The Leatherback Turtle


Book Description

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.




No Life for a Lady


Book Description

When Agnes Morley Cleaveland was born on a New Mexico cattle ranch in 1874, the term "Wild West" was a reality, not a cliché. In those days cowboys didn't know they were picturesque, horse rustlers were to be handled as seemed best on the occasion, and young ladies thought nothing of punching cows and hunting grizzlies in between school terms.




Minerals of Mexico


Book Description

After many years of geographical and bibliographical journeys, William Panczner has completed a project that many of us would have loved to initiate, but did not undertake because of its magnitude and intrinsic complexity. Not since L. Salazar Salinas, who is credited with authoring Bole tin numeros 40 and 41 (lnstituto Geologico de Mexico, 1922, 1923), has an author been able to provide readers with a comprehensive volume containing information that is both authentic and reliable on Mexican mineralogy, mineral species, and localities. This volume is the most complete synthesis about Mexican minerals and their occurrences to date. It is richly illustrated with photographs and drawings, is well documented, and is organized into four sections, making it easy to use and enjoyable to read. The introduction contains an interesting summary of the mining history and the development of mineralogy. It also describes, in a condensed but accurate and stimulating manner, the geography and the mineralogy of the country, dividing it into eleven mineral provinces. The author discusses eight of the more important mining districts in Mexico, which produce fine mineral speci mens. There is also a chronology of historical, geological, and mineralogical events in Mexico. This is followed by a bibliography with over 500 references on the subject.




Groundwater Recharge in a Desert Environment


Book Description

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.




Archaeomineralogy


Book Description

1.1 Prologue What is archaeomineralogy? The term has been used at least once before (Mitchell 1985), but this volume is the first publication to lay down the scientific basis and systematics for this subdiscipline. Students sometimes call an introductory archaeology course "stones and bones." Archaeomineralogy covers the stones component of this phrase. Of course, archaeology consists of a great deal more than just stones and bones. Contemporary archaeology is based on stratigraphy, geomorphology, chronometry, behavioral inferences, and a host of additional disciplines in addition to those devoted to stones and bones. To hazard a definition: archaeomineralogy is the study of the minerals and rocks used by ancient societies over space and time, as implements, orna ments, building materials, and raw materials for ceramics and other processed products. Archaeomineralogy also attempts to date, source, or otherwise char acterize an artifact or feature, or to interpret past depositional alteration of archaeological contexts. Unlike geoarchaeology, archaeomineralogy is not, and is not likely to become, a recognized subdiscipline. Practitioners of archaeomineralogy are mostly geoarchaeologists who specialize in geology and have a strong background in mineralogy or petrology (the study of the origin ofrocks).
