This book was released on 2007-03-15 with total page 651 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dans le contexte de crise planétaire de l'environnement, l'écotoxicologie apporte des réponses scientifiques précises sur les effets des polluants sur les écosystèmes. Depuis son apparition dans les années 1970, la discipline n'a cessé de se développer, se complexifier, au point qu'il est aujourd'hui difficile d'en avoir une vision d'ensemble. Pionnier français de la discipline, François Ramade propose aujourd'hui cette synthèse exposant et expliquant l'ensemble des notions fondamentales du domaine. L'ouvrage délimite le champ de l'écotoxicologie, notamment en analysant les modalités et mécanismes de la pollution des habitats terrestres et aquatiques. Il fait le tour des notions physiques, biologiques, chimiques et toxicologiques essentielles pour mesurer les effets des polluants. Une large partie de l'ouvrage est consacrée aux conséquences des pollutions. Dans un souci de clarté, les données sont présentées selon un ordre croissant de complexité biologique : de la population à la biosphère en passant par les écosystèmes. Les données les plus récentes ont été intégrées, concernant particulièrement la dimension écologique de la notion de toxique, la détermination des paramètres quantitatifs propres à l'écotoxicologie (indices d'évaluation et seuils de sécurité), la radioécotoxicologie et les biomarqueurs. L'ouvrage prend en compte les réglementations les plus récentes, telle la directive européenne REACH liée à la toxicité de plus de 30 000 produits utilisés dans l'UE, et propose un exposé des méthodes d'évaluation et de prévision du risque environnemental. Ce traité s'adresse aux ingénieurs concernés par la prévention des pollutions et l'évaluation des risques, aux techniciens en charge de la protection environnementale, aux étudiants et enseignants en sciences de l'environnement et en toxicologie, aux agronomes, ainsi qu'au professionnels du domaine biomédical.

This book was released on 2013-11-11 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the papers presented at a Nato Advanced Re search Workshop entitled "DENITRIFICATION IN THE N-CYCLE," held in Braunschweig (W-Germany) from 24 to 27 Mai 1983. All expenses were provided by the North Atlantic Treaty Organization. The scientific programme was in the first instance planned by some members of the Eco-Science Panel under the stimulating organization of Dr. Oscar Ravera and the final programme was prepared in co-operation between Ravera and myself. However, even during the meeting important con tributions were added. The meeting was hosted by the Microbiologi cal Dept. of F.A.L., which also took care of the organizatory as pects. Nitrate is constantly lost from both terrestial and aquatic ecosystems, causing rnixed feelings between ecologists and agricul turists. While bacteriologically very rnuch is known, the ecology of the processes is still poorly understood, nor can it be evaluated what it rneans as an econornic loss for farrners and world food produc tion. Therefore this NATO Advanced Workshop was established to per mit a lirnited nurnber of scientists active in this field to corne to gether for a short while to address the following objectives: 1) To exchange ideas between scientists (bacteriologists and ecologists) and agronornists. 2) To assess the state of the art. 3) To discuss the difficulties of experimentation in the field. 4) To define future research. In order to accornplish these objectives, the workshopwas organ ized in three parts with the following thernes: 1) Bacteriological aspects of dentrification

This book was released on 2012-12-06 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical Africa escaped from the glaciers that covered the temperate parts of the world during the Ice Age. The legacy is that most of the parent materials of the soils of tropical Africa are old, highly weathered and devoid of bases and phosphate-bearing minerals. Traditional farming systems which were relatively stable and sustainable relied on long fallow periods after one to two years of cropping to maintain the productive capacity of the soils. In recent times and especially in densely populated areas, a sizeable class of 'landless' farmers have begun to cultivate marginal lands or to invade the 'forest reserves' thereby exacerbating the problems of land and environ mental degradation. of soil fertility that will facilitate the production of adequate quantities of the principle Maintaining a level staples has become a major challenge to agricultural scientists in tropical Africa. To increase the nutrient supplying power of soils requires the inputs of fertilizers. These can be organic or inorganic. The efficiency with which these externally supplied inputs can increase agricultural production and reduce soil and environmental deterioration is dependent on the ability of scientists to determine the right types and quantities of the products to apply to each soil, crop and cropping system as well as the ability of farmers to acquire requisite farm manage ment skills.

Available in PDF, EPUB and Kindle. Book excerpt: A number of excellent textbooks on general ecology are currently available but‚ to date‚ none have been dedicated to the study of soil ecology. This is important because the soil‚ as the ‘epidermis’ of our planet‚ is the major component of the terrestrial biosphere. In the present age‚ it is difficult to understand how one could be interested in general ecology without having some knowledge of the soil and further‚ to study the soil without taking into account its biological components and ecological setting. It is this deficiency that the two authors‚ Patrick Lavelle and Alister Spain‚ have wished to address in writing their text. A reading of this work‚ entitled ‘Soil Ecology’‚ shows it to be very complete and extremely innovative in its conceptual plan. In addition‚ it follows straightforwardly through a development which unfolds over four substantial chapters. Firstly‚ the authors consider the soil as a porous and finely divided medium of b- organomineral origin‚ whose physical structure and organisation foster the development of a multitude of specifically adapted organisms (microbial communities‚ roots of higher plants‚ macro-invertebrates).
