Download or read book Gene Drives on the Horizon written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2016-08-28 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research on gene drive systems is rapidly advancing. Many proposed applications of gene drive research aim to solve environmental and public health challenges, including the reduction of poverty and the burden of vector-borne diseases, such as malaria and dengue, which disproportionately impact low and middle income countries. However, due to their intrinsic qualities of rapid spread and irreversibility, gene drive systems raise many questions with respect to their safety relative to public and environmental health. Because gene drive systems are designed to alter the environments we share in ways that will be hard to anticipate and impossible to completely roll back, questions about the ethics surrounding use of this research are complex and will require very careful exploration. Gene Drives on the Horizon outlines the state of knowledge relative to the science, ethics, public engagement, and risk assessment as they pertain to research directions of gene drive systems and governance of the research process. This report offers principles for responsible practices of gene drive research and related applications for use by investigators, their institutions, the research funders, and regulators.
Download or read book Surface Temperature Reconstructions for the Last 2 000 Years written by National Research Council and published by National Academies Press. This book was released on 2007-01-05 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: In response to a request from Congress, Surface Temperature Reconstructions for the Last 2,000 Years assesses the state of scientific efforts to reconstruct surface temperature records for Earth during approximately the last 2,000 years and the implications of these efforts for our understanding of global climate change. Because widespread, reliable temperature records are available only for the last 150 years, scientists estimate temperatures in the more distant past by analyzing "proxy evidence," which includes tree rings, corals, ocean and lake sediments, cave deposits, ice cores, boreholes, and glaciers. Starting in the late 1990s, scientists began using sophisticated methods to combine proxy evidence from many different locations in an effort to estimate surface temperature changes during the last few hundred to few thousand years. This book is an important resource in helping to understand the intricacies of global climate change.

Download or read book Manual of the Vascular Flora of the Carolinas written by Albert E. Radford and published by Univ of North Carolina Press. This book was released on 2010-06-15 with total page 1246 pages. Available in PDF, EPUB and Kindle. Book excerpt: This illustrated manual describes and discusses the unusually rich and varied flora of the Carolinas, from the semi-tropical coast of South Carolina to the northern forests of the high North Carolina mountains. The manual treats in detail and in a concise format more than 3, 200 species of trees, shrubs, vines, herbs and ferns that grow without cultivation in this two-state area. Special features include diagnostic illustrations, keys for identification, detailed descriptions, flowering and fruiting dates, habitat data, distribution data, and pertinent synonymy for each species. County dot maps show the distribution of each species if found in more than five counties throughout the two-state area, and general ranges beyond our borders are given in the text. First published in 1968, Manual of the Vascular Flora of the Carolinas is an established reference for professionals, students, and plant enthusiasts throughout the Southeastern United States. It is based on the collection and examination of more than 200,000 live specimens. Many of these specimens are now housed in the herbarium at the University of North Carolina at Chapel Hill

Download or read book Forgotten Grasslands of the South written by Reed F. Noss and published by Island Press. This book was released on 2012-12-03 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forgotten Grasslands of the South is the study of one of the biologically richest and most endangered ecosystems in North America. In a seamless blend of science and personal observation, renowned ecologist Reed Noss explains the natural history of southern grasslands, their origin and history, and the physical determinants of grassland distribution, including ecology, soils, landform, and hydrology. In addition to offering fascinating new information about these little-studied ecosystems, Noss demonstrates how natural history is central to the practice of conservation. Although theory and experimentation have recently dominated the field of ecology, ecologists are coming to realize how these distinct approaches are not divergent but complementary, and that pursuing them together can bring greater knowledge and understanding of how the natural world works and how we can best conserve it. This long-awaited work sets a new standard for scientific literature and is essential reading for those who study and work to conserve the grasslands of the South as well as for everyone who is fascinated by the natural world.
