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 Damming Grand Canyon written by Diane E Boyer and published by . This book was released on 2007-05-07 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1923, America paid close attention, via special radio broadcasts, newspaper headlines, and cover stories in popular magazines, as a government party descended the Colorado to survey Grand Canyon. Fifty years after John Wesley Powell's journey, the canyon still had an aura of mystery and extreme danger. At one point, the party was thought lost in a flood. Something important besides adventure was going on. Led by Claude Birdseye and including colorful characters such as early river-runner Emery Kolb, popular writer Lewis Freeman, and hydraulic engineer Eugene La Rue, the expedition not only made the first accurate survey of the river gorge but sought to decide the canyon's fate. The primary goal was to determine the best places to dam the Grand. With Boulder Dam not yet built, the USGS, especially La Rue, contested with the Bureau of Reclamation over how best to develop the Colorado River. The survey party played a major role in what was known and thought about Grand Canyon. The authors weave a narrative from the party's firsthand accounts and frame it with a thorough history of water politics and development and the Colorado River. The recommended dams were not built, but the survey both provided base data that stood the test of time and helped define Grand Canyon in the popular imagination. Also by Robert Webb: Lee's Ferry

Download or read book The Sierra Pinacate written by Julian D. Hayden and published by University of Arizona Press. This book was released on 2023-01-17 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: South of the border, a spectacular range of ancient volcanoes rises from the desert floor just a few miles from the Sea of Cortez. Virtually untraveled, the Sierra Pinacate in northwestern Mexico beckons adventurers and scientists. Here, in words and pictures, is a remarkable introduction to this place of almost surreal beauty. Sometimes veiled in clouds or dust storms, the Pinacate have long been shrouded in mystery as well. From prehistoric times until today, people of Sonora have told tales of giants, men and animals, bottomless pits, endless tunnels, hostile Indians, smoking caverns, and ever-present dangers found in the Pinacate. This book takes readers deep into the heart of this fascinating area. Julian Hayden, who worked and traveled in the Pinacate for four decades, introduces the natural history, archaeology, geology, and human history of the area. Spectacular color photographs by Jack Dykinga capture the magic and the isolation of this stunning region. Hayden's text is presented in both English and Spanish. The Mexican government has already declared the Pinacate an officially protected biosphere reserve; still pending is its inclusion in the Man and the Biosphere program of the United Nations. More than a natural history, The Sierra Pinacate is an elegant appreciation of a place of wonder.
