Book excerpt: The most comprehensive book ever written on leatherback sea turtles. Weighing as much as 2,000 pounds and reaching lengths of over seven feet, leatherback turtles are the world’s largest reptile. These unusual sea turtles have a thick, pliable shell that helps them to withstand great depths—they can swim more than one thousand meters below the surface in search of food. And what food source sustains these goliaths? Their diet consists almost exclusively of jellyfish, a meal they crisscross the oceans to find. Leatherbacks have been declining in recent decades, and some predict they will be gone by the end of this century. Why? Because of two primary factors: human redevelopment of nesting beaches and commercial fishing. There are only twenty-nine index beaches in the world where these turtles nest, and there is immense pressure to develop most of them into homes or resorts. At the same time, longline and gill net fisheries continue to overwhelm waters frequented by leatherbacks. In The Leatherback Turtle, James R. Spotila and Pilar Santidrián Tomillo bring together the world’s leading experts to produce a volume that reveals the biology of the leatherback while putting a spotlight on the conservation problems and solutions related to the species. The book leaves us with options: embark on the conservation strategy laid out within its pages and save one of nature’s most splendid creations, or watch yet another magnificent species disappear.

This book was released on 2004-01-09 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Water Science and Application Series, Volume 9. Groundwater recharge, the flux of water across the water table, is arguably the most difficult component of the hydrologic cycle to measure. In arid and semiarid regions the problem is exacerbated by extremely small recharge fluxes that are highly variable in space and time. --from the Preface Groundwater Recharge in a Desert Environment: The Southwestern United States speaks to these issues by presenting new interpretations and research after more than two decades of discipline-wide study. Discussions ondeveloping environmental tracers to fingerprint sources and amounts of groundwater at the basin scalethe critical role of vegetation in hydroecological processesnew geophysical methods in quantifying channel rechargeapplying Geographical Information System (GIS) models to land surface processescoupling process-based vadose zone to groundwater modeling, and more make this book a significant resource for hydmlogists, biogeoscientists, and geochemists concerned with water and water-related issues in arid and semiarid regions.

Download or read book The Protohistoric Pueblo World A D 1275 1600 written by E. Charles Adams and published by University of Arizona Press. This book was released on 2016-04 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the centuries before the arrival of Europeans, the Pueblo world underwent nearly continuous reorganization. Populations moved from Chaco Canyon and the great centers of the Mesa Verde region to areas along the Rio Grande, the Little Colorado River, and the Mogollon Rim, where they began constructing larger and differently organized villages, many with more than 500 rooms. Villages also tended to occur in clusters that have been interpreted in a number of different ways. This book describes and interprets this period of southwestern history immediately before and after initial European contact, A.D. 1275-1600—a span of time during which Pueblo peoples and culture were dramatically transformed. It summarizes one hundred years of research and archaeological data for the Pueblo IV period as it explores the nature of the organization of village clusters and what they meant in behavioral and political terms. Twelve of the chapters individually examine the northern and eastern portions of the Southwest and the groups who settled there during the protohistoric period. The authors develop histories for settlement clusters that offer insights into their unique development and the variety of ways that villages formed these clusters. These analyses show the extent to which spatial clusters of large settlements may have formed regionally organized alliances, and in some cases they reveal a connection between protohistoric villages and indigenous or migratory groups from the preceding period. This volume is distinct from other recent syntheses of Pueblo IV research in that it treats the settlement cluster as the analytic unit. By analyzing how members of clusters of villages interacted with one another, it offers a clearer understanding of the value of this level of analysis and suggests possibilities for future research. In addition to offering new insights on the Pueblo IV world, the volume serves as a compendium of information on more than 400 known villages larger than 50 rooms. It will be of lasting interest not only to archaeologists but also to geographers, land managers, and general readers interested in Pueblo culture.

Download or read book Geothermal Resources written by R. Bowen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the Arab oil embargo of 1974, it has been clear that the days of almost limitless quantities of low-cost energy have passed. In addition, ever worsening pollution due to fossil fuel consumption, for instance oil and chemical spills, strip mining, sulphur emission and accumulation of solid wastes, has, among other things, led to an increase of as much as 10% in the carbon dioxide content of the atmosphere in this century. This has induced a warming trend through the 'greenhouse effect' which prevents infrared radiation from leaving it. Many people think the average planetary temperatures may rise by 4°C or so by 2050. This is probably true since Antarctic ice cores evidence indicates that, over the last 160000 years, ice ages coincided with reduced levels of carbon dioxide and warmer interglacial episodes with increased levels of the gas in the atmosphere. Consequently, such an elevation of temperature over such a relatively short span of time would have catastrophic results in terms of rising sea level and associated flooding of vast tracts of low-lying lands. Reducing the burning of fossil fuels makes sense on both economic and environmental grounds. One of the most attractive alternatives is geothermal resources, especially in developing countries, for instance in El Salvador where geothermal energy provides about a fifth of total installed electrical power already. In fact, by the middle 1980s, at least 121 geothermal power plants were operating worldwide, most being of the dry steam type.

Download or read book Multiple Origins Uncertain Destinies written by National Research Council and published by National Academies Press. This book was released on 2006-02-23 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Given current demographic trends, nearly one in five U.S. residents will be of Hispanic origin by 2025. This major demographic shift and its implications for both the United States and the growing Hispanic population make Multiple Origins, Uncertain Destinies a most timely book. This report from the National Research Council describes how Hispanics are transforming the country as they disperse geographically. It considers their roles in schools, in the labor market, in the health care system, and in U.S. politics. The book looks carefully at the diverse populations encompassed by the term "Hispanic," representing immigrants and their children and grandchildren from nearly two dozen Spanish-speaking countries. It describes the trajectory of the younger generations and established residents, and it projects long-term trends in population aging, social disparities, and social mobility that have shaped and will shape the Hispanic experience.

Download or read book Clovis Caches written by Bruce B. Huckell and published by UNM Press. This book was released on 2014-05-01 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: “A unique, significant contribution to our maturing studies of the Clovis era.”—Gary Haynes, author of The Early Settlement of North America: The Clovis Era The Paleoindian Clovis culture is known for distinctive stone and bone tools often associated with mammoth and bison remains, dating back some 13,500 years. While the term Clovis is known to every archaeology student, few books have detailed the specifics of Clovis archaeology. This collection of essays investigates caches of Clovis tools, many of which have only recently come to light. These caches are time capsules that allow archaeologists to examine Clovis tools at earlier stages of manufacture than the broken and discarded artifacts typically recovered from other sites. The studies comprising this volume treat methodological and theoretical issues including the recognition of Clovis caches, Clovis lithic technology, mobility, and land use.
