Download or read book Atlas of Coastal Ecosystems in the Western Gulf of California written by Markes E. Johnson and published by University of Arizona Press. This book was released on 2009 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Gulf of California is one of the most beautiful places in the world, but it is also important to earth and marine scientists who work far beyond the area. In text and an accompanying CD-ROM with stunning satellite images, this atlas captures the dynamics of natural cycles in the fertility of the Gulf of California that have been in near-continuous operation for more than five million years. The book is designed to answer key questions that link the health of coastal ecosystems with the regionÕs evolutionary history: What was the richness of ÒfossilÓ ecosystems in the Gulf of California? How has it changed over time? Which ecosystems are most amenable to conservation? With an emphasis on the intricate workings of the Gulf, a team of scientists led by Markes E. Johnson and Jorge Ledesma-V‡zquez explores how marine invertebrates such as corals and bivalves, as well as certain algae, contribute to the operation of a vast Òorganic engineÓ that acts as a significant carbon trap. The Atlas reveals that the role of these organisms in the ecology of the Gulf was greatly underestimated in the past. The organisms that live in these environments (or provide the sediments for beaches and dunes) are mass producers of calcium carbonate. Until now, no book has considered the centrality of calcium carbonate production as it functions today across multiple ecosystems and how it has evolved over time. An important work of scholarship that also evokes the regionÕs natural splendor, the Atlas will be of interest to a wide range of scientists, including geologists, paleontologists, marine biologists, ecologists, and conservation biologists.

Hall and published by Geological Society of America. This book was released on 2002 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: Approximately 3000 middle and late Cenozoic nearshore marine molluscan taxa from western California are assigned to six time periods, spanning ~25 m.y. In this interdisciplinary study, western California is palinspastically restored for each of the time periods by backsliding and back-rotating large fault blocks or crustal units. Marine fossil assemblages are assigned to nearshore paleoclimatic regions or water masses within palinspastically restored California. In addition, this volume reveals positive feedback mechanisms between paleolatitudinal changes in sea-surface paleotemperature gradients and changes in the diversity of marine mollusks along the California coast through time; defines "equable" based effective temperatures; and analyzes extinction rates among macroinvertebrate marine taxa from coastal California and the possible causes of these extinctions. The late Paleogene to Neogene faunas reflect an increase in faunal diversity related to strengthened temperature gradients, greater extremes in sea-surface temperatures, reduction in temperateness, and the development of an embayed California coastline.
