Few places in the world can claim such a diversity of species as the Gulf of California (Sea of Cortez), with its 6,000 recorded animal species estimated to be half the number actually living in its waters. So rich are the Gulf's water that over a half-million tons of seafood are taken from them annuallyÑand this figure does not count the wasted by-catch, which would triple or quadruple that tonnage. This timely book provides a benchmark for understanding the Gulf's extraordinary diversity, how it is threatened, and in what ways it isÑor should beÑprotected. In spite of its dazzling richness, most of the Gulf's coastline now harbors but a pale shadow of the diversity that existed just a half-century ago. Recommendations based on sound, careful science must guide Mexico in moving forward to protect the Gulf of California. This edited volume contains contributions by twenty-four Gulf of California experts, from both sides of the U.S.-Mexico border. From the origins of the Gulf to its physical and chemical characteristics, from urgently needed conservation alternatives for fisheries and the entire Gulf ecosystem to information about its invertebrates, fishes, cetaceans, and sea turtles, this thought-provoking book provides new insights and clear paths to achieve sustainable use solidly based on robust science. The interdisciplinary, international cooperation involved in creating this much-needed collection provides a model for achieving success in answering critically important questions about a precious but rapidly disappearing ecological treasure.

This volume focuses on the broad pattern of increasing biodiversity through time, and recurrent events of minor and major ecosphere reorganization. Intense scrutiny is devoted to the pattern of physical (including isotopic), sedimentary and biotic circumstances through the time intervals during which life crises occurred. These events affected terrestrial, lacustrine and estuarine ecosystems, locally and globally, but have affected continental shelf ecosystems and even deep ocean ecosystems. The pattern of these events is the backdrop against which modelling the pattern of future environmental change needs to be evaluated.

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.

Investigating the complex interplay between tectonics and sedimentation is a key endeavor in modern earth science. Many of the world's leading researchers in this field have been brought together in this volume to provide concise overviews of the current state of the subject. The plate tectonic revolution of the 1960's provided the framework for detailed models on the structure of orogens and basins, summarized in a 1995 textbook edited by Busby and Ingersoll. Tectonics of Sedimentary Basins: Recent Advances focuses on key topics or areas where the greatest strides forward have been made, while also providing on-line access to the comprehensive 1995 book. Breakthroughs in new techniques are described in Section 1, including detrital zircon geochronology, cosmogenic nuclide dating, magnetostratigraphy, 3-D seismic, and basin modelling. Section 2 presents the new models for rift, post-rift, transtensional and strike slip basin settings. Section 3 addresses the latest ideas in convergent margin tectonics, including the sedimentary record of subduction intiation and subduction, flat-slab subduction, and arc-continent collision; it then moves inboard to forearc basins and intra-arc basins, and ends with a series of papers formed under compessional strain regimes, as well as post-orogenic intramontane basins. Section 4 examines the origin of plate interior basins, and the sedimentary record of supercontinent formation. This book is required reading for any advanced student or professional interested in sedimentology, plate tectonics, or petroleum geoscience.

Through 25 peer-reviewed essays, scholars from the United States and Mexico delve into the environmental, social, economic, and cultural-historical components of what we call an environmental and tourism paradise - the region of Los Cabos, Baja California Sur. This region is vulnerable precisely because of the strong development pressure generated mainly by the tourism sector. Los Cabos analyzes these problems as an opportunity to contribute to the sustainable development of the region. Also available in Spanish, see Los Cabos: Prospectiva de un Paraíso Natural y Turístico. Published by San Diego State University Press and Institute for Regional Studies of the Californias

Rhodolith beds are recognized internationally as a unique ecosystem, and they are the focus of this interdisciplinary book. These marine beds occur worldwide, from the tropics to the poles, ranging in depth from intertidal to deep subtidal habitats and they are also represented in extensive fossil deposits. In the light of international interest in rhodoliths and maerl concerning their role in coastal ecosystems and with respect to biodiversity, fisheries, and the production of sediment, this book provides the most comprehensive view possible. As readers will discover, rhodoliths/maerl are fundamental to a range of ecological processes, acting as ecosystem engineers including playing key roles in recruitment and providing nursery habitats. Rhodoliths/maerl have been used commercially in some parts of the world, and they are understood to be vulnerable to coastal modifications and human-induced change, and hence their status may serve as an indicator of ecosystem health. Rhodoliths/maerl contribute to global carbon budgets although the extent remains to be evaluated, as do the potential impacts of changing global climates and ocean acidification.

Baja California: wild, desolate, and a treasure-house of geological wonders. Along its ancient shorelines, careful observers can learn much about how the Gulf of California came into existence and what the future of the Baja California peninsula might be. For those who wish to unlock the mysteries of Baja California, geologist Markes Johnson offers the key. He has taken a body of technical research on the geology and paleontology of the region and made it accessible in plain language for anyone who visits the peninsula, whether for study or recreation. His book teaches general concepts in coastal geomorphology and tectonics, as well as the basic geological and natural history of the Gulf of California, in a conversive, intellectually stimulating fashion. Johnson's guide takes the form of six day-long hikes in the area of Punta Chivato on the east coast of the southern Baja California peninsula. Punta Chivato is presented as a microcosm of the entire region; it can enable visitors to better understand major themes in the natural history of the Gulf of California and its geological past. All of the hikes begin at the southeast corner of the Punta Chivato promontory and loop out in different directions. Each circuit is designed to minimize overlap with adjacent hikes and to maximize the visitor's exposure to instructive variations in the landscape. Each chapter features additional reflections on a geologist of another time and place who has advanced the field in a way that elucidates the material covered in that chapter. Through these asides, readers will learn the basic lessons about how geologists read the secrets hidden in landscapes. Discovering the Geology of Baja California invites visitors to these shores to explore not only rocks and fossils but also the continuum of past ecosystems with the ecology of the present. It offers both an unparalleled guide to a remote area and a new understanding of life caught in an endless cycle of change.
