Book excerpt: The Kalahari Transect provides a unique opportunity to investigate the ways in which small-scale vegetation pattern affects the simulation of plant processes in semi-arid savanna ecosystems. Spatial pattern is aggregated for all trees in the vegetation communities at most research sites, with no occurrence of aggregation in trees at the most southern arid site. Lower than expected understory density is observed at the northern and southernmost sites in the transect. The understory density is significantly higher than expected at intermediate sites. The correspondence between maximum vegetation cluster size and the observed transition in scaling behavior of the NDVI mosaic reinforces the hypothesis that observed multi-scaling is related to the structural characteristics of vegetation canopies across the rainfall gradient. Variability in vegetation structure leads to a range of simulated annual productivity within one site (600 mm) that accounts for 110% of the total range in mean simulated productivity across all sites. Simulated productivity at the various scales of aggregation results in similar overall patterns of average NPP for both trees and grasses, but drastically reduced distributions of productivity due to reduced structural heterogeneity. A coupled energy and water balance model is used to simulate the effects of large tree canopies on soil moisture and water stress across a series of sites spanning a regional moisture gradient in southern Africa. Tree canopies serve to reduce soil moisture stress of under canopy vegetation in the middle of the rainfall gradient. At the dry end of the rainfall gradient, the effect of tree canopies on soil moisture is dependent on the amount of yearly rainfall received.

Download or read book The Kalahari Environment written by David Thomas and published by Cambridge University Press. This book was released on 1991-02-21 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an integrated, thorough and up-to-date review of the nature and development of the Kalahari environment, an environment of great ecological and geomorphological diversity. Its complex climatic and geological history and its long association with human societies attempting to utilise its natural resources are aspects of increasing scientific interest. The book has evolved from the authors' own research in the Kalahari, and attempts to provide explanations and answers to some of the many questions raised about this region, ranging from the commonly asked 'is it really a desert?', to more specific and detailed concerns. The interdisciplinary approach will make the book of interest to researchers, lecturers and advanced students in earth sciences, environmental studies, tropical geomorphology and Quaternary science. The extensive bibliography will also make the book a very important source of reference.

Download or read book Dryland Ecohydrology written by Paolo D'Odorico and published by Springer Science & Business Media. This book was released on 2006-01-09 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecohydrology emerges as a new field of research aiming at furthering our understanding of the earth system through the study of the interactions between the water cycle and vegetation. By combining the analysis of biotic and abiotic components of terrestrial ecosystems, this volume provides a synthesis of material on arid and semiarid landscapes, which is currently spread in a number of books and journal articles. The focus on water-limited ecosystems is motivated by their high sensitivity to daily, seasonal, and decadal perturbations in water availability, and by the ecologic, climatic, and economic significance of most of the drylands around the world. Conceived as a tool for scientists working in the area of the earth and environmental sciences, this book presents the basic principles of eco-hydrology as well as a broad spectrum of topics and advances in this research field. The chapters collected in this book have been contributed by authors with different expertise, who work in several arid areas around the World. They describe the various interactions among the biological and physical dynamics in dryland ecosystems, starting from basic processes in the soil-vegetation-climate system, to landscape-scale hydrologic and geomorphic processes, ecohydrologic controls on soil nutrient dynamics, and multiscale analyses of disturbances and patterns.

Download or read book Isoscapes written by Jason B. West and published by Springer Science & Business Media. This book was released on 2009-11-25 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stable isotope ratio variation in natural systems reflects the dynamics of Earth systems processes and imparts isotope labels to Earth materials. Carbon isotope ratios of atmospheric CO2 record exchange of carbon between the biosphere and the atmosphere; the incredible journeys of migrating monarchs is documented by hydrogen isotopes in their wings; and water carries an isotopic record of its source and history as it traverses the atmosphere and land surface. Through these and many other examples, improved understanding of spatio-temporal isotopic variation in Earth systems is leading to innovative new approaches to scientific problem-solving. This volume provides a comprehensive overview of the theory, methods, and applications that are enabling new disciplinary and cross-disciplinary advances through the study of "isoscapes": isotopic landscapes. "This impressive new volume shows scientists deciphering and using the natural isotope landscapes that subtly adorn our spaceship Earth.", Brian Fry, Coastal Ecology Institute, Louisiana State University, USA "An excellent timely must read and must-have reference book for anybody interested or engaged in applying stable isotope signatures to questions in e.g. Anthropology, Biogeochemistry, Ecology, or Forensic Science regarding chronological and spatial movement, changes, or distribution relating to animals, humans, plants, or water.", Wolfram Meier-Augenstein, Centre for Anatomy & Human Identification, University of Dundee, UK "Natural resources are being affected by global change, but exactly where, how, and at what pace? Isoscapes provide new and remarkably precise answers.", John Hayes, Woods Hole Oceanographic Institution, USA "This exciting volume is shaping a new landscape in environmental sciences that is utilizing the remarkable advances in isotope research to enhance and extend the capabilities of the field.", Dan Yakir, Weizmann Institute of Science, Israel
Download or read book The Governance of Rangelands written by Pedro M. Herrera and published by Routledge. This book was released on 2014-10-10 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rangelands are large natural landscapes that can include grasslands, shrublands, savannahs and woodlands. They are greatly influenced by, and often dependent on, the action of herbivores. In the majority of rangelands the dominant herbivores are found in domestic herds that are managed by mobile pastoralists. Most pastoralists manage their rangelands communally, benefitting from the greater flexibility and seasonal resource access that common property regimes can offer. As this book shows, this creates a major challenge for governance and institutions. This work improves our understanding of the importance of governance, how it can be strengthened and the principles that underpin good governance, in order to prevent degradation of rangelands and ensure their sustainability. It describes the nature of governance at different levels: community governance, state governance, international governance, and the unique features of rangelands that demand collective action (issues of scale, ecological disequilibrium and seasonality). A series of country case studies is presented, drawn from a wide spectrum of examples from Africa, the Middle East, Central Asia, Europe and North America. These provide contrasting lessons which are summarised to promote improved governance of rangelands and pastoralist livelihoods.
