Fossil Horses of South America

by José Luis Prado María Teresa Alberdi

This book provides an update on the phylogeny, systematics and ecology of horses in South America based on data provided over the past three decades. The contemporary South American mammalian communities were shaped by the emergence of the Isthmus of Panama and by the profound climatic oscillations during the Pleistocene. Horses were a conspicuous group of immigrant mammals from North America that arrived in South America during the Pleistocene. This group is represented by 2 genera, Hippidion and Equus, which include small species (Hippidion devillei, H. saldiasi, E. andium and E. insulatus) and large forms (Equus neogeus and H. principale). Both groups arrived in South America via 2 different routes. One model designed to explain this migration indicates that the small forms used the Andes corridor, while larger horses used the eastern route and arrived through some coastal areas. Molecular dating (ancient DNA) suggests that the South American horses separated from the North American taxa (caballines and the New World stilt-legged horse) after 3.6 - 3.2 Ma, consistent with the final formation of the Panamanian Isthmus. Recent studies of stable isotopes in these horses indicate an extensive range of 13C values cover closed woodlands to C4 grasslands. This plasticity agrees with the hypothesis that generalist species and open biome specialist species from North America indicate a positive migration through South America.

Fossil Fuel Hydrogen: Technical, Economic and Environmental Potential

by William J. Nuttall Adetokunboh T. Bakenne

As the case for Climate Change mitigation becomes ever more pressing, hydrogen has the potential to play a major role in a low-carbon energy future. Hydrogen can drive the vehicles of tomorrow and also heat homes and supply energy to businesses. Much recent discussion in energy policy circles has considered ways in which greatly expanded electrification can meet the demand for low-carbon mobility and heating. Such narratives centre on the widespread use of renewable energy sources with occasionally surplus renewable electricity being used to produce hydrogen, for example by electrolysis. While such developments have a beneficial role to play, this book focuses on an alternative paradigm. This book considers a more evolutionary path involving the continued extraction and use of fossil fuels, most notably natural gas, but in ways that greatly reduce greenhouse gas emissions. In this way much established industrial capacity and know how might be transitioned to help deliver the low carbon future that the world so desperately requires. Presenting up-to-date energy policy recommendations with a focus on hydrogen from fossil fuels, the book will be of considerable interest to policymakers and energy researchers in academia, industry and government labs, while also offering a valuable reference guide for business developers in low-carbon energy, and for oil and gas industry analysts.

Forward-Time Population Genetics Simulations

by Bo Peng Marek Kimmel Christopher I. Amos

The only book available in the area of forward-time population genetics simulations--applicable to both biomedical and evolutionary studies The rapid increase of the power of personal computers has led to the use of serious forward-time simulation programs in genetic studies. Forward-Time Population Genetics Simulations presents both new and commonly used methods, and introduces simuPOP, a powerful and flexible new program that can be used to simulate arbitrary evolutionary processes with unique features like customized chromosome types, arbitrary nonrandom mating schemes, virtual subpopulations, information fields, and Python operators. The book begins with an overview of important concepts and models, then goes on to show how simuPOP can simulate a number of standard population genetics models--with the goal of demonstrating the impact of genetic factors such as mutation, selection, and recombination on standard Wright-Fisher models. The rest of the book is devoted to applications of forward-time simulations in various research topics. Forward-Time Population Genetics Simulations includes: An overview of currently available forward-time simulation methods, their advantages, and shortcomings An overview and evaluation of currently available software A simuPOP tutorial Applications in population genetics Applications in genetic epidemiology, statistical genetics, and mapping complex human diseases The only book of its kind in the field today, Forward-Time Population Genetics Simulations will appeal to researchers and students of population and statistical genetics.

Fortuna: A Felix Taylor Adventure

by Nicholas Maes

Felix Taylor once stopped a devastating plague, but now he must save his world from humankind itself. It’s been a year since Felix Taylor travelled back to ancient Rome and saved his world from a lethal plague. Again his knowledge of Latin seems useless now that life in the 23rd century has returned to normal. But is it really?A stranger has discovered the time machine and used it to project back into the past. It becomes clear his purpose is to reverse Felix’s success, to bring back the plague and doom future generations to death. To make matters worse, this stranger is very close to Felix.With help from his friend Carolyn, Felix must return to the world of Julius Caesar, as well as a later era divided by religion, to stop the re-emergence of the plague. If he fails to do so, his world will turn to dust like ancient Rome.

From the earliest colonial settlements to Cold War bunkers, the North American continent has been home to thousands of forts and fortress structures. Fortress America surveys the broad sweep of fortifications throughout North America-from seacoast forts of the late eighteenth century to wooden inland forts built to defend against Native American, English,French, or Spanish attack; from Civil War-era coastal and inland waterways forts to the Great Plains' forts of the Old West; from World War II subterranean bunkers to Cold Warconcrete missile silos. The text of Fortress America is complemented with never-before-published photographs, and extraordinary drawings, cut-aways, and diagrams illustrating the design and structure of American forts.

Fortifying China: The Struggle to Build a Modern Defense Economy

by Tai Ming Cheung

Fortifying China explores the titanic struggle to turn China into an aspiring world-class military technological power. The defense economy is leveraging the country's vibrant civilian economy and gaining access to foreign sources of technology and know-how. Drawing on extensive Chinese-language sources, Tai Ming Cheung explains that this transformation has two key dimensions. The defense economy is being reengineered to break down bureaucratic barriers and reduce the role of the state, fostering a more competitive and entrepreneurial culture to facilitate the rapid diffusion and absorption of technology and knowledge. At the same time, the civilian and defense economies are being integrated to form a dual-use technological and industrial base.In Cheung's view, the Chinese authorities believe this strategy will play a key role in supporting long-term defense modernization. For China's neighbors and the United States, understanding China's technological, industrial, and military capabilities is critical to the formulation of economic and security policies. Fortifying China provides crucial insight into the impact of China's dual-use technology strategy. Cheung's "systems of innovation" framework considers the structure, dynamics, and performance of the defense economy from a systems-level perspective.

by Hans Rudolf Heinimann Alfred Teischinger

Das vorliegende Buch bietet eine Auslegeordnung, wie sich die Forst- und Holzwirtschaft Mitteleuropas orientieren kann, um die Nachhaltigkeits- und Klimawende mitzugestalten und zu einer Bioökonomie und Kreislaufwirtschaft beizutragen. Die Leitidee des Buches ist es, Optionen darzustellen und dies in der Absicht, die Vielfalt des Denkens und Handelns zu inspirieren. Vielfalt ist eine Voraussetzung, um mit unsicheren und unerwarteten Ereignissen, mit denen wir vermehrt konfrontiert sein werden, umgehen zu können. Das Buch analysiert, was die Leitbilder und Konzepte, welche den Nachhaltigkeits-, den Klima- sowie den sozialen Wandel prägen, für den Forst- und Holzsektor bedeuten. Es stellt danach die Hindernisse, welche die angestrebten Wenden behindern, und die „objektiven Realitäten“ dar, von denen eine Anpassung des Forst- und Holzsektors ausgehen muss. Die Pfade einer zukunftsfähigen Entwicklung beschreiben das wald- und holzspezifische Management des Kohlenstoffkreislaufes, die Weiterentwicklung des sozialen, institutionellen Arrangements, die Weiterentwicklung der Waldbausysteme sowie die Zukunft der stofflichen und energetischen Nutzung von Holz. Das Spektrum bisheriger Beiträge zum aktuellen Wandel sowie zu den Erwartungen und Anforderungen an Lösungen ist sehr breit und verkörpert die jeweils sehr spezifische Sichtweise einzelner Interessensgruppen. Dieses Buch ist ein Beitrag, Licht in das objektive Ödland, das in den letzten Jahren entstanden ist, zu werfen, und neben der Biodiversität in Wald und Natur auch die Diversität der Ideen zur erfolgreichen Bewältigung des Wandels zu stimulieren.
