A Polar Affair by Lloyd Spencer Davis Pdf

A captivating blend of true adventure and natural history by one of today’s leading penguin experts and Antarctic explorers. George Murray Levick was the physician on Robert Falcon Scott’s tragic Antarctic expedition of 1910. Marooned for an Antarctic winter, Levick passed the time by becoming the first man to study penguins up close. His findings were so shocking to Victorian morals that they were quickly suppressed and seemingly lost to history. A century later, Lloyd Spencer Davis rediscovers Levick and his findings during the course of his own scientific adventures in Antarctica. Levick’s long-suppressed manuscript reveals not only an incredible survival story, but one that will change our understanding of an entire species. A Polar Affair reveals the last untold tale from the Heroic Age of Antarctic Exploration. It is perhaps the greatest of all of those stories—but why was it hidden to begin with? The ever-fascinating and charming penguin holds the key. Moving deftly between both Levick’s and Davis’s explorations, observations, and comparisons in biology over the course of a century, A Polar Affair reveals cutting-edge findings about ornithology, in which the sex lives of penguins are the jumping-off point for major new insights into the underpinnings of evolutionary biology itself.

The Behavior of Penguins by Dietland Muller-Schwarze Pdf

"Strange geese." That was their description when they were discovered in 1520 during Magellan's historic voyage. Today, penguins are familiar to everyone, yet few researchers have observed them in the remote regions in which they live. Written by an ecologist-behaviorist who has worked extensively in the natural penguin habitat, The Behavior of Penguins is the first general work on the entire family of penguins. Numerous and remarkable field photographs document the author's detailed study of the life cycles and breeding patterns of each penguin species. He brings to light their unusual abilities to go with little food for months, to dive deep in the ocean, and to protect themselves in extreme environments. Müller-Schwarze's comprehensive and fascinating account of penguins also emphasizes the urgent need to protect these birds and their natural habitat.

The Truth About Animals by Lucy Cooke Pdf

Mary Roach meets Bill Bryson in this "surefire summer winner" (Janet Maslin, New York Times), an uproarious tour of the basest instincts and biggest mysteries of the animal world Humans have gone to the Moon and discovered the Higgs boson, but when it comes to understanding animals, we've still got a long way to go. Whether we're seeing a viral video of romping baby pandas or a picture of penguins "holding hands," it's hard for us not to project our own values--innocence, fidelity, temperance, hard work--onto animals. So you've probably never considered if moose get drunk, penguins cheat on their mates, or worker ants lay about. They do--and that's just for starters. In The Truth About Animals, Lucy Cooke takes us on a worldwide journey to meet everyone from a Colombian hippo castrator to a Chinese panda porn peddler, all to lay bare the secret--and often hilarious--habits of the animal kingdom. Charming and at times downright weird, this modern bestiary is perfect for anyone who has ever suspected that virtue might be unnatural.

The Adélie Penguin by David Ainley Pdf

The Adélie penguin is one of the best-studied birds in the world and is the subject of research programs from a dozen nations interested in monitoring changes in the environment and the food webs of the Southern Ocean. This species' population has been changing dramatically over the past few decades coincident with a general warming of the maritime portion of Antarctica. When the sea-ice is seen to decline so does the population of Adélie penguins. Further south, however, the population is increasing. This book summarizes our present ecological knowledge of this polar seabird. In so doing, David Ainley describes the ecological factors important to its life history and details the mechanisms by which it is responding to climate change. The author also chronicles the history of research on Adélie penguins, beginning with the heroic expeditions at the beginning of the twentieth century. Weaving together history, ecology, natural history, and written accounts from the earliest Antarctic naturalists into a fascinating account of this charismatic bird, The Adélie Penguin provides a foundation upon which future ornithological research and environmental monitoring can be based. It is a model for investigations into the effect of climate change on a particular species. The book also contains many fine illustrations from the accomplished illustrator Lucia deLeiris and photographs by the author.

Why Penguins Communicate by Pierre Jouventin,F.Stephen Dobson Pdf

Why Penguins Communicate: The Evolution of Visual and Vocal Signals is a comprehensive and condensed review of several hundred publications on the evolution of penguin behaviors, particularly signaling, linking genetics and ecology via such behavioral adaptations as nuptial displays. This exciting work has developed from the authors’ many years researching on the behavioral strategies of penguins, such as the unique vocal signatures for individual recognition. Studies of penguins on islands surrounding Antarctica are presented, fully showcasing the behavioral significance of visual ornaments (mating displays) and how and why penguins behave via adaptive evolutionary explanations. Through this evolutionary lens, the authors address several questions involving their identification and taxonomy, habitat and location, breeding, and differences between penguins and other seabirds. Each species occupies a unique ecological niche, and behaviors permit separating the species through mutual display. Although model organisms in science are diverse and specialized, we see the entire integration in penguins, from acoustical and optical physics, to behavioral display and speciation. This work highlights the adaptive significance of their behavior through an evolutionary point- of-view. Provides a focused view on visual and vocal communication behavior, also presenting the family of penguins as a model for acoustical studies Considers the role of ecological and social environments on the evolution of communication in penguins Spans the gap between the scientific community and an interested lay audience, featuring a readable style for students, professional researchers in biology, ornithologists, ethologists and penguin enthusiasts alike Ideal resource for graduate seminar courses on evolution of behavior, marine ecology, polar biology and ornithology

The Aquatic World of Penguins by David G Ainley,Rory P Wilson Pdf

Centuries ago, when penguins were first encountered by European explorers, they were not thought to be birds but rather a fish-like relative. Subsequent accumulation of knowledge has shown penguins to be an avian species with unrivaled aquatic attributes, owing to a number of evolutionary adaptations: shape change, low drag, ability to regulate buoyancy, and extraordinary surface compliancy from their featheration. They are indeed the most extremely specialized diving bird, having given up flight (which otherwise is hugely advantageous) to the benefit of underwater prowess (such as speed, maneuverability and an ability to exploit an extraordinary range of depths). This flightlessness, however, also comes with costs that are substantial for a seabird (such as the inability to cover large distances quickly in reaction to ephemeral prey); and the energy needed to cope with moving through an aqueous environment, which is more resistant than air. For penguins, the high energetic costs in exploiting the ocean environment thus makes them especially sensitive to changes in food availability or their access to their prey. While a number of “penguin books” cover the natural history, mainly of breeding aspects, few address in much detail the incredible aquatic nature of these creatures. A huge amount of information has been amassed over recent past decades thanks to dramatic advances in microelectronics, bio-logging and maturation of some long-term studies of penguin life history. This work represents an integration of all these data with charts, maps and graphs, along with richly illustrated photos by experts in the field.

Professor Penguin by Lloyd Spencer Davis Pdf

Meet ‘Bill Bryson in Antarctica’ in this engaging book by one of the world's authority on penguins. Part memoir, partly the research of a field biologist, Professor Penguin could be called ‘How Penguins Shaped My Life’. Based on journals kept during Davis’s years of working with penguins in the wild, the story takes readers to remote locations: Antarctica, the Galapagos, the deserts of Chile and Peru, the Falkland Islands, the wild coasts of Argentina and South Africa, and New Zealand. Davis, a world authority on penguins, reveals that these box-office favourites are not the cute ‘mate for life’ animals we’ve been led to believe. He also reveals that penguins are a lot like humans — sometimes disturbingly so — when it comes to their basic needs: sex, food, shelter, marriage, family and travel. Over the years that Davis studies penguins, he realises that they are far more complex and nuanced than he imagines at his first encounter. 'They really don’t deserve to be seen as so black and white.’ He expertly marries scientific knowledge with his own anecdotes — told with humour, hard-earned knowledge and insight. He also includes stories about those who have helped advance our knowledge of penguins —other 'Professor Penguins'. Implicit throughout is Davis’s philosophy – the more we learn about the natural world, and specifically penguins, the more we learn about ourselves. And he asks: Is the isolation of Antarctica sufficient to protect penguins from us?

Antarctic Bird Studies by Oliver L. Austin, Jr. Pdf

Published by the American Geophysical Union as part of the Antarctic Research Series, Volume 12. The birds of Antarctica, and particularly the penguins, have aroused man's interest and his scientific curiosity ever since he first learned of their existence less than two centuries ago. Yet scientific study of them has until recently been only a minor objective of the various expeditions that have visited this most recently discovered and still the least known and least accessible of the continents. The antarctic explorers of the 19th century regarded the birds essentially as a potential source of easily gathered food for men and sled-dogs—and they so used them well into the 20th century. What few bird data and specimens they brought back they acquired largely fortuitously.

Behavior of Marine Animals by Joanna Burger,Bori L. Olla,Howard E. Winn Pdf

The maJonty of the chapters in this volume are structured to include a balance between literature review, original data, and synthesis. The research approaches taken by the authors are generallyof two kinds. One centers on the long-term, in-depth study of a single species in which many aspects of its natural history are examined in detail. The other is a comparative one which involves investigating particular questions by examining species or by comparing groups of species that may include taxonomic andjor ecological affinities. Most of the chapters concern obvious aspects of breeding behavior including habitat selection, the effects of age on breeding, communication, mating systems, synchrony of breeding activities, development of behavior, prefledging parental care, and postfledging parental care. Of these topics, many relate directly to the advantages and disadvantages of coloniality-a conspicuous behavior pattern in marine birds. As such, they provide para.picuou for the further study of coloniality and the social behaviorof many other animals. Other important areas of marine bird breeding behavior (such as courtship behavior, antipredator behavior, information transfer) have not been included because of space limitations. Since man's encroachment on the seashore and continental shelf poses certain threats to marine birds, a volume elucidating various aspects of their biology has multiple uses. As weil as being of value to ornithologists, the volume should be useful to managers involved with coastal planning.

The Emperor's Embrace by Jeffrey Masson Pdf

Jeffrey Moussaieff Masson's "marvelous" (Jane Goodall) New York Times bestseller, When Elephants Weep, made us re-evaluate the emotional lives of animals. And in his follow-up New York Times bestseller, Dogs Never Lie About Love, Masson reflected with "intelligence and originality" (Los Angeles Times Sunday Book Review) on the emotional world of dogs. Now, in The Emperor's Embrace, Masson offers a remarkable look at one of the most fulfilling roles in the animal world: fatherhood. With fascinating insight, impeccable research, and captivating writing, controversial psychoanalyst Jeffrey Masson, a new father himself, introduces us to the world's best dads. He takes us to such places as Antarctica, as he explores how emperor penguin fathers incubate the eggs of their young by carrying them around on their feet for two months, nestled beneath a special brood pouch. And he tells us how, once the babies hatch, the fathers snuggle the babies on their feet until the mother returns from her time at sea, feeding them a special milk-like substance until her arrival. Masson, a superb storyteller, showcases the extraordinary behavior of outstanding fathers, heroes among animals, including: *the wolf -- and why wolves make good fathers and dogs don't *the beaver, who encourages his young to cling to his tail as he navigates through ponds *the sea horse, the only male animal that gives birth to its young *the marmoset, the South American monkey who carries his babies for the first two years of their lives wherever he goes. Masson also examines nature's worst fathers: lions, langurs, bears -- and humans. He shows that when a father does care for his young, as with the beaver, we immediately look for a biological and not an emotional explanation. But Masson demonstrates that for these animals, as with humans, fatherhood is a profound, all-encompassing experience. Groundbreaking, compelling, inspirational, Masson's unique look at one of nature's most venerable institutions takes us to animal habitats around the world, yet always returns to the heart. For animal lovers, fathers, mothers, sons, and daughters everywhere, The Emperor's Embrace is a book that will forever change our perceptions of parenthood and family love.
