Advances in Coastal Geoarchaeology in Latin America


Book Description

This book introduces selected contributions from the GEGAL (Spanish acronym for Latin American Geoarchaeological Studies Group) Workshop held at La Paloma Beach, Uruguay, with a focus on Coastal Geoarchaeology, and an attendance of more than 50 researchers, students and professionals from several Latin American countries. The contributions were selected in order to encompass the vast array of environmental, geomorphological and archaeological contexts comprised in the geographical frame of Latin America. Topics covered through the chapters include specific issues such as human occupation and fluvial dynamic processes in mountain and lowland environments, methodological developments in dating methods, taphonomy and chemical proxies, as well as landscape modification by anthropogenic disturbances. As the first compilation of Coastal Geoarchaeology for Latin America, this book is intended to become a useful tool for students, researchers and professionals from related fields, as it comprises not only the regional state of the art, but also new insights and developments which can be potentially applied to other contexts world wide.




Actualistic Taphonomy in South America


Book Description

Highlighting the latest research on Actualistic Taphonomy (AT), this book presents the outcomes of a meeting that took place in Montevideo, Uruguay, in October 2017. Its respective chapters offer valuable insights into South American archaeology, invertebrate and vertebrate fauna, and flora. In recent years, there has been a surge of new research on AT, as evidenced by numerous papers, talks, theses, etc. However, there are still very few AT books or even dedicated journal articles. Reflecting the discipline’s newfound maturity, this book, written by South American authors, offers a unique resource for academics and students of Paleontology, Geology, and Biology around the world.




Genetics, Evolution, and Conservation of Neotropical Fishes


Book Description

Fish represent the most ancestral and specious group of vertebrates, and occupy more diverse aquatic environments around the world. Ichthyofauna is extremely diverse, especially in megadiverse countries occupying biogeographical regions such as the Neotropical Region, which covers an extensive area between North and South America. Much of this biodiversity will be extinct, even before science knows any aspect of its biology. Like this, Neotropical fish genetics started in the end of the 70’s with papers studying the chromosomes of Hoplias malabaricus (Family Erythrinidae) and the karyotype variation among three genera of the family Anostomidae. The topic at that time was concentrated in two Institutions from the state of São Paulo, Southeastern Brazil. In the middle 80’s, the first Symposium on Neotropical Fish Cytogenetics was organized. Nowadays, the field of Neotropical Fish Genetics is present in Brazil, Colombia, Argentina, Uruguai, Venezula, Chile, and Equador, as well as outside South America in Panama, Mexico, USA, Canada, Czech Republic, Germany, and Spain. The research developed in cytogenetics has focused mainly on karyotype evolution and cytotaxonomy, chromosome structure and, more recently, cytogenomics. In relation to the use of molecular markers, support has been sought for the management of populations for conservation or production in captivity. In addition, many studies have been carried out with the aim of establishing supra-specific phylogenetic relationships and clarifying species distribution scenarios by phylogeographic modeling. The genome and transcriptome of some model species begin to emerge as extremely promising and informative areas for neotropical fish. In 2017, the Neotropical fish genetics research community celebrates the 30th anniversary of its main Meeting (today entitled Symposium on Neotropical Fish Genetics and Cytogenetics). This Research Topic is part of this celebration and aims at reporting the state of the art and its current advances in the frontier of knowledge in genetics, evolution, and conservation of neotropical fish, as well as to detect the challenges to be overcome in the next years.




Historical Perspectives to Postglacial Uplift


Book Description

This Brief discusses a unique mechanism to combine historical and archaeological evidence with statistical geodynamic modeling to study the historical development of the Eura region in lower Satakunta, Finland; this region is known for its rich cultural history. The book presents methods to model postglacial land uplift and the historical landscape. By using coupled data, it is possible to narrow the dating estimates of the archaeologically important places and structures and to build a more detailed reconstruction of landscape evolution in connection with the knowledge about human settlements and their movements. The resulting geospatial and uplift models are included as supplements. The primary audience for this book is experts and professionals working in the fields of archaeology, geography, geology and geospatial data analysis.




Geology and Paleontology of the Quaternary of Uruguay

It is primarily based on an analysis of the geological and paleontological evidences, synthesizing the time (numerical ages, biostratigraphy), environment and climatic situations involved and highlighting the most relevant paleontological content.




Advances in Geomorphology and Quaternary Studies in Argentina


Book Description

These proceedings contain selected papers from the Special Symposium, organised by the Argentine Association of Geomorphology and Quaternary Studies in October 2017. This Symposium was held within the frame of the 20th Argentine Geological Congress in Tucumán, Argentina. The papers describe detailed research on quaternary stratigraphy and geochronology, paleontology (diatoms, mollusks, foraminifera, palynology, phytoliths, paleobotany, vertebrates), dendrochronology, climate change, paleoclimate, pampeano quaternary paleolimnology, paleomagnetism, environmental magnetism, hydrogeochemical processes, geoarchaeology, geomorphology, structural geology and neotectonics, paleosurfaces, volcanism, risks, assets, geomorphosites, and digital mapping. This book follows the precedent book “Advances in Geomorphology and Quaternary Studies in Argentina” on the 6th Argentine Geomorphology and Quaternary Studies Congress, which was edited by Jorge Rabassa and published by Springer in 2017. It precedes a similar volume on the 7th Congreso Argentino de Cuaternario y Geomorfología, “Geocuar 2018”, as organized by Argentine Association of Geomorphology and Quaternary Studies (AACG). This conference was held in Puerto Madryn, Chubut, Argentina, from 18 to 21 September 2018.










Earth's Climate Evolution


Book Description

To understand climate change today, we first need to know how Earth’s climate changed over the past 450 million years. Finding answers depends upon contributions from a wide range of sciences, not just the rock record uncovered by geologists. In Earth’s Climate Evolution, Colin Summerhayes analyzes reports and records of past climate change dating back to the late 18th century to uncover key patterns in the climate system. The book will transform debate and set the agenda for the next generation of thought about future climate change. The book takes a unique approach to the subject providing a description of the greenhouse and icehouse worlds of the past 450 million years since land plants emerged, ignoring major earlier glaciations like that of Snowball Earth, which occurred around 600 million years ago in a world free of land plants. It describes the evolution of thinking in palaeoclimatology and introduces the main players in the field and how their ideas were received and, in many cases, subsequently modified. It records the arguments and discussions about the merits of different ideas along the way. It also includes several notes made from the author’s own personal involvement in palaeoclimatological and palaeoceanographic studies, and from his experience of working alongside several of the major players in these fields in recent years. This book will be an invaluable reference for both undergraduate and postgraduate students taking courses in related fields and will also be of interest to historians of science and/or geology, climatology and oceanography. It should also be of interest to the wider scientific and engineering community, high school science students, policy makers, and environmental NGOs. Reviews: "Outstanding in its presentation of the facts and a good read in the way that it intersperses the climate story with the author's own experiences. [This book] puts the climate story into a compelling geological history." -Dr. James Baker "The book is written in very clear and concise prose, [and takes] original, enlightening, and engaging approach to talking about 'ideas' from the perspective of the scientists who promoted them." -Professor Christopher R. Scotese "A thrilling ride through continental drift and its consequences." - Professor Gerald R. North "Written in a style and language which can be easily understood by laymen as well as scientists." - Professor Dr Jörn Thiede "What makes this book particularly distinctive is how well it builds in the narrative of change in ideas over time." - Holocene book reviews, May 2016 "This is a fascinating book and the author’s biographical approach gives it great human appeal." - E Adlard
