Animal Cognition, Kristin Andrews, Ljiljana Radenovic Apr 2015

Animal Cognition, Kristin Andrews, Ljiljana Radenovic

Kristin Andrews, PhD

Debates in applied ethics about the proper treatment of animals often refer to empirical data about animal cognition, emotion, and behavior. In addition, there is increasing interest in the question of whether any nonhuman animal could be something like a moral agent.


Chimpanzee Theory Of Mind: Looking In All The Wrong Places?, Kristin Andrews Apr 2015

Chimpanzee Theory Of Mind: Looking In All The Wrong Places?, Kristin Andrews

Kristin Andrews, PhD

I respond to an argument presented by Daniel Povinelli and Jennifer Vonk that the current generation of experiments on chimpanzee theory of mind cannot decide whether chimpanzees have the ability to reason about mental states. I argue that Povinelli and Vonk’s proposed experiment is subject to their own criticisms and that there should be a more radical shift away from experiments that ask subjects to predict behavior. Further, I argue that Povinelli and Vonk’s theoretical commitments should lead them to accept this new approach, and that experiments which offer subjects the opportunity to look for explanations for anomalous behavior should …


A Role For Folk Psychology In Animal Cognition Research, Kristin Andrews Apr 2015

A Role For Folk Psychology In Animal Cognition Research, Kristin Andrews

Kristin Andrews, PhD

If we consider that the field of animal cognition research began with Darwin’s stories about clever animals, we can see that over the 150 years of work done in this field, there has been a slow swing back and forth between two extreme positions. One extreme is the view that other animals are very much like us, that we can use introspection in order to understand why other animals act as they do, and that no huge interpretive leap is required to understand animal minds. On the other extreme we have the view that other animals are utterly different from …


Empathy In Other Apes, Kristin Andrews, Lori Gruen Apr 2015

Empathy In Other Apes, Kristin Andrews, Lori Gruen

Kristin Andrews, PhD

A number of scholars have offered behavioral and physiological arguments in favor of the existence of empathy in other species (see Bekoff & Pierce 2009, Flack & de Waal 2000, Plutchik 1987). While the evidence is compelling, claims about empathy in nonhuman apes face two different challenges. The first challenge comes from a set of empirical findings that suggest great apes are not able to think about other’s beliefs. The argument here is based on a view that empathy is associated with folk psychological understanding of others’ mental states, or mindreading, and the existence of mindreading among the other apes …


Do Zoos And Aquariums Promote Attitude Change In Visitors? A Critical Evaluation Of The American Zoo And Aquarium Study, Lori Marino, Scott O. Lilienfeld, Randy Malamud, Nathan Nobis, Ron Broglio Mar 2015

Do Zoos And Aquariums Promote Attitude Change In Visitors? A Critical Evaluation Of The American Zoo And Aquarium Study, Lori Marino, Scott O. Lilienfeld, Randy Malamud, Nathan Nobis, Ron Broglio

Nathan M. Nobis, PhD

Modern-day zoos and aquariums market themselves as places of education and conservation. A recent study conducted by the American Zoo and Aquarium Association (AZA) (Falk et al., 2007) is being widely heralded as the first direct evidence that visits to zoos and aquariums produce long-term positive effects on people’s attitudes toward other animals. In this paper, we address whether this conclusion is warranted by analyzing the study’s methodological soundness. We conclude that Falk et al. (2007) contains at least six major threats to methodological validity that undermine the authors’ conclusions. There remains no compelling evidence for the claim that zoos …


The “Babe” Vegetarians: Bioethics, Animal Minds And Moral Methodology, Nathan Nobis Mar 2015

The “Babe” Vegetarians: Bioethics, Animal Minds And Moral Methodology, Nathan Nobis

Nathan M. Nobis, PhD

Here I discuss the role the film “Babe” has played in helping people address these challenges and make this moral progress. It is thought that a significant number of young people (mostly girls, now young women) became vegetarians due to their seeing “Babe.” These people are often called “Babe Vegetarians,” influence by what has been called “The Babe Effect.” Many of their stories are found on the internet.


The Ethics Of Wildlife Control In Humanized Landscapes, John Hadidian, Camilla H. Fox, William S. Lynn Mar 2015

The Ethics Of Wildlife Control In Humanized Landscapes, John Hadidian, Camilla H. Fox, William S. Lynn

John Hadidian, PhD

The 21st century is witness to an unprecedented and rapid growth of human settlements, from urban centers to wilderness vacation resorts. Concurrent with this has been the growing tolerance and acceptance of many wild animals and humans for one another. This has created an expanding ‘zone’ of human-animal contacts, some number of which invariably result in conflicts. While the vast majority of our interactions with wild animals are undoubtedly benign, it is the conflict between wildlife and people that draws particularly close attention from the public. Animals viewed as vertebrate “pests” range from the small to the large, the timid …


Resolving Animal Distress And Pain: Principles And Examples Of Good Practice In Various Fields Of Research, Alicia Karas, Matthew C. Leach, Karl A. Andrutis, Kathleen Conlee, John P. Gluck, Andrew N. Rowan, Martin L. Stephens Mar 2015

Resolving Animal Distress And Pain: Principles And Examples Of Good Practice In Various Fields Of Research, Alicia Karas, Matthew C. Leach, Karl A. Andrutis, Kathleen Conlee, John P. Gluck, Andrew N. Rowan, Martin L. Stephens

Andrew N. Rowan, DPhil

Pain and distress are central topics in legislation, regulations, and standards regarding the use of animals in research. However, in practice, pain has received greatly increased attention in recent years, while attention to distress has lagged far behind, especially for distress that is not induced by pain. A contributing factor is that there is less information readily available on distress, including practical information on its recognition, assessment and alleviation.

This chapter attempts to help fill that void by reversing the usual pattern and giving greater attention to distress than to pain. In addition, we also bypass the pain versus distress …


Integrated Pest Management (Ipm) For Vertebrates: Do We Need To Broaden This Concept?, John Hadidian Mar 2015

Integrated Pest Management (Ipm) For Vertebrates: Do We Need To Broaden This Concept?, John Hadidian

John Hadidian, PhD

The concepts and practices of Integrated Pest Management (IPM) are historically grounded in programs aimed at insects and disease-causing organisms affecting agriculture. When applied to vertebrates, IPM concepts have most often been used in rodent control programs. Still, IPM is a powerful model that arguably can, and should, apply to conflicts with any “pest” or problem-causing organism. It may be time to examine contemporary IPM approaches and their relation to traditional vertebrate pest control more closely. Vertebrate IPM should encompass not only the development of sound and practical steps to shape decision-making and actions, but a dialogue about ethics as …

Optimizing Conservation Strategies For Mexican Free-Tailed Bats: A Population Viability And Ecosystem Services Approach, Ruscena Wiederholt, Laura López-Hoffman, Colleen Svancara, Gary Mccracken, Wayne Thogmartin, Jay E. Diffendorfer, Brady Mattson, Kenneth Bagstad, Paul Cryan, Amy L. Russell, Darius Semmens, Rodrigo A. Medellín

Amy L. Russell

Conservation planning can be challenging due to the need to balance biological concerns about population viability with social concerns about the benefits biodiversity provide to society, often while operating under a limited budget. Methods and tools that help prioritize conservation actions are critical for the management of at-risk species. Here, we use a multi-attribute utility function to assess the optimal maternity roosts to conserve for maintaining the population viability and the ecosystem services of a single species, the Mexican free-tailed bat (Tadarida brasiliensis mexicana). Mexican free-tailed bats provide ecosystem services such as insect pest-suppression in agricultural areas and recreational viewing …


An Assessment Of South China Tiger Reintroduction Potential In Hupingshan And Houhe National Nature Reserves, China, Yiyuan Qin, Philip J. Nyhus, Courtney L. Larson, Charles J.W. Carroll, Jeff Muntifering, Thomas D. Dahmer, Lu Jun, Ronald L. Tilson Dec 2014

An Assessment Of South China Tiger Reintroduction Potential In Hupingshan And Houhe National Nature Reserves, China, Yiyuan Qin, Philip J. Nyhus, Courtney L. Larson, Charles J.W. Carroll, Jeff Muntifering, Thomas D. Dahmer, Lu Jun, Ronald L. Tilson

Philip J. Nyhus

Human-caused biodiversity loss is a global problem, large carnivores are particularly threatened, and the tiger (Panthera tigris) is among the world’s most endangered large carnivores. The South China tiger (Panthera tigris amoyensis) is the most critically endangered tiger subspecies and is considered functionally extinct in the wild. The government of China has expressed its intent to reintroduce a small population of South China tigers into a portion of their historic range as part of a larger goal to recover wild tiger populations in China. This would be the world’s first major tiger reintroduction program. A free-ranging population of 15–20 tigers …
