Book excerpt: This book explores the most important aspects of the biology, ecology and management of what is one of the world's worst weeds. Originally regarded as a major weed in Australia and India, Parthenium weed is now widespread in around 48 countries in Africa, Asia and the South Pacific, and has the potential to spread to new countries in Africa, Asia and Europe. This book, which is a collective effort by 27 members of the International Parthenium Weed Network, addresses research and knowledge gaps for different countries. It examines the weed's mode of spread, its impact on agricultural production, its effect on the environment and on human health, and its management using biological control, as well as cultural, physical and chemical approaches. It also considers the coordination of the weed's management, possible uses for Parthenium weed, its present distribution and how this is impacted by climate change. This book includes: A detailed analysis of Parthenium weed biology. Experiences with Parthenium weed worldwide. An explanation of practical management options. This book will be of interest to graduate students and researchers in universities and institutes, in the fields of plant ecology, botany, agriculture, conservation and restoration ecology.

Download or read book Fifty Years of Invasion Ecology written by David M. Richardson and published by John Wiley & Sons. This book was released on 2011-01-18 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasion ecology is the study of the causes and consequences of the introduction of organisms to areas outside their native range. Interest in this field has exploded in the past few decades. Explaining why and how organisms are moved around the world, how and why some become established and invade, and how best to manage invasive species in the face of global change are all crucial issues that interest biogeographers, ecologists and environmental managers in all parts of the world. This book brings together the insights of more than 50 authors to examine the origins, foundations, current dimensions and potential trajectories of invasion ecology. It revisits key tenets of the foundations of invasion ecology, including contributions of pioneering naturalists of the 19th century, including Charles Darwin and British ecologist Charles Elton, whose 1958 monograph on invasive species is widely acknowledged as having focussed scientific attention on biological invasions.
Download or read book Forest Soils written by Khan Towhid Osman and published by Springer Science & Business Media. This book was released on 2013-12-12 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest soil characteristics are not only unique but their interpretation also differs from cropland soils. Just as there are diverse forest types, there are many soil variants that need different management. Today, forest plantations are being intensively managed for profitable timber, pulpwood and energy production. Site selection, species selection, site productivity evaluation, silvicultural treatments, and soil amendments need crucial soil information. This book provides a comprehensive overview of the physical, chemical and biological properties of forest soils and their implications on forest vegetation. Topics discussed include: major forest types of the world and their associated soils; forest biomass and nutrient dynamics; organic matter turnover and nutrient recycling; forest soil disturbance; forest soil and climate change; and forest soil management and silvicultural treatments.

Download or read book Novel Ecosystems written by Richard J. Hobbs and published by John Wiley & Sons. This book was released on 2013-01-07 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: Land conversion, climate change and species invasions are contributing to the widespread emergence of novel ecosystems, which demand a shift in how we think about traditional approaches to conservation, restoration and environmental management. They are novel because they exist without historical precedents and are self-sustaining. Traditional approaches emphasizing native species and historical continuity are challenged by novel ecosystems that deliver critical ecosystems services or are simply immune to practical restorative efforts. Some fear that, by raising the issue of novel ecosystems, we are simply paving the way for a more laissez-faire attitude to conservation and restoration. Regardless of the range of views and perceptions about novel ecosystems, their existence is becoming ever more obvious and prevalent in today’s rapidly changing world. In this first comprehensive volume to look at the ecological, social, cultural, ethical and policy dimensions of novel ecosystems, the authors argue these altered systems are overdue for careful analysis and that we need to figure out how to intervene in them responsibly. This book brings together researchers from a range of disciplines together with practitioners and policy makers to explore the questions surrounding novel ecosystems. It includes chapters on key concepts and methodologies for deciding when and how to intervene in systems, as well as a rich collection of case studies and perspective pieces. It will be a valuable resource for researchers, managers and policy makers interested in the question of how humanity manages and restores ecosystems in a rapidly changing world.

Download or read book Non Chemical Weed Control written by Khawar Jabran and published by Academic Press. This book was released on 2018-01-03 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Non-Chemical Weed Control is the first book to present an overview of plant crop protection against non-food plants using non-chemical means. Plants growing wild—particularly unwanted plants found in cultivated ground to the exclusion of the desired crop—have been treated with herbicides and chemical treatments in the past. As concern over environmental, food and consumer safety increases, research has turned to alternatives, including the use of cover crops, thermal treatments and biotechnology to reduce and eliminate unwanted plants. This book provides insight into existing and emerging alternative crop protection methods and includes lessons learned from past methodologies. As crop production resources decline while consumer concerns over safety increase, the effective control of weeds is imperative to insure the maximum possible levels of soil, sunlight and nutrients reach the crop plants. - Allows reader to identify the most appropriate solution based on their individual use or case - Provides researchers, students and growers with current concepts regarding the use of modern, environment-friendly weed control techniques - Presents methods of weed management—an important part of integrated weed management in the future - Exploits the knowledge gained from past sustainable weed management efforts
Download or read book Invasive Exotic Species in the Sonoran Region written by Barbara Tellman and published by University of Arizona Press. This book was released on 2002-05 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: All over the planet, organisms of many species are appearing outside of their natural habitatsÑoften carried by that particularly peripatetic species Homo sapiens. This book marks the first comprehensive attempt to address problems posed by expanding populations of exotic plant and animal species in the Sonoran Desert and adjacent grasslands and riparian areas. It describes the arrival and spread of non-native species as diverse as rats and saltcedar, covering both their impacts and the management of those impacts. It is estimated that as much as 60 percent of the vegetative cover of the Sonoita Creek-Patagonia Reserve, the first Nature Conservancy area designated in Arizona, is dominated by exotic plants, and that introduced fish pose a recurrent threat to the native fish of that area. Meanwhile at the Grand Canyon, invasives such as tamarisk, red brome, carp, and catfish are pervasive either in the Colorado River or in the patches of desert scrub along its shores. Throughout the Sonoran Desert and adjacent areas, from islands in the Sea of CortŽs to desert grasslands, some six hundred species of non-native plants and animals have become established, with bullfrogs and Mediterranean grasses now common where they once never existed. The book brings together contributors from academia, government, and nonprofit organizations, including such experts as Gary Paul Nabhan, Richard Mack, and Alberto Bœrquez-Montijo. They review historic and even prehistoric origins of non-native speciesÑnot only exotic plants, amphibians, and mammals but also insects, fish, and birds. They then examine significant problems in each major subregion and ecosystem and discuss control efforts. The volume contains the first compiled list of more than 500 naturalized exotic species in the Sonoran region. Invasive species issues are rapidly emerging as major environmental concerns both locally and worldwide. This book will assist professionalsÑecologists, conservation biologists, and policy makersÑinvolved in invasive species control in the Southwest and will be a rich resource for all concerned with protecting native species and their habitats.
Download or read book Mediterranean Type Ecosystems written by George W. Davis and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human activities are causing species extinctions at a rate and magnitude rivaling those of past geologic extinction events. Exploring mediterranean-type ecosystems - the Mediterranean Basin, California, Chile, Australia, and South Africa - this volume addresses the question whether biological diversity plays a significant role in the functioning of natural ecosystems, and to what extent that diversity can be reduced without causing system malfunction. Comparative studies in ecosystems that are similar in certain respects, but differ in others, offer considerable scope for gaining new insights into the links between biodiversity and ecosystem functioning.

Download or read book The Routledge Handbook of Mechanisms and Mechanical Philosophy written by Stuart Glennan and published by Taylor & Francis. This book was released on 2017-07-06 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientists studying the burning of stars, the evolution of species, DNA, the brain, the economy, and social change, all frequently describe their work as searching for mechanisms. Despite this fact, for much of the twentieth century philosophical discussions of the nature of mechanisms remained outside philosophy of science. The Routledge Handbook of Mechanisms and Mechanical Philosophy is an outstanding reference source to the key topics, problems, and debates in this exciting subject and is the first collection of its kind. Comprising over thirty chapters by a team of international contributors, the Handbook is divided into four Parts: Historical perspectives on mechanisms The nature of mechanisms Mechanisms and the philosophy of science Disciplinary perspectives on mechanisms. Within these Parts central topics and problems are examined, including the rise of mechanical philosophy in the seventeenth century; what mechanisms are made of and how they are organized; mechanisms and laws and regularities; how mechanisms are discovered and explained; dynamical systems theory; and disciplinary perspectives from physics, chemistry, biology, biomedicine, ecology, neuroscience, and the social sciences. Essential reading for students and researchers in philosophy of science, the Handbook will also be of interest to those in related fields, such as metaphysics, philosophy of psychology, and history of science.
