Book excerpt: L'écologie à l'école, c'est d'abord l'étude des relations à l'intérieur du groupe social de la classe, de celles avec le milieu naturel, les familles, le système administratif et le milieu social en général. C'est ensuite la connaissance de moyens à travers une méthodologie d'initiation à l'environnement, des réglementations et un système de classes de nature transplantées. C'est enfin l'utilisation appropriée de techniques au service de l'appréciation, de la compréhension et de la maîtrise responsable de notre environnement : techniques de l'information et de la documentation, de l'expression orale et écrite, de l'audiovisuel et de l'observation

Download or read book Wildland Recreation written by William E. Hammitt and published by John Wiley & Sons. This book was released on 2015-04-20 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: WILDLAND RECREATION THE AUTHORITATIVE GUIDE TO UNDERSTANDING AND MANAGING THE ECOLOGICAL IMPACTS OF RECREATIONAL ACTIVITIES IN WILDLANDS This third edition provides an updated and thorough examination of the ecological impacts of recreational use on wildlands and the best management practices to employ in places where recreation and preservation of natural conditions are important – and often conflicting – objectives. Covering the latest research, this edition provides detailed information about the environmental changes that result from recreational use. It describes spatial patterns of impact and trends over time, and then explores the factors that determine the magnitude of impact, including the amount of use, the type and behavior of use, and the environmental durability. Numerous examples, drawn from parks and recreation areas around the world, give readers an insight into why certain areas are more heavily damaged than others, and demonstrate the techniques available to mitigate damage. The book incorporates both the first-hand experience of the authors and an exhaustive review of the world’s literature on the subject. Boxes provide quick access to important material, and further resources are referenced in an extensive bibliography. Essential reading for all park and protected area management professionals, this book is also a useful textbook for upper division undergraduate and graduate students on recreation ecology and recreation management courses.

Download or read book Root Ecology written by Hans de Kroon and published by Springer Science & Business Media. This book was released on 2003-05-21 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the course of evolution, a great variety of root systems have learned to overcome the many physical, biochemical and biological problems brought about by soil. This development has made them a fascinating object of scientific study. This volume gives an overview of how roots have adapted to the soil environment and which roles they play in the soil ecosystem. The text describes the form and function of roots, their temporal and spatial distribution, and their turnover rate in various ecosystems. Subsequently, a physiological background is provided for basic functions, such as carbon acquisition, water and solute movement, and for their responses to three major abiotic stresses, i.e. hard soil structure, drought and flooding. The volume concludes with the interactions of roots with other organisms of the complex soil ecosystem, including symbiosis, competition, and the function of roots as a food source.
