Download or read book American Perceptions of Immigrant and Invasive Species written by Peter Coates and published by Univ of California Press. This book was released on 2007-01-09 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sometimes by accident and sometimes on purpose, humans have transported plants and animals to new habitats around the world. Arriving in ever-increasing numbers to American soil, recent invaders have competed with, preyed on, hybridized with, and carried diseases to native species, transforming our ecosystems and creating anxiety among environmentalists and the general public. But is American anxiety over this crisis of ecological identity a recent phenomenon? Charting shifting attitudes to alien species since the 1850s, Peter Coates brings to light the rich cultural and historical aspects of this story by situating the history of immigrant flora and fauna within the wider context of human immigration. Through an illuminating series of particular invasions, including the English sparrow and the eucalyptus tree, what he finds is that we have always perceived plants and animals in relation to ourselves and the polities to which we belong. Setting the saga of human relations with the environment in the broad context of scientific, social, and cultural history, this thought-provoking book demonstrates how profoundly notions of nationality and debates over race and immigration have shaped American understandings of the natural world.

This book was released on 2012-12-06 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Social and natural scientists often are called upon to produce, or participate, in the pro duction of forecasts. This volume assembles essays that (a) describe the organizational and political context of applied forecasting, (b) review the state-of-the-art for many fore casting models and methods, and (c) discuss issues of predictability, the implications of forecaSt errors, and model construction, linkage and verification. The essays should be of particular interest to social and natural scientists concerned with forecasting large-scale systems. This project had its origins in discussions of social forecasts and forecasting method ologies initiated a few years ago by several social and natural science members of the Social Science Research Council's Committee on Social Indicators. It became appar ent in these discussions that certain similar problems were confronted in forecasting large-scale systems-be they social or natural. In response, the Committee hypothesized that much could be learned through more extended and systematic interchanges among social and natural scientists focusing on the formal methodologies applied in forecasting. To put this conjecture to the test, the Committee sponsored a conference at the National Center for Atmospheric Research in Boulder, Colorado, on June 10-13, 1984, on forecasting in the social and natural sciences. The conference was co-chaired by Committee members Kenneth C. Land and Stephen H. Schneider representing, respectively, the social and natural science mem bership of the Committee. Support for the conference was provided by a grant to the Council from the Division of Social and Economic Science of the National Science Foundation.

Download or read book The Ecology of Invasions by Animals and Plants written by Charles S. Elton and published by Springer Nature. This book was released on 2020-03-10 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elton sought to articulate more explicitly his vision of an entire field of invasion science. The 1958 book, aimed at an educated lay audience, was almost wholly descriptive, dominated by striking examples of the nature and scope of particular invasions beginning with the seven examples detailed in Chapter 1. From the materials in the proof copy and other sources, we can imagine a new edition would also have targeted biologists and been somewhat more technical and prescriptive. In autobiographical notes he penned near the end of his life, Elton wrote regarding EIAP, “This whole subject has deep significance for the study of plant and animal communities and their balance (or unbalance),”19 and indeed many of the reprints and notes refer to interactions among species and community-wide effects.

This book was released on 2012-12-06 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: n this book I have tried to bring together ideas from three different Istreams of thought with which I have been closely concerned during the last thirty years or so. The first is faunal history, usually regarded as a purely academic subject, but to some of whose events can be traced a number of the serious dislocations taking place in the world today. The second is ecology, particularly the structure and dynamics of populations. The third is conservation. I first published a few ideas about the signifi cance of invasions in 1943, in a war-time review called Polish Science and Learning, under the title of 'The changing realms of animal life'. Since then I have had the opportunity to think pretty hard about conservation, while taking part in the planning and development of the Nature Con servancy. In March 1957 I gave three broadcasts in the B. B. C. 's Third Programme, under the title of 'Balance and Barrier'. These were sub sequently printed in The Listener (1957, Vol. 57, pp. 514-15,556-7,596-7, and 600). The present book is essentially an expansion of these. I am extremely grateful to Mr James C. Thornton and Dr John Simons for in planning and giving these talks. advice and help In preparing this book I have had invaluable assistance from the staff of the Bureau of Animal Population. Miss C. M. Gibbs typed the fair copy. Miss M.
