The Eastern San Juan Mountains: Their Geology, Ecology and Human History

Rob Blair, George Bracksieck, "The Eastern San Juan Mountains: Their Geology, Ecology and Human History"
Un....sity Pr... of Col....o | 2011-05-11 | ISBN: 1607320843 | 416 pages | PDF | 6,3 MB

A companion to The Western San Juan Mountains (originally published in 1996), The Eastern San Juan Mountains details the physical environment, biological communities, human history, and points of interest in this rich and diverse mountain system.

A natural division between the eastern and western slopes of the San Juans is the north-south line that runs approximately through Lake City, south of the crossing of the Piedra River by US Highway 160. In this super guidebook, twenty-seven contributors--all experts in their fields--artfully bring the geology, hydrology, animal and plant life, human histories, and travel routes of these eastern slopes to life. Designed to inform researchers, educators, and students about the region's complex systems, The Eastern San Juan Mountains also serves as an informative guidebook to accompany visitors along their travels on the Silver Thread National Scenic Byway, which stretches between South Fork and Lake City.

The Eastern San Juan Mountains deserves a place next to The Western San Juan Mountains on the bookshelf of every naturalist, researcher, resident, educator, student, and tourist seeking a greater understanding of this marvelous place and its history.


Quaternary Glaciations - Extent and Chronology: A Closer Look

J. Ehlers, P.L. Gibbard, P.D. Hughes, "Quaternary Glaciations - Extent and Chronology: A Closer Look" | 2011-08-31 | ISBN: 0444534474 | 1126 pages | PDF | 174 MB

The book presents an up-to-date, detailed overview of the Quaternary glaciations all over the world, not only with regard to stratigraphy but also with regard to major glacial landforms and the extent of the respective ice sheets. The locations of key sites are included. The information is presented in digital, uniformly prepared maps which can be used in a Geographical Information System (GIS) such as ArcView or ArcGIS. The accompanying text supplies the information on how the data were obtained (geomorphology, geological mapping, air photograph evaluation, satellite imagery), how the features were dated (14C, TL, relative stratigraphy) and how reliable they are supposed to be. All references to the underlying basic publications are included. Where controversial interpretations are possible e.g. in Siberia or Tibet, this is pointed out. As a result, the information on Quaternary glaciations worldwide will be much improved and supplied in a uniform digital format. The information on the glacial limits is compiled in digital form by the coordinators of the project, and is available to the readers in the form of CD-ROMs, which are included with the book.

Product Description: Geomorphological Mapping: a professional handbook of techniques and applications is a new book targeted at academics and practitioners who use, or wish to utilise, geomorphological mapping within their work. Synthesising for the first time an historical perspective to geomorphological mapping, field based and digital tools and techniques for mapping and an extensive array of case studies from academics and professionals active in the area. Those active in geomorphology, engineering geology, reinsurance, Environmental Impact Assessors, and allied areas, will find the text of immense value.

* Growth of interest in geomorphological mapping and currently no texts comprehensively cover this topic

* Extensive case studies so that it will appeal to professionals, academics and students (with extensive use of diagrams, potentially colour plates)

* Brings together material on digital mapping (GIS and remote sensing), cartography an data sources with a focus on modern technologies (including GIS, remote sensing and digital terrain analysis)

* Provides readers with summaries of current advances in methodological/technical aspects

* Accompanied by electronic resources for digital mapping (either CD/website)

Evolution: What the Fossils Say and Why It Matters

Donald R. Prothero, Carl Buell, "Evolution: What the Fossils Say and Why It Matters"
C....bia Uni.....ty Pr..s | 2007-10-30 | ISBN: 0231139624 | 408 pages | PDF | 16,7 MB

Over the past twenty years, paleontologists have made tremendous fossil discoveries, including fossils that mark the growth of whales, manatees, and seals from land mammals and the origins of elephants, horses, and rhinos. Today there exists an amazing diversity of fossil humans, suggesting we walked upright long before we acquired large brains, and new evidence from molecules that enable scientists to decipher the tree of life as never before.

The fossil record is now one of the strongest lines of evidence for evolution. In this engaging and richly illustrated book, Donald R. Prothero weaves an entertaining though intellectually rigorous history out of the transitional forms and series that dot the fossil record. Beginning with a brief discussion of the nature of science and the "monkey business of creationism," Prothero tackles subjects ranging from flood geology and rock dating to neo-Darwinism and macroevolution. He covers the ingredients of the primordial soup, the effects of communal living, invertebrate transitions, the development of the backbone, the reign of the dinosaurs, the mammalian explosion, and the leap from chimpanzee to human. Prothero pays particular attention to the recent discovery of "missing links" that complete the fossil timeline and details the debate between biologists over the mechanisms driving the evolutionary process.

Evolution is an absorbing combination of firsthand observation, scientific discovery, and trenchant analysis. With the teaching of evolution still an issue, there couldn't be a better moment for a book clarifying the nature and value of fossil evidence. Widely recognized as a leading expert in his field, Prothero demonstrates that the transformation of life on this planet is far more awe inspiring than the narrow view of extremists.

Driving evolution forward, the Earth's physical environment has challenged the very survival of organisms and ecosystems throughout the ages. With a fresh new perspective, Evolution on Planet Earth shows how these physical realities and hurdles shaped the primary phases of life on the planet. The book's thorough coverage also includes chapters on more proximate factors and paleoenvironmental events that influenced the diversity of life. A team of notable ecologists, evolutionary biologists, and paleontologists join forces to describe drifting continents, extinction events, and climate change -- important topics that continue to shape Earth's inhabitants to this very day. In a world where global change has become an international issue, this book provides a several billion-year evolutionary perspective on what the environment and environmental change means to life.

This encyclopedia covers major areas of science including: biology, genetics, microbiology, astronomy, chemistry, physics, engineering, technology, geology, weather, archaeology, psychology, mathematics, and medicine, and provides readers with a wide range of up-to-date, relevant, and accurate information. Now there is a reference that fills the gap for science materials written at a level between the highly technical and introductory sources currently available. This 6-vol. set covers all major areas of science, engineering, technology, as well as mathematics and the medical and health sciences, while providing a comprehensive overview of current scientific knowledge and technology. Consisting of alphabetically-arranged entries, it provides a user-friendly format that makes the broad scope of information easy to access and decipher. Entries typically describe scientific concepts, provide overviews of scientific areas and, in some cases, define terms. Longer entries conclude with a bibliography.
