Download or read book Alien and Invasive Animals written by Mike Picker and published by Penguin Random House South Africa. This book was released on 2013-10-24 with total page 635 pages. Available in PDF, EPUB and Kindle. Book excerpt: While alien plants have been well publicised, this is the first book to be published on alien animals of Africa. It describes the history of each invasion, and the ecological and economic impacts in South Africa; and it discusses the effect of introduced biocontrol agents (usually insects), which are also alien species released deliberately to control problem plants. Key features are: • Each group of animals is covered in a separate chapter written by a specialist in the field • Colour photographs of each species • Maps for each species’ native and introduced range, and a detailed map of its spread in South Africa • Text covers identification and biology, distribution, impacts and control for the particular species • Alien animals are considered in all habitats, including freshwater, terrestrial and marine. The book will be an essential reference for conservationists, farmers, reserve managers, gardeners, anglers, biology students and researchers, and of interest to the lay public.

Available in PDF, EPUB and Kindle. Book excerpt: Aldo Leopold was known to advocate a love of sport as a catalyst for conservation, and his own preference was the sport of fly fishing. But fly fishing is not just a religious or spiritual endeavour. It is also a sport essential to the conservation movement. No fly fisherman wishes to wade into rivers full of stormwater, to cast for invasive Asian carp. Freshwater anglers have been foundational to the preservation and management of freshwater fisheries and waters for centuries. To Leopold s land ethic, fly fishing adds an aquatic vitality. Surveys of fly fishing culture reveal that the sport ranks among the highest for experiences of nature and understanding of ecology. So, it s not surprising that fly fishing, and organizations like Trout Unlimited, has influenced fisheries management, conservation, and restoration in coldwater systems across the world. Backcasts reels these important topics in by exploring the intersection of conservation and fly fishing, in its history, present, and potential future."
Download or read book Ecoagriculture written by Future Harvest and published by Island Press. This book was released on 2012-09-26 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although food-production systems for the world's rural poor typically have had devastating effects on the planet's wealth of genes, species, and ecosystems, that need not be the case in the future. In Ecoagriculture, two of the world's leading experts on conservation and development examine the idea that agricultural landscapes can be designed more creatively to take the needs of human populations into account while also protecting, or even enhancing, biodiversity. They present a thorough overview of the innovative concept of "ecoagriculture" - the management of landscapes for both the production of food and the conservation of wild biodiversity. The book: examines the global impact of agriculture on wild biodiversity describes the challenge of reconciling biodiversity conservation and agricultural goals outlines and discusses the ecoagriculture approach presents diverse case studies that illustrate key strategies explores how policies, markets, and institutions can be re-shaped to support ecoagriculture While focusing on tropical regions of the developing world -- where increased agricultural productivity is most vital for food security, poverty reduction, and sustainable development, and where so much of the world's wild biodiversity is threatened -- it also draws on lessons learned in developed countries. Dozens of examples from around the world present proven strategies for small-scale, low-income farmers involved in commercial production. Ecoagriculture explores new approaches to agricultural production that complement natural environments, enhance ecosystem function, and improve rural livelihoods. It features a wealth of real-world case studies that demonstrate the applicability of the ideas discussed and how the principles can be applied, and is an important new work for policymakers, students, researchers, and anyone concerned with conserving biodiversity while sustaining human populations.
Download or read book Biological Invasions in South Africa written by Brian W. van Wilgen and published by Springer Nature. This book was released on 2020-03-10 with total page 972 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access volume presents a comprehensive account of all aspects of biological invasions in South Africa, where research has been conducted over more than three decades, and where bold initiatives have been implemented in attempts to control invasions and to reduce their ecological, economic and social effects. It covers a broad range of themes, including history, policy development and implementation, the status of invasions of animals and plants in terrestrial, marine and freshwater environments, the development of a robust ecological theory around biological invasions, the effectiveness of management interventions, and scenarios for the future. The South African situation stands out because of the remarkable diversity of the country, and the wide range of problems encountered in its varied ecosystems, which has resulted in a disproportionate investment into both research and management. The South African experience holds many lessons for other parts of the world, and this book should be of immense value to researchers, students, managers, and policy-makers who deal with biological invasions and ecosystem management and conservation in most other regions.

Download or read book African Water Resource Database Concepts and application case studies Spatial analysis for inland aquatic resource management written by Jeff Jenness and published by Food & Agriculture Org.. This book was released on 2007 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: The African Water Resource Database (AWRD) is a set of data and custom-designed tools, combined in a geographic information system (GIS) analytical framework, aimed at facilitating responsible inland aquatic resource management with a focus on inland fisheries and aquaculture. It thus provides a valuable instrument to promote food security. The AWRD data archive includes an extensive collection of datasets covering the African continent, including: surface waterbodies, watersheds, aquatic species, rivers, political boundaries, population density, soils, satellite imagery and many other physiographic and climatological data. This technical paper is the first of two publications about the AWRD, and it gives a general overview addressed both to administrators and managers, as well as for professionals in technical fields. The second part of this technical paper is available separately (ISBN 9789251056479).
Download or read book Alien Reptiles and Amphibians written by Fred Kraus and published by Springer Science & Business Media. This book was released on 2008-12-19 with total page 571 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transportation of species to areas outside their native ranges has been a feature of human culture for millennia. During this time such activities have largely been viewed as beneficial or inconsequential. However, it has become increasingly clear that human-caused introductions of alien biota are an ecological disruption whose consequences rival those of better-known insults like chemical pollution, habitat loss, and climate change. Indeed, the irreversible nature of most alien-species int- ductions makes them less prone to correction than many other ecological problems. Current reshuffling of species ranges is so great that the present era has been referred to by some as the “Homogocene” in an effort to reflect the unique mag- tude of the changes being made. These alien interlopers often cause considerable ecological and economic d- age where introduced. Species extinctions, food-web disruptions, community alte- tions, ecosystem conversion, changes in nutrient cycling, fisheries collapse, watershed degradation, agricultural loss, building damage, and disease epidemics are among the destructive – and frequently unpredictable – ecological and economic effects that invasive alien species can inflict. The magnitude of these damages c- tinues to grow, with virtually all environments heavily used by humans now do- nated by alien species and many “natural” areas becoming increasingly prone to alien invasion as well. Attention to this problem has increased in the past decade or so, and efforts to prevent or limit further harm are gaining wider scientific and political acceptance.
Download or read book Biological Invasions in Marine Ecosystems written by Gil Rilov and published by Springer Science & Business Media. This book was released on 2008-11-12 with total page 642 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological invasions are considered to be one of the greatest threats to the integrity of most ecosystems on earth. This volume explores the current state of marine bioinvasions, which have been growing at an exponential rate over recent decades. Focusing on the ecological aspects of biological invasions, it elucidates the different stages of an invasion process, starting with uptake and transport, through inoculation, establishment and finally integration into new ecosystems. Basic ecological concepts - all in the context of bioinvasions - are covered, such as propagule pressure, species interactions, phenotypic plasticity, and the importance of biodiversity. The authors approach bioinvasions as hazards to the integrity of natural communities, but also as a tool for better understanding fundamental ecological processes. Important aspects of managing marine bioinvasions are also discussed, as are many informative case studies from around the world.

Download or read book Rocky Shores Exploitation in Chile and South Africa written by W. Roy Siegfried and published by Springer Science & Business Media. This book was released on 2013-03-07 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: It seems almost trite to introduce this book by saying that man has been exploiting the intertidal zone for food for a long time. Just how long nobody knows for sure but the prehistoric inhabitants of Terra Amata, on the Mediterranean coast near Nice, ate marine intertidal animals at least 300 000 years ago. Similar impressive evidence, going back to at least 100000 years, exists for prehistoric man's consumption of intertidal animals along the South African coast. However, early man's dependence on intertidal resources probably goes back much further in time. During the last 2 million or so years temperate Eurasia experienced some 20 glaciations interspersed by warm equable periods. Different modes of life were open to man in colonizing the northern temperate zone. One was to become a "big-game" hunter, specializing, for example, on mammoths, the other to exploit marine intertidal resources. Of the two, probably the shoreline offered an easier environment for an original scavenging food-gatherer.

Download or read book Freshwater Fisheries Ecology written by John F. Craig and published by John Wiley & Sons. This book was released on 2015-09-11 with total page 913 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inland fisheries are vital for the livelihoods and food resources of humans worldwide but their importance is underestimated, probably because large numbers of small, local operators are involved. Freshwater Fisheries Ecology defines what we have globally, what we are going to lose and mitigate for, and what, given the right tools, we can save. To estimate potential production, the dynamics of freshwater ecosystems (rivers, lakes and estuaries) need to be understood. These dynamics are diverse, as are the earths freshwater fisheries resources (from boreal to tropical regions), and these influence how fisheries are both utilized and abused. Three main types of fisheries are illustrated within the book: artisanal, commercial and recreational, and the tools which have evolved for fisheries governance and management, including assessment methods, are described. The book also covers in detail fisheries development, providing information on improving fisheries through environmental and habitat evaluation, enhancement and rehabilitation, aquaculture, genetically modified fishes and sustainability. The book thoroughly reviews the negative impacts on fisheries including excessive harvesting, climate change, toxicology, impoundments, barriers and abstractions, non-native species and eutrophication. Finally, key areas of future research are outlined. Freshwater Fisheries Ecology is truly a landmark publication, containing contributions from over 100 leading experts and supported by the Fisheries Society of the British Isles. The global approach makes this book essential reading for fish biologists, fisheries scientists and ecologists and upper level students in these disciplines. Libraries in all universities and research establishments where biological and fisheries sciences are studied and taught should have multiple copies of this hugely valuable resource. About the Editor John Craig is Editor-in-Chief of the Journal of Fish Biology and has an enormous range of expertise and a wealth of knowledge of freshwater fishes and their ecology, having studied them around the globe, including in Asia, North America, Africa, the Middle East and Europe. His particular interests have been in population dynamics and life history strategies. He is a Fellow of the Linnean Society of London and the Royal Society of Biology.
