Book excerpt: This book is a part of the Sabkha Ecosystems series which was designed to provide information on sabkha ecosystems of different regions and to add to the collective knowledge available about saline ecosystems. The comprehensive coverage assists the reader gaining a thorough understanding of sabkha geology, hydrology, geomorphology, zoology, botany, ecology and ecosystem functioning, as well as sabkha conservation, utilization and development. Volume I focused on The Arabian Peninsula and Adjacent Countries, volume II was based on describing saline ecosystems of West and Central Asia , volume III referred to Africa and Southern Europe, while volume IV focused on Cash Crop Halophyte and Biodiversity Conservation. The present volume V focuses on Americans.

Download or read book Evolution of Desert Biota written by David W. Goodall and published by University of Texas Press. This book was released on 2014-07-09 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written by specialists in the field, the papers in this volume explore evolution of animals and plants on the deserts of North America, South America, and Australia. Together, the articles constitute a complete survey of the geological history of the deserts of three continents, the evolution of the animals and plants of those deserts, and their adaptations to the environments in which they live. The first paper, by Otto T. Solbrig, discusses the flora of the South American temperate and semidesert regions, citing numerous genera and reasons that they are found in the different areas. John S. Beard uses the same approach in his discussion of the evolution of Australian desert plants and focuses on western Australian areas. Guillermo Sarmiento appraises the evolution of arid vegetation in tropical America, including the Lesser Antilles and the Coast Range of Venezuela and Colombia. A. R. Main surveys the adaptation of Australian vertebrates to desert conditions and gives examples of how various species of birds, reptiles, and amphibians adapt to their environment in order for the greatest number to survive. James A. MacMahon designates specific communities in the Mojave, Sonoran, and Chihuahuan deserts and discusses the similarity of species of the North American desert mammal faunas found there, while Bobbi S. Low focuses on the evolution of amphibian life histories in the desert and compiles a lengthy table of amphibia comparing egg size, habitat, number of eggs per clutch, and so forth. Finally, W. Frank Blair treats adaptation of anurans to equivalent desert scrub of North and South America and cites various species of frogs and toads that are found in similar areas. The volume also includes an introduction by the editor and an index. Evolution of Desert Biota is the result of a symposium held during the First International Congress of Systematic and Evolutionary Biology in Boulder, Colorado; in August 1973.
Download or read book Ice Age Southern Andes written by C.J. Heusser and published by Elsevier. This book was released on 2003-11-12 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Southern Andes, stretching from the subtropics to the subantarctic, are ideally located for palaeoenvironmental research. Over the broad and continuous latitudinal extent of the cordillera (-24˚), vegetation is adjusted to climatic gradients and atmospheric circulation patterns.Opposed to the prevailing Southern Westerlies, the Southern Andes are positioned to receive the brunt of the winds, while biota are set to record the shifting of incoming storm systems over time. Sequential, latitudinally-placed, sedimentary deposits containing microfossils and macroremains, as archives of past vegetation and climate, make possible the detection of equatorward and poleward displacement of plant communities and, as a consequence, changes in climatic controls. No terrestrial setting in the Southern Hemisphere is so unique for palaeoenvironmental reconstruction during and since the last ice age. Twenty radiocarbon-dated fossil pollen and spore records chosen to place emphasis on the last ice age include high-resolution, submillennial data sets that also cover the Holocene, thus providing contrast between present interglacial and past glacial ages. From a refined data base, the records constitute the foundation for interpreting factors responsible for vegetation change over >50,000 14C years, glacial-interglacial migration and refugial patterns for a diversity of taxa, and the extent of intrahemispheric and polar hemispheric synchroneity versus asynchroneity.

Download or read book The Biology and Utilization of Shrubs written by Cyrus McKell and published by Elsevier. This book was released on 2012-12-02 with total page 677 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Biology and Utilization of Shrubs brings together the wide range of information about shrubs from many disciplines and world locations. The book is organized into seven parts. Part I describes the major shrublands found on each of the vegetated continents. It provides an overview of the dominant shrubland types as well as the associated features of soil and climate that influence the geographic distribution of major shrub species. Part II discusses environmental influences and plant responses. Part III considers the range of genetic diversity for important traits and how these may vary in different habitats. Part IV discusses the effects of stress on physiological processes of shrubs, and the kinds of strategies shrubs employ to meet physiological stress. Part V offers evidence to support the claim that the many virtues of shrubs provide a basis for sustaining shrub use for livestock fodder, wildlife habitat, reclamation and erosion control, fuel, and naturalized landscaping. Part VI outlines methods for collecting and processing seeds from natural stands or from superior genotypes planted in seed production orchards. Part VII describes cultural adaptation to shrub use in a livestock-dominated primitive culture, followed by a detailed economic analysis of establishing shrub plantations to improve livestock production.
Download or read book Climate Variability Impacts on Land Use and Livelihoods in Drylands written by Mahesh K. Gaur and published by Springer. This book was released on 2017-08-30 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited volume is devoted to the examination of the implications of the inevitable changes wrought by global change on the welfare and livelihoods of tens of millions of people who live in dryland regions. Global change is more than just climate change and the ramifications of changing trade patterns (geopolitical and economic aspects), the shift to the market economy, demographic factors (population growth, urbanization and re-settlement), receive attention here. Land use change specialists, policy makers and natural resource management agencies will find the book very useful. Chapters focus on examples that are drawn from a number of sources including previously unpublished studies on the impact of climate change, markets and economics on pastoralist and dryland farming households. The key focus is to provide readers with insights into the real world implications of change (including an analysis of the drivers of change) on these vulnerable groups within dryland societies. The role of humans as agents of these changes is canvassed. A regional analysis of the world's drylands is also performed including those in Australia, Argentina, India, North America, China, North Africa, Central Asia and Southern Africa.
