Drachenzucht für Einsteiger: Ein "gefährlicher" Zeitvertreib für Hobby-Genetiker
by Paul Knoepfler Julie KnoepflerKann man einen Drachen züchten? Kann er dann Feuer spucken und fliegen? Können wir ihm eine eindrucksvolle Größe verleihen? Wie schlau sollen wir unseren Drachen machen, und können wir ihn trainieren? Wie wahrscheinlich ist es, dass wir bei unserem Versuch, einen Drachen zu bauen, umkommen? Und geht das auch mit Einhörnern?Die Welt begeistert sich seit Jahrhunderten für Drachen und sie haben noch immer einen festen Platz in der Popkultur wie Smaug in „Der kleine Hobbit“ und die Drachen in „Game of Thrones“. Die Leute lieben Drachen und sind neugierig zu erfahren, ob man tatsächlich einen Drachen erschaffen kann. In diesem ungewöhnlichen Buch geht es darum, wie wir mit den allerneuesten wissenschaftlichen Techniken theoretisch einen Drachen erschaffen könnten. Dabei behandeln wir modernste wissenschaftliche Themen wie CRISPR, Biohacking, Stammzellenforschung und Bioengineering. Das Buch steckt voller Fakten, doch der Humor kommt nicht zu kurz, und es regt Leser*innen überdies an, sich Gedanken über den Einfluss von Wissenschaft und Technik auf unsere Gesellschaft zu machen. Unterwegs wirft das Buch einen satirischen Blick auf die Wissenschaft an vorderster Front, die oft in den Medien maßlos gehypt wird. Es diskutiert Schlüsseltechnologien, die ins Spiel kommen, wenn wir uns vorstellen, unsere Idee, einen Drachen zu bauen, in feuerspuckende Realität umzusetzen. Während wir all diese Themen diskutieren, sprechen wir auch über die ethischen Probleme, die sich beim „Bau“ eines Drachens ergeben, und die Möglichkeiten, einen ähnlichen Ansatz zu nutzen, um andere mythische Wesen, wie z.B. ein Einhorn, zu erschaffen. Dieses Buch, das jeden ansprechen sollte, enthält viele eindrucksvolle Illustrationen und andere interessante Abbildungen, darunter Drachendarstellungen, Bilder von Flugsaurierskeletten und vieles mehr.

Dragon Songs: Love and Adventure among Crocodiles, Alligators, and Other Dinosaur Relations
by Vladimir DinetsA born naturalist and a fearless traveler, Vladimir Dinets wrote travel guides, conducted field research, and lived a couple of lives before he was accepted into the PhD program in zoology at the University of Miami. He thought crocodiles were a dead-end research topic--survivors from the age of the dinosaurs but not much else--until he witnessed groups of up to seventy alligators performing mating choruses that included infrasound vibrations--a form of communication extremely rare in nature--and a "dance" unknown in the scientific literature but that resembled a scene from Jurassic Park. To prove his thesis about the language of crocodiles, he spent the next six years traveling around the world on shoestring budgets and in extreme circumstances, studying almost every living species. At the same time, as a man desiring companionship in life, he sought love.With adventures on five continents, Dragon Songs is his account of this quest. It includes an escape from a boiling lava lake in the Afar Desert, being chased up a tree by a tiger in India, hitching a ride with a cocaine smuggler in Bolivia, and diving with giant Greenland sharks--all in the name of studying crocodiles, among which he routinely paddled in his inflatable kayak. Of course, not everything went according to plan. But, in the end, his ground-breaking research helped change the field. And during the course of his adventures, he met and courted his future wife.
Dragon Walk: On Reef Recovery & Political Will
by Robert WintnerThe three main hubs of aquarium trade devastation are Indonesia, the Philippines, and Hawaii. Each has its own sad story of political corruption and theft of natural resources to benefit a greedy, ruthless few. Yet, despite facing a litany of challenges, each hub shows faint hope for progress: with Komodo National Park in Indonesia, a few bright lights in the development of Philippine reef management, and an anti-aquarium campaign taking hold in Hawaii. A beautiful coffee table photo book is one thing. Dragon Walk is a political grenade, willing to name culprits, political assassins, and nitwits with less spinal fortitude than most invertebrates. Dragon Walk is far more vital; a no-holds-barred grapple with evil and reef devastation that shines a light where others fear to tread.

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 Sandipan Ghosh Aznarul Islam Gouri Sankar Bhunia Pravat Kumar Shit Biswajit BeraThis 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.
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.
