Available in PDF, EPUB and Kindle. Book excerpt: Ancient DNA refers to DNA which can be recovered and analyzed from clinical, museum, archaeological and paleontological specimens. Ancient DNA ranges in age from less than 100 years to tens of millions of years. The study of ancient DNA is a young field, but it has been revolutionized by the application of polymerase chain reaction technology, and interest is growing very rapidly. Fields as diverse as evolution, anthropology, medicine, agriculture, and even law enforcement have quickly found applications in the recovery of ancient DNA. This book contains contributions from many of the "first generation" researchers who pioneered the development and application of ancient DNA methods. Their chapters present the protocols and precautions which have resulted in the remarkable results obtained in recent years. The range of subjects reflects the wide diversity of applications that are emerging in research on ancient DNA, including the study of DNA to analyze kinship, recovery of DNA from organisms trapped in amber, ancient DNA from human remains preserved in a variety of locations and conditions, DNA recovered from herbarium and museum specimens, and DNA isolated from ancient plant seeds or compression fossils. Ancient DNA will serve as a valuable source of information, ideas, and protocols for anyone interested in this extraordinary field.
Book Synopsis The Freezing Season by : G. Norman Lippert
Download or read book The Freezing Season written by G. Norman Lippert and published by CreateSpace. This book was released on 2015-08-24 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ashley is a young woman broken by choices- some her own, some not. Looking to escape the haunting grip of her past, she embarks on a several-state winter road trip only to pass a sight that changes her life completely: jutting from a dirty snow bank, a small human hand holds its palm up to the sky. Driven by an uncharacteristic need for redemption, Ashley returns to investigate. There, she encounters a seemingly helpful, if disturbed local man and the county sheriff. It isn't until the sheriff begins to question Ashley that the terror of her situation dawns: the body in the snow isn't a snowplow accident, but a murder victim, and by coming back to investigate, Ashley has placed herself directly in the serial killers' path. As the next twenty-two hours unfold, Ashley is confronted with a terrible choice: take advantage of her one chance for escape, or attempt rescue of the killers' last remaining victim, possibly sacrificing herself in the process. Only by embracing the ghosts of her past will Ashley survive her descent into the disturbing madness of the freezing season.

Book Synopsis Glacial Environments by : M. J. Hambrey
Download or read book Glacial Environments written by M. J. Hambrey and published by UBC Press. This book was released on 1994 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Enhanced by many photographic illustrations of extraordinaryquality, this textbook will provide students with a completeintroduction to the scientific study of environments dominated by snowand ice. Glacial environments are scenically and scientifically amongthe most exciting on Earth, and at the same time they are among themost complex. Apart from the processes associated directly with movingice, other processes -- fluvial, acolian, lacustrine, and marine --frequently interact with ice. Glacial environments therefore exhibit awide variety of landforms and sediment associations. Today, some ten per cent of the land surface of the Earth is coveredby ice, whereas in the Pleistocene the figure exceeded thirty per cent.In earlier geological history, the Earth underwent glaciations ofcontinent-wide extent on several occasions, some of them even moreintense than those of the Pleistocene. By examining the processesoperating within glacial settings and their resulting products,Glacial Environments provides the foundation for investigationof both the ancient and the modern record. Emphasizing the range of erosional and depositional landforms,drawing on the older geological record, according due attention to theexciting recent developments in research on the marine environment,incorporating illustrations from both contemporary and ancientenvironments and covering all relevant parts of the world, thisattractive book will find a wide readership among students ofgeography, geology and environmental science.

Book Synopsis Ecological Regions of North America by :
Download or read book Ecological Regions of North America written by and published by . This book was released on 1997 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume represents a first attempt at holistically classifying and mapping ecological regions across all three countries of the North American continent. A common analytical methodology is used to examine North American ecology at multiple scales, from large continental ecosystems to subdivisions of these that correlate more detailed physical and biological settings with human activities on two levels of successively smaller units. The volume begins with an overview of North America from an ecological perspective, concepts of ecological regionalization. This is followed by descriptions of the 15 broad ecological regions, including information on physical and biological setting and human activities. The final section presents case studies in applications of the ecological characterization methodology to environmental issues. The appendix includes a list of common and scientific names of selected species characteristic of the ecological regions.

Book Synopsis Late Glacial and Postglacial Environmental Changes by : Ireneo Peter Martini
Download or read book Late Glacial and Postglacial Environmental Changes written by Ireneo Peter Martini and published by Oxford University Press, USA. This book was released on 1997 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book of contributed papers reconstructs events following the major Paleozoic glaciation, using as analog events during the last 18,000 years. The detailed analysis of present environments aids in understanding what triggered the ancient deglaciations; conversely, the study of the ancient geological record helps to identify factors that influence global environmental change. The syntheses and analyses of Quaternary and older glacial products and events foster a better understanding of those periods in which rapid climatic and environmental changes occurred, and they constitute a ready source of information for analyzing other ancient geological records or constructing models for possible future changes.
Book Synopsis Late Pleistocene and Holocene Environmental Change on the Olympic Peninsula, Washington by : Daniel G. Gavin
Download or read book Late Pleistocene and Holocene Environmental Change on the Olympic Peninsula, Washington written by Daniel G. Gavin and published by Springer. This book was released on 2016-09-10 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study brings together decades of research on the modern natural environment of Washington's Olympic Peninsula, reviews past research on paleoenvironmental change since the Late Pleistocene, and finally presents paleoecological records of changing forest composition and fire over the last 14,000 years. The focus of this study is on the authors’ studies of five pollen records from the Olympic Peninsula. Maps and other data graphics are used extensively. Paleoecology can effectively address some of these challenges we face in understanding the biotic response to climate change and other agents of change in ecosystems. First, species responses to climate change are mediated by changing disturbance regimes. Second, biotic hotspots today suggest a long-term maintenance of diversity in an area, and researchers approach the maintenance of diversity from a wide range and angles (CITE). Mountain regions may maintain biodiversity through significant climate change in ‘refugia’: locations where components of diversity retreat to and expand from during periods of unfavorable climate (Keppel et al., 2012). Paleoecological studies can describe the context for which biodiversity persisted through time climate refugia. Third, the paleoecological approach is especially suited for long-lived organisms. For example, a tree species that may typically reach reproductive sizes only after 50 years and remain fertile for 300 years, will experience only 30 to 200 generations since colonizing a location after Holocene warming about 11,000 years ago. Thus, by summarizing community change through multiple generations and natural disturbance events, paleoecological studies can examine the resilience of ecosystems to disturbances in the past, showing how many ecosystems recover quickly while others may not (Willis et al., 2010).
Book Synopsis Climate Changes in the Holocene: by : Eustathios Chiotis
Download or read book Climate Changes in the Holocene: written by Eustathios Chiotis and published by CRC Press. This book was released on 2018-11-15 with total page 658 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights climate as a complex physical, chemical, biological, and geological system, in perpetual change, under astronomical, predominantly, solar control. It has been shaped to some degree through the past glaciation cycles repeated in the last three million years. The Holocene, the current interglacial epoch which started ca. 11,700 years ago, marks the transition from the Stone Age to the unprecedented cultural evolution of our civilization. Significant climate changes have been recorded in natural archives during the Holocene, including the rapid waning of ice sheets, millennial shifting of the monsoonal fringe in the northern hemisphere, and abrupt centennial events. A typical case of severe environmental change is the greening of Sahara in the Early Holocene and the gradual desertification again since the fifth millennium before present. Climate Changes in the Holocene: Impact, Adaptation, and Resilience investigates the impact of natural climate changes on humans and civilization through case studies from various places, periods, and climates. Earth and human society are approached as a complex system, thereby emphasizing the necessity to improve adaptive capacity in view of the anthropogenic global warming and ecosystem degradation. Features: Written by distinguished experts, the book presents the fundamentals of the climate system, the unparalleled progress achieved in the last decade in the fields of intensified research for improved understanding of the carbon cycle, climate components, and their interaction. Presents the application of paleoclimatology and modeling in climate reconstruction. Examines the new era of satellite-based climate monitoring and the prospects of reduced carbon dioxide emissions.
