Download or read book Fish Physiology Hypoxia written by Jeffrey G. Richards and published by Academic Press. This book was released on 2009-03-10 with total page 549 pages. Available in PDF, EPUB and Kindle. Book excerpt: Periods of environmental hypoxia (Low Oxygen Availability) are extremely common in aquatic systems due to both natural causes such as diurnal oscillations in algal respiration, seasonal flooding, stratification, under ice cover in lakes, and isolation of densely vegetated water bodies, as well as more recent anthropogenic causes (e.g. eutrophication). In view of this, it is perhaps not surprising that among all vertebrates, fish boast the largest number of hypoxia tolerant species; hypoxia has clearly played an important role in shaping the evolution of many unique adaptive strategies. These unique adaptive strategies either allow fish to maintain function at low oxygen levels, thus extending hypoxia tolerance limits, or permit them to defend against the metabolic consequences of oxygen levels that fall below a threshold where metabolic functions cannot be maintained. The aim of this volume is two-fold. First, this book will review and synthesize the adaptive behavioural, morphological, physiological, biochemical, and molecular strategies used by fish to survive hypoxia exposure and place them within an environmental and ecological context. Second, through the development of a synthesis chapter this book will serve as the cornerstone for directing future research into the effects of hypoxia exposures on fish physiology and biochemistry. - The only single volume available to provide an in-depth discussion of the adaptations and responses of fish to environmental hypoxia - Reviews and synthesizes the adaptive behavioural, morphological, physiological, biochemical, and molecular strategies used by fish to survive hypoxia exposure - Includes discussion of the evolutionary and ecological consequences of hypoxia exposure in fish

Download or read book Real time Coastal Observing Systems for Marine Ecosystem Dynamics and Harmful Algal Blooms written by Babin, Marcel and published by UNESCO. This book was released on 2008-06-05 with total page 880 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proliferation of harmful phytoplankton in marine ecosystems can cause massive fish kills, contaminate seafood with toxins, impact local and regional economies and dramatically affect ecological balance. Real-time observations are essential for effective short-term operational forecasting, but observation and modelling systems are still being developed. This volume provides guidance for developing real-time and near real-time sensing systems for observing and predicting plankton dynamics, including harmful algal blooms, in coastal waters. The underlying theory is explained and current trends in research and monitoring are discussed.Topics covered include: coastal ecosystems and dynamics of harmful algal blooms; theory and practical applications of in situ and remotely sensed optical detection of microalgal distributions and composition; theory and practical applications of in situ biological and chemical sensors for targeted species and toxin detection; integrated observing systems and platforms for detection; diagnostic and predictive modelling of ecosystems and harmful algal blooms, including data assimilation techniques; observational needs for the public and government; and future directions for research and operations.

Download or read book Algae and their Biotechnological Potential written by Feng Chen and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Algae are important organisms that include seaweeds and a number of single-celled and multicellular microscopic forms. Algae are ubiquitous; they inhabit almost everywhere including oceans, freshwater bodies, rocks, soils, and trees. Man's uses of algae may date back to ancient times. In recent decades, there has been renewed interest in the utilization of algae as sources of health food and high-value chemicals and pharmaceuticals, and for aquaculture, agriculture, and wastewater treatment. Nevertheless, the biotechnological potential of algae is still far from fully exploited, due to a lack of understanding of algal characteristics and culture systems, as well as of advanced research techniques. This book contains selected papers presented at the Fourth Asia-Pacific Conference on Algal Biotechnology held in Hong Kong, on 3-6 July, 2000. Written by experts in the field, this book provides a state-of-the-art account of algal biotechnology research. Topics range from use of algae in agriculture to environmental monitoring and protection, from algal culture systems to production of high-value chemicals and pharmaceuticals by algae, and from algal product purification to gene transformation and regulations. This book is intended for use by researchers and industrialists in the field of algal biotechnology. It will also be an important reference for undergraduate and postgraduate students in biotechnology and food science, as well as in biology in general.

Book excerpt: Freshwater Microbiology: Perspectives of Bacterial Dynamics in Lake Ecosystems provides a comprehensive and systematic analysis of microbial ecology in lakes. It offers basic information on how well the bacterial community composition varies along the spatio-temporal and trophic gradients along with the evaluation of the bioindicator species of bacteria so as to act as a key to predict the trophic status of lake ecosystems. The book helps to identify the factors of potential importance in structuring the bacterial communities in lakes as it delves into the dynamics and diversity of bacterial community composition in relation to various water quality parameters. It helps to identify the possibility of bioremediation plans and devising future policy decisions, with better conservation and management practices. - Provides a comprehensive and systematic analysis of microbial ecology - Helps to identify the factors of potential importance in structuring the bacterial community composition - Gives insight into the bacterial diversity of freshwater lake ecosystems along with their industrial potential - Caters to the needs and aspirations of students and professional researchers

Download or read book Eutrophication causes consequences and control written by Abid A. Ansari and published by Springer Science & Business Media. This book was released on 2010-10-17 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eutrophication continues to be a major global challenge to water quality scientists. The global demand on water resources due to population increases, economic development, and emerging energy development schemes has created new environmental challenges to global sustainability. Eutrophication, causes, consequences, and control provides a current account of many important aspects of the processes of natural and accelerated eutrophication in major aquatic ecosystems around the world. The connections between accelerated eutrophication and climate change, chemical contamination of surface waters, and major environmental and ecological impacts on aquatic ecosystems are discussed. Water quality changes typical of eutrophication events in major climate zones including temperate, tropical, subtropical, and arid regions are included along with current approaches to treat and control increased eutrophication around the world. The book provides many useful new insights to address the challenges of global increases in eutrophication and the increasing threats to biodiversity and water quality.

Download or read book Eutrophication in Coastal Ecosystems written by Jesper H. Andersen and published by Springer. This book was released on 2012-03-14 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coastal eutrophication has been and still remains an important issue for the scientific community. Despite many efforts to mitigate coastal eutrophication, the problems associated with eutrophication are still far from being solved. This book focusses on the most recent scientific results in relation to specific eutrophication issues, e.g. definition(s) and causes; nutrient loads, cycling and limitation; reference conditions, primary effects and secondary effects; trend reversal (oligotrophication), as well as links to other pressures (climate change and top/down control). It also focusses on monitoring and modelling of coastal eutrophication, and adaptive and science-based nutrient management strategies. The book is based on selected papers from the Second International Symposium on Research and Management of Eutrophication in Coastal Ecosystems, held 20-23 June 2006 in Nyborg, Denmark.
