This book was released on 1990-07-31 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: In view of the massive change in the area of distribution of many world biota across classical biogeographical realms, and of the drastic restructuring of the biotic components of numerous ecosystems, the Scientific Committee on Problems of the Environment (SCOPE) decided at its general Assembly in Ottawa, Canada, in 1982 to launch a project on the 'Ecology of Biological Invasions'. Several regional meetings were subsequently organized within the framework of SCOPE, in order to single out the peculiarities of the invasions that took place in each region, the behaviour of their invasive species and the invasibility of their ecosystems. Most noteworthy among such workshops were one in Australia in August 1984, one concerning North America and Hawaii in October 1984, and one dealing with southern Africa in November 1985. A leitmotiv of these workshops was that most of the invasive species to those regions were emanating from Europe and the Mediterranean Basin, inadvertently or intentionally introduced by man. It was therefore considered as a timely endeavour to organize the next regional meeting in relation to this region. The workshop on 'Biological Invasions in Europe and the Mediterranean Basin' was held in Montpellier, France, 21 to 23 May 1986, thanks to the financial support of SCOPE and of the A.W. Mellon Foundation, and the logistic facilities of the Centre National de la Recherche Scientifique (C.N .R.S.).

Download or read book Ecological Niches written by Jonathan M. Chase and published by University of Chicago Press. This book was released on 2009-08-11 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why do species live where they live? What determines the abundance and diversity of species in a given area? What role do species play in the functioning of entire ecosystems? All of these questions share a single core concept—the ecological niche. Although the niche concept has fallen into disfavor among ecologists in recent years, Jonathan M. Chase and Mathew A. Leibold argue that the niche is an ideal tool with which to unify disparate research and theoretical approaches in contemporary ecology. Chase and Leibold define the niche as including both what an organism needs from its environment and how that organism's activities shape its environment. Drawing on the theory of consumer-resource interactions, as well as its graphical analysis, they develop a framework for understanding niches that is flexible enough to include a variety of small- and large-scale processes, from resource competition, predation, and stress to community structure, biodiversity, and ecosystem function. Chase and Leibold's synthetic approach will interest ecologists from a wide range of subdisciplines.

Download or read book Plants on Islands written by Martin L. Cody and published by Univ of California Press. This book was released on 2006-06-27 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thorough and meticulous study, the result of nearly a quarter-century of research, examines the island biogeography of plants on continental islands in Barkley Sound, British Columbia. Invaluable both because of its geographical setting and because of the duration of the study, Plants on Islands summarizes the diversity, dynamics, and distribution of the approximately three hundred species of plants on more than two hundred islands. Martin Cody uses his extensive data set to test various aspects of island biogeographic theory. His thoughtful analysis, constrained by taxon and region, elucidates and enhances the understanding of the biogeographic patterns and dynamics. He provides an overview of the basic theory, concepts, and analytical tools of island biogeography. Also discussed are island relaxation to lower equilibrium species numbers post-isolation, plant distributions variously limited by island area, isolation and climatic differences, adaptation to local abiotic and biotic environments within islands, and the evolution of different island phenotypes. The book concludes with a valuable consideration of equilibrium concepts and of the interplay of coexistence and competition. Certain to challenge, Plants on Islands is among the first books to critically analyze the central tenets of the theory of island biogeography.

Download or read book The American Meadow Garden written by John Greenlee and published by Timber Press. This book was released on 2009-09-01 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: If there's one lesson every homeowner must learn, it's this: The traditional lawn is a huge, time consuming, synthetic-chemical sucking mistake. The time has come to look for new ways to create friendly, livable spaces around our homes. In The American Meadow Garden, ornamental grass expert John Greenlee creates a new model for homeowners and gardeners. For Greenlee, a meadow isn't a random assortment of messy, anonymous grasses. Rather, it is a shimmering mini-ecosystem, in which regionally appropriate grasses combine with colorful perennials to form a rich tapestry that is friendly to all life — with minimal input of water, time, and other scarce resources. Kids and pets can play in complete safety, and birds and butterflies flock there. A prairie style planting is a place you want to be. With decades of experience as a nurseryman and designer, John Greenlee is the perfect guide. He details all the practicalities of site preparation, plant selection, and maintenance; particularly valuable are his explanations of how ornamental grasses perform in different climates and areas. Gorgeous photography by Saxon Holt visually illustrates the message with stunning examples of meadow gardens from across the country. We've reached a stage where we can no longer follow past practices unthinkingly, particularly when those practices are wasteful and harmful to the environment. It's time to get rid of the old-fashioned lawn and embrace a sane and healthy future: the American meadow garden.

Available in PDF, EPUB and Kindle. Book excerpt: This best-selling majors ecology book continues to present ecology as a series of problems for readers to critically analyze. No other text presents analytical, quantitative, and statistical ecological information in an equally accessible style. Reflecting the way ecologists actually practice, the book emphasizes the role of experiments in testing ecological ideas and discusses many contemporary and controversial problems related to distribution and abundance. Throughout the book, Krebs thoroughly explains the application of mathematical concepts in ecology while reinforcing these concepts with research references, examples, and interesting end-of-chapter review questions. Thoroughly updated with new examples and references, the book now features a new full-color design and is accompanied by an art CD-ROM for instructors. The field package also includes The Ecology Action Guide, a guide that encourages readers to be environmentally responsible citizens, and a subscription to The Ecology Place (www.ecologyplace.com), a web site and CD-ROM that enables users to become virtual field ecologists by performing experiments such as estimating the number of mice on an imaginary island or restoring prairie land in Iowa. For college instructors and students.

Available in PDF, EPUB and Kindle. Book excerpt: A practical and expertly illustrated field guide to over one hundred grasses, sedges, and rushes "No one will be able to claim that the identification of grasses, sedges, and rushes, which are of fundamental importance both environmentally and economically, are simply 'too difficult' after they have learned to use this excellent guide."--Peter Raven, President Emeritus, Missouri Botanical Garden This elegant and easy-to-use guide is an updated and amended revision of Lauren Brown's seminal Grasses: An Identification Guide, which was first published in 1979. While maintaining the spirit and goals of the original edition--a portable, straightforward, and user-friendly guide for naturalists and plant enthusiasts--the new edition features more than one hundred grasses, sedges, and rushes that are presented with line drawings and color photographs, concise descriptions, and details on the uses of various plants throughout history.
