A student-friendly textbook that describes ancient soils, how they may be identified, and their use in paleoenvironmental reconstruction Ancient soils contain vital mineralogical, geochemical, textural, and paleontological information about the continental environments in which they formed. Advances in isotope geochemistry and sequence-stratigraphic models allow evermore detailed reconstructions of environmental change from paleosols, and new insights into such diverse topics as atmospheric chemistry, global change, paleoecology, geobiology and mass extinction. This book educates readers about the field of paleopedology and how it remains a key area of investigation for geologists and environmental scientists seeking to learn about, and reconstruct, the condition and evolution of paleoenvironments. Presented in three sections—Soils and Palesols; Factors in Soil Formation; and Fossil Record of Soils—Soils of the Past: An Introduction to Paleopedology describes the main types of ancient soil, procedures for identifying and studying them, their classification and, most significantly, a wide array of examples of how paleosols have been used for paleoenvironmental reconstruction. The book is an excellent reflection of the current state of knowledge and can be widely adopted over many disciplines. All chapters have been revised and updated to reflect advances in soil science in the last two decades New tables display a wealth of new data added since the 2nd edition published in 2001 New figures have been added and line art has been redrawn to improve clarity and promote understanding References have been updated throughout Soils of the Past, 3rd Edition is written for advanced undergraduates studying paleopedology as part of a degree in geology, environmental science, or physical geography, and for interested professional earth scientists.

The Physical Geography of Southeast Asia examines the complex mosaic of physical environments which comprise Southeast Asia, and the current environmental problems and management practices which have arisen in this part of the world. The book is in three sections. The first section introduces the basic environmental components (geology, landforms, rivers, vegetation, and others) across the entire region. The second section discusses specific environments that are characteristic of this assemblage of continental and maritime landscapes (volcanic islands, coastal environment, granitic terrains, karst, etc.). The third and final section illustrates the ecological relationship between the environment and people (volcanic hazards, urban environment, coastal zone development, coral reefs, and others). The physical environment of Southeast Asia is examined at different levels, covering a world region that ranges from ancient, stable landmasses to dynamic, unstable plate boundaries, from aged, primary rainforests to brash, vibrant, resource-demanding built environments. Southeast Asia has been perceived as a laboratory for studying plate tectonics. It is an assemblage of large river basins, peninsulas and archipelagos, and seas surrounded by islands. It is an area of great physical variations where parts of the physical environment have been significantly degraded anthropogenically, following rapid population growth and development. In large parts of the region, the forms and processes on land and offshore should no longer be seen as entirely natural. As this book repeatedly illustrates, plate tectonics and people are both important contributors to the physical geography of Southeast Asia. The contributors to this volume are distinguished, scholarly, and have a long association with Southeast Asia. The chapters are not only skilfully built on state-of-the-art research findings but also include new material from the on-going research activities of the authors. The book goes beyond being the first comprehensive and detailed volume of the biophysical geography of Southeast Asia in that it also deals with the tropical environment and the relationship between environment and people in a rapidly developing world region.

This volume contains five papers dealing with a wide range of plant, animal, and soil biological topics. Gray and his colleagues describe the origin and spread of the salt marsh grass Spartina anglica. The result of a hybridization at the close of the last century, this genetically uniform species has been extremely successful in its particular niche and has a fascinating biology. Smith stresses the importance of gene-environment interactions in life-history theory in contrast to the resource constraint emphasis of the optimization approach. Experimental approaches to the subject are also discussed. Chanway and his colleagues examine the evidence for the importance of interactions between plants and micro-organisms in the rhizosphere in determining the outcome of plant competition and the establishment of community structure. Despite scarce evidence, real effects meriting further research do seem to exist. Brundrett also deals with an aspect of ecology in the soil. Most plants seem to have mycorrhizal associates and their importance is now widely appreciated. Much has been learned but more research is needed to determine the beneficial or after effects of mycorrhizae in natural systems. Richter and Babar review the diversity of tropical soils. They are in fact much more variable than is often thought, perhaps because too few ecologists are specialists in soils. Clearly, a proper knowledge and understanding of the many soil types is vital to conservation and development work in the tropics. Serves as the fourth volume under new editorial direction Presents a broad range of topical papers in ecology Contains five papers dealing with a wide range of plant, animal, and soil biological topics
