Download or read book Biomonitors and Biomarkers as Indicators of Environmental Change 2 written by Frank M. Butterworth and published by Springer Science & Business Media. This book was released on 2001-01-31 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: Monitoring the environment is absolutely essential if we are to identify hazards to human health, to assess environmental cleanup efforts, and to prevent further degradation of the ecosystem. Biomonitors and biomarkers combined with chemical monitoring offer the only approach to making these assessments. Based on an International Association of Great Lakes Research conference, this book is intended for researchers who want to incorporate new and different technologies in their development of specifically-crafted monitors; students who are learning the field of biomonitoring; and regulatory agencies that want to consider newer technologies to replace inadequate and less powerful test regimes.

Download or read book Hydrothermal Processes and Mineral Systems written by Franco Pirajno and published by Springer Science & Business Media. This book was released on 2008-10-14 with total page 1250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrothermal processes on Earth have played an important role in the evolution of our planet. These processes link the lithosphere, hydrosphere and biosphere in continuously evolving dynamic systems. Terrestrial hydrothermal processes have been active since water condensed to form the hydrosphere, most probably from about 4.4 Ga. The circulation of hot aqueous solution (hydrothermal systems) at, and below, the Earth’s surface is ultimately driven by magmatic heat. This book presents an in-depth review of hydrothermal proceses and systems that form beneath the oceans and in intracontinental rifts, continental margins and magmatic arcs. The interaction of hydrothermal fluids with rockwalls, the hydrophere and the biophere, together with changes in their composition through time and space, contribute to the formation of a wide range of mineral deposit types and associated wallrock alteration. On Earth, sites of hydrothermal activity support varied ecosystems based on a range of chemotrophic microorganisms both at surface and in the subsurface. This book also provides an overview of hydrothermal systems associated with meteorite impacts and explores the possibility that hydrothermal processes operate on other terrestrial planets, such as Mars, or satellites of the outer planets such as Titan and Europa. Possible analogues of extraterrestrial putative hydrothermal processes pose the intriguing question of whether primitive life, as we know it, may exist or existed in these planetary bodies. Audience: This volume will be of interest to scientists and researchers in geosciences and life sciences departments, as well as to professionals and scientists involved in mining and mineral exploration.

Download or read book The Turtles of Mexico written by John Legler and published by Univ of California Press. This book was released on 2013-08-28 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Turtles of Mexico is the first comprehensive guide to the biology, ecology, evolution, and distribution of more than fifty freshwater and terrestrial turtle taxa found in Mexico. Legler and Vogt draw on more than fifty years of fieldwork to elucidate the natural history of these species. The volume includes an extensive introduction to turtle anatomy, taxonomy, phylogeny, biogeography, and physiology. A key to the turtles of Mexico is included along with individual species accounts featuring geographic distribution maps and detailed color illustrations. Specific topics discussed for each species include habitat, diet, feeding behavior, reproduction, predators, parasites, growth and ontogeny, sexual dimorphism, growth rings, economic use, conservation, legal protection, and taxonomic studies. This book is a complete reference for scientists, conservationists, and professional and amateur enthusiasts who wish to study Mexican turtles.

Available in PDF, EPUB and Kindle. Book excerpt: In the late 18th century, Neptunists and Plutonists had controversial opinions about the formation of the Earth and its lithological units. The former believed that rocks formed from the crystallization of minerals in the early Earth's oceans, the latter believed that rocks were formed in fire. Both theories ignored the importance of continuous wat

Download or read book Defending the Land of the Jaguar written by Lane Simonian and published by University of Texas Press. This book was released on 1995 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mexican conservationists have sometimes observed that it is difficult to find a country less interested in the conservation of its natural resources than is Mexico. Yet, despite a long history dedicated to the pursuit of development regardless of its environmental consequences, Mexico has an equally long, though much less developed and appreciated, tradition of environmental conservation. Lane Simonian here offers the first panoramic history of conservation in Mexico from pre-contact times to the current Mexican environmental movement. He explores the origins of conservation and environmental concerns in Mexico, the philosophies and endeavors of Mexican conservationists, and the enactment of important conservation laws and programs. This heretofore untold story, drawn from interviews with leading Mexican conservationists as well as archival research, will be important reading throughout the international community of activists, researchers, and concerned citizens interested in the intertwined issues of conservation and development.

Download or read book Iguanas written by Dr. Allison C. Alberts and published by Univ of California Press. This book was released on 2004-03-03 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: In what is certain to be the key reference on iguanas for years to come, some of the world's leading experts offer a clear and accessible account of the latest research on the evolution, behavioral ecology, and conservation of these highly visible and increasingly endangered creatures, much loved by professional herpetologists and hobbyists alike. The book begins with an introduction by noted iguana biologist Dr. Gordon Burghardt that examines the state of iguana research—past, present, and future—with an emphasis on social behavior. Three major sections follow, each opening with a synthesis by the volume editors, who survey the current status and likely future direction of investigations in the pertinent area. The first section focuses on different aspects of the taxonomic and morphological diversity of iguanas and includes a complete checklist of species. In the second section, contributors address the behavior and ecology of iguanas and provide compelling evidence that both may be far more complex than previously appreciated. The third and final section, highlighting the threats facing iguana populations today, describes the broad array of innovative conservation strategies that will be needed to help ensure their survival. Illustrated throughout with photographs, distribution maps, tables, and figures, this volume will be the definitive resource for anyone—professional or curious amateur—interested in iguanas.
