Download or read book Plant Invasions in Protected Areas written by Llewellyn C. Foxcroft and published by Springer Science & Business Media. This book was released on 2013-11-27 with total page 661 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first comprehensive global review of all aspects of alien plant invasions in protected areas. It provides insights into advances in invasion ecology emanating from work in protected areas, and the link to locally relevant management support for protected areas. The book provides in-depth case studies, illuminating interesting and insightful knowledge that can be shared across the global protected area network. The book includes the collective understanding of 80 ecologists and managers to extract as much information as possible that will support the long-term management of protected areas, and the biodiversity and associated ecosystem services they maintain. “This outstanding volume draws together pretty much all that can be said on this topic, ranging from the science, through policy, to practical action”. Dr. Simon N. Stuart, IUCN Species Survival Commission, UK. "This important and timely volume addresses two of the most serious problems affecting biodiversity conservation today: assessing the extent to which protected areas are impacted by biological invasions and the complex problems of managing these impacts. Written by leading specialists, it provides a comprehensive overview of the issues and gives detailed examples drawn from protected areas across the world". Professor Vernon H. Heywood, School of Biological Sciences, University of Reading, UK
Download or read book Wattles written by David M. Richardson and published by CABI. This book was released on 2023-11-13 with total page 586 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book provides a comprehensive overview of current knowledge about "wattles", a large clade of over 1000 species of trees and shrubs in the genus Acacia, most of which are native to Australia. It examines the biology, ecology, evolution, and biogeography of wattles in their native ranges, including the evolutionary forces that have driven past speciation and adaptation to diverse environments, the conservation status, uses and human perceptions of these species. It considers the different histories of the introductions and proliferation of wattles as alien species in different parts of the world since c. 1850 (the Anthropocene), situated within relevant political, socio-economic and scientific contexts, together with an analysis of how awareness of their impacts as invasive species has changed over time. Differences in the dynamics and trends associated with the introduction, naturalization and invasion of wattles in different parts of the world are reviewed. The book also synthesizes the global distribution of wattles using diverse data sources, alongside trends, patterns and projections of global uses of wattles. It discusses the genetics, biotic interactions, and ecological, economic and social impacts of invasive wattles. This book is aimed at academics and students in the field of ecology, and at managers of natural and anthropic ecosystems, policy-makers and regulators, and the general public interested in biology and environmental science.
Download or read book Global Review of Forests Pests and Diseases written by Food and Agriculture Organization of the United Nations and published by Fao Forestry Papers. This book was released on 2009 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insect pests, diseases and other biotic agents have considerable impacts on forests. They can adversely affect tree growth, vigor and survival, the yield and quality of wood and non-wood products, wildlife habitat, recreation and the aesthetic appeal and cultural value of forests. They may also impede forest plantation programmes and make it necessary to abandon certain tree species or to clear cut large areas dominated by infested trees. This publication represents a rare effort to address forest pests and diseases comprehensively at the global level. Part I summarizes the results of a thematic study reviewing forest pests in 25 countries. Part II presents profiles of some globally important forest pest species, and III discusses select forest trees species and their associated pests. The information provided in this publication will assist forest health specialists, forest managers and policy-makers worldwide to make informed decisions.
Download or read book Quantifying the Ecological Impacts of the Woody Invasive Prosopis Juliflora mesquite in Gantsi District Botswana written by Tshegofatso Chilume and published by . This book was released on 2017 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humans have introduced plants into new areas for centuries. These plants can provide food, shelter and other positive benefits. However, introduced plants become invasive plants when they spread uncontrollably and become destructive by transforming the environment of their invaded areas. This is the case with Prosopis juliflora, a woody invasive plant of Central American origin, introduced into the Kgalagadi Desert in the early 1980s. This introduction has tremendously transformed Kgalagadi Desert, improving both its soil and species richness but it has now invaded the adjacent Gantsi District, a place of high economic and ecological value to Botswana. This study assessed the impacts associated with P. juliflora invasion on soil properties and native plants along Hanahai Valley, in Gantsi District. Species richness, density and composition were evaluated in 20 invaded and 20 uninvaded plots. Soil samples were also collected for a range of chemical analyses. A total of 165 plant species were recorded during this study; 158 species in the uninvaded plots and 132 species in the invaded plots, a difference of 26 species. Analysis of P. juliflora invasion association with species richness and abundance in Gantsi District showed that P. juliflora is associated with significantly reduced evenness, richness and density and an altered community composition of associated plants. The presence of P. juliflora was associated with significant increase in values of soil variables including pH, calcium, nitrogen, potassium, sodium, phosphorus, magnesium and cation exchange capacity. Moverover, P. juliflora invasion was found to be associated with an increase in invasion index and a decline in dominant native species heights. It remains unclear whether the measured differences between invaded and uninvaded plots were a result of P. juliflora invasion or P. juliflora preferentially invading sites with certain soil and vegetation characteristics. These results provide a baseline on the probable impacts associated with the presence of P. juliflora in Gantsi District, and suggest that management and control measures should be put in place before it spreads further and exerts more pressure on the ecosystem.

Download or read book The Birds of Africa Volume VIII written by Roger Safford and published by Bloomsbury Publishing. This book was released on 2020-09-17 with total page 1025 pages. Available in PDF, EPUB and Kindle. Book excerpt: Universally recognised as by far the most authoritative work ever published on the subject, The Birds of Africa is a superb multi-contributor reference work, with encyclopaedic species texts, stunning paintings of all species and numerous subspecies, informative line drawings, detailed range maps, and extensive bibliographies. Each volume contains an Introduction that brings the reader up to date with the latest developments in African ornithology, including the evolution and biogeography of African birds. Diagnoses of the families and genera, often with superspecies maps, are followed by the comprehensive species accounts themselves. These include descriptions of range and status, field characters, voice, general habits, food, and breeding habits. Full bibliographies, acoustic references, and indexes complete this scholarly work of reference. This eighth and final volume covers the Malagasy region which comprises Madagascar and the various islands and archipelagos of the Indian Ocean including the Seychelles, the Comoros, Mauritius and Réunion. Every resident and migrant species is covered in full detail, comparable to other volumes in the series, and with a colour map for each species. Vagrants are treated in less detail. All species are illustrated on a beautiful series of 64 colour plates, with original artwork from John Gale and Brian Small. This is a major work of reference on the birds of the region and will remain the standard text for many years to come.

Download or read book The Biology of Island Floras written by David Bramwell and published by Cambridge University Press. This book was released on 2011-07-21 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oceanic islands offer biologists unparalleled opportunities to study evolutionary processes and ecological phenomena. However, human activity threatens to alter or destroy many of these fragile ecosystems, with recent estimates suggesting that nearly half of the world's insular endemics are threatened with extinction. Bringing together researchers from around the world, this book illustrates how modern research methods and new concepts have challenged accepted theories and changed our understanding of island flora. Particular attention is given to the impact of molecular studies and the insights that they provide into topics such as colonisation, radiation, diversification and hybridisation. Examples are drawn from around the world, including the Hawaiian archipelago, Galapagos Islands, Madagascar and the Macronesian region. Conservation issues are also highlighted, with coverage of alien species and the role of ex situ conservation providing valuable information that will aid the formulation of management strategies and genetic rescue programmes.
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.
