The book represents a multidisciplinary approach to understanding soil–landscape–vegetation relationships and, specifically, the ecophysiology of plant communities developing on sandy soils of very low fertility that are subject to seasonal flooding. It provides an overview of the white sand ecosystems within the Amazon basin, and focuses on the forest and herbaceous (meadows) vegetation growing on the dystrophic sandy soils of the upper Negro and Orinoco river basins. Several chapters describe physiographic aspects of the study area using integrated remote sensing and in situ sampling. By doing so they attain a comprehensive description of the origin and evolution of soils and landscapes, an advanced classification of soils, and a mapping of the geographic distribution of psammophilous vegetation. This volume also provides a phytosociological classification of extensive forested areas, and a detailed description of the structure and diversity of little-known herbaceous formations.It targets professionals in the fields of ecology, ecophysiology, geomorphology, soils, vegetation, and the environmental sciences. The information it offers may be of significant use to researchers, protected area planners, and environmental policy makers.

The Guayana Highlands in northeastern tropical America, rising from lowland rain forests and savannas up to 3000 m elevation, are characterized by ancient tablelands called "tepuis." The peatlands that developed on the tepuis constitute unique and fascinating ecosystems and are the focus of this volume, which starts with an overview of tropical and subtropical peats, followed by an introduction to the geo-ecological features of the Guayana region as a whole, with special emphasis on the diversity of the vegetation cover from lowlands to uplands to highlands. The core subject centers on the properties and dating of the peat deposits and the interpretation of the chronological record in terms of past environmental changes. The well illustrated book will appeal to a broad range of scientists interested in tropical highland peats, including quaternarists, soil scientists, geomorphologists, geographers, geologists, ecologists, botanists, hydrologists, conservationists, and land use planners.

Recognized and advocated as a powerful tool, the role of remote sensing in identifying, mapping, and monitoring soil salinity and salinization will continue to expand. Remote Sensing of Soil Salinization: Impact on Land Management delineates how to combine science and geospatial technologies for smart environmental management. Choose the Right Techniques for the Job An overview of soil salinity assessment using remote sensing technologies, the book describes a variety of sensors, ranging from ground-based to airborne and satellite-borne, and their use in a diversity of geographical regions and environmental settings from coastal to inland saline areas. It provides guidance on how to identify and choose the right remote sensing tools and data sets required based on the purpose of the study and the environmental setting. Organized into three sections, the book covers: Section I: Soil Salinity and Remote Sensing: The Object and the Tool - Focuses on the relationships between the landscape-object salinity and the remote sensing tools Section II: Trends in Mapping Soil Salinity and Monitoring Salinization Using Remote and Proximal Sensing - Provides a variety of case studies dealing with soil salinity mapping and monitoring the process of salinization Section III: Diversity of Approaches to Modeling Soil Salinity and Salinization - Demonstrates the diversity of approaches used in modeling soil salinity and salinization in space and time Combines Fundamentals, the Latest Technology, and Practical Examples The book includes analyses of basic issues of remote detection, such as the spectral behavior of salt types and vegetation influence, and evaluations of currently available remote sensing platforms delineating their advantages and disadvantages. The accompanying CD-ROM provides color images that enhance the mat
