Download or read book Environmental Risk Analysis for Asian Oriented Risk Based Watershed Management written by Minoru Yoneda and published by Springer. This book was released on 2018-05-07 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication is a practical guidebook on environmental risk assessment, especially for watershed-scale management. It highlights case studies of watershed environmental risk in Malaysia, including the potential health risks as well as screening methods and management in practice. In order to apply environmental risk assessment methods for the management of toxic chemicals, it is necessary to consider the geological and climate features of each country as well as their cultural characteristics. Focusing on Malaysia as a representative country, the book also discusses studies in other Asian countries. The insights provided can be applied to advanced and developing countries alike. A suitable textbook for graduate students, it is also a valuable reference source for researchers, practitioners and policymakers.

Download or read book Phenotypic Plasticity of Insects written by Douglas Whitman and published by CRC Press. This book was released on 2009 with total page 914 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the profound importance of phenotypic plasticity as a central organizing theme for understanding biology. Chapters take a broad, integrative approach to explain how physical and biological environmental stimuli (temperature, photoperiod, nutrition, population density, predator presence, etc.), influence insect biochemical, physiological, learning, and developmental processes, altering phenotype, which then influences performance, ecology, life-history, survival, fitness, and subsequent evolution. Topics include endocrinology, development, body size, allometry, polyphenism, reproduction, reproductive and life-history tradeoffs, alternative mating and life-history strategies, density-dependent prophylaxis, physiological adaptation, acclimation, homeostasis, heat-shock proteins, learning, adaptive anti-predator behavior, and evolution of phenotypic plasticity.

Download or read book Environmental Hygiene written by Norbert H. Seemayer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental pollution raises serious concern worldwide about effects on human health. Based on a recent meeting, this book focuses on diverse aspects of environmental hygiene, dealing with the evaluation of chemical and physical agents and their relevance to human health. To assess the toxicity, mutagenicity and carcinogenicity of environmental pollutants, a variety of methodological approaches, both in vivo and in vitro, as tissue cultures, isolated organs and animal models, were developed and are described in detail. Data on human exposure, biological monitoring and epidemiological studies are also included. Problems of environmental control and legislation as well as possible provisional steps are discussed.
