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
Modern birds (Neornithes) are represented by two big lineages, the Palaeognathae (Tinamiformes + Ratitae) and the Neognathae [Galloanserae + Neoaves (Metaves + Coronoaves)]. Both clades sum approximately 10,000 species of which 60% are Passeriformes (the most diverse clade of terrestrial vertebrates). A comparison between the past and the present reveals a complex and hallmarked evolutionary and biogeographic history which would have begun over 65 million years ago. For South America (SA) this includes: (1) the presence of taxa with uncertain affinities and the absence of Passeriformes during the Paleogene; (2) a progressive and accelerated increase of the species starting at the Neogene (Miocene); (3) important extinct lineages (e.g. Phorusrhacidae, Teratornithidae) that migrate to North America after the rising of the Panamá isthmus; (4) groups with major diversification in the Neogene that survives nowadays represented by scarce species endemic of SA (Cariamidae) or that inhabits mainly in the southern hemisphere (Anhingidae); (5) very diverse living groups with scarce (e.g., Passeriformes) or none (e.g., Apodiformes) fossil record in SA, which stem-groups are registered in Europe. Apparently, the changes in diversity of the south American Neornithes have been the result of successive radiation, biogeographic connections with North America and in a minor scale, some extinctions. The opening of the Drake ́s passage and the occurrence of the circumpolar Antarctic flow are not sufficient causes to explain the highly disparity between the weddelians penguins (Sphenisciformes) of Antartica and those of the patagonian Atlantic Ocean.

Book Description
Though conflicts continue to arise over land use and land cover changes, the conversion of forest land to cropland or other land uses such as housing and urban development have been on the rise in recent years. Decisions regarding land use and land cover influence climate change as well as various natural processes. While proper changes can minimize the effects and speed of climatic changes, the continued adverse changes may be accelerating the deterioration of the world’s condition. Examining International Land Use Policies, Changes, and Conflicts presents the latest research on the present status of land use and land cover changes throughout the world in order to determine appropriate land use policies that can protect earth’s present and future condition. The findings of the studies investigate the conflicts behind the land tenure and land uses in different countries of the world and examines existing policies and the reasons behind changes in them. Ultimately, the book provides readers with knowledge on how land can be managed in a sustained manner, how landscape models are helpful for predicting and determining future land uses, how land can be managed with the best architectural measures, and how urban forestry is helpful for better environmental management and adapting or mitigating climate change effects. Land users, agriculturalists, urban planners, policymakers, government officials, researchers, academicians, and students looking to improve their understanding of this topic for better use of land in the future will find this book to be an asset to their current research.

Book Description
This volume summarizes the history of Latin American vegetation from just prior to the asteroid impact at Chicxulub, Mexico, at the end of the Cretaceous period through the rapid-paced events of Holocene and Recent times, tracing highlights in the origin of lineages and plant communities that constitute a fundamental part of the tropical ecosystems of the New World. Emphasis is placed on the array of available methods and approaches, as well as on the need for incorporating ancillary information from the many relevant disciplines and for assessing the paleobiological results within the context of independent lines of inquiry--particularly important for understanding the vast and complex communities of Latin America.

Book Description
This book provides an integrated view of Atlantic coastal Patagonian ecosystems, including the physical environment, biodiversity and the main ecological processes, together with their derived ecosystem services and anthropogenic impacts. It focuses on the key components of the aquatic ecosystem, covering the lower levels (plankton) to the top predators like large mammals and birds, before turning to human beings as consumers and shapers of coastal marine resources. The book then presents an overview of how organisms that constitute the aquatic food webs have changed through time and how they likely will soon change due to global change processes and anthropogenic pressures. In this regard it offers a wealth of information such as long-term patterns in physical / atmospheric processes, biodiversity and the distribution of marine organisms, as well as the results of experimental studies designed to understand their responses under future scenarios shaped by both climate change and anthropogenic pressures. The book also covers various aspects of the past, present and potential future relationship of human beings with Patagonian coastal environments, including the utilization of sea products, tourism, and growth of cities.

Book Description
This book focuses on the strong relation between the tectonic evolution of the Southernmost Andes and their closest southern neighbors, the Scotia Sea and Antarctica. Some episodes are related to processes of global significance such as the opening of the Drake Passage, which is somehow linked to Late Cenozoic cooling. Many of the topics covered in the book are subjects of heated debates; as such, not only the latest data and approaches are presented, but different points of view as well. The chapters examine the interrelation between main geodynamic processes and plate tectonics from a multidisciplinary perspective. This Paleozoic-Cenozoic geodynamic evolution of the Southernmost Andes involved interrelated metamorphic, magmatic, sedimentary, and deformational processes directed by plate tectonics. The main topics cover the evolution of the Rocas Verdes basin and the Cordillera Darwin high-grade metamorphic complex, growth of the Patagonian Batholith, development of the Patagonian Orocline, the opening of the Drake Passage during growth of the Scotia Sea, evolution of the Austral-Magallanes foreland basin and its related fold and thrust belt.
