Download or read book Soil Biology Guide written by Daniel L. Dindal and published by John Wiley & Sons. This book was released on 1991-01-16 with total page 1381 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive study of the biology, taxonomy, and ecology of each of the soil biotic groups. The first chapter presents an ecological approach to soil studies. The remaining 42 chapters provide specific information on each of the taxonomic groupings. Contains illustrated identification keys to each group. Some keys go by functional morphological delineations; others lead the reader to classical identification at family, genus, or species levels. Some incorporate descriptions of new genera and species. Especially useful for the study of mesic, xeric, and hydric terrestrial sites. Includes an extensive bibliography.
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.

Available in PDF, EPUB and Kindle. Book excerpt: Ce manuel pratique aide à comprendre les grands principes régissant la morphologie des cours d’eau et leur dynamique pour mieux concevoir des aménagements qui sauront résister aux crues sans déséquilibrer pour autant les écosystèmes. Le chapitre 1 donne les définitions, principes de base et résultats d’hydraulique à surface libre. Les chapitres 2 à 4 approfondissent le diagnostic des rivières en tenant compte du transport solide et de la constante interaction entre l’écoulement, le fond, les berges et le champ d’inondation. Les chapitres 5 à 9 exposent les différents aménagements et entretiens pour utiliser l’eau ou se protéger des crues. Cette 2e édition, entièrement réactualisée et augmentée de nombreux schémas et photos, aborde de nouveaux points : les calculs hydrauliques des déversoirs latéraux, des estimations de débit solide adaptées aux fortes pentes, la morphologie des torrents et les conséquences morphologiques des barrages, la restauration morphologique des rivières, les processus d’érosion par surverse, la conception des zones d’expansion de crues, des procédés de protection de berge ou de traitement des digues, la nouvelle norme sur les enrochements, etc... Diagnostic, aménagement et gestion des rivières s’adresse aux professionnels en charge de la gestion et de l’aménagement des cours d’eau ou de la police de l’eau : cabinets d’ingénierie, collectivités territoriales, établissements publics, sociétés d’aménagement régional et services déconcentrés et centraux de l’État. Il sera une aide précieuse pour les étudiants en écoles d’ingénieur ou en université et intéressera les chercheurs en mécanique des fluides, géomorphologie ou écologie fluviale.

Download or read book The Living Elephants written by Raman Sukumar and published by Oxford University Press. This book was released on 2003-09-11 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Living Elephants is the authoritative resource for information on both Asian and African elephants. From the ancient origins of the proboscideans to the present-day crisis of the living elephants, this volume synthesizes the behavior, ecology and conservation of elephants, while covering also the history of human interactions with elephants, all within the theoretical framework of evolutionary biology. The book begins with a survey of the 60-million year evolutionary history of the proboscideans emphasizing the role of climate and vegetation change in giving rise to a bewildering array of species, but also discussing the possible role of humans in the late Pleistocene extinction of mastodonts and mammoths. The latest information on the molecular genetics of African and Asian elephants and its taxonomic implications are then presented. The rise of the elephant culture in Asia, and its early demise in Africa are traced along with an original interpretation of this unique animal-human relationship. The book then moves on to the social life of elephants as it relates to reproductive strategies of males and females, development of behavior in young, communication, ranging patterns, and societal organization. The foraging strategies of elephants, their impact on the vegetation and landscape are then discussed. The dynamics of elephant populations in relation to hunting for ivory and their population viability are described with the aid of mathematical models. A detailed account of elephant-human interactions includes a treatment of crop depredation by elephants in relation to their natural ecology, manslaughter by elephants, habitat manipulation by humans, and a history of the ivory trade and poaching in the two continents. The ecological information is brought together in the final chapter to formulate a set of pragmatic recommendations for the long-term conservation of elephants. The broadest treatment of the subject yet undertaken, by one of the leading workers in the field, Raman Sukumar, the book promises to bring the understanding of elephants to a new level. It should be of interest not only to biologists but also a broader audience including field ecologists, wildlife administrators, historians, conservationists and all those interested in elephants and their future.
