This book was released on 2013-01-31 with total page 623 pages. Available in PDF, EPUB and Kindle. Book excerpt: The desert islands of the Gulf of California are among the world's best-preserved archipelagos. The diverse and unique flora, from the cardón forests of Cholludo to the agave-dominated slopes of San Esteban remain much as they were centuries ago, when the Comcaac (Seri people) were the only human presence in the region. Almost 400 plant species exist here, with each island manifesting a unique composition of vegetation and flora. For thousands of years, climatic and biological forces have sculpted a set of unparalleled desert worlds. Plant Life of a Desert Archipelago is the first in-depth coverage of the plants on islands in the Gulf of California found in between the coasts of Baja California and Sonora. The work is the culmination of decades of study by botanist Richard Felger and recent investigations by Benjamin Wilder, in collaboration with Sr. Humberto Romero-Morales, one of the most knowledgeable Seris concerning the region's flora. Their collective effort weaves together careful and accurate botanical science with the rich cultural and stunning physical setting of this island realm. The researchers surveyed, collected, and studied thousands of plants—seen here in meticulous illustrations and stunning color photographs—providing the most precise species accounts of the islands ever made. To access remote parts of the islands the authors worked directly with the Comcaac, an indigenous community who have lived off marine and terrestrial life in this coastal desert region for centuries. Invaluable information regarding indigenous names and distributions are an intrinsic part of this work. The flora descriptions are extraordinarily detailed and painstakingly crafted for field biologists. Conservationists, students, and others who are interested in learning about the natural wealth of the Gulf of California, desert regions, or islands in general are sure to be captivated by this rich and fascinating volume.

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 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 378 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 annually—and 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 is—or should be—protected. 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 book was released on 2013-05-27 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book provides information essential for anyone interested in the ecology of the American Southwest, including land managers, environmental planners, conservationists, ecologists and students. It is unique in its coverage of the hows and whys of dynamics (changes) in the major types of vegetation occurring on southwestern mountains and plateaus. It explains the drivers and processes of change, describes historical changes and provides conceptual models that diagrammatically illustrate past, present, and potential future changes. All major types of vegetation are covered: spruce-fir, mixed conifer, and ponderosa pine forests, pinyon-juniper vegetation, subalpine-montane grassland, and Gambel oak and interior chaparral shrublands. The focus is on vegetation that is relatively undisturbed, i.e., in natural and near-natural condition, and how it responds to natural disturbances such as fire and drought, as well as to anthropogenic disturbances such as fire exclusion and invasive species

Available in PDF, EPUB and Kindle. Book excerpt: Northwestern Baja California is an area of exceptionally high local endemism, nestled at the southernmost end of the California Floristic Province (CFP), one of the world's mediterranean-climate regions. The ecotonal position between the CFP and the central deserts of the Baja California Peninsula reflects the transition of the major climatic regimes. This area appears to have been more climatically stable than adjacent areas, and the local endemism along the coast is largely the result of the persistent marine layer, which buffers temperature extremes and maintains moisture during the drier months of the year. The driving hypothesis of this dissertation is that long-term climatic stability provided by the cold coastal upwelling of the California Current (driven in turn by the large-scale circulation of the seas) has buffered climatic conditions along the coast, reducing species extinctions and allowing adaptive processes leading to high levels of endemism in the local flora. The high productivity of the coastal upwelling has also had an impact on local plant diversity through the impact of prehistoric shell middens on soil heterogeneity: Ocean deposits (aragonite shells) extracted by indigenous people have added to landscape complexity and increased biological diversity along the coast. Shell middens are scattered along the coast, and idiosyncratically change soil conditions and the resultant plant communities. Shell middens consistently increase native plant diversity, but with very different species compositions, overlapping conservation priorities for archeology and biodiversity. The climate-buffering effect of the coastal currents can be evaluated in the flowering dynamics of the local plant communities: Plant phenology is predominantly controlled by season and available moisture. Fogs dampen seasonality in flowering times and plants flower for longer time periods at the coast, allowing probable mechanisms for speciation. This stability is consistent with the high levels of endemism that can be seen along the coast, and in microclimate effects on phenology along the inland-to-coast gradient. Conservation of coastal habitats in this southern edge of the California Floristic Province is of elevated importance due to the refugium effect of the marine layer, and the presence of archeological sites that increase biodiversity.

Available in PDF, EPUB and Kindle. Book excerpt: The Sonoran Desert, a fragile ecosystem, is under ever-increasing pressure from a burgeoning human population. This ecological atlas of the region's plants, a greatly enlarged and full revised version of the original 1972 atlas, will be an invaluable resource for plant ecologists, botanists, geographers, and other scientists, and for all with a serious interest in living with and protecting a unique natural southwestern heritage. An encyclopedia as well as an atlas, this monumental work describes the taxonomy, geographic distribution, and ecology of 339 plants, most of them common and characteristic trees, shrubs, or succulants. Also included is valuable information on natural history and ethnobotanical, commercial, and horticultural uses of these plants. The entry for each species includes a range map, an elevational profile, and a narrative account. The authors also include an extensive bibliography, referring the reader to the latest research and numerous references of historical importance, with a glossary to aid the general reader. Sonoran Desert Plants is a monumental work, unlikely to be superseded in the next generation. As the region continues to attract more people, there will be an increasingly urgent need for basic knowledge of plant species as a guide for creative and sustainable habitation of the area. This book will stand as a landmark resource for many years to come.
