Available in PDF, EPUB and Kindle. Book excerpt: Over the past thirty years, late Quaternary environments in the arid interior of western North America have been revealed by a unique source of fossils: well-preserved fragments of plants and animals accumulated locally by packrats and quite often encased, amberlike, in large masses of crystallized urine. These packrat middens are ubiquitous in caves and rock crevices throughout the arid West, where they can lie preserved for tens of thousands of years. More than a thousand of these deposits have been dated and analyzed, and middens have supplanted pollen records as a touchstone for studying vegetation dynamics and climatic change in radiocarbon time (the last 40,000 years). Now, similar deposits made by other mammals like hyraxes are being reported from other parts of the world. This book brings together the findings and views of many of the researchers investigating fossil middens in the United States, Mexico, Africa, the Middle East, and Australia. The contributions serve to open a forum for methodological concerns, update the fossil record of various geographic regions, introduce new applications, and display the vast potential for fossil midden analysis in arid regions worldwide. The findings presented here will serve to foster regional research and to promote general studies devoted to global climate change. Included in the text are more than two hundred charts, photographs, and maps.

Book Terrestrial Vegetation of California 3rd Edition

Download or read book Terrestrial Vegetation of California 3rd Edition written by Michael Barbour and published by Univ of California Press. This book was released on 2007-07-17 with total page 734 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thoroughly revised, entirely rewritten edition of what is the essential reference on California’s diverse and ever-changing vegetation now brings readers the most authoritative, state-of-the-art view of California’s plant ecosystems available. Integrating decades of research, leading community ecologists and field botanists describe and classify California’s vegetation types, identify environmental factors that determine the distribution of vegetation types, analyze the role of disturbance regimes in vegetation dynamics, chronicle change due to human activities, identify conservation issues, describe restoration strategies, and prioritize directions for new research. Several new chapters address statewide issues such as the historic appearance and impact of introduced and invasive plants, the soils of California, and more.

Book Ecology of Sonoran Desert Plants and Plant Communities

Download or read book Ecology of Sonoran Desert Plants and Plant Communities written by Robert H. Robichaux and published by University of Arizona Press. This book was released on 2023-01-17 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Sonoran Desert is a distinctive biotic region that fascinates scientist, students, and nature lovers. This book offers an accessible introduction to Sonoran Desert ecology. Eight original essays by Sonoran Desert specialists provide an overview of the practice of ecology at landscape, community, and organismal scales. The essays explore the rich diversity of plant life in the Sonoran Desert and the ecological patterns and processes that underlie it. They also reveal the history and scientific legacy of the Desert Laboratory in Tucson, which has conducted research on the Sonoran Desert since 1903. Coverage includes diversity and affinities of the flora, physical environments and vegetation, landscape complexity and ecological diversity, population dynamics of annual plants, form and function of cacti, and the relationship between plants and the animals that use them as feeding and breeding resources. The text also examines the ecological consequences of modern agricultural development, as well as the impact on the modern biota of 40,000 years of change in climate, vegetation, megafauna, and ancient cultures. This comprehensive book covers a broad range of spatial and temporal scales to highlight the diversity of research being pursued in the Sonoran Desert. It is both a testament to these ongoing studies and an authoritative introduction to the diverse plant life in the region. Contents 1. Diversity and Affinities of the Flora of the Sonoran Floristic Province, Steven P. McLaughlin and Janice E. Bowers 2. Vegetation and Habitat Diversity at the Southern Edge of the Sonoran Desert, Alberto Bórquez, Angelina Martínez Yrízar, Richard S. Felger, and David Yetman 3.
