Download or read book The Gulf of California written by Richard C. Brusca and published by University of Arizona Press. This book was released on 2010-04-15 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Discovering the Geology of Baja California written by Markes E. Johnson and published by . This book was released on 2002 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Desert Islands of Mexico s Sea of Cortez written by Stewart W. Aitchison and published by University of Arizona Press. This book was released on 2010-11-15 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: The desert islands in the Sea of Cortez are little known except to a few intrepid tourists, sailors, and fishermen. Though at first glance these stark islands may appear barren, they are a refuge for an astounding variety of plants and animals. While many of the species are typical of the greater Sonoran Desert region, some are endemic or unique to one or two islands. For example, Isla Santa Catalina is home to the worldÕs only rattlesnake that has lost its ability to grow a rattle. Other islands host nesting birds, such as Isla Rasa, a tiny, flat flow of basalt lava that attracts nearly half a million elegant and royal terns and HeermannÕs gulls each spring. The Desert Islands of MexicoÕs Sea of Cortez is one of the few books devoted to the biogeography of this remarkable part of the world. The book explores the geologic origin of the gulf and its islands, presents some of the basics of island biogeography, details insular lifeÑincluding residents of the intertidal zone Ñand provides a brief outlook for preserving this area. More than a simple guidebook, AitchisonÕs writing will take both actual and armchair travelers through a gripping tale of natural history. Like the rest of our fragile planet, the Sea of Cortez and its islands are threatened by humans. Overfishing has eliminated or greatly diminished many fish stocks, and dams on rivers that once flowed into the gulf prevent certain nutrients from reaching the sea. The tenuousness of this area makes the bookÕs extraordinary photographs and the firsthand descriptions by a well-known teacher, writer, and photographer all the more compelling.
Download or read book Shells on a Desert Shore written by Cathy Moser Marlett and published by University of Arizona Press. This book was released on 2014-06-12 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Mexico’s western Sonoran Desert along the Gulf of California is a place made extraordinary by the desert solitude, the dynamic sea, and the people who live there—the Seris. Central to the lives of these people are the sea and its shores. Shells on a Desert Shore describes the Seri knowledge of mollusks and includes names, folklore, history, uses, and much more. Cathy Moser Marlett’s research of several decades, conducted in the Seri language, builds on work begun in 1951 by her parents, Edward and Becky Moser. The language, spoken by fewer than a thousand people today, is considered endangered. Marlett presents what she has learned from Seri consultants over recent decades and also draws from her own childhood experiences while living in a Seri village. The information from the people who had lived as hunter-gatherers provides a window into a lifestyle no longer recalled from personal experience by most Seris today—and perhaps a window into the lives of other peoples who made the Gulf’s shores their home. The book offers a wealth of information about Seri history, as well as species accounts of more than 150 mollusks from the Seri area on the central Gulf coast. Chapters describe how the people ate mollusks or used them medicinally, how the mollusks were named, and how their shells were used. The author provides several hundred detailed drawings and photographs, many of them archival. Shells on a Desert Shore is a fresh, original presentation of a significant part of the Seri way of life. Unique because it is written from the perspective of a participant in the Seri culture, the book will stand as a definitive, irreplaceable work in ethnography, a time capsule of the Seri people and their connection to the sea.
Download or read book The Record of Native People on Gulf of California Islands written by Thomas Bowen and published by Arizona State Museum. This book was released on 2009 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last century historians and anthropologists interested in northwestern Mexico knew that Indians had inhabited four large islands in the Gulf of California. Since 1900 ethnohistorical and archaeological research has expanded knowledge of Indians on both sides of the Gulf. Much of that information pertains to the people living on the peninsula and mainland, and touches only incidentally on the islands. In this volume, Thomas Bowen presents historical and archaeological evidence for human use of 32 major Gulf islands. Native people may have played a significant role in shaping island ecosystems. Chronological data from the southern Gulf establishes a time depth for native people of ten millennia. New information from Seri oral history indicates Seri voyages far beyond Isla Tiburón, and Bowen shows the traditional assumption -- that most islands were beyond the range of native people – is wrong. Indians knew and exploited nearly every significant island in the Gulf. Bowen’s work touches on the question of initial human entry into the Americas. The Gulf may occupy a pivotal position in human dispersal in the Americas, and it is possible that evidence of this process has been preserved on some Gulf islands.
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.

Download or read book The California Current written by Stan Ulanski and published by UNC Press Books. This book was released on 2016-02-13 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: The California Current--part of the large, swirling North Pacific gyre--flows slowly southward along the west coast of North America, stretching nearly 2,000 miles from southern British Columbia to the tip of Baja California in Mexico. To a casual observer standing on the shore, the vast current betrays no discernible signs, yet life abounds just over the horizon. Stan Ulanski takes us into the water on a journey through this magnificent, unique marine ecosystem, illuminating the scientific and biological marvels and the astonishing array of flora and fauna streaming along our Pacific coast. The waters of the California Current yield a complex broth of planktonic organisms that form the base of an elaborate food web that many naturalists have compared to the species-rich Serengeti ecosystem of Africa. Every year, turtles, seals, fish, and seabirds travel great distances to feast in the current's distinct biological oases and feeding sites. Apex predators, such as the California gray whale, humpback whale, salmon shark, and bluefin tuna, undertake extensive north-south migrations within the current to find enough to eat. The California Current energizes us to celebrate and protect a marine ecosystem integral to the myriad fisheries, coastal communities, and cultures of the Pacific coast.

Download or read book Understanding and Predicting the Gulf of Mexico Loop Current written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2018-05-23 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most significant, energetic, yet not well understood, oceanographic features in the Americas is the Gulf of Mexico Loop Current System (LCS), consisting of the Loop Current (LC) and the Loop Current Eddies (LCEs) it sheds. Understanding the dynamics of the LCS is fundamental to understanding the Gulf of Mexico's full oceanographic system, and vice versa. Hurricane intensity, offshore safety, harmful algal blooms, oil spill response, the entire Gulf food chain, shallow water nutrient supply, the fishing industry, tourism, and the Gulf Coast economy are all affected by the position, strength, and structure of the LC and associated eddies. This report recommends a strategy for addressing the key gaps in general understanding of LCS processes, in order to instigate a significant improvement in predicting LC/LCE position, evolving structure, extent, and speed, which will increase overall understanding of Gulf of Mexico circulation and to promote safe oil and gas operations and disaster response in the Gulf of Mexico. This strategy includes advice on how to design a long-term observational campaign and complementary data assimilation and numerical modeling efforts.
Download or read book Isle of the Amazons in the Vermilion Sea written by Gregory MacDonald and published by 39 West Press. This book was released on 2019-04-23 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: Myth has it that Baja California was once ruled by a giant queen, Calafia. Her subjects were black Amazon women, and they lived in a land of ferocious griffins, tall mountains, precipitous cliffs, and deep valleys. Baja was also said to be an island of gold and precious stones. Spanish explorers, lured by tales of riches and beautiful women, were drawn to this mythical place. Jesuit priests, adventurers, fishermen, hunters, and the curious soon followed. In Isle of the Amazons in the Vermilion Sea, Gregory MacDonald has assembled a superb collection of excerpts from diaries, letters, field notes, books, and journals. These short impressions give us the sights, smells, sounds, and tastes of mountain hamlets, lush valleys, hot deserts, and blue seas, and together, they create a stunning narrative of the mythology, history, and topology of the Baja land, sea, and people. Montalvo, Cortéz, and Padre Eusebio Kino—in 1400, 1535, and 1701, respectively—describe the flora and fauna of a peninsula untouched by civilization, and in the twentieth century, Bancroft, Cannon, Crosby, Gardner, North, Steinbeck, and Octavio Paz, among others, speak of the fishing, the hunting, and, despite hardships, the pure joy of being. The writers observe fish pileups and feeding-frenzies; suffer insect bites, cactus pricks, and jellyfish stings; and are awed by magical sunsets, the silence of the desert, and the stars. Original illustrations by award-winning printmaker Judith Palmer transform the work into a masterpiece.
