Download or read book Appalachian Spring written by Marcia Bonta and published by University of Pittsburgh Press. This book was released on 2010-06-15 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marcia Bonta is a naturalist-writer who has lived on a 500-acre mountain-top farm in central Pennsylvania for twenty years. Appalachian Spring is her personal account of that glorious spectacle - the coming of the spring to the woods and fields of Appalachia.The book begins with spring preliminaries in January and February when gray squirrels mate and the great horned owls conduct their courtship rites. Then, with the onset of true spring, the intricacies of the season unravel day by day in journal entries that combine Bonta's own meticulous observations with the research reported by botanists, entomologists, and other natural scientists.She recounts her hours spent watching an active red fox den or observing the drumming of a male ruffed grouse - all without the benefit of a blind. She discovers new-born fawns on the trail and hen turkeys with their poults in the field. A black bear peers into her sitting room window; deer play tag in her front yard.Birdwatching is an integral part of her spring ritual; she records both the return of nesting species and the passing through of migrants. She spends a blustery St. Patrick's Day following a flock of American pipits foraging in her field, discovers and watches an ovenbird nest beside her trail, and counts twenty-three species of wood warblers during one spectacular day in mid-May.Every aspect of the natural world catches her eye, from tthe life cycle of a tent caterpillar to the sex life of a jack-in-the-pulpit. But while she considers her book to ber her own love sone about the place and season on earth she loves most, she also mourns the continual exploitation of the natural earth by humanity for its own often superficial uses. She hopes, by recounting the wonders of the natural world, to convert others to what she calls the "third stage" in humanity's relationship with nature, that of empathy with all of nature for its own sake. "To know the earth better, to grasp a little of its workings, to look on it with awe and wonder as well as with respect, is to want to save it from destruction."

Download or read book The Snowy Owl written by Eugene Potapov and published by A&C Black. This book was released on 2013-01-17 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive monograph of the beautiful Snowy Owl, famed for its elegant, all-white plumage. The Snowy Owl needs little introduction. This massive white owl breeds throughout the Arctic, wherever there are voles or lemmings to hunt, from Scandinavia through northern Russia to Canada and Greenland. Southerly movements in winter see North American birds travel as far south as the northern United States, while infrequent vagrants on the Shetlands and other northern isles are a magnet for birders. The Snowy Owl gives this popular bird the full Poyser treatment, with sections on morphology, distribution, palaeontology and evolution, habitat, breeding, diet, population dynamics, movements, interspecific relationships and conservation, supported by some fabulous photography. The award-winning author team also had access to Russian research literature, which is generally out of reach for Western scientists.
Download or read book Sex Itself written by Sarah S. Richardson and published by University of Chicago Press. This book was released on 2013-12-13 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human genomes are 99.9 percent identical—with one prominent exception. Instead of a matching pair of X chromosomes, men carry a single X, coupled with a tiny chromosome called the Y. Tracking the emergence of a new and distinctive way of thinking about sex represented by the unalterable, simple, and visually compelling binary of the X and Y chromosomes, Sex Itself examines the interaction between cultural gender norms and genetic theories of sex from the beginning of the twentieth century to the present, postgenomic age. Using methods from history, philosophy, and gender studies of science, Sarah S. Richardson uncovers how gender has helped to shape the research practices, questions asked, theories and models, and descriptive language used in sex chromosome research. From the earliest theories of chromosomal sex determination, to the mid-century hypothesis of the aggressive XYY supermale, to the debate about Y chromosome degeneration, to the recent claim that male and female genomes are more different than those of humans and chimpanzees, Richardson shows how cultural gender conceptions influence the genetic science of sex. Richardson shows how sexual science of the past continues to resonate, in ways both subtle and explicit, in contemporary research on the genetics of sex and gender. With the completion of the Human Genome Project, genes and chromosomes are moving to the center of the biology of sex. Sex Itself offers a compelling argument for the importance of ongoing critical dialogue on how cultural conceptions of gender operate within the science of sex.
