Book Description
Freshwater algae are among the most diverse and ubiquitous organisms on earth. They occupy an enormous range of ecological conditions from lakes and rivers to acidic peat swamps, inland saline lakes, snow and ice, damp soils, wetlands, desert soils, wastewater treatment plants, and are symbionts in and on many plants, fungi, and animals. In North America, the variety of freshwater habitats colonized by algae is very rich, and offers an enormous and fascinating range of environments for their study. They form the base of most aquatic food webs and are critical to studies of ecosystem health. Algal ecologists and taxonomists play an important role in the understanding of aquatic ecosystems: their biodiversity, productivity, interactions with other organisms, and water quality. This book provides in one volume a practical and comprehensive guide to the genera of freshwater algae known from North America. The format combines the necessary ecological, taxonomic and methodological information for all scientists working in aquatic environments, whether their specialty is in environmental monitoring and water quality assessment, biological composition, ecology, evolution, or molecular biology. Key Features * The first complete accounting of North America's freshwater algal genera in more than 50 years * Includes a guide to the current literature on species identification in each group of algae * High-quality photographs and drawings of more than 770 genera * A clear, easy-to-use introductory key to the diagnostic chapters * Synthetic chapters on freshwater habitats, use of algae in environmental assessment, and control of nuisance algae * Contributions from 27 experts in all areas of freshwater algae * Extensive literature citations * Companion volume of Ecology and Classification of North American Freshwater Invertebrates 2nd edition, edited by Throp and Covich

Book Description
Acting as titans in global control of the biosphere and colonizing virtually all corners of the earth, algae, extremely diverse and numerous oxygenic, photosynthetic organisms, can be major players in and drivers of environmental change. For hundreds of years, since their evolutionary origins by endosymbiosis, when a protozoan enslaved a cyanobacte

Book Description
Availability of and adequate accessibility to freshwater and energy are two key technological and scientific problems of global significance. At the end of the 20th century, the deficit of water for human consumption and economic application forced us to focus on rational use of resources. Increasing the use of renewable energy sources and improving energy efficiency is a challenge for the 21st century. Geothermal energy is heat energy generated and stored in the Earth, accumulated in hydrothermal systems or in dry rocks within the Earth’s crust, in amounts which constitute the energy resources. The sustainable management of geothermal energy resources should be geared towards optimization of energy recovery, but also towards rational management of water resources since geothermal water serves both as energy carrier and also as valuable raw material. Geothermal waters, depending on their hydrogeothermal characteristics, the lithology of the rocks involved, the depth at which the resources occur and the sources of water supply, may be characterized by very diverse physicochemical parameters. This factor largely determines the technology to be used in their exploitation and the way the geothermal water can be used. This book is focused on the effective use of geothermal water and renewable energy for future needs in order to promote modern, sustainable and effective management of water resources. The research field includes crucial new areas of study: • an improvement in the management of freshwater resources through the use of residual geothermal water; • a review of the technologies available in the field of geothermal water treatment for its (re)use for energetic purposes and freshwater production, and • the development of balneotherapy. The book is aimed at professionals, academics and decision makers worldwide, water sector representatives and administrators, business enterprises specializing in renewable energy management and water treatment, working in the areas of geothermal energy usage, water resources, water supply and energy planning. This book has the potential to become a standard text used by educational institutions and research & development establishments involved in the geothermal water management.

Book Description
Written by leading experts in the field, Cyanobacteria: An Economic Perspective is a comprehensive edited volume covering all areas of an important field and its application to energy, medicine and agriculture. Issues related to environment, food and energy have presented serious challenge to the stability of nation-states. Increasing global population, dwindling agriculture and industrial production, and inequitable distribution of resources and technologies have further aggravated the problem. The burden placed by increasing population on environment and especially on agricultural productivity is phenomenal. To provide food and fuel to such a massive population, it becomes imperative to find new ways and means to increase the production giving due consideration to biosphere’s ability to regenerate resources and provide ecological services. Cyanobacteria are environment friendly resource for commercial production of active biochemicals, drugs and future energy (biodiesel, bioethanol and hydrogen). Topics on isolation, identification and classification of cyanobacteria are discussed, as well as further sections on: summarizing a range of useful products synthesized by cyanobacteria, ecological services provided by cyanobacteria including their harmful effect in water bodies and associated flora and fauna. Chapter on tools, techniques, and patents also focus on the economic importance of the group. This book also provides an insight for future perspectives in each particular field and an extensive bibliography. This book will be a highly useful resource for students, researchers and professionals in academics in the life sciences including microbiology and biotechnology.

Book Description
Phycotoxins are a diverse group of poisonous substances produced by certain seaweed and algae in marine and fresh waters and are important to the scientific community for many reasons, the most obvious being that they pose food safety issues which requires a large investment to regularly monitor the presence of these compounds in foods.Phycotoxins: Chemistry and Biochemistry, second edition presents the most updated information available on phycotoxins. Major emphases are given to chemistry and biochemistry, while origins, mechanism of action, toxicology, and analytical methodology are also covered.Since the publication of the first edition, there have been major advances in the science of marine and aquatic toxins, as well as advances in toxicology, analytical chemistry and pharmacology. This fully revised and updated edition includes several new chapters, including those on ciguatoxins, pinnatoxin, ichthyotoxins, as well as new chapters on food safety control of marine toxins, climate change and water toxins, and microalgae as a source of nutraceuticals. The book will be of interest to toxicologists, marine, food, and plant scientists, as well as researchers and academics in the areas of food science, medicine, public health, toxicology, pharmacology and marine biology.
