Available in PDF, EPUB and Kindle. Book excerpt: Ecotoxicology Modeling is a comprehensive and well-documented text providing a collection of computational methods to the ecotoxicologists primarily interested in the study of the adverse effects of chemicals, their mechanisms of action and/or their environmental fate and behavior. Avoiding mathematical jargon, the book presents numerous case studies to enable the reader to understand the interest but also the limitations of linear and nonlinear models in ecotoxicology. Written by an international team of scientists, Ecotoxicology Modeling is of primary interest to those whose research or professional activity is directly concerned with the development and application of models in ecotoxicology. It is also intended to provide the graduate and post-graduate students with a clear and accessible text covering the main types of modeling approaches used in environmental sciences.

Available in PDF, EPUB and Kindle. Book excerpt: 'Being Alive Well': Health and the Politics of Cree Well-Being is a critical medical anthropological analysis of health theory in the social sciences with specific reference to the James Bay Cree of northern Quebec. In it the author argues that definitions of health are not simply reflections of physiological soundness but convey broader cultural and political realities. The book begins with a treatise on the study of health in the social sciences and a call for a broader understanding of the cultural parameters of any definition of health. Following a chapter that outlines the history of the Whapmagoostui (Great Whale River) region and the people, Adelson presents the underlying symbolic foundations of a Cree concept of health, or miyupimaatisiiun. The core of this book is an ethnographic study of the Whapmagoostui Cree and their particular concept of "health" (miyupimaatisiiun or "being alive well"). That concept is mediated by history, cultural practices, and the contemporary world of the Cree, including their fundamental concerns about their land and culture. In the contemporary context, health – or more specifically, "being alive well" – for the Cree of Great Whale is an intimate fusion of social, political, and personal well-being, thus linking individual bodies to a larger socio-political reality.

Book excerpt: Ecotoxicology offers an overview of current ecotoxicological problems. It includes basic ecotoxicological concepts, as well as information about chemicals and toxic substances that may cause harmful effects on the ecosystem and its living components. The book, with a total of 48 chapters, is divided into three parts. The first part includes the basic concepts of ecotoxicology, starting with an introductory chapter on ecotoxicology as a subdiscipline of ecology; assessment on ecotoxicological effects and risk; and properties and effects of toxic chemicals. These topics are further discussed throughout the book, along with nomenclature, focal topics, and the history of ecotoxicology. The two remaining parts tackle harmful properties and harmful chemicals. The second part also covers bioaccumulation, bioavailability, biodegradability, biodegradation, and biomagnification. It also provides models for ecotoxicological populations, ecosystems and landscapes, and on food-web bioaccumulation. Chemicals including benzene, copper, lead, nitrogen, phenols, pheromones, phthalates, plutonium, and uranium are covered in separate chapters in the final part. This book will be of great value to ecologists, ecotoxicologists, and environmental managers. - Provides an overview of the theory and application of global ecology - International focus and range of ecosystems makes Ecotoxicology an indispensable resource to scientists - Based on the bestselling Encyclopedia of Ecology - Full-color figures and tables support the text and aid in understanding

Book excerpt: The links between trade-related policy reforms and food security is of key concern to many developing countries. This publication sets out the findings of 15 country case studies from Cameroon, Chile, China, Ghana, Guatemala, Guyana, India, Kenya, Malawi, Morocco, Nigeria, Peru, Senegal, Tanzania and Uganda. The coverage includes countries at different stages of development with the main focus on low-income countries that are likely to be at greater risk of food insecurity. The studies examine the impact of trade-related policy reforms on agricultural prices, production and trade, and the consequences for food security issues for each country.

This book was released on 2011-03 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le fleuve Rh ne subit actuellement une forte pollution aux PCB, compos s d'origine anthropique interdits en France depuis 1987. Les tudes mises en place de fa on mieux comprendre et appr hender cette nouvelle pollution passent par l' tude du milieu, des organismes pr sents, des PCB, de leurs transferts via l'eau et les s diments aux premiers maillons de la cha ne alimentaire. Nous avons d crit les modes alimentaires de deux esp ces de poissons tr s pr sents dans le Rh ne: la br me et le barbeau. Cela repr sente une tape dans la r alisation d'un mod le de bioaccumulation des PCB travers les r seaux trophiques impliquant ces esp ces. Ainsi, on pourrait am liorer la compr hension des processus de distribution des PCB dans le Rh ne et pr voir l' volution de la contamination. La mod lisation de la pollution aux PCB implique de r aliser un tat de connaissance de la contamination des poissons dans le temps et l'espace mais aussi par rapport leurs r gimes alimentaires (omnivores et carnassiers). Les profils de contamination sont peu diff rents qu'il y a dix ans mais en concentrations plus importantes avec un site plus impact l'aval d'une usine.

This book was released on 2013-11-25T00:00:00+01:00 with total page 685 pages. Available in PDF, EPUB and Kindle. Book excerpt: La biosurveillance des écosystèmes doit reposer non seulement sur le suivi des populations (structure et dynamique) mais aussi sur la connaissance de leurs niveaux de contamination. Cependant, la prise en compte de la bioaccumulation des contaminants dans les organismes se heurte à la complexité des processus biologiques impliqués, variables selon les espèces, les milieux et les substances chimiques considérés ce qui explique le faible nombre de modèles de transfert disponibles. Par ailleurs, la difficulté technique d'analyser les contaminants persistants et bioaccumulatifs dans les tissus limite également l'intégration de la bioaccumulation dans les programmes de biosurveillance alors même que cette mesure permettrait de caractériser leur devenir, leur biodisponibilité et parfois d'expliquer leurs effets toxiques. Cet ouvrage est une revue des données sur la bioaccumulation des contaminants de l'environnement chez les invertébrés (nématodes, annélides, mollusques, arthropodes) et chez les vertébrés (reptiles, oiseaux, mammifères). L'intérêt de ces données pour l'évaluation du risque écologique, de même que divers modèles d'étude des transferts dans les chaînes trophiques et les relations entre bioaccumulation et effets toxiques sont présentés. Des recommandations pour une meilleure prise en compte de l'analyse de la bioaccumulation en évaluation des risques sont proposées. Ce livre s'adresse aux personnes et organisations publiques ou privées impliquées dans la surveillance des milieux naturels, dans l'évaluation des risques environnementaux des substances chimiques. Il s'adresse également aux chercheurs, enseignants, et étudiants des filières s'intéressant aux problèmes de l'environnement impliquant des contaminations chimiques. Fruit du travail d'enseignants-chercheurs en écotoxicologie de l'université de Franche-Comté (A. de Vaufleury, F. Gimbert), cet ouvrage a été réalisé avec l'appui d'un zoologiste (L. Gomot) en interaction avec des experts-sols de l'ADEME (I. Feix et A.Bispo).
