""How many creatures walking on this earth / Have their first being in another form?" the Roman poet Ovid asked two thousand years ago. He could not have known the full extent of the truth: Today, biologists estimate a stunning three-quarters of all animal species on earth undergo some form of metamorphosis. But why do tadpoles transform into frogs, caterpillars into butterflies, elvers into eels, immortal jellyfish from sea sprigs to medusae and back again, growing younger and younger in frigid ocean depths? Why must creatures go through massive destruction and remodeling to become who they are? Tracing a path from Aristotle--who rejected the possibility of metamorphosis--to Darwin to today, historian of science Oren Harman explores that central mystery. Metamorphosis, however, isn't just a biological puzzle: It takes us to the very heart of questions of being and identity, whatever kind of change we may undergo. Metamorphosis is a new classic of natural history: a book that, by unveiling a mystery of nature, causes us to relearn ourselves"--Publisher's description.

One of The New York Times Critics' Picks of the Year From acclaimed psychoanalyst Adam Phillips, a meditation on what we must give up to feel more alive. To give up or not to give up? The question can feel inescapable but the answer is never simple. Giving up our supposed vices is one thing; giving up on life itself is quite another. One form of self-sacrifice feels positive, something to admire and aspire to, while the other is profoundly unsettling, if not actively undesirable. There are always, it turns out, both good and bad sacrifices, but it is not always clear beforehand which is which. We give something up because we believe we can no longer go on as we are. In this sense, giving up is a critical moment—an attempt to make a different future. In On Giving Up , the acclaimed psychoanalyst Adam Phillips illuminates both the gaps and the connections between the many ways of giving up and helps us to address the central question: What must we give up in order to feel more alive?

Excerpt from A Statistical Study of the Rattlesnakes It is well known that the active fangs of the rat tlesnakes are changed or replaced periodically, such renewal occurring whether the discarded member has been damaged or is still intact. Whether replacement is hastened, if a functional fang has been broken out entirely, prior to the normal time of change, is not known. The delicacy and fra gility of the fangs, particularly in the smaller snakes, makes such a provision for replacement imperative, as does likewise the necessity for providing larger fangs as a snake grows.

A collection of essays and transcripts of interviews and speeches by Earth First!er Judi Bari who survived first a 1990 car-bombing that left her paralyzed, then subsequent implication in her own attack, in spite of clear motives and death-threats from others. These articles and essays provide a history of Earth First!'s work and internal struggles, the involvement of the timber corporations, Richard Held (of COINTELPRO fame) and the FBI in discrediting Earth First!, as well as Bari's own complex relationship with the organization and some of its tactics.

Abundant fish along North America's West Coast Coast have nurtured rich and diverse cultures for centuries. But today millions of sockeye salmon routinely seem to disappear from the Fraser River, chinook salmon populations are collapsing, the abalone fishery is one of several that has been shut down and oolichan populations are in dramatic decline. At the same time, biodiversity is being lost as the remaining stocks are concentrated into fewer populations. Will the Pacific fishery go the way of the Atlantic fishery? How can it be better managed? And what can be done to ensure its long-term sustainability? In Dead Reckoning, award-winning journalist Terry Glavin attempts to answer these troublesome questions. He begins at Byrne Creek, a local stream that shaped his boyhood world, then takes us up the Fraser River, where Coyote once assigned fishing rights and techniques, and out onto the high seas. It is later than we think - but not too late, says Glavin. In precise, highly visual and moving prose, he presents concrete alternatives for fishing communities on the West Coast and around the globe, and introduces us to some of the fishers, biologists and average citizens who are working to conserve and restore the world's great fisheries today.

Research on bacterial adhesion and its significance is a major field involving many different aspects of nature and human life, such as marine science, soil and plant ecology, most importantly, the biomedical field. The adhesion ofbacteria to the food industry, and human tissue surfaces and implanted biomaterial surfaces is an important step in the patho genesis of infection. Handbook 0/ Bacterial Adhesion: Principles, Methods, and Applications is an outgrowth of the editors' own quest for information on laboratory techniques for studying bacte rial adhesion to biomaterials, bone, and other tissues and, more importantly, a response to significant needs in the research community. This book is designed to be an experimental guide for biomedical scientists, biomaterials scientists, students, laboratory technicians, or anyone who plans to conduct bacterial adhesion studies. More specifically, it is intended for all those researchers facing the chal lenge of implant infections in such devices as orthopedic prostheses, cardiovascular devices or catheters, cerebrospinal fluid shunts or extradural catheters, thoracic or abdominal catheters, portosystemic shunts or bile stents, urological catheters or stents, plastic surgical implants, oral or maxillofacial implants, contraceptive implants, or even contact lenses. It also covers research methods for the study of bacterial adhesion to tis sues such as teeth, respiratory mucosa, intestinal mucosa, and the urinary tract. In short, it constitutes a handbook for biomechanical and bioengineering researchers and students at all levels.

Originally published in 1926, this book describes the varieties of potato prevalent in the UK in the early twentieth century. Salaman also examines the environmental and genetic forces 'which control the production of these varieties, their behaviour and their ultimate destiny'. Several plates illustrating points of variety, such as leaves and flowers, are also provided. This book will be of value to anyone with an interest in the history of the potato in the UK.

Recipient of the ECI Prize in 1993 for terrestrial ecology. Reviews and analyses the essential aspects of modern ecological research and its bearing on society and on related sciences. The author deplores that many ecologists are not doing enough to motivate society into counteracting the increasing degradation of our environment. Hence, he outlines and discusses what, in his opinion, research ecologists should do to avoid the world's plunge towards ecocatastrophe.

This unique book is the first of its kind to explore the diversity of interactions between insects and birds. A group of international experts enthusiastically agreed to contribute to the four sections of the book following the success of an Entomological Club Conference on Insect and Bird Interactions. The first section covers population management issues, discussing effects on birds highly relevant to the planting of large areas of GM crops, new opportunities for increasing biodiversity in farming landscapes, and the novel aspect of managing insects by exploiting birds as biological control agents. This is followed by a section discussing the effects of insecticides on bird populations, and includes a contribution from the RSPB, as well as a re-appraisal of the effects of DDT on raptors. Next, the foraging behaviour of birds on insects is discussed, with chapters also on ‘warning’ coloration in insects and learning by birds. The first chapter in this section is unusual in having been written by an ophthalmologist and covers colour vision in birds, more specifically ultraviolet vision in relation to insect coloration. Finally, the authors look at insects that are parasites of birds or feed on the detritus in nests, and review the ecology and evolution of the co-adaptation of insect ectoparasites with birds. Insect and Bird Interactions is unparalleled in scope and coverage and will be of interest to entomologists, ornithologists, and ecologists alike.

In this remarkable book by one of the great psychologists and neurologists of the early twentieth century, Kurt Goldstein presents a summation of his “holistic” theory of the human organism. In the course of his studies on brain-damaged soldiers during the First World War, Goldstein became aware of the failure of contemporary biology and medicine to genuinely understand both the impact of such injuries and the astonishing adjustments that patients made to them. He challenged reductivist approaches that dealt with “localized” symptoms, insisting instead that an organism be analyzed in terms of the totality of its behavior and interaction with its surrounding milieu. He was especially concerned with the breakdown of organization and the failure of central cerebral controls that take place in catastrophic responses to situations such as physical or mental illness. But Goldstein was equally attuned to the amazing powers of the organism to readjust to such devastating losses, if only by withdrawal to a more limited range of activity that it could manage by a redistribution of its reduced energies, thus reclaiming as much wholeness as new circumstances allowed. Goldstein’s concepts in The Organism have had a major impact on philosophical and psychological thought throughout this century, as can be seen in the work of Maurice Merleau-Ponty, Georges Canguilhem, Ernst Cassirer, Ludwig Binswanger, and Roman Jakobson, not to mention the wide-ranging field of Gestalt psychology.
