Book excerpt: Le but du doctorat a été de démontrer le potentiel du macrophyte aquatique submergé du lac Léman, "Elodea nuttallii", pour indiquer les risques de pollution par les métaux. Des expériences de contamination ont été réalisées, au laboratoire, pendant cinq jours, en système statique et en système continu. Par ces deux modes de contamination, les métaux ont été accumulés selon l'affinité croissante suivante : Mo

Book Synopsis Conséquences de l'introduction de deux espèces végétales aquatiques exotiques (Elodea nuttallii et Elodea canadensis) sur les interactions plantes-macroinvertébrés by : Anatole Boiché
Download or read book Conséquences de l'introduction de deux espèces végétales aquatiques exotiques (Elodea nuttallii et Elodea canadensis) sur les interactions plantes-macroinvertébrés written by Anatole Boiché and published by . This book was released on 2010 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nous avons utilisé comme modèle biologique Elodea nuttallii et Elodea canadensis, plantes originaires d'Amérique du Nord et présente en France depuis le dix-neuvième siècle (E. canadensis) et les années 1950 (E. nuttallii). E. nuttallii est actuellement en phase d'expansion tandis que E. canadensis est considérée comme naturalisée en Europe. Notre objectif principal consiste à étudier les conséquences de l’invasion de E. nuttallii sur les communautés de macroinvertébrés. Nous avons d'abord étudié le rôle d'habitat de E. nuttallii et des plantes indigènes Ranunculus peltatus et Callitriche platycarpa pour les macroinvertébrés dans des ruisseaux qui diffèrent par leurs niveaux de trophie. Le principal résultat obtenu montre que le niveau de trophie des cours d'eau est le principal facteur influençant la répartition des invertébrés, l'espèce de macrophyte étant secondaire. E. nuttallii accueille des communautés d'invertébrés à la composition et à la structure intermédiaire par rapport à R. peltatus et C. platycarpa. Les propriétés architecturales des trois macrophytes auraient un rôle dans la répartition des invertébrés entre les différents herbiers. Parmi les invertébrés peuplant les macrophytes, les gammares ont un régime généraliste. Nous avons d'abord validé l'utilisation de Gammarus roeseli comme modèle pour tester l'appétence des macrophytes. Nous avons ensuite évalué l'évolution saisonnière de l'appétence des élodées et mis en évidence les mécanismes évolutifs qui permettent à une espèce invasive de proliférer et de s'intégrer dans les écosystèmes. E. canadensis alloue son énergie à la défense tandis que E. nuttallii a une stratégie de croissance végétative.
Book Synopsis Handbook of Ecotoxicology by : Peter P. Calow
Download or read book Handbook of Ecotoxicology written by Peter P. Calow and published by John Wiley & Sons. This book was released on 2009-06-05 with total page 901 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Handbook of Ecotoxicology provides a readily accessible, yet critical collection of information on ecotoxicological testing. Now available in a single paperback volume, this handbook represents excellent value. Part A concentrates on techniques, especially those tests used for prediction. Thorough descriptions of the main tests are provided, followed by critical analyses in terms of ease of handling, repeatability and ecological relevance, and finally, an extensive bibliography citing key documents describing test methods and key papers evaluating them. Part B focuses on the toxicants themselves: summarising their ecological effects, describing ways of predicting effects from physico-chemical properties alone, and describing and discussing fate models. Now available as a single volume in paperback An invaluable reference resource
Book Synopsis Ecological Microcosms by : Robert J. Beyers
Download or read book Ecological Microcosms written by Robert J. Beyers and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 566 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecological Microcosms is a seminal work which reviews the expanding field of enclosed ecosystem research, and relates the results and models of microcosm studies to general concepts in ecology. Microcosms are miniaturized pieces of our biosphere, ranging from streams and lakes to terraria, agroecosystems, and waste systems. The study of these simplified ecosystems is providing provocative insights into ecological principles as well as issues of environmental management and global stability. The authors have used the well-known thermodynamic approach of H.T. Odum and numerous computer simulations. The book also includes an evaluation of alternative mesocosm approaches for the support of humans in space, as well as appendices to aid in the teaching of environmental concepts using student-created microcosms. Ecological Microcosms will be of interest to ecologists, environmental engineers, policy makers and environmental managers, space scientists, and educators. Robert J. Beyers is a Professor of Biology at the University of South Alabama. Howard T. Odum is Graduate Research Professor of Environmental Engineering Sciences at the University of Florida, and was awarded, with Eugene Odum, the 1987 Crafoord Prize in the Biosciences.

Book Synopsis Linking Restoration and Ecological Succession by : Lawrence R. Walker
Download or read book Linking Restoration and Ecological Succession written by Lawrence R. Walker and published by Springer Science & Business Media. This book was released on 2007-10-16 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: This innovative book integrates practical information from restoration projects around the world with the latest developments in successional theory. It recognizes the critical roles of disturbance ecology, landscape ecology, ecological assembly, invasion biology, ecosystem health, and historical ecology in habitat restoration. It argues that restoration within a successional context will best utilize the lessons from each of these disciplines.

Book Synopsis Toxicity Assessment by : Carlos M. Palmeira
Download or read book Toxicity Assessment written by Carlos M. Palmeira and published by . This book was released on 2021 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book collects protocols from different areas of knowledge to assist in the identification of toxic effects exerted by different xenobiotics. At the same time as classical techniques are presented, modern techniques with alternative models to the use of animals are also presented. Given the ever-increasing exposure to different compounds and their effects on population health, the assessment of multiple endpoints is of utmost importance for better risk assessment, and this collection addresses that need. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Toxicity Assessment: Methods and Protocols aims to serve researchers in this vast field of science as they seek to better understand the mechanisms of action of different xenobiotics.
Book Synopsis Environmental Ethics and Law by : Robert Jay Goldstein
Download or read book Environmental Ethics and Law written by Robert Jay Goldstein and published by Ashgate Publishing. This book was released on 2004 with total page 734 pages. Available in PDF, EPUB and Kindle. Book excerpt: This collection explores a broad range of topics approaching environmental ethics from many different angles. A common thread running through the volume is the analysis of ethical principles as the backbone of practical policies and law for the benefit of the environment, and ultimately for the benefit of its inhabitants. The contributors are all at the forefront of their respective fields and fall into two essential categories: well-established scholars in the field of environmental ethics; and a group of newer voices that have followed what might be characterized as the first wave of environmental ethics scholarship.
