Download or read book Handbook of Genetics written by Robert King and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 664 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the first four volumes of the Handbook of Genetics is to bring together collections of relatively short, authoritative essays or an notated compilations of data on topics of significance to geneticists. Many of the essays will deal with various aspects of the biology of certain species or species groups selected because they are favorite subjects for genetic investigation in nature or the laboratory. Often there will be an encyclo pedic amount of information available on such species, with new papers appearing daily. Most of these will be written for specialists in a jargon that is bewildering to a novice, and sometimes even to a veteran geneticist working with evolutionarily distant organisms. For such readers what is needed is a written introduction to the morphology, life cycle, reproductive behavior, and culture methods for the species in question. What are its particular advantages (and disadvantages) for genetic study, and what have we learned from it? Where are the classic papers, the key bibli ographies, and how does one get stocks of wild type or mutant strains? Lists giving the symbolism and descriptions for selected mutants that have been retained and are thus available for future studies are provided whenever possible. Genetic and cytological maps, mitotic karyotypes, and haploid DNA values are also included when available. Volume 4 deals with certain vertebrate species that have been studied in considerable detail from the standpoint of genetics or molecular cytogenetics. Such data are available for only a relatively few vertebrates.

Download or read book Fowl Play written by Sally Coulthard and published by Bloomsbury Publishing. This book was released on 2022-10-13 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: From dinosaur to dinner plate, Sally Coulthard tells the fascinating – and sometimes shocking – story of the domestic chicken. The chicken can fly only a few metres but – somehow – this unlikely evolutionary descendant of Tyrannosaurus Rex has conquered the world. Earth is now home to more than twenty billion chickens, at least ten times more than any other bird. For every human on the planet, there are three chickens. In Fowl Play, Sally Coulthard charts the chicken's fascinating journey from dinosaur to domestication to exploitation, exploring every aspect of the history of Gallus gallus domesticus: its importance to the ancient Egyptians, Greeks and Romans as food source and fighting bird; its symbolic roles in religion and folklore and metaphorical function in the language we use; its homely place as egg-providing companion on farms, smallholdings and in suburban back gardens; and its darker modern-day fate as battery bird raised to satisfy society's unquenchable addiction to wings and nuggets. Of all animals, chickens perhaps best represent the contradictory way we humans treat other species; both beloved pet and cheap commodity, symbol of a sustainable good life and brutalised object of factory farming. The chicken is also a bird we feel deeply familiar with and yet know very little about. As informative as it is entertaining, Fowl Play tells a remarkable tale of evolutionary change, epic global travel and ruthless exploitation – as well as of companionship, ingenuity and the folly of human nature.

Available in PDF, EPUB and Kindle. Book excerpt: From award-winning author and ornithologist Tim Birkhead, a sweeping history of the long and close relationship between birds and humans Since the dawn of human history, birds have stirred our imagination, inspiring and challenging our ideas about science, faith, art, and philosophy. We have worshipped birds as gods, hunted them for sustenance, adorned ourselves with their feathers, studied their wings to engineer flight, and, more recently, attempted to protect them. In Birds and Us, award-winning writer and ornithologist Tim Birkhead takes us on a dazzling epic journey through our mutual history with birds, from the ibises mummified and deified by Ancient Egyptians to the Renaissance fascination with woodpecker anatomy—and from the Victorian obsession with egg collecting to today’s fight to save endangered species and restore their habitats. Spanning continents and millennia, Birds and Us chronicles the beginnings of a written history of birds in ancient Greece and Rome, the obsession with falconry in the Middle Ages, and the development of ornithological science. Moving to the twentieth century, the book tells the story of the emergence of birdwatching and the field study of birds, and how they triggered an extraordinary flowering of knowledge and empathy for birds, eventually leading to today’s massive worldwide interest in birds—and the realization of the urgent need to save them. Weaving in stories from Birkhead’s life as scientist, including far-flung expeditions to wondrous Neolithic caves in Spain and the bustling guillemot colonies of the Faroe Islands, this rich and fascinating book is an unforgettable account of how birds have shaped us, and how we have shaped them.

Download or read book Environmental Aspects of Housing for Animal Production written by J. A. Clark and published by Elsevier. This book was released on 2013-10-22 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental Aspects of Housing for Animal Production is concerned with environmental aspects of housing farm animals. The discussions are organized around physical and physiological principles; environmental influences on reproduction; environmental influences on the productivity of farm animals; optimal housing environments for temperate and cool climates; housing environments for hot climates; engineering and control of the house environment; and the constraints of welfare and disease. This text consists of 32 chapters divided into nine sections. The first chapter explores the physiological mechanisms whereby the food- or fiber-producing animals maintain a constant body temperature under climatic extremes and the possible impact that these physiological processes may have on productive systems. This discussion is followed by chapters on the influence of climate on the decision to house livestock; the effect of the environment on animal reproduction; thermal influences on poultry; and the importance of ventilation and temperature control. This text also considers the poultry housing problems in tropical and subtropical climates; insulation of animal houses; and the interaction between feathering and egg production in laying hens. This book will appeal to those working in the field of housing for animal production, both in research and development and at a practical level.
