic. |
