The Trace-Fossil Record of Major Evolutionary Events

by M. Gabriela Mángano Luis A. Buatois

This volume addresses major evolutionary changes that took place during the Mesozoic and the Cenozoic. These include discussions on major evolutionary radiations and ecological innovations on land and at sea, such as the Mesozoic marine revolution, the Mesozoic radiation of vertebrates, the Mesozoic lacustrine revolution, the Cenozoic radiation of mammals, the evolution of paleosol biotas, and the evolution of hominins. The roles of mass extinctions at the end of the Triassic and at the end of the Cretaceous are assessed. This volume set provides innovative reviews of the major evolutionary events in the history of life from an ichnologic perspective. Because the long temporal range of trace fossils has been commonly emphasized, biogenic structures have been traditionally overlooked in macroevolution. However, comparisons of ichnofaunas through geologic time do reveal the changing ecology of organism-substrate interactions. The use of trace fossils in evolutionary paleoecology represents a new trend that is opening a window for our understanding of major evolutionary radiations and mass extinctions. Trace fossils provide crucial evidence for the recognition of spatial and temporal patterns and processes associated with paleoecologic breakthroughs.

The Trace-Fossil Record of Major Evolutionary Events

by M. Gabriela Mángano Luis A. Buatois

This volume addresses major evolutionary changes that took place during the Ediacaran and the Paleozoic. These include discussions on the nature of Ediacaran ecosystems, as well as the ichnologic signature of evolutionary radiations, such as the Cambrian explosion and the Great Ordovician biodiversification event, the invasion of the land, and the end-Permian mass extinction.

Trace Metals and Fluoride in Bones and Teeth

by Nicholas D. Priest Frank Van de Vyver

This volume is a comprehensive introduction to the analysis, binding, uptake, metabolism, kinetics, modeling, distribution, occurrence, toxicity and chelation of metals and fluoride in the body, with special reference to mineralized tissues. Both toxic and relatively harmless polyvalent cations and anions are considered. Included are some which are stable, and others which are radioactive. While a number are essential trace elements, others have no known metabolic role. Most chapters are concerned with the uptake of bone-seeking ions by the living skeleton, but aspects of the post-mortem uptake of metals and the process of fossilization are also considered. Highlighted are the utility of modern analytical techniques and the more important bone-seeking elements including aluminum, lead, cadmium, fluorine and the radioactive heavy metals including uranium and plutonium. This important publication is of particular value to those in the fields of biochemistry, radioactive waste, geology, physiology, dentistry, orthopedics, radiology and nuclear medicine, urology, industrial hygiene, pharmacology, anthropology, paleontology, and archeology.

Trace Metals in Aquatic Systems

by Robert P. Mason

This book provides a detailed examination of the concentration, form and cycling of trace metals and metalloids through the aquatic biosphere, and has sections dealing with the atmosphere, the ocean, lakes and rivers. It discusses exchanges at the water interface (air/water and sediment/water) and the major drivers of the cycling, concentration and form of trace metals in aquatic systems. The initial chapters focus on the fundamental principles and modelling approaches needed to understand metal concentration, speciation and fate in the aquatic environment, while the later chapters focus on specific environments, with case studies and research highlights. Specific examples deal with metals that are of particular scientific interest, such as mercury, iron, arsenic and zinc, and the book deals with both pollutant and required (nutrient) metals and metalloids. The underlying chemical principles controlling toxicity and bioavailability of these elements to microorganisms and to the aquatic food chain are also discussed. Readership: Graduate students studying environmental chemistry and related topics, as well as scientists and managers interested in the cycling of trace substances in aqueous systems Additional resources for this book can be found at: www.wiley.com/go/mason/tracemetals.

Trace Your Roots with DNA: Using Genetic Tests to Explore Your Family Tree

by Ann Turner Megan Smolenyak Smolenyak

Written by two of the country's top genealogists, Trace Your Roots with DNA is the first book to explain how new and groundbreaking genetic testing can help you research your ancestryAccording to American Demographics, 113 million Americans have begun to trace their roots, making genealogy the second most popular hobby in the country (after gardening). Enthusiasts clamor for new information from dozens of subscription-based websites, email newsletters, and magazines devoted to the subject. For these eager roots-seekers looking to take their searches to the next level, DNA testing is the answer. After a brief introduction to genealogy and genetics fundamentals, the authors explain the types of available testing, what kind of information the tests can provide, how to interpret the results, and how the tests work (it doesn't involve digging up your dead relatives). It's in expensive, easy to do, and the results are accurate: It's as simple as swabbing the inside of your cheek and popping a sample in the mail. Family lore has it that a branch of our family emigrated to Argentina and now I've found some people there with our name. Can testing tell us whether we're from the same family?My mother was adopted and doesn't know her ethnicity. Are there any tests available to help her learn about her heritage? I just discovered someone else with my highly unusual surname. How can we find out if we have a common ancestor? These are just a few of the types of genealogical scenarios readers can pursue. The authors reveal exactly what is possible-and what is not possible-with genetic testing. They include case studies of both famous historial mysteries and examples of ordinary folks whose exploration of genetic genealogy has enabled them to trace their roots.

Traced: Human DNA's Big Surprise

by Nathaniel Jeanson

What happened to the ancient Egyptians? The Persians? The Romans? The Mayans? ARE WE THEIR DESCENDANTS? Recent genetic discoveries are uncovering surprising links between us and the peoples of old—links that rewrite race, ethnicity, and human history. Today’s Native Americans descend from Central Asians who arrived in the early A.D. era. Abraham, Isaac, and Jacob still have clearly identifiable descendants, albeit rare ones. Every people group on earth can genetically trace their origins to Noah and his three sons.

They address a number of topics in hydrology tracing techniques including: protection of natural resources against pollution; the use of natural and artificial tracers to help to assess contaminant transport in surface waters; and aquifer parameters and modelling.

Tracer Technology

by Octave Levenspiel

The tracer method was first introduced to measure the actual flow of fluid in a vessel, and then to develop a suitable model to represent this flow. Such models are used to follow the flow of fluid in chemical reactors and other process units, in rivers and streams, and through soils and porous structures. Also, in medicine they are used to study the flow of chemicals, harmful or not, in the blood streams of animals and man. Tracer Technology, written by Octave Levenspiel, shows how we use tracers to follow the flow of fluids and then we develop a variety of models to represent these flows. This activity is called tracer technology.

Traces of an Omnivore

by Jack Turner Paul Shepard

Paul Shepard is one of the most profound and original thinkers of our time. He has helped define the field of human ecology, and has played a vital role in the development of what have come to be known as environmental philosophy, ecophilosophy, and deep ecology -- new ways of thinking about human-environment interactions that ultimately hold great promise for healing the bonds between humans and the natural world. Traces of an Omnivore presents a readable and accessible introduction to this seminal thinker and writer. Throughout his long and distinguished career, Paul Shepard has addressed the most fundamental question of life: Who are we? An oft-repeated theme of his writing is what he sees as the central fact of our existence: that our genetic heritage, formed by three million years of hunting and gathering remains essentially unchanged. Shepard argues that this, "our wild Pleistocene genome," influences everything from human neurology and ontogeny to our pathologies, social structure, myths, and cosmology. While Shepard's writings travel widely across the intellectual landscape, exploring topics as diverse as aesthetics, the bear, hunting, perception, agriculture, human ontogeny, history, animal rights, domestication, post-modern deconstruction, tourism, vegetarianism, the iconography of animals, the Hudson River school of painters, human ecology, theoretical psychology, and metaphysics, the fundamental importance of our genetic makeup is the predominant theme of this collection. As Jack Turner states in an eloquent and enlightening introduction, the essays gathered here "address controversy with an intellectual courage uncommon in an age that exults the relativist, the skeptic, and the cynic. Perused with care they will reward the reader with a deepened appreciation of what we so casually denigrate as primitive life -- the only life we have in the only world we will ever know."

Traces of Common Xylophagous Insects in Wood: Atlas of Identification - Western Europe

by Magali Toriti Aline Durand Fabien Fohrer

This atlas presents a concrete tool to identify xylophagous activity by the remains they left in wooded areas in Western Europe. Xylophagous insects are among the largest predators of woody tissues. They leave discriminating traces, different for each species according to their bioecology, and so it is necessary to know how to recognize and characterize them. The book is a practical tool to help identify and interpret them through a standardized presentation of the most ubiquitous families and a key to their determination. It presents descriptions of the galleries and of morphometry of the faecal pellets based on macroscopic features for xylophagous identification, and includes information about the origin and distribution of the xylophagous biological cycles, bioclimatic conditions and bioecology, and the type of woods that are attacked. The book will be a useful guide for forest managers, heritage conservationists, environmental engineers, bioarchaeologists, entomologists, loggers, and wood anatomists.

Traces of the Ice Age: Landscape Forms in Central Europe

by Wolfgang Fraedrich

At present, we have been living in an ice age for around 2.5 million years, a geological epoch in which there is ice on Earth and in which the curve of the global mean temperature is subject to significant fluctuations (current trend: temperature increase). At nearly 16 million square kilometers, about ten percent of the land surface is currently covered by glacial ice-and glacial ice plays a major role in shaping landscapes. This compact textbook sharpens the eye for such landscapes. It makes the forms and the shaping processes comprehensible, which the author illustrates with numerous regional examples, especially from Central Europe, such as the North German Plain and the Alpine foothills, but also from Iceland. What traces have the glaciers and their meltwaters left behind? What formation processes can be inferred? How can recent climate history, in particular that of the Ice Age, be reconstructed? It is exciting to look at current developments in glaciated areas and also to take a look at the (climate) future of the Earth. For example, the question arises as to what influence glaciers have on sea level and on future climate change. In this context, natural processes such as the ice age cycles, for which there are various ice age formation hypotheses, and anthropogenic influences in global warming must be weighed against each other.

Traces on the Rhodian Shore: Nature and Culture in Western Thought from Ancient Times to the End of the Eighteenth Century, First Edition

by Clarence J. Glacken

From the time of the Greeks to our own, answers to these questions have been and are being given so frequently and so continually that we may restate them in the form of general ideas: the idea of a designed earth; the idea of environmental influence; and the idea of man as a geographic agent. first owes much to mythology, theology, and philosophy; the second, to pharmaceutical lore, medicine, and weather observation; the third, to the plans, activities, and skills of everyday life such as cultivation, carpentry, and weaving.

Tracing Technologies: Prisoners' Views in the Era of CSI

by Barbara Prainsack Helena Machado

The real heroes of television crime shows in the twenty-first century are no longer police detectives but forensic technologies. The immense popularity of high-tech crime television shows has changed the way in which crime scene work is viewed. The term 'CSI-effect' was coined to signify a situation where people's views and practices have been influenced by such media representations, e.g. judges and jurors putting more weight on forensic evidence that has been produced with high-tech tools - in particular, DNA evidence - than on other kinds of evidence. While considerable scholarly attention has been paid to examining the CSI effect on publics, jurors, judges, and police investigators, prisoners' views on forensic technologies and policing have been under-explored. Drawing on a research sample of over 50 interviews carried out with prisoners in Portugal and Austria, this groundbreaking book shows how prisoners view crime scene traces, how they understand crime scene technologies, and what effect they attribute to the existence of large police databases on their own lives, careers, and futures. Through critically engaging with STS, sociological and criminological perspectives on the use of DNA technologies within the criminal justice system, this work provides the reader with valuable insights into the effect of different legal, political, discursive, and historical configurations on how crime scene technologies are utilized by the police and related to by convicted offenders.

Tracing the Life Cycle of Ideas in the Humanities and Social Sciences: A Portrait Of A Discipline Through Analyses Of Scientific Literature (Quantitative Methods in the Humanities and Social Sciences)

by Arjuna Tuzzi

This book demonstrates how quantitative methods for text analysis can successfully combine with qualitative methods in the study of different disciplines of the Humanities and Social Sciences (HSS). The book focuses on learning about the evolution of ideas of HSS disciplines through a distant reading of the contents conveyed by scientific literature, in order to retrieve the most relevant topics being debated over time. Quantitative methods, statistical techniques and software packages are used to identify and study the main subject matters of a discipline from raw textual data, both in the past and today. The book also deals with the concept of quality of life of words and aims to foster a discussion about the life cycle of scientific ideas. Textual data retrieved from large corpora pose interesting challenges for any data analysis method and today represent a growing area of research in many fields. New problems emerge from the growing availability of large databases and new methods are needed to retrieve significant information from those large information sources. This book can be used to explain how quantitative methods can be part of the research instrumentation and the "toolbox" of scholars of Humanities and Social Sciences. The book contains numerous examples and a description of the main methods in use, with references to literature and available software. Most of the chapters of the book have been written in a non-technical language for HSS researchers without mathematical, computer or statistical backgrounds.

Tracing the Sources and Fate of Contaminants in Agroecosystems: Applications of Multi-stable Isotopes

by Lee Heng Joseph Adu-Gyamfi Grzegorz Skrzypek Gwenaël Imfeld

The objective of this open access book is to present protocols, methodologies, and standard operating procedures (SOPs) used for the identification of sources, transport, and fate of agro-contaminants and illustrate them with several case studies of successful applications. The Soil and Water Management & Crop Nutrition (SWMCN) Subprogramme of the Joint Food and Agriculture Organization (FAO)/International Atomic Energy Agency (IAEA) Centre of Nuclear Techniques in Food and Agriculture, through a Coordinated Research Project (CRP) in partnership with national and international research institutes, developed and evaluated a set of analytical techniques (the toolbox). The toolbox integrates multiple isotope tracers that provide information on the origins and pathways of multiple pollutants through agro-ecosystems, thereby providing more accurate guidance on mitigations. However, land management strategies to address and control the transport of pollutants from soil to water bodies remain the shared responsibility of farm and aquaculture operators, agro-chemical manufacturers, and policymakers in food and agriculture as well as the mining sectors. This book is structured into eight chapters covering (i) an overview of the book’s content, (ii) guidelines for designing water sampling programmes, (iii) the use of mixing models applicable to tracers for water pollution studies, (iv) compound-specific isotope analyses to investigate pesticide degradation in agricultural catchments, (v) the use of stable oxygen isotope composition of phosphate to investigate phosphorous in soil-plant continuum, (vi) the use of stable sulphur isotopes to disentangle agro-pollutants from other contaminants, (vii) nuclear tools used in sediment source apportionment, and (viii) the conclusions and perspectives forward. The book offers up-to-date information, and we hope it is a great source of information for students, researchers, and policymakers. The SWMCN subprogramme thanks all the contributors involved in the preparation of this publication.
