Book Description
This book presents a novel approach in the field of global change by presenting a comprehensive analysis of interhemispheric linkages of climate, present and past, and their effects on human societies. The ultimate goal of this interhemispheric integration is to improve our understanding of causes and mechanisms of climate change to enhance our capability in predicting future changes. Given the societal interest in global change issues this book offers a new approach for the integration of global information. It will provide a reference for professional scientists, researchers and graduate students in the fields of climatology, and the earth and environmental sciences. - Chapters analyse instrumental atmospheric and oceanic data to address such phenomena as El Nino/Southern Oscillation variability and other climate anomalies such as the Pacific and North Atlantic Oscillation and polar air outbreaks - A new systematic methodology is presented that allows objective and verifiable reconstruction of climate fields from sparse data - Especially valuable in the context of climate proxy data

Book Description
This concise and accessible new text offers original and insightful analysis of the policy paradigm informing international statebuilding interventions. The book covers the theoretical frameworks and practices of international statebuilding, the debates they have triggered, and the way that international statebuilding has developed in the post-Cold War era. Spanning a broad remit of policy practices from post-conflict peacebuilding to sustainable development and EU enlargement, Chandler draws out how these policies have been cohered around the problematization of autonomy or self-government. Rather than promoting democracy on the basis of the universal capacity of people for self-rule, international statebuilding assumes that people lack capacity to make their own judgements safely and therefore that democracy requires external intervention and the building of civil society and state institutional capacity. Chandler argues that this policy framework inverses traditional liberal “democratic understandings of autonomy and freedom “ privileging governance over government “ and that the dominance of this policy perspective is a cause of concern for those who live in states involved in statebuilding as much as for those who are subject to these new regulatory frameworks. Encouraging readers to reflect upon the changing understanding of both state “society relations and of the international sphere itself, this work will be of great interest to all scholars of international relations, international security and development.

Book Description
The Southern Andes, stretching from the subtropics to the subantarctic, are ideally located for palaeoenvironmental research. Over the broad and continuous latitudinal extent of the cordillera (-24˚), vegetation is adjusted to climatic gradients and atmospheric circulation patterns.Opposed to the prevailing Southern Westerlies, the Southern Andes are positioned to receive the brunt of the winds, while biota are set to record the shifting of incoming storm systems over time. Sequential, latitudinally-placed, sedimentary deposits containing microfossils and macroremains, as archives of past vegetation and climate, make possible the detection of equatorward and poleward displacement of plant communities and, as a consequence, changes in climatic controls. No terrestrial setting in the Southern Hemisphere is so unique for palaeoenvironmental reconstruction during and since the last ice age. Twenty radiocarbon-dated fossil pollen and spore records chosen to place emphasis on the last ice age include high-resolution, submillennial data sets that also cover the Holocene, thus providing contrast between present interglacial and past glacial ages. From a refined data base, the records constitute the foundation for interpreting factors responsible for vegetation change over >50,000 14C years, glacial-interglacial migration and refugial patterns for a diversity of taxa, and the extent of intrahemispheric and polar hemispheric synchroneity versus asynchroneity.

Book Description
Written by highly qualified Argentine scientists and scholars, this book focuses on the uninterrupted geological and paleontological record of Patagonia and Tierra del Fuego since the Miocene-Pliocene boundary to the arrival of man and modern times. This region is an outstanding area for research, with significant interest at the international level. It provides an updated overview of the scientific work in all related fields with a strong paleoclimatic approach. Patagonia has also been a sort of a "paleoclimatic bridge" between the Antarctic Peninsula and the more northerly land masses, since the final opening of the Drake Passage in the middle Miocene. Timely and comprehensive, The Late Cenozoic of Patagonia and Tierra del Fuego is the only monograph book written in English.* One-stop resource for paleontological information of the Late Cenozoic of Patagonia* Covers 5 million years in the uninterrupted history of Patagonia and Tierra del Fuego* Comprehensive coverage of the region written by highly qualified Argentine scientists and scholars

Book Description
The changing focus and approach of geomorphic research suggests that the time is opportune for a summary of the state of discipline. The number of peer-reviewed papers published in geomorphic journals has grown steadily for more than two decades and, more importantly, the diversity of authors with respect to geographic location and disciplinary background (geography, geology, ecology, civil engineering, computer science, geographic information science, and others) has expanded dramatically. As more good minds are drawn to geomorphology, and the breadth of the peer-reviewed literature grows, an effective summary of contemporary geomorphic knowledge becomes increasingly difficult. The fourteen volumes of this Treatise on Geomorphology will provide an important reference for users from undergraduate students looking for term paper topics, to graduate students starting a literature review for their thesis work, and professionals seeking a concise summary of a particular topic. Information on the historical development of diverse topics within geomorphology provides context for ongoing research; discussion of research strategies, equipment, and field methods, laboratory experiments, and numerical simulations reflect the multiple approaches to understanding Earth’s surfaces; and summaries of outstanding research questions highlight future challenges and suggest productive new avenues for research. Our future ability to adapt to geomorphic changes in the critical zone very much hinges upon how well landform scientists comprehend the dynamics of Earth’s diverse surfaces. This Treatise on Geomorphology provides a useful synthesis of the state of the discipline, as well as highlighting productive research directions, that Educators and students/researchers will find useful. Geomorphology has advanced greatly in the last 10 years to become a very interdisciplinary field. Undergraduate students looking for term paper topics, to graduate students starting a literature review for their thesis work, and professionals seeking a concise summary of a particular topic will find the answers they need in this broad reference work which has been designed and written to accommodate their diverse backgrounds and levels of understanding Editor-in-Chief, Prof. J. F. Shroder of the University of Nebraska at Omaha, is past president of the QG&G section of the Geological Society of America and present Trustee of the GSA Foundation, while being well respected in the geomorphology research community and having won numerous awards in the field. A host of noted international geomorphologists have contributed state-of-the-art chapters to the work. Readers can be guaranteed that every chapter in this extensive work has been critically reviewed for consistency and accuracy by the World expert Volume Editors and by the Editor-in-Chief himself No other reference work exists in the area of Geomorphology that offers the breadth and depth of information contained in this 14-volume masterpiece. From the foundations and history of geomorphology through to geomorphological innovations and computer modelling, and the past and future states of landform science, no "stone" has been left unturned!

Book Description
Urumaco and Venezuelan Paleontology offers a synthesis of the paleontological record of Venezuela, including new discoveries on stratigraphy, paleobotany, fossil invertebrates, and vertebrates. Besides providing a critical summary of the record of decapods, fishes, crocodiles, turtles, rodents, armadillos, and ungulates, several chapters introduce new information on the distribution and paleobiology of groups not previously studied in this part of the world. Given its position in the northern neotropics, close to the Panamanian land bridge, Venezuela is a key location for understanding faunal exchanges between the Americas in the recent geological past. The book reviews the recent paleobotanical and vertebrate fossil record of the region, provides an understanding of Pleistocene climatic change and biogeography for the last few thousand years, and integrates new information with summaries of Spanish language works on Venezuelan geology and paleontology.

Book Description
One of the most intriguing paleobiogeographical phenomena involving the origins and gradual sundering of Gondwana concerns the close similarities and, in most cases, inferred sister-group relationships of a number of terrestrial and freshwater vertebrate taxa, e.g., dinosaurs, flying birds, mammals, etc., recovered from uppermost Cretaceous/ Paleogene deposits of West Antarctica, South America, and NewZealand/Australia. For some twenty five extensive and productive investigations in the field of vertebrate paleontology has been carried out in latest Cretaceous and Paleogene deposits in the James Ross Basin, northeast of the Antarctic Peninsula (AP), West Antarctica, on the exposed sequences on James Ross, Vega, Seymour (=Marambio) and Snow Hill islands respectively. The available geological, geophysical and marine faunistic evidence indicates that the peninsular (AP) part of West Antarctica and the western part of the tip of South America (Magallanic Region, southern Chile) were positioned very close in the latest Cretaceous and early Paleogene favoring the “Overlapping” model of South America-Antarctic Peninsula paleogeographic reconstruction. Late Cretaceous deposits from Vega, James Ross, Seymour and Snow Hill islands have produced a discrete number of dinosaur taxa and a number of advanced birds together with four mosasaur and three plesiosaur taxa, and a few shark and teleostean taxa.
