Seksueel gedrag is complex én boeiend. Slakken beschieten elkaar bijvoorbeeld met pijlen tijdens hun liefdesspel. Vrouwelijke pimpelmezen gaan graag vreemd, naakte molratten mogen zich niet voortplanten en Amazone-gifkikkers doen aan kinderkannibalisme. Het penisduel vertelt hoe dit kleurrijke gedrag ontstaat. Het blijkt dat alle partijen - mannetje, vrouwtje, jongen en soms ook verwanten - elk hun eigen belangen hebben. Die belangen kunnen overeenkomen, maar soms ook lijnrecht tegenover elkaar staan. Het penisduel bevat concrete verhalen over actueel onderzoek. De onderzoekers komen zelf aan het woord. Ze vertellen bijvoorbeeld over veroveringsstrategieën, partnerkeus, zorg voor jongen, taakverdeling in sociale groepen en de speciale positie van dieren die man en vrouw tegelijk zijn. Naast alledaagse soorten, zoals tuinslakken, wespen en huismussen, passeren ook exotische soorten de revue, zoals blauwpootgenten en reuzenpijlinktvissen. Onooglijke kriebelbeestjes zoals bedwantsen en mieren ontbreken evenmin. Het resultaat is een rijke selectie aan verhalen over het seksuele leven van dieren. Het penisduel is een fascinerend boek voor iedereen die meer wil weten over wat zich afspeelt in de achtertuin, buiten in de natuur, op de kinderboerderij of in de diepzee.

After his famous visit to the Galápagos Islands, Darwin speculated that "one might fancy that, from an original paucity of birds in this archipelago, one species had been taken and modified for different ends." This book is the classic account of how much we have since learned about the evolution of these remarkable birds. Based upon over a decade's research, Grant shows how interspecific competition and natural selection act strongly enough on contemporary populations to produce observable and measurable evolutionary change. In this new edition, Grant outlines new discoveries made in the thirteen years since the book's publication. Ecology and Evolution of Darwin's Finches is an extraordinary account of evolution in action.Originally published in 1986.The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Male primates, carnivores and rodents sometimes kill infants that they did not sire. Infanticide by males is a relatively common phenomenon in these groups, but tends to be rare in any given species. Is this behavior pathological or accidental, or does it reflect a conditional reproductive strategy for males in certain circumstances? In this book, case studies and reviews confirm the adaptive nature of infanticide in males in primates, and help to predict which species should be vulnerable to it. Much of the book is devoted to exploring the evolutionary consequences of the threat of infanticide by males for social and reproductive behavior and physiology. Written for graduate students and researchers in animal behavior, behavioral ecology, biological anthropology and social psychology, this book shows that social systems are shaped not only by ecological pressures, but also social pressures such as infanticide risk.

This book meets the demand for a comprehensive introduction to understanding the processes of population limitation. Recognized world-wide as a respected biologist and communicator, Dr. Ian Newton has now written a clear and detailed treatise on local scale population limiting factors in birds. It is based almost entirely on results from field studies, though it is set in a contemporary theoretical framework. The 16 chapters fall under three major section headings: Behavior and Density Regulation; Natural Limiting Factors; and Human Impacts. Population Limitation in Birds serves as a ne

With an emphasis on the disease conditions of dogs, cats, horses, swine, cattle and small ruminants, Jubb, Kennedy, and Palmer's Pathology of Domestic Animals, 6th Edition continues its long tradition of being the most comprehensive reference book on common domestic mammal pathology. Using a body systems approach, veterinary pathology experts provide overviews of general system characteristics, reactions to insult, and disease conditions that are broken down by type of infectious or toxic insult affecting the anatomical subdivisions of each body system. The sixth edition now boasts a new full-color design, including more than 2,000 high-resolution images of normal and abnormal organs, tissues, and cells. Updated content also includes evolved coverage of disease agents such as the Schmallenberg virus, porcine epidemic diarrhea virus, and the porcine deltacoronavirus; plus new information on molecular-based testing, including polymerase chain reaction (PCR) and in-situ hybridization, keep you abreast of the latest diagnostic capabilities.

Advances in Poultry Welfare provides a targeted overview of contemporary developments in poultry welfare. The reviews in the volume address topical issues related to poultry welfare research and assessment, with a focus on identifying practical strategies for improvement as well as information gaps that remain to be filled. Part One provides an introduction to poultry production systems and gives a broad overview of current poultry welfare issues. Part Two moves on to review several aspects of poultry management, focusing on hatchery practices, early rearing, and slaughter. Part Three deals with welfare assessment on the farm, while Part Four explores continuing challenges, such as feather pecking and skeletal problems. This is followed in Part Five by a discussion of emerging issues, with chapters covering alternative parasite control methods, backyard poultry production, mass depopulation, and genetic approaches to reducing the impact of environmental stressors on welfare. This book is an essential part of the wider ranging series Advances in Farm Animal Welfare, with coverage of cattle, sheep, pigs, and poultry. With its expert editor and international team of contributors, Advances in Poultry Welfare is a key reference tool for welfare research scientists and students, veterinarians involved in welfare assessment, and indeed anyone with a professional interest in the welfare of poultry.--

This book draws together, for the first time, the published research on the behaviour, ecology and welfare of elephants living in zoos, circuses, logging camps and other captive environments in a single comprehensive volume. It takes a multi-disciplinary approach, considering the work of zoo biologists, animal behaviour and welfare scientists, veterinarians, philosophers, zoo educators, tourism specialists, conservation biologists, lawyers and others with a professional interest in elephants. Elephants under Human Care: The Behaviour, Ecology, and Welfare of Elephants in Captivity is a valuable resource for zoo biology and animal welfare researchers. It is also useful for students and zoo professionals and managers looking for a comprehensive guide to current research on captive elephants. Although not intended as a husbandry manual, the book discusses some of the elephant welfare standards developed by the Association of Zoos and Aquariums (AZA) and the British and Irish Association of Zoos and Aquariums (BIAZA) and their relationship to current knowledge of captive elephants. --
