Flying with Feathers and Wings by Caitie McAneney Pdf
How do animals such as birds, insects, and bats stay in the air? The answer of course is wings and feathers. Wings and feathers are important adaptations that have taken millions of years evolve. Feathers first appeared during the time of the dinosaurs, and birds are actually distant relatives of dinosaurs. Insects with wings appeared many thousands of years before feathers appeared. This book discusses how these adaptations benefit the birds, insects, and other animals that possess them. Vibrant photographs of flying animals are paired with manageable text to make this book both educational and engaging.
Have you ever wished you could fly? Many animals have wings that help them soar through the air. But some animals have other uses for their wings, like swimming! Full-color illustrations and music help readers discover how animals have adapted their wings for different uses. Animal Wings is aligned with the Next Generation Science Standards. This hardcover book comes with CD and online music access.
Animal Locomotion by Malcolm S. Gordon,Reinhard Blickhan,John O. Dabiri,John J. Videler Pdf
Animal Locomotion: Physical Principles and Adaptations is a professional-level, state of the art review and reference summarizing the current understanding of macroscopic metazoan animal movement. The comparative biophysics, biomechanics and bioengineering of swimming, flying and terrestrial locomotion are placed in contemporary frameworks of biodiversity, evolutionary process, and modern research methods, including mathematical analysis. The intended primary audience is advanced-level students and researchers primarily interested in and trained in mathematics, physical sciences and engineering. Although not encyclopedic in its coverage, anyone interested in organismal biology, functional morphology, organ systems and ecological physiology, physiological ecology, molecular biology, molecular genetics and systems biology should find this book useful.
Marcel the swan stays behind when his family migrates for the winter, but soon finds he cannot find food and shelter the way other animals do in the winter.
From one of Canada's most exciting writers and ecological thinkers, a book that changes the way we see nature and shows that in restoring the living world, we are also restoring ourselves. The Once and Future World began in the moment J.B. MacKinnon realized the grassland he grew up on was not the pristine wilderness he had always believed it to be. Instead, his home prairie was the outcome of a long history of transformation, from the disappearance of the grizzly bear to the introduction of cattle. What remains today is an illusion of the wild--an illusion that has in many ways created our world. In three beautifully drawn parts, MacKinnon revisits a globe exuberant with life, where lions roam North America and 20 times more whales swim in the sea. He traces how humans destroyed that reality, out of rapaciousness, yes, but also through a great forgetting. Finally, he calls for an "age of restoration," not only to revisit that richer and more awe-filled world, but to reconnect with our truest human nature. MacKinnon never fails to remind us that nature is a menagerie of marvels. Here are fish that pass down the wisdom of elders, landscapes still shaped by "ecological ghosts," a tortoise that is slowly remaking prehistory. "It remains a beautiful world," MacKinnon writes, "and it is its beauty, not its emptiness, that should inspire us to seek more nature in our lives."
This book outlines the principles of flight, of birds in particular. It describes a way of simplifying the mechanics of flight into a practical computer program, which will predict in some detail what any bird, real or hypothetical, can and cannot do. The Flight program, presented on the companion website, generates performance curves for flapping and gliding flight, and simulations of long-distance migration and accounts successfully for the consumption of muscles and other tissues during migratory flights. The program is effectively a working model of a flying bird (or bat or pterosaur) and is the skeleton around which the book is built. The book provides a wider background and then explains how Flight works and shows how to set up and test hypotheses generated by the program. The book and the program are based on adapting the conventional (and well-tested) thinking of aeronautical engineers to the biological problems of bird flight. Their primary aim is to convince biologists that this is the appropriate way to handle problems that involve flight, to make the engineering background accessible to biologists, and to provide a tool kit in the shape of the Flight program, which they can use to solve practical problems involving bird flight and migration. In addition, the book will be readily accessible to engineers who want to know how birds work, and should be of interest to the ever-growing community working on flapping "micro air vehicles" (MAVs). The program can be used to predict the flight performance and capabilities of reconstructed fossil birds and pterosaurs, flying in ancient atmospheres that differ from present conditions, and also, of course, to predict and account for the results of experiments and observations on living birds and bats. * An up to date work by the world's leading expert on bird flight * Examines the biology and biomechanics of bird flight with added reference to the flight of bats and pterosaurs. * Uses proven aeronautical principles to help solve biological issues in understanding and predicting the flight capabilities of birds and other vertebrates. * Provides insights into the evolution of flight and the likely capabilities of extinct birds and reptiles. * Gives a detailed explanation of the science behind, and use of, the author's predictive bird flight simulation program - Flight - which is available on a companion website. * Presents often difficult concepts in easily understood language.
Did you know that many species are able to glide through the air using loose flaps of skin or other adaptations? This is called passive flight because the animal does not need to use its own energy to stay in the air. Discover these and other intriguing facts in Flight.

Introducing Social Change by Conrad M. Arensberg Pdf
The development of industry in Europe and the United States has resulted in great marvels of production. However, non-Western nations, with a few exceptions, have not yet shared fully in this productivity, despite the desires of their leaders to do so. Also, in the United States, and in other industrial nations, there are sizeable minority groups which have not been fully assimilated into the productive pattern of the majority. Most live as poverty enclaves within the greater society. This socioeconomic imbalance has contributed to unrest in both the agrarian and industrial nations.Introducing Social Change deals with numerous topics of social change: cultural problems of change in general; a description of the concept of culture; a discussion of cultural change in its various forms; an introduction to the process of directed change; a discussion of the motivation necessary to bring about change; a treatment of the method of adapting an innovation to existing ideas and customs; the profile of the primary characteristics of most developing nations; the main characteristics and cultural values of America as a sample urban, industrial culture; and field problems of the change agent, and in particular those methods from anthropology that can be modified for use.Developments in the industrial countries, particularly the United States, have demonstrated the need for this second edition. When the original version was produced, little thought or activity was given to development efforts among ethnic minorities of industrial countries. Development was thought of almost exclusively as an activity relevant to the developing, non-industrial nations. It has become apparent that ethnic groups in industrial nations are also in need of economic development. Government policies, including funding, have been increasingly pointed in this direction.
The strange bodies animals have developed over time are endlessly fascinating. The hammerhead shark’s odd head may look strange, but it helps the shark see all around itself. The ugly face of the puss moth caterpillar helps keep predators away, and the scorpion’s deadly tail can do some damage despite how bizarre it may look. Many questions readers may have about some of the most extreme animal anatomy can be answered in this volume, which includes up-close photographs of some pretty dangerous animals as well as thorough explanations of why they look the way they do.
