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.

Available in PDF, EPUB and Kindle. Book excerpt: The succulent and Nama-karoo form part of the arid south-western zone of Africa, a vast region of rugged landscapes and low treeless vegetation. Studies of this unique biome have yielded fascinating insights into the ecology of its flora and fauna. This book, originally published in 1999, is the first to synthesise these studies, presenting information on biogeographic patterns and life processes, form and function of animals and plants, foraging ecology, landscape-level dynamics and anthropogenic influences. Detailed analyses of the factors distinguishing the biota of the Karoo from that of other temperate deserts are given and generalisations about semi-arid ecosystems challenged. The ideas expounded, the ecological principles reviewed, and the results presented are relevant to all those working in the extensive arid and semi-arid regions of the world.

Book excerpt: Acacia: Characteristics, Distribution and Uses opens with a chapter describing the wood of A. melanoxylon grown in Portugal in view of determining its technological quality for use in the construction and furniture industry. The characterization includes stem features, wood anatomical characteristics, chemical composition, wood density and mechanical properties.Next, the authors aim to describe and analyze common characteristics among Acacia s.l. species and to trace some parallelisms of their performance throughout several ecosystems that hold such species. It is well-known that Acacia s.l. species have the ability to fix atmospheric nitrogen and may modify soil chemistry and physics by enabling microorganisms/soil fauna to alter the microhabitat beneath the tree, and such characteristics are significant in the recovery of ecosystems.The potential of Acacia mangium, an exotic species, for restoration of a degraded land in Mt. Makiling Forest Reserve (MMFR), Philippines was also examined. Results suggested a general trend of changes in A. mangium plantation which was once a grassland dominated by Imperata cylindrica and Saccharum officinarum. Both (stems ha-1) and basal area (m2 ha-1) increased significantly in 2010-2018 (P=0.001).The authors discuss the way in which NMR spectroscopy applied to the study of gum exudates has become important since the 1990̍s in Venezuela. Analytical and structural studies of 23 species belonging to different genera and families have been reported through the combination of classic methodology for carbohydrates and NMR spectroscopy.The footprints left by evolution in the distribution of characters among current organisms have been one of the main tools in the study of organic evolution. The authors propose that the reconstruction of ancestral character states offers the possibility of knowing the changes suffered by characters in a species throughout evolutionary time.Pollinosis, also known as pollen allergy, hay fever or seasonal allergic rhinitis is one the most common respiratory disorders throughout the world. The inhalation of Acacia pollen is one of the main causes of respiratory allergic diseases in semiarid countries such as Iran, Saudi Arabia, and the United Arab Emirates. This book suggests that the recognition of allergenic components of pollens is essential for component-resolved diagnosis, the design of patient-specific immunotherapy, and the explanation of sensitization mechanisms to various allergens.The authors analyze Acacia-Pseudomyrmex mutualism which includes 15 species of acacias and a group of 10 species of mutualistic ants whose geographical distribution is similar. This relationship is frequently cited as an example of coevolution, a term that has been used to refer to the reciprocal change of interacting species where each of them acts as an agent of natural selection with respect to the other and where the reciprocal selection would result in congruent phylogenies.The concluding chapter characterizes the A. melanoxylon wood pulping performance regarding yield and kappa number as well as the pulp and paper properties. The application of fast spectroscopic technologies for pulp quality determination is also described.

Available in PDF, EPUB and Kindle. Book excerpt: Over millions of years, terrestrial plants have competed for limited resources, defended themselves against herbivores, and resisted a myriad of environmental stresses. These struggles have helped generate more than a quarter million terrestrial plant species, each possessing a unique strategy for success. Yet, as Resource Strategies of Wild Plants demonstrates, the constraints on plant growth are universal enough that a few survival strategies hold true for all seed-producing plants. This book describes the five major strategies of growth for terrestrial plants, details how plants succeed when resources are scarce, delves into the history of research into plant strategies, and resets the foundational understanding of ecological processes. Drawing from recent findings in plant-herbivore interactions, ecosystem ecology, and evolutionary ecology, Joseph Craine explains how plants attain available nutrients, withstand the immense stresses of drying soils, and flourish in the race for light. He shows that the competition for resources has shaped plant evolution in newly discovered ways, while the scarcity of such resources has affected how plants interact with herbivores, wind, fire, and frost. An understanding of the major resource strategies of wild plants remains central to learning about the ecology of plant communities, global changes in the biosphere, methods for species conservation, and the evolution of life on earth.

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.
