Available in PDF, EPUB and Kindle. Book excerpt: When deformed frogs-many with missing legs or eyes, footless stumps, or misshapen jaws-began to emerge from Minnesota wetlands, alarm bells went off. What caused such deformities? Pollution? Ultraviolet rays? Biological agents? And could the mysterious cause also pose a threat to humans? Former government biologist Judy Helgen provides an inside view of a highly charged environmental issue that continues to spark controversy among scientists, politicians, and government agencies.

Book excerpt: This book focuses on global aspects of common carps' biological features, ecology and diseases. Common carp have a high adaptive capacity in a wide range of conditions and habitats that have enabled them to be distributed across most regions of the world, except Antarctica. Common carp play an essential role in feeding the world as one of the highest sources of animal protein for humans worldwide. Therefore, an understanding of various biological aspects of common carp across the environments they inhabit are essential for their care and management in wild or cultured situations. Creating a compendium of knowledge surrounding common carp biology will provide useful knowledge for aquaculturists and scientists working to maximize their production. Biological aspects of common carp vary depending on the mode of management and environment in which they are growing. This book describes in detail various important biological aspects, particularly habitat, growth and production, food habits, breeding, maturation, fecundity, and behavior of common carp, which will benefit aquaculturists, students, and scientists.Zooplankton and zoobenthos communities are critical components of freshwater ecosystems and are very important for sustaining carp populations, both wild and cultured. This book also helps the reader to understand the ecology of carp ponds, particularly how common carp and pond management influence zooplankton and zoobenthos ecology. Common carp is the preferred food fish for many Asian and European consumers. Two chapters describe nutritional aspects of common carp, with special attention concerning factors that influence meat quality in terms of proximate and fatty acids composition.Like other fish, common carp also encounter many diseases during their lifespan. Various biological agents (pathogens) - particularly viruses, bacteria, fungi and parasites - may initiate disease. Their growth and abundance are related to various environmental factors such as temperature, various dissolved gases, pH, and availability of food. Therefore, in addition to biology and ecology, this book provides a clear understanding about various methodologies of identifying various diseases of common carp, together with methods and the methods of managing disease, particularly preventative and control measures.

This book was released on 2017-07-28 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: Between 1973 and 2016, the ways to manipulate DNA to endow new characteristics in an organism (that is, biotechnology) have advanced, enabling the development of products that were not previously possible. What will the likely future products of biotechnology be over the next 5â€"10 years? What scientific capabilities, tools, and/or expertise may be needed by the regulatory agencies to ensure they make efficient and sound evaluations of the likely future products of biotechnology? Preparing for Future Products of Biotechnology analyzes the future landscape of biotechnology products and seeks to inform forthcoming policy making. This report identifies potential new risks and frameworks for risk assessment and areas in which the risks or lack of risks relating to the products of biotechnology are well understood.

Download or read book Fish Physiology Organic Chemical Toxicology of Fishes written by Keith B. Tierney and published by Academic Press. This book was released on 2013-12-04 with total page 570 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fish Physiology: Organic Chemical Toxicology of Fishes discusses the different types of organic chemical contaminants and their respective toxic effects in fish. The book also covers the detection of dissolved organic compounds and methods to assess organic toxicity. Substances addressed in this book include organometallics, hydrocarbons, endocrine disrupting compounds (EDCs), insecticides, herbicides, and pharmaceuticals. Fish are exposed to an ever-increasing array of organic chemicals that find their way into rivers and oceans. Some of these compounds are no longer being produced but nonetheless persist within the environment (persistent organic pollutants, or POPs). The exposure of fish to toxic organic compounds has potential impact on human, fish, and ecosystem health. Yet the regulations that govern environmental water quality vary worldwide, and compliance is never complete. This book provides a crucial resource on these issues for researchers in zoology, fish physiology, and related fields; applied researchers in environmental monitoring, conservation biology, and toxicology; and university-level students and instructors in these areas. Organized by type of toxic organic chemicals Includes metals, POPs, EDCs, herbicides, insecticides, and pharmaceuticals Measures toxicity in a variety of ways aside from lethality Probes the toxic effects of compound mixtures as well as single pollutants

Download or read book An Introduction to Aquatic Toxicology written by Mikko Nikinmaa and published by Elsevier. This book was released on 2014-07-01 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: An Introduction to Aquatic Toxicology is an introductory reference for all aspects of toxicology pertaining to aquatic environments. As water sources diminish, the need to understand the effects that contaminants may have on aquatic organisms and ecosystems increases in importance. This book will provide you with a solid understanding of aquatic toxicology, its past, its cutting-edge present and its likely future. An Introduction to Aquatic Toxicology will introduce you to the global issue of aquatic contamination, detailing the major sources of contamination, from where they originate, and their effects on aquatic organisms and their environment. State-of-the-art toxicological topics covered include nanotoxicology, toxicogenomics, bioinformatics, transcriptomics, metabolomics, as well as water management and the toxicological effects of major environmental issues such as algal blooms, climate change and ocean acidification. This book is intended for anyone who wants to know more about the impact of toxicants on aquatic organisms and ecosystems, or to keep up to date with recent and future developments in the field. Provides with the latest perspectives on the impacts of toxicants on aquatic environments, such as nanotoxicology, toxicogenomics, ocean acidification and eutrophication Offers a complete overview, beginning with the origins of aquatic toxicology and concluding with potential future challenges Includes guidance on testing methods and a glossary of aquatic toxicology terms
