Available in PDF, EPUB and Kindle. Book excerpt: During the last hlO hundred years man has changed from living in equilibrium with the natural world which sustained him, to a new position in which he is now its undisputed ruler - and very often out of equilibrium - able in a matter of hours to reduce miles of forest to devastated, potential desert. This destructive and wasteful ability has increas~d dramatically over recent years. At the same time however the need for conservation, particularly of plants as a resource for the future, has also become apparent, along with the realisation that advanced technologies can produce more from existing agricultural and forest regions. This may to some extent relieve the heavy pressure on the vulnerable areas where short term over-exploitation leads to permanent destruction of whole ecosystems, and the attendant loss, for ever, of many of the animals and plants which originally lived there. There still remains today a vast number of plant species whose potential is unknown. Maybe they will never have more than aesthetic value to mankind. But who knows where, for example, the next anti cancer agent may be found. And anyway future generations may not be ready to accept such anthropocentric values, and the options should be kept open for the philosophical concept that all life on earth has a right to exist and that man has none to exterminate.

Book excerpt: A spectacular survey of the world's most comprehensive collection of works by the Impressionist master Renoir The Barnes Foundation is home to the world's largest collection of paintings by Pierre-Auguste Renoir (1841-1919). Dr. Albert C. Barnes, a Philadelphia scientist who made his fortune in pharmaceuticals, established the Foundation in 1922 in Merion, Pennsylvania, as an educational institution devoted to the appreciation of the fine arts. A passionate supporter of European modernism, Barnes built a collection that was virtually unrivaled, with massive holdings by Paul Cézanne, Henri Matisse, and Pablo Picasso. But it was Renoir that Barnes admired above all other artists; he thought of him as a god and collected his work tenaciously, amassing 181 works by the painter between 1912 and 1942. All of these Renoirs are included in this lavishly illustrated book. Renoir in the Barnes Foundation tells the fascinating story of Barnes's obsession with the Impressionist master's late works, while offering illuminating new scholarship on the works themselves. Authors Martha Lucy and John House look closely at the key paintings in the collection, placing them in the wider contexts of contemporary artistic, aesthetic, and theoretical debates. The first volume to publish the entirety of Barnes's astonishing Renoir collection, Renoir in the Barnes Foundation is also an engaging study of the artist's critical--and often contested--role in the development of modern art. Published in association with the Barnes Foundation

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.
