Supplying sustenance for millions of the poorest people in the world, freshwater flora and fauna also contribute to overall economic well-being by means of export commodity trade, tourism, and recreation. As sources of high-quality nutrients, freshwater flora and fauna of edible value represent a viable option for alleviating the problems related t
Many species of animals and plants live in water; some, like fish, spend all their lives underwater, whereas others, like toads and salamanders, may use surface waters only during the spring breeding season or as juveniles. Some aquatic creatures live their entire lives in the deep ocean, whereas others, like water striders, spend their life skipping along the surface of water. Biodiversity is not only the richness of species; it is also their genetic variety and the multiple habitats and ecosystems in which these plants and animals live. Ecosystems contain both the living plants and animals and the nonliving elements (water, sunlight, soils) on which they depend.Nutritional Freshwater Life covers the state of the art information on the characteristics of nutritionally important freshwater animals and plants. The book includes detailed information on algae and plants, crustaceans, mollusks, fish, and frogs, including with its characteristics such as habitats, global distribution, nutritional facts, and biological features.Habitats in the sea, in freshwater, and on land differ dramatically in species composition and diversity. Of the roughly 1.5 million known species of macroscopic organisms on earth, the modern ocean - despite its much larger area and volume - supports only about 15% of species, whereas terrestrial environments account for about 80% of species, and freshwater for the remaining 5%. Even when taking into account previously undetected biodiversity in all of the physical realms revealed through molecular techniques, these differences appear to be robust - certainly among multicellular organisms.
Freshwater is a finite resource and is being deteriorated directly and indirectly by anthropogenic pressures. Preserving the quality and availability of freshwater resources is becoming one of the most pressing environmental challenges on the international horizon. To ensure the preservation as well as availability of freshwater resources, there is a need to understand the ecology of the freshwater systems, pollution problems, their impacts, restoration techniques to be opted and the conservation measures. In this backdrop the present book on ‘Freshwater Pollution Dynamics and Remediation’ has been compiled. The book provides an understanding about the present state of art, pollution impacts including the changes in the environmental quality as well as the shift in the aquatic biological communities of the fragile freshwater ecosystems. Besides, the impact of deteriorating quality of the freshwater ecosystems on the animal and human health is also discussed in detail. This book provides a comprehensive account of the techniques based on updated research in biotechnology, bio-remediation, phyto-remediation and nano-bioremediation. The role of biosorpers and biofilms as a remediation tool has also been detailed. The book is a ready reference for researchers, scientists and educators who are involved in the freshwater pollution, remediation and management studies. The book editors with an expertise in diverse research fields in freshwater ecosystems have congregated the most inclusive research accounts on the freshwater pollution and remediation and thus developed a repository of diverse knowledge on the subject
Research has clearly established a link between omega fatty acids and general health, particularly cardiovascular health. Omega Fatty Acids in Brain and Neurological Health, Second Edition, illustrates the importance of omega-3 fatty acids in longevity, cognitive impairment and structure and function of the brain's neurons and also the adverse effects of omega-6 fatty acids on neurological function. This book encompasses some of the most recent research on the links between omega fatty acids and the developing brain, aging, dementia, Alzheimer's disease and multiple sclerosis, including the role of omega-3 fatty acid supplements on hippocampal neurogenesis, substantia nigra modulation, migraine headaches, the developing brain in animals, sleep and neurodegenerative diseases. This completely updated second edition focuses on the counterbalancing dietary and tissue omega-6 fatty acids as well as it studies the effects in pregnancy and early infancy, animal model studies and autoimmune neurological diseases. Provides a comprehensive introduction to omega-3 and omega-6 fatty acids in neurological health and directions for future research Features novel focus on the adverse effects of omega-6 fatty acids on neurological function and the counterbalancing of dietary and tissue omega-6 Illustrates the importance of omega-3 fatty acids in longevity and cognitive impairment Features new chapters on early effects in pregnancy and early infancy, animal model studies and autoimmune neurological diseases Discusses links between omega fatty acids and the developing brain, aging, dementia, Alzheimer's disease and multiple sclerosis, including the role of omega-3 fatty acid supplements
