Dragonflies at a Biogeographical Crossroads: The Odonata of Oklahoma and Complexities Beyond Its Borders
by Brenda D. Smith Michael A. PattenThis lavishly illustrated book examines the distribution, ecology, conservation status, and biogeography of 176 species of dragonflies in the southern plains of the United States, where twelve ecoregions converge. The topics discussed, such as phenotypic variation and ecology, are applicable and of interest across the United States and much of north America, and will appeal to researchers and dragonfly enthusiasts alike. A series of maps, including a distributional map by specific locality of occurrence, indicate level of documentation and allow the reader to visualize the biogeographical associations of a given species. These maps also encourage citizen scientists to contribute documentation wherever they spend time in the field. Context-driven chapters, including one on the region’s rich paleontological history, blend environmental history and biogeography, giving the book a fresh perspective on the natural world while providing a rich summary of the odonates. Dragonflies at a Biographical Crossroads: The Odonata of Oklahoma and Complexities Beyond Its Borders will be sought out by dragonfly researchers and enthusiasts, entomologists, amateur naturalists, paleontologists, conservation biologists, educators, regional historians, and those seeking to meld the disciplines of cultural and environmental history with biology. It will also be readily accessible to the lay public. Dragonflies combine the visually stunning with acrobatic fireworks in ways no other insect can hope to combine.

This volume provides fully illustrated and up-to-date keys for all dragonfly genera with descriptive text for each genus, accompanied by distribution maps and 1,595 diagnostic illustrations, including wing patterns and characteristics of the genitalia.For entomologists, limnologists, and ecologists, Dragonfly Genera of the New World is an indispensable resource for field identification and laboratory research.
Dragonfly Nymphs of North America: An Identification Guide
by Kenneth J. TennessenThis monograph is the first of its kind devoted entirely to the dragonfly nymphs of North America north of Mexico, the focus being accurate identification of the 330 species of Anisoptera that occur in the region. Nymphal external morphology is described and illustrated in detail, and all terms needed to navigate the dichotomous keys are defined. Species are tabulated with references that provide the most detailed, accurate descriptions for each; species that are inadequately described are so indicated. The key separating the seven families in the region contains several new characters. The families are then covered separately: Aeshnidae (13 genera), Gomphidae (17 genera), Petaluridae (2 genera), Cordulegastridae (2 genera), Macromiidae (2 genera), Corduliidae (7 genera), and Libellulidae (29 genera). Each family is further characterized, followed by a generic key. A drawing of the habitus and diagnostic details for each genus are provided, along with additional diagnostic remarks and notes on habitat and life cycle; for each genus, a map shows its geographic distribution in North America. Full-grown nymphs of all known species of each genus are keyed and diagnosed; characters that apply to earlier instars are noted. Morphological variation in character states was analyzed in order to assess the reliability of previously utilized characters and to discover new characters. Most of the characters used to distinguish all levels of taxa are illustrated; a total of 702 figures, comprising 1,800 original drawings, along with selected photographs where necessary for clarity, accompany the keys. Measurements of total length, head width, and other variables for each species are provided in tables. Difficulties with past keys and descriptions, including errors, omissions and other shortcomings, are addressed. The importance of nymph characters in helping solve generic and specific distinctions and their role in phylogenetic studies is emphasized. Methods for collecting, rearing, and preserving dragonfly nymphs and exuviae are presented. The final chapter discusses research opportunities on North American Anisoptera nymphs, including taxonomic needs, studies on structure and function, life history and microhabitat, water quality indices and conservation efforts. The habitus drawings of all genera are arranged according to family in five plates (Appendix I); although the book is intended as a lab manual, these plates conveniently allow for comparison based on nymph shape making field identification to genus possible in many cases. Appendix II contains a brief history of dragonfly nymph studies in North America. A glossary and an index to scientific names are included.

Drainage Basin Dynamics: An Introduction to Morphology, Landscape and Modelling (Geography of the Physical Environment)
by Pravat Kumar Shit Biswajit Bera Aznarul Islam Sandipan Ghosh Gouri Sankar BhuniaThis volume provides a versatile introduction to the study of drainage basin evolution, morphology, drainage basin hydrology and sedimentology, human interference, natural and anthropogenic hazards and various management techniques. This book offers the responsible factors of sediment yield and their absolute and specific growth and rate of delivery through tributaries to the main streams. Rivers are important geomorphic agents which reflect an amazing variety of form and behaviour, showing the wide range of natural environment in which they are originated. The drainage system evolution and spatial network development within the dynamic nature are being discussed and how they are adjusted in the geomorphic time scale over the millions of years. This book shows how drainage systems function and react to change and why this thoughtful is required for flourishing integrated basin management. In tropical and sub-tropical countries population pressures as well as different developmental projects are being executed on the drainage basin without proper planning. Today scientists consider drainage basin as an administrative unit during implementation of regional projects. In this context this book will carry a bench mark for scholars and young scientists.
The Draining of the Fens: Projectors, Popular Politics, and State Building in Early Modern England (Johns Hopkins Studies in the History of Technology)
by Eric H. AshHow landowners, drainage projectors, and investors worked with the Crown to transform England's waterlogged Fens.2017 Choice Outstanding Academic TitleThe draining of the Fens in eastern England was one of the largest engineering projects in seventeenth-century Europe. A series of Dutch and English "projectors," working over several decades and with the full support of the Crown, transformed hundreds of thousands of acres of putatively barren wetlands into dry, arable farmland. The drainage project was also supposed to reform the sickly, backward fenlanders into civilized, healthy farmers, to the benefit of the entire commonwealth. As projectors reconstructed entire river systems, these new, artificial channels profoundly altered both the landscape and the lives of those who lived on it. In this definitive account, historian Eric H. Ash provides a detailed history of this ambitious undertaking. Ash traces the endeavor from the 1570s, when draining the whole of the Fens became an imaginable goal for the Crown, through several failed efforts in the early 1600s. The book closes in the 1650s, when, in spite of the project's enormous difficulty and expense, the draining of the Great Level of the Fens was finally completed. Ash ultimately concludes that the transformation of the Fens into fertile farmland had unintended ecological consequences that created at least as many problems as it solved.Drawing on painstaking archival research, Ash explores the drainage from the perspectives of political, social, and environmental history. He argues that the efficient management and exploitation of fenland natural resources in the rising nation-state of early modern England was a crucial problem for the Crown, one that provoked violent confrontations with fenland inhabitants, who viewed the drainage (and accompanying land seizure) as a grave threat to their local landscape, economy, and way of life. The drainage also reveals much about the political flash points that roiled England during the mid–seventeenth century, leading up to the violence of the English Civil War. This is compelling reading for British historians, environmental scholars, historians of technology, and anyone interested in state formation in early modern Europe.
Drama, Politics, and Evolution: Cliodynamics in Play (Cognitive Studies in Literature and Performance)
by Bruce McConachieThis book outlines the evolution of our political nature over two million years and explores many of the rituals, plays, films, and other performances that gave voice and legitimacy to various political regimes in our species’ history. Our genetic and cultural evolution during the Pleistocene Epoch bestowed a wide range of predispositions on our species that continue to shape the politics we support and the performances we enjoy. The book’s case studies range from an initiation ritual in the Mbendjela tribe in the Congo to a 1947 drama by Bertolt Brecht and include a popular puppet play in Tokugawa Japan. A final section examines the gradual disintegration of social cohesion underlying the rise of polarized politics in the USA after 1965, as such films as The Godfather, Independence Day, The Dark Knight Rises, and Joker accelerated the nation’s slide toward authoritarian Trumpism.
Dramatic Effect of Cross-Correlations in Random Vibrations of Discrete Systems, Beams, Plates, and Shells
by Isaac ElishakoffThis volume explains the dramatic effect of cross-correlations in forming the structural response of aircraft in turbulent excitation, ships in rough seas, cars on irregular roads, and other dynamic regimes. It brings into sharp focus the dramatic effect of cross correlations often neglected due to the analytical difficulty of their evaluation. Veteran author Professor Isaac Elishakoff illustrates how neglect of cross correlations could result in underestimation of the response by tens or hundreds of percentages the effect of the random vibrations of structures’ main elements, including beams, plates, and shells.
The Drava River: Environmental Problems and Solutions (Springer Geography)
by Dénes LóczyThis monograph summarizes the environmental issues concerning the channel and the floodplain of the Drava River. It describes the diverse forms of human impact (river regulation, damming and reservoirs, dredging etc.) and the environmental changes of hydrological regime, sediment transport, biodiversity etc. involved. The transboundary nature of the river is emphasized and the resulting problems are outlined. Special attention is devoted to the evolution and present condition of the floodplain (drainage pattern, oxbow lakes and their vegetation). The possible solutions to environmental problems are illustrated by a review of ongoing and planned rehabilitation measures. The book is amply illustrated with maps, cross/sections, diagrams and photographs. The international team of authors (representing all countries crossed by the Drava River: Austria, Slovenia, Croatia and Hungary) approach the topic from different aspects. Thus, the reader is provided with a comprehensive picture of this, up until now, little studied European river.

Drawing Physics: 2,600 Years of Discovery From Thales to Higgs
by Don S. LemonsHumans have been trying to understand the physical universe since antiquity. Aristotle had one vision (the realm of the celestial spheres is perfect), and Einstein another (all motion is relativistic). More often than not, these different understandings begin with a simple drawing, a pre-mathematical picture of reality. Such drawings are a humble but effective tool of the physicist's craft, part of the tradition of thinking, teaching, and learning passed down through the centuries. This book uses drawings to help explain fifty-one key ideas of physics accessibly and engagingly. Don Lemons, a professor of physics and author of several physics books, pairs short, elegantly written essays with simple drawings that together convey important concepts from the history of physical science.Lemons proceeds chronologically, beginning with Thales' discovery of triangulation, the Pythagorean monocord, and Archimedes' explanation of balance. He continues through Leonardo's description of "earthshine" (the ghostly glow between the horns of a crescent moon), Kepler's laws of planetary motion, and Newton's cradle (suspended steel balls demonstrating by their collisions that for every action there is always an equal and opposite reaction). Reaching the twentieth and twenty-first centuries, Lemons explains the photoelectric effect, the hydrogen atom, general relativity, the global greenhouse effect, Higgs boson, and more. The essays place the science of the drawings in historical context -- describing, for example, Galileo's conflict with the Roman Catholic Church over his teaching that the sun is the center of the universe, the link between the discovery of electrical phenomena and the romanticism of William Wordsworth, and the shadow cast by the Great War over Einstein's discovery of relativity. Readers of Drawing Physics with little background in mathematics or physics will say, "Now I see, and now I understand."

McElheny also shows that the Human Genome Project is a striking example of how new techniques (such as restriction enzymes and sequencing methods) often arrive first, shaping the questions scientists then ask.Drawing on years of original interviews and reporting in the inner circles of biological science, Drawing the Map of Life is the definitive, up-to-date story of today's greatest scientific quest. No one who wishes to understand genome mapping and how it is transforming our lives can afford to miss this book.
Drawing the Map of Life
by Victor K. McelhenyScience journalist McElheny charts the history of the human genome project from the discovery of DNA less than sixty years ago to the real possibility of recreating our own genetic coding. Along the way he puts faces to the scientists working on the project. He also covers the political and ethical debates. For some of the researchers, the search was intensified by personal experiences. One had a brother with Down Syndrome, another a child with schizophrenia. The wide-ranging possibilities of genetic manipulation are discussed, including retro-viruses to treat cancer and AIDS and increase food production. For the most part, McElheny concentrates on telling the story without becoming embroiled in the ethical and religious controversies surrounding the topic.

A Dream of Flight: Alberto Santos-Dumont's Race Around the Eiffel Tower
by Jef Polivka Rob PolivkaDebut nonfiction duo Rob and Jef Polivka offer an illustrated madcap adventure in A Dream of Flight, a dynamic biography of Alberto Santos-Dumont, an inventor who risked everything to reach the skies. And sure enough, his successes and failures brought the world’s people closer together.Ready? Set. Fly! At the turn of the twentieth century, no aviation prize was more coveted in Europe than the Deutsch Prize. To win it, a pilot would have to fly a balloon from Paris’s Aero Club around the Eiffel Tower and back in thirty minutes or less. Who would be the first to succeed?Alberto Santos-Dumont thought he could. His latest design, Airship No. 6, was perfected from the countless lessons he learned during previous crashes. On the morning of October 19, 1901, Santos was making good time in the race when disaster struck—his motor had sputtered to a stop mid-air! Would Santos make it to the finish line in time—let alone survive?
The Dream Universe: How Fundamental Physics Lost Its Way
by David LindleyA vivid and captivating narrative about how modern science broke free of ancient philosophy, and how theoretical physics is returning to its unscientific rootsIn the early seventeenth century Galileo broke free from the hold of ancient Platonic and Aristotelian philosophy. He drastically changed the framework through which we view the natural world when he asserted that we should base our theory of reality on what we can observe rather than pure thought. In the process, he invented what we would come to call science. This set the stage for all the breakthroughs that followed--from Kepler to Newton to Einstein. But in the early twentieth century when quantum physics, with its deeply complex mathematics, entered into the picture, something began to change. Many physicists began looking to the equations first and physical reality second. As we investigate realms further and further from what we can see and what we can test, we must look to elegant, aesthetically pleasing equations to develop our conception of what reality is. As a result, much of theoretical physics today is something more akin to the philosophy of Plato than the science to which the physicists are heirs. In The Dream Universe, Lindley asks what is science when it becomes completely untethered from measurable phenomena?
Dreamers, Visionaries, and Revolutionaries in the Life Sciences
by Oren Harman Michael R. DietrichWhat are the conditions that foster true novelty and allow visionaries to set their eyes on unknown horizons? What have been the challenges that have spawned new innovations, and how have they shaped modern biology? In Dreamers, Visionaries, and Revolutionaries in the Life Sciences, editors Oren Harman and Michael R. Dietrich explore these questions through the lives of eighteen exemplary biologists who had grand and often radical ideas that went far beyond the run-of-the-mill science of their peers. From the Frenchman Jean-Baptiste Lamarck, who coined the word “biology” in the early nineteenth century, to the American James Lovelock, for whom the Earth is a living, breathing organism, these dreamers innovated in ways that forced their contemporaries to reexamine comfortable truths. With this collection readers will follow Jane Goodall into the hidden world of apes in African jungles and Francis Crick as he attacks the problem of consciousness. Join Mary Lasker on her campaign to conquer cancer and follow geneticist George Church as he dreams of bringing back woolly mammoths and Neanderthals. In these lives and the many others featured in these pages, we discover visions that were sometimes fantastical, quixotic, and even threatening and destabilizing, but always a challenge to the status quo.
