Flight And Adaptation

Wings carry tiny insects, fluttering butterflies, and backyard birds, and they even once propelled some dinosaurs up and through the skies. Find out how, when, and why birds and beasts have taken to the air, and discover how wings work in this informative and brilliantly illustrated book about flight.

An in-depth study of the various aspects of Tibetan refugees, beginning with their flight, resettlement in the Himalayan regions of Darjeeling, Kalimpong, Gangtok, Ravangla(Sikkim) and adaptation to their host environments. Studies from both sociological and anthropological points of view, this study is different from the other studies done on the same subject, in that based on an area physically, culturally and linguistically similar to their homeland.

Biological evolution is a fact—but the many conflicting theories of evolution remain controversial even today. When Adaptation and Natural Selection was first published in 1966, it struck a powerful blow against those who argued for the concept of group selection—the idea that evolution acts to select entire species rather than individuals. Williams’s famous work in favor of simple Darwinism over group selection has become a classic of science literature, valued for its thorough and convincing argument and its relevance to many fields outside of biology. Now with a new foreword by Richard Dawkins, Adaptation and Natural Selection is an essential text for understanding the nature of scientific debate.

Across North America, flocks of birds hurl themselves into airplanes, causing at least a dozen to crash. Thousands of people die. Fearing terrorism, the United States government grounds all flights, and millions of travelers are stranded. Among them are Reese and her debate team partner and longtime crush David, who are in Arizona when the disaster occurs. On their drive home to San Francisco, along a stretch of empty highway in the middle of the Nevada night, a bird flies into their headlights. The car flips over. When they wake up in a military hospital, the doctor won't tell them what happened, where they are--or how they've been miraculously healed. Things become even stranger when Reese returns home. San Francisco feels like a different place with police enforcing curfew, hazmat teams collecting dead birds, and a strange presence that seems to be following her. When Reese unexpectedly collides with the beautiful Amber Gray, her search for the truth is forced in an entirely new direction-and threatens to expose a vast global conspiracy that the government has worked for decades to keep secret. Adaptation is a bold contemporary science-fiction thriller from the acclaimed author of Ash.

It is not often that a century of scholarly activity breaks conveniently into halves, but ornithology of the first half of the 20th century is clearly different from that of the second half. The break actually can be marked in 1949, with the appearance of Meyer and Schuz's Ornithologie ais Biologische Wissenschaft. Prior to this, ornithologists had tended to speak mostly to other ornithologists, experiments (the testing of hy potheses) were uncommon, and a concern for birds as birds was the dominant thread in our thinking. Subsequent to 1949, ornithologists have tended to become ever more professional in their pursuits and to incorporate protocols of experimental biology into their work; more importantly perhaps, they have begun to show a concern for birds as agencies for the study of biology. Many of the most satisfying of recent ornithological studies have come from reductionist research ap proaches, and have been accomplished by specialists in such areas as biochemistry, ethology, genetics, and ecology. A great many studies routinely rely on statistical hypothesis testing, allowing us to come to conclusions unmarred by wishful thinking. Some of us are ready to tell the world that we are a "hard" science, and perhaps that time is not so very far off for most of us. Volume 2 examines several solid examples of late 20th-century ornithology.

Human Adaptation to Spaceflight: The Role of Nutrition reflects a (brief) review of the history of and current state of knowledge about the role of nutrition in human space flight. We have attempted to morganize this from a more physiological point of view, and to highlight systems, and the nutrients that support them, rather than the other way around. We hope we have captured in this book the state of the field of study of the role of human nutrition in space flight, along with the work leading up to this state, and some guideposts for work remaining to be done and gaps that need to be filled.

This book discusses biochemical adaptation to environments from freezing polar oceans to boiling hot springs, and under hydrostatic pressures up to 1,000 times that at sea level. Originally published in 1984. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
