This account of the current state of foraging theory is also a valuable description of the use of optimality theory in behavioral ecology in general. Organizing and introducing the main research ...themes in economic analyses of animal feeding behavior, the authors analyze the empirical evidence bearing on foraging models and answer criticisms of optimality modeling. They explain the rationale for applying optimality models to the strategies and mechanics of foraging and present the basic "average-rate maximizing" models and their extensions. The work discusses new directions in foraging research: incorporating incomplete information and risk-sensitive behavior in foraging models; analyzing trade-offs, such as nutrient requirements and the threat of being eaten while foraging; formulating dynamic models; and building constrained optimization models that assume that foragers can use only simple "rules of thumb." As an analysis of these and earlier research developments and as a contribution to debates about the role of theory in evolutionary biology. Foraging Theory will appeal to a wide range of readers, from students to research professionals, in behavioral ecology, population and community ecology, animal behavior, and animal psychology, and especially to those planning empirical tests of foraging models.
Animal rights activists today regularly use visual imagery in their efforts to shape the public’s understanding of what it means to be “kind,” “cruel,” and ...“inhumane” toward animals. Art for Animals explores the early history of this form of advocacy through the images and the people who harnessed their power.
Following in the footsteps of earlier-formed organizations like the RSPCA and ASPCA, animal advocacy groups such as the Victoria Street Society for the Protection of Animals from Vivisection made significant use of visual art in literature and campaign materials. But, enabled by new and improved technologies and techniques, they took the imagery much further than their predecessors did, turning toward vivid, pointed, and at times graphic depictions of human-animal interactions. Keri Cronin explains why the activist community embraced this approach, details how the use of such tools played a critical role in educational and reform movements in the United States, Canada, and England, and traces their impact in public and private spaces. Far from being peripheral illustrations of points articulated in written texts or argued in impassioned speeches, these photographs, prints, paintings, exhibitions, “magic lantern” slides, and films were key components of animal advocacy at the time, both educating the general public and creating a sense of shared identity among the reformers.
Uniquely focused on imagery from the early days of the animal rights movement and filled with striking visuals, Art for Animals sheds new light on the history and development of modern animal advocacy.
This open access book summarizes the multi-disciplinary results of one of China’s main primatological research projects on the endemic Tibetan macaque (Macaca thibetana), which had continued for over ...30 years, but which had never been reported on systematically. Dedicated to this exceptional Old World monkey, this book makes the work of Chinese primatologists on the social behavior, cooperation, culture, cognition, group dynamics, and emerging technologies in primate research accessible to the international scientific community. One of the most impressive Asian monkeys, and the largest member of its genus, the Tibetan macaque deserves to be better known. This volume goes a long way towards bringing this species into the spotlight with many excellent behavioral analyses from the field. - Frans de Waal, Professor of Psychology, Emory University, USA. Macaques matter. To understand primate patterns and trends, and to gain important insight into humanity, we need to augment and expand our engagement with the most successful and widespread primate genus aside from Homo. This volume focuses on the Tibetan macaque, a fascinating species with much to tell us about social behavior, physiology, complexity and the macaque knack for interfacing with humans. This book is doubly important for primatology in that beyond containing core information on this macaque species, it also reflects an effective integrated collaboration between Chinese scholars and a range of international colleagues—exactly the type of collaborative engagement primatology needs. This volume is a critical contribution to a global primatology. - Agustín Fuentes, Professor of Anthropology, University of Notre Dame, USA. I have many fond memories of my association with Mt. Huangshan research beginning in 1983, when together with Professor Qishan Wang we established this site. It is such a beautiful place and I miss it. It is gratifying to see how far research has progressed since we began work there, becoming more internationalized and very much a collaborative endeavor under the long-term direction of Professor Jin-Hua Li and colleagues. This book highlights the increased interest in this species, representing a variety of disciplines ranging from macro aspects of behavior, cognition and sociality, to micro aspects of microbes, parasites and disease, authored by a group of renowned Chinese and international primatologists. I applaud their efforts and expect more interesting work to come from this site in the years ahead. - Kazuo Wada, Professor Emeritus, Kyoto University, Japan.

This book argues that we are obligated to treat all sentient animals as “ends in themselves.” Drawing on a theory of the good derived from Aristotle, it offers an explanation of why animals are the ...sorts of beings who have a good. Drawing on a revised version of Kant’s argument for the value of humanity, it argues that rationality commits us to claiming the standing of ends in ourselves in two senses. As autonomous beings, we claim to be ends in ourselves when we claim the standing to make laws for ourselves and each other. As beings who have a good, we also claim to be ends in ourselves when we take the things that are good for us to be good absolutely and so worthy of pursuit. The first claim commits us to joining with other autonomous beings in relations of reciprocal moral lawmaking. The second claim commits us to treating the good of every sentient animal as something of absolute importance. The book also argues that human beings are not more important than, superior to, or better off than the other animals. It criticizes the “marginal cases” argument and advances a view of moral standing as attaching to the atemporal subjects of lives. It offers a non-utilitarian account of the relationship between the good and pleasure, and addresses questions about the badness of extinction and about whether we have the right to eat animals, experiment on them, make them work for us, and keep them as pets.
Understanding the relationships between humans and animals is essential to a full understanding of both our present and our shared past. Across the humanities and social sciences, researchers have ...embraced the ‘animal turn,’ a multispecies approach to scholarship, with historians at the forefront of new research in human-animal studies that blends traditional research methods with interdisciplinary theoretical frameworks that decenter humans in historical narratives. These exciting approaches come with core methodological challenges for scholars seeking to better understand the past from non-anthropocentric perspectives. Whether in a large public archive, a small private collection, or the oral histories of living memories, stories of animals are mediated by the humans who have inscribed the records and organized archival collections. In oral histories, the place of animals in the past are further refracted by the frailty of human memory and recollection. Only traces remain for researchers to read and interpret. Bringing together seventeen original essays by a leading group of international scholars, Traces of the Animal Past showcases the innovative methods historians use to unearth and explain how animals fit into our collective histories. Situating the historian within the narrative, bringing transparency to methodological processes, and reflecting on the processes and procedures of current research, this book presents new approaches and new directions for a maturing field of historical inquiry.
Most livestock in America currently live in cramped and unhealthy confinement, have few stable social relationships with humans or others of their species, and finish their lives by being transported ...and killed under stressful conditions. InLivestock, Erin McKenna allows us to see this situation and presents alternatives. She interweaves stories from visits to farms, interviews with producers and activists, and other rich material about the current condition of livestock. In addition, she mixes her account with pragmatist and ecofeminist theorizing about animals, drawing in particular on John Dewey's account of evolutionary history, and provides substantial historical background about individual species and about human-animal relations.
This deeply informative text reveals that the animals we commonly see as livestock have rich evolutionary histories, species-specific behaviors, breed tendencies, and individual variation, just as those we respect in companion animals such as dogs, cats, and horses. To restore a similar level of respect for livestock, McKenna examines ways we can balance the needs of our livestock animals with the environmental and social impacts of raising them, and she investigates new possibilities for human ways of being in relationships with animals. This book thus offers us a picture of healthier, more respectful relationships with livestock.
This book describes a powerful and flexible technique for the modeling of behavior, based on evolutionary principles. The technique employs stochastic dynamic programming and permits the analysis of ...behavioral adaptations wherein organisms respond to changes in their environment and in their own current physiological state. Models can be constructed to reflect sequential decisions concerned simultaneously with foraging, reproduction, predator avoidance, and other activities. The authors show how to construct and use dynamic behavioral models. Part I covers the mathematical background and computer programming, and then uses a paradigm of foraging under risk of predation to exemplify the general modeling technique. Part II consists of five "applied" chapters illustrating the scope of the dynamic modeling approach. They treat hunting behavior in lions, reproduction in insects, migrations of aquatic organisms, clutch size and parental care in birds, and movement of spiders and raptors. Advanced topics, including the study of dynamic evolutionarily stable strategies, are discussed in Part III.
LOL cats. Grumpy Cat. Dog-rating Twitter. Pet Instagram accounts. It’s generally understood the internet is for pictures of cute cats (and dogs, and otters, and pandas). But what motivates people to ...make and share these images, and how do they relate to other online social practices?
The Internet is for Cats examines how animal images are employed to create a lighter, more playful mood, uniting users within online spaces that can otherwise easily become fractious and toxic. Placing today’s pet videos, photos, and memes within a longer history of mediated animal images, communication scholar Jessica Maddox also considers the factors that make them unique. She explores the roles that animals play within online economies of cuteness and attention, as well as the ways that animal memes and videos respond to common experiences of life under neoliberalism.
Conducting a rich digital ethnography, Maddox combines observations and textual analysis with extensive interviews of the people who create, post and share animal media, including TikTok influencers seeking to make their pets famous, activists tweeting about wildlife conservation, and Redditors upvoting every cute cat photo. The Internet is for Cats will leave you with a new appreciation for the human social practices behind the animal images you encounter online.
Psychiatrists define cruelty to animals as a psychological problem or personality disorder. Legally, animal cruelty is described by a list of behaviors. In Just a Dog, Arnold Arluke argues that our ...current constructs of animal cruelty are decontextualized—imposed without regard to the experience of the groups committing the act. Yet those who engage in animal cruelty have their own understandings of their actions and of themselves as actors. In this fascinating book, Arluke probes those understandings and reveals the surprising complexities of our relationships with animals. Just a Dog draws from interviews with more than 250 people, including humane agents who enforce cruelty laws, college students who tell stories of childhood abuse of animals, hoarders who chronically neglect the welfare of many animals, shelter workers who cope with the ethics of euthanizing animals, and public relations experts who use incidents of animal cruelty for fundraising purposes.
