Berra, whose "Darwin: The Man" lectures are in high demand worldwide, tells the fascinating story of the person and the idea that changed everything. Berra discusses Darwin’s revolutionary scientific work, its impact on modern-day biological science, and the influence of Darwin’s evolutionary theory on Western thought. But Berra digs deeper to reveal Darwin the man by combining anecdotes with carefully selected illustrations and photographs.This small gem of a book includes 20 color plates and 60 black-and-white illustrations, along with an annotated list of Darwin’s publications and a chronology of his life.

    In this collection of essays, Knapp intentionally flies away from the flock, reveling in insights gleaned from birds, his students, and the wide-eyed wonder his children experience.The Delightful Horror of Family Birding navigates the world in hopes that appreciation of nature will burn intensely for generations to come, not peter out in merely a flicker. Whether traveling solo or with his students or children, Knapp levels his gaze on the birds that share our skies, showing that birds can be a portal to deeper relationships, ecological understanding, and newfound joy.

    The book includes charts with the recipes, instructions on keeping diets simple and balanced, guidelines on preparation, suggestions for finding ingredients, and how much to feed a dog by body weight. There are recipes for healthy adult dogs, as well as guidelines for puppies, senior dogs, and dogs with health conditions including pancreatitis, renal problems, gastric issues, allergies, heart disease, liver disease, and cancer.Tracing the history of feeding dogs, the author shows when commercial dog food rose and took hold of the market. She discusses canine nutritional needs and provides research on how home-prepared foods can meet pets' needs better than commercial, processed dog food. Written with thorough information for the seasoned raw feeder, this guide can also be easily followed by any newcomer to home-feeding.This revised edition includes new information on special care and feeding of pregnant, newborn, performance, and toy breed dogs as well as senior dog considerations and the safety of the raw food diet for dogs.From the Trade Paperback edition.

    In the great halls of science, dogma holds that Darwin's theory of natural selection explains every branch on the tree of life: which species thrive, which wither away to extinction, and what features each evolves. But can adaptation by natural selection really account for everything we see in nature? Yale University ornithologist Richard Prum--reviving Darwin's own views--thinks not. Deep in tropical jungles around the world are birds with a dizzying array of appearances and mating displays: Club-winged Manakins who sing with their wings, Great Argus Pheasants who dazzle prospective mates with a four-foot-wide cone of feathers covered in golden 3D spheres, Red-capped Manakins who moonwalk. In thirty years of fieldwork, Prum has seen numerous display traits that seem disconnected from, if not outright contrary to, selection for individual survival. To explain this, he dusts off Darwin's long-neglected theory of sexual selection in which the act of choosing a mate for purely aesthetic reasons--for the mere pleasure of it--is an independent engine of evolutionary change. Mate choice can drive ornamental traits from the constraints of adaptive evolution, allowing them to grow ever more elaborate. It also sets the stakes for sexual conflict, in which the sexual autonomy of the female evolves in response to male sexual control. Most crucially, this framework provides important insights into the evolution of human sexuality, particularly the ways in which female preferences have changed male bodies, and even maleness itself, through evolutionary time. The Evolution of Beauty presents a unique scientific vision for how nature's splendor contributes to a more complete understanding of evolution and of ourselves.

    Get ready to unthink what you thought you knew and journey into the deep, dark depths of the Jurassic.The discovery of the first feathered dinosaur in China in 1996 sent shockwaves through the palaeontological world. Were the feathers part of a complex mating ritual, or a stepping stone in the evolution of flight? And just how closely related is T. rex to a chicken? Award-winning journalist John Pickrell reveals how dinosaurs developed flight and became the birds in our backyards. He delves into the latest discoveries in China, the US, Europe and uncovers a thriving black market in fossils and infighting between dinosaur hunters, plus the controversial plan to use a chicken to bring dinosaurs back from the dead.

    In addition to his day job in the Oxfordshire countryside treating cows, dogs, pigs and cats, he's also worked with an astonishing range of species around the world, including crocodiles, rhinos and pandas. In this charming collection he introduces us to some of his favourite patients, ranging from beloved family pets through to magnificent creatures of the wild. Whether microchipping armadillos, anaesthetising giraffes or advising the makers of the Jurassic World series on exactly how to operate on a velociraptor, Jonathan's love for his work and the entire animal kingdom is infectious. From the preposterous (castrating a sugar glider) to the poignant (encountering victims of rhino poaching), the stories in The Travelling Vet will delight and enthral every animal lover.

    In the bestselling tradition of The Orchid Thief, comes the quirky and dramatic story of the last days of six North American bird species.

    He has observed more than six thousand species during travels that have taken him to every continent. He founded the largest company in the world specializing in birding tours and one of the most respected ones in ecotourism. Emanuel has received some of birding’s highest honors, including the Roger Tory Peterson Award from the American Birding Association and the Arthur A. Allen Award from the Cornell Laboratory of Ornithology. He also started the first birding camps for young people, which he considers one of his greatest achievements.In One More Warbler, Emanuel recalls a lifetime of birding adventures—from his childhood sighting of a male Cardinal that ignited his passion for birds to a once-in-a-lifetime journey to Asia to observe all eight species of cranes of that continent. He tells fascinating stories of meeting his mentors who taught him about birds, nature, and conservation, and later, his close circle of friends—Ted Parker, Peter Matthiessen, George Plimpton, Roger Tory Peterson, and others—who he frequently birded and traveled with around the world. Emanuel writes about the sighting of an Eskimo Curlew, thought to be extinct, on Galveston Island; setting an all-time national record during the annual Audubon Christmas Bird Count; attempting to see the Imperial Woodpecker in northwestern Mexico; and birding on the far-flung island of Attu on the Aleutian chain. Over the years, Emanuel became a dedicated mentor himself, teaching hundreds of young people the joys and enrichment of birding. “Birds changed my life,” says Emanuel, and his stories make clear how a deep connection to the natural world can change everyone’s life.
