The Arabian Seas: Biodiversity, Environmental Challenges and Conservation Measures
by Laith A. JawadThe Arabian Seas Marine Region encompasses marine areas from Djibouti to Pakistan, including the northern part of Somalia, the Red Sea, the Arabian/Persian Gulf, and parts of the Arabian Sea. Human pressures on the coastal and marine environments are evident throughout the region, and have resulted in harmful environmental effects. Oil and domestic, urban and industrial pollutants in several areas of this part of the world have caused local habitat degradation, eutrophication and algal blooms. Further, coastal landfill, dredging, and sedimentation, as well as nutrient and sediment runoff from phosphate mining, agriculture and grazing, and reduction in freshwater seepage due to groundwater extraction are all contributing to the degradation of coastal environments. This book discusses aspects not covered in other books on the region, which largely focus on marine biodiversity, and examines several environmental challenges that are often ignored, but which have a significant impact on the environment. Evaluating the status quo, it also recommends conservation measures and examines the abiotic factors that play a major main role in the environmental changes. Lastly, the book addresses the biodiversity of the area, providing a general context for the conservation and management measures discussed.

Aralkum - a Man-Made Desert: The Desiccated Floor of the Aral Sea (Central Asia) (Ecological Studies #218)
by Siegmar-W. Breckle Liliya A. Dimeyeva Nathalia P. Ogar Walter WuchererHaving been the fourth largest lake on the globe roughly 50 years ago, today the Aral Sea no longer exists. Human activities caused its desiccation and the formation of a huge new desert, the Aralkum, which can be regarded as one of the greatest ecological catastrophes and - at the same time - the largest primary succession experiment of mankind. This volume brings together the results of international and interdisciplinary long-term studies on the new desert ecosystem and is divided into four main sections. The first section provides an overview of the physical characteristics of the area and covers geological, pedological, geomorphological and climatological aspects and their dynamics, especially dust-storm dynamics. The second focuses on the biotic aspects and highlights the spatial and temporal patterns of the flora and fauna. In the third section studies and projects aiming to combat desertification by phytomelioration and to develop strategies for the conservation of biodiversity are presented. The book is rounded off with a section providing a synthesis and conclusions.

Arbuscular Mycorrhizas and Stress Tolerance of Plants
by Qiang-Sheng WuThis book reviews the potential mechanisms in arbuscular mycorrhizas (AMs), in the hope that this can help arbuscular mycorrhizal fungi (AMF) to be more used efficiently as a biostimulant to enhance stress tolerance in the host plants. AMF, as well as plants, are often exposed to all or many of the abiotic and biotic stresses, including extreme temperatures, pH, drought, water-logging, toxic metals and soil pathogens. Studies have indicated a quick response to these stresses involving several mechanisms, such as root morphological modification, reactive oxygen species change, osmotic adjustment, direct absorption of water by extraradical hyphae, up-regulated expression of relevant stressed genes, glomalin-related soil protein release, etc. The underlying complex, multi-dimensional strategy is involved in morphological, physiological, biochemical, and molecular processes. The AMF responses are often associated with homeostatic regulation of the internal and external environment, and are therefore critical for plant health, survival and restoration in native ecosystems and good soil structure.
Arc-Continent Collision (Frontiers in Earth Sciences)
by Dennis Brown Paul D. RyanArc-continent collision has been one of the important tectonic processes in the formation of mountain belts throughout geological time, and it continues to be so today along tectonically active plate boundaries such as those in the SW Pacific or the Caribbean. Arc-continent collision is thought to have been one of the most important process involved in the growth of the continental crust over geological time, and may also play an important role in its recycling back into the mantle via subduction. Understanding the geological processes that take place during arc-continent collision is therefore of importance for our understanding of how collisional orogens evolve and how the continental crust grows or is destroyed. Furthermore, zones of arc-continent collision are producers of much of the worlds primary economic wealth in the form of minerals, so understanding the processes that take place during these tectonic events is of importance in modeling how this mineral wealth is formed and preserved. This book brings together seventeen papers that are dedicated to the investigation of the tectonic processes that take place during arc-continent collision. It is divided into four sections that deal firstly with the main players involved in any arc-continent collision; the continental margin, the subduction zone, and finally the volcanic arc and its mineral deposits. The second section presents eight examples of arc-continent collisions that range from being currently active through to Palaeoproterozoic in age. The third section contains two papers, one that deals with the obduction of large-slab ophiolites and a second that presents a wide range of physical models of arc-continent collision. The fourth section brings everything that comes before together into a discussion of the processes of arc-continent collision.
Arc Volcano of Japan: Generation of Continental Crust from the Mantle (Lecture Notes in Earth Sciences #136)
by Takeru YanagiThis book presents an analysis of our current knowledge on the origin of the Earth's continental crust. There are two aspects to consider: tectonic and igneous processes. Tectonic aspects include sedimentary accretion, terrane accretion, and continental collision at continental margins, in association with plate subduction. These processes result in the formation of large mountain belts, the building up of which literally grows the continents. However, these tectonic aspects are concerned with material recycling within the crust, and hence do not contribute to volumetric growth of continental crust. Igneous processes concern separation of continental crust from the mantle and result in the volumetric growth of continental crust. Therefore, the main focus of this book is to systematically examine why and how the Earth's continental crust forms, by evaluating magmatic processes at island arcs where new continental crust forms.
Arcadia Updated: Raising landscape awareness through analytical narratives
by Marius Fiskevold Anne Katrine GeelmuydenArcadia Updated delves into the concept of landscape as it is shaped by the literary tradition and material works known as pastoral. Referring to several of the tradition’s works as well as scholarly critiques, Fiskevold and Geelmuyden highlight how individual landscape perception is primarily a cultural construct: each individual may see a unique landscape based on personal experiences, but simultaneously, landscape represents a tradition of engaging with nature and land, which has been largely forgotten. In re-engaging and connecting the practice of understanding landscapes with the pastoral tradition, the authors establish a common ground for treating landscape as an object of analysis in landscape planning. Arcadia Updated contributes to the methodological debate concerning landscape character assessment. Including 30 black-and-white images, this book analyses how humans engage with land organically, materially and communicatively. It seeks to raise landscape awareness as both an individual and a collective act of imagination. The practice of analysing landscapes is an ongoing culture of reinterpreting the land as landscape in response to society’s development and technical progress. The role of the landscape analyst is to interpret the contemporary world and offer visual explanations of it. This book will be beneficial to professional landscape planners as well as to academics and students of landscape, literature and cultural studies. It provides an essential contribution to the cross-disciplinarity of the landscape discourse.

Archaeological Oceanography
by Robert D. BallardArchaeological Oceanography is the definitive book on the newly emerging field of deep-sea archaeology. Marine archaeologists have been finding and excavating underwater shipwrecks since at least the early 1950s, but until recently their explorations have been restricted to depths considered shallow by oceanographic standards. This book describes the latest advances that enable researchers to probe the secrets of the deep ocean, and the vital contributions these advances offer to archaeology and fields like maritime history and anthropology. Renowned oceanographer Robert Ballard--who stunned the world with his discovery of the Titanic deep in the North Atlantic--has gathered together the pioneers of archaeological oceanography, a cross-disciplinary group of archaeologists, oceanographers, ocean engineers, and anthropologists who have undertaken ambitious expeditions into the deep sea. In this book, they discuss the history of archaeological oceanography and the evolution and use of advanced deep-submergence technology to locate and excavate ancient and modern shipwrecks and cultural and other sites deep under water. They offer examples from their own expeditions and explain the challenges future programs face in obtaining access to the resources needed to carry out this important and exciting research. The contributors are Robert D. Ballard, Ali Can, Dwight F. Coleman, Mike J. Durbin, Ryan Eustace, Brendan Foley, Cathy Giangrande, Todd S. Gregory, Rachel L. Horlings, Jonathan Howland, Kevin McBride, James B. Newman, Dennis Piechota, Oscar Pizarro, Christopher Roman, Hanumant Singh, Cheryl Ward, and Sarah Webster.

The Archaeology and Geomorphology of Northern Asia: Selected Works (Arctic Institute of North America Anthropology of the North #No. 5)
by Henry N. MichaelThe eighteen articles appearing in this, the fifth, number of Anthropology of the North: Translations from Russian Sources, were mostly published between the years 1957 and 1963. The exceptions are S.I. Rudenko's "The culture of the prehistoric population of Kamchatka," published in 1948, and A.P. Okladnikov's "Paleolithic remains in the Lena river basin," published in 1953. Thirteen of the articles deal with the archaeology and five with the geomorphology of selected areas of northern Asia. Dr. Chester S. Chard of the University of Wisconsin analyzes the contents and meaning of these articles in his Introduction to the book and fruitfully correlates them with other sources which have been made available to the English-reading specialist over the past few years. In the Notes and References attached to each article, editorial reference has sometimes been added about the availability in English translation of a cited article.
Archaeology from Historical Aerial and Satellite Archives
by Ioana A. Oltean William S. HansonHistorical archives of vertical photographs and satellite images acquired for other purposes (mainly declassified military reconnaissance) offer considerable potential for archaeological and historical landscape research. They provide a unique insight into the character of the landscape as it was over half a century ago, before the destructive impact of later 20th century development and intensive land use. They provide a high quality photographic record not merely of the landscape at that time, but offer the prospect of the better survival of remains reflecting its earlier history, whether manifest as earthworks, cropmarks or soilmarks. These various sources of imagery also provide an opportunity to examine from the air areas of Europe and beyond whose skies are still not open to traditional archaeological aerial reconnaissance. Tens of millions of such images are held in archives around the world, but their research potential goes very largely untapped. A primary aim of this volume is to draw to wider attention the existence, scope and potential access to historical archival aerial and satellite photographs, in order to encourage their use in a range of archaeological and landscape research. By drawing attention to this massive archival resource, providing examples of its successful application to archaeological/landscape questions, and offering advice how to access and utilise the resource, the volume seeks to bring this material to wider attention, demonstrate its huge potential for archaeology, encourage its further use and stimulate a new approach to archaeological survey and the study of landscape evolution internationally.
The Archaeology of Europe’s Drowned Landscapes (Coastal Research Library #35)
by Geoff Bailey Nena Galanidou Hans Peeters Hauke Jöns Moritz MennengaThis open access volume provides for the first time a comprehensive description and scientific evaluation of underwater archaeological finds referring to human occupation of the continental shelf around the coastlines of Europe and the Mediterranean when sea levels were lower than present. These are the largest body of underwater finds worldwide, amounting to over 2500 find spots, ranging from individual stone tools to underwater villages with unique conditions of preservation. The material reviewed here ranges in date from the Lower Palaeolithic period to the Bronze Age and covers 20 countries bordering all the major marine basins from the Atlantic coasts of Ireland and Norway to the Black Sea, and from the western Baltic to the eastern Mediterranean. The finds from each country are presented in their archaeological context, with information on the history of discovery, conditions of preservation and visibility, their relationship to regional changes in sea-level and coastal geomorphology, and the institutional arrangements for their investigation and protection. Editorial introductions summarise the findings from each of the major marine basins. There is also a final section with extensive discussion of the historical background and the legal and regulatory frameworks that inform the management of the underwater cultural heritage and collaboration between offshore industries, archaeologists and government agencies. The volume is based on the work of COST Action TD0902 SPLASHCOS, a multi-disciplinary and multi-national research network supported by the EU-funded COST organisation (European Cooperation in Science and Technology). The primary readership is research and professional archaeologists, marine and Quaternary scientists, cultural-heritage managers, commercial and governmental organisations, policy makers, and all those with an interest in the sea floor of the continental shelf and the human impact of changes in climate, sea-level and coastal geomorphology.
The Archaeology of Human-Environment Interactions: Strategies for Investigating Anthropogenic Landscapes, Dynamic Environments, and Climate Change in the Human Past (Routledge Studies in Archaeology)
by Daniel ContrerasThe impacts of climate change on human societies, and the roles those societies themselves play in altering their environments, appear in headlines more and more as concern over modern global climate change intensifies. Increasingly, archaeologists and paleoenvironmental scientists are looking to evidence from the human past to shed light on the processes which link environmental and cultural change. Establishing clear contemporaneity and correlation, and then moving beyond correlation to causation, remains as much a theoretical task as a methodological one. This book addresses this challenge by exploring new approaches to human-environment dynamics and confronting the key task of constructing arguments that can link the two in concrete and detailed ways. The contributors include researchers working in a wide variety of regions and time periods, including Mesoamerica, Mongolia, East Africa, the Amazon Basin, and the Island Pacific, among others. Using methodological vignettes from their own research, the contributors explore diverse approaches to human-environment dynamics, illustrating the manifold nature of the subject and suggesting a wide variety of strategies for approaching it. This book will be of interest to researchers and scholars in Archaeology, Paleoenvironmental Science, Ecology, and Geology.
Archaeology of Piedra Museo Locality: An Open Window to the Early Population of Patagonia (The Latin American Studies Book Series)
by Laura Miotti Monica Salemme Darío HermoThis book highlights the knowledge about landscapes and characteristics of the earliest hunter-gatherer lifeway in Southern Patagonia. It presents an analysis of the archaeological investigations carried out during three decades by an interdisciplinary team that involved archaeologists, anthropologists, paleontologists, geologists and specialists in pollen and diatoms. The database yielded was recovered from systematic survey and excavations from the Pleistocene and Holocene stratigraphic layers of the rockshelter known as AEP-1, Piedra Museo Locality, situated in the central plateau of Santa Cruz Province, Argentina. Piedra Museo is a unique place in the world of high academic interest with some of the earliest archaeological remains in the Americas. Researchers defined two strata and several Stratigraphic units in the site based on the sedimentological and pedological characteristics. The depositional zones contain archaeological remains that are interpreted as hunting events corresponding to two main different occasions in the human colonization of the region, and a third human occupation during the Middle Holocene. Last one occurred then of the massive rockshelter roof colapse. The faunal remains led to a new approach to the palaeoenvironmental evolution of this enclosed basin. This volume describes the management of lithic raw materials and social networks from first human occupation of the Patagonian region to territorial consolidation of hunter-gatherer societies.
Archaeometallurgy – Materials Science Aspects (Natural Science in Archaeology)
by Andreas HauptmannThis book successfully connects archaeology and archaeometallurgy with geoscience and metallurgy. It addresses topics concerning ore deposits, archaeological field evidence of early metal production, and basic chemical-physical principles, as well as experimental ethnographic works on a low handicraft base and artisanal metal production to help readers better understand what happened in antiquity. The book is chiefly intended for scholars and students engaged in interdisciplinary work.
Archaeoseismology: Methodologies and Case Studies (Natural Science in Archaeology)
by Laura PecchioliArchaeoseismic research provides data and information on past earthquakes but is limited by the lack of ongoing discussions about methodology. This volume is an interdisciplinary approach including archaeologists, geologists, geophysicists, seismologists, engineers, and architects from different countries to present a comprehensive recording and interpretation of ancient natural disasters on some case studies. The publication is an introduction to various aspects of the field of archaeoseismology for the knowledge of past seismicity, the reconstruction of the chronological history of a place, the interpretation and identification of seismic effects using different methods, etc. The collection provides an overview of research into archaeoseismology, making new contributions through innovative ideas on various topics. The publication can be an illustrative introduction to better understand the complexity of interpreting seismic effects on ancient and modern masonries, particularly for students with an open mind.
Archean Evolution of the Pilbara Craton and Fortescue Basin (Modern Approaches in Solid Earth Sciences #24)
by Arthur H. HickmanOne of today’s major geoscientific controversies centres on the origin of the Archean granite‒greenstone terranes. Is the geology of these scattered remnants of our planet’s early crust consistent with the theory that modern-style plate-tectonic processes operated from the early Archean, or does it indicate that tectonic and magmatic processes were different in the Archean? Earth has clearly evolved since its initial formation, so at what stage did its processes of crustal growth first resemble those of today? The logical place to seek answers to these intriguing and important questions is within the best-preserved early Archean crust. The Pilbara region of northwest Australia is internationally famous for its abundant and exceptionally well-preserved fossil evidence of early life. However, until recently the area has received much less recognition for the key evidence it provides on early Archean crustal evolution. This book presents and interprets this evidence through a new stage-by-stage account of the development of the Pilbara’s geological record between 3.53 and 2.63 Ga. The Archean Pilbara crust represents one fragment of Earth’s oldest known supercontinent Vaalbara, which also included the Kaapvaal Craton of southern Africa. Recognition of Vaalbara expands the background database for both these areas, allowing us to more fully understand each of them.
Archean-Mesoproterozoic Crustal Evolution and Crust-Mantle Geodynamics of Western Liaoning-Northeastern Hebei Provinces, North China Craton (Springer Theses)
by Wei WangThis thesis presents geological, petrological, geochemical, and zircon U-Pb-Lu-Hf isotopic field data for representative Precambrian lithologies in the Western Liaoning-Northeastern Hebei Provinces along the northern margin of the North China Craton (NCC). It describes late Neoarchean (2. 64-2. 48 Ga) supracrustal metavolcanic rocks and granitoid gneisses; late Paleoproterozoic (1. 72-1. 68 Ga) Jianping alkaline plutons and Pinggu alkaline volcanic rocks; and newly discovered ~1. 23 Ga mafic dykes. The nature of magma sources and genesis of each magmatic episode are investigated, and the Precambrian (~2. 6-1. 2 Ga) lithospheric mantle evolution and crust-mantle interaction processes are established for the first time -aspects that provide important constraints in our understanding of the Precambrian crustal evolution and geodynamic processes in the region studied.
Archean Rare-Metal Pegmatites in Zimbabwe and Western Australia: Geology and Metallogeny of Pollucite Mineralisations (SpringerBriefs in World Mineral Deposits)
by Thomas Dittrich Thomas Seifert Bernhard Schulz Steffen Hagemann Axel Gerdes Jörg PfänderLithium-cesium-tantalum (LCT) pegmatites are important resources for rare metals. For Cs, only the LCT pegmatites with the zeolite group mineral pollucite at Bikita (Zimbabwe Craton) and Tanco (Superior Province Craton) are of commercial importance. Common characteristics of world-class LCT pegmatite deposits include their Meso- to Neoarchean age and geological setting within greenstone belt lithologies on Archean Cratons.This study presents the first coherent and comparative scientific investigation of five major LCT pegmatite systems from the Yilgarn, Pilbara and Zimbabwe Craton. For the evaluation of their Cs potential and of the genetic concepts of pollucite formation, the pegmatites from Wodgina, Londonderry, Mount Deans and Cattlin Creek were compared to the Bikita pollucite mineralization. The integration of the new data (e.g., geochronological and radiogenic isotope data) into the complex geological framework: 1) enhances our knowledge of the formation of LCT pegmatite systems, and 2) will contribute to the further exploration of additional world-class LCT pegmatite deposits, which 3) may host massive pollucite mineralisations.
