To Preserve Or To Conserve?, Liv Baker Jan 2019

To Preserve Or To Conserve?, Liv Baker

Animal Sentience

Treves et al. propose the notion of trusteeship to help meet our responsibility to nature and individual animals, their homes, cultures, and societies. This proposal is grounded in a real-world framework that reveals how conservation has become distorted by anthropocentrism, human exceptionalism, and ethical hypocrisy.


Just Reductionism: In Defense Of Holistic Conservation, Bradley J. Bergstrom Jan 2019

Just Reductionism: In Defense Of Holistic Conservation, Bradley J. Bergstrom

Animal Sentience

Treves et al. (2019) argue that individual organisms should be protected by the courts. This already happens in many countries for rare and endangered species and for symbolically important species (e.g., raptors, songbirds, and bats in the U.S.), and through the international treaty for whales. But protection of these individuals stems from a focus on preserving their populations, whereas hunting of individuals is still a culturally accepted practice. Killing of individuals should be limited to valid reasons (e.g., eating the meat) and covered by fair-chase and humane-killing laws (which is not always the case). But “futurity” will not inherit present-day …


Just Preservation And The Half-Earth View, Helen Kopnina Jan 2019

Just Preservation And The Half-Earth View, Helen Kopnina

Animal Sentience

For interspecies justice, animal welfare, and animal rights, the planet needs to be divided on the basis of species' natural resource requirements. The Half-Earth View is that to maintain viable populations of the Earth's remaining species, half of landscapes and seascapes need protection from intensive economic activity. This protection is needed outside the nature preserve system, such as in agricultural areas or cities, so nature can co-exist with local communities.


Protecting Patients Who Lack A Voice, Rainer Spiegel Jan 2019

Protecting Patients Who Lack A Voice, Rainer Spiegel

Animal Sentience

Neither human young today nor future human generations nor non-human species have a voice in protecting the biosphere. Treves et al. propose courts and trustees for defending their interests. I describe an analogy with attempts to represent the interests of children and comatose patients in medicine.


Human Interests, Helen Tiffin Jan 2019

Human Interests, Helen Tiffin

Animal Sentience

Treves et al.’s proposal is welcome, but it will have to face at least four challenges: the interconnectedness of the human and the nonhuman portions of the biosphere, conflicts of interest, human overpopulation, and capitalism itself.


The Intrinsic Value Of Nature, Joanna E. Lambert Jan 2019

The Intrinsic Value Of Nature, Joanna E. Lambert

Animal Sentience

Treves et al. explain the need to preserve the rights of nonhuman species, human youth, and future generations. Although conservation biology has claimed to have an intrinsic valuation ethic since its inception in the 1980s, many aspects of the field have taken a decidedly anthropocentric and instrumentalist trajectory. This has important consequences for conservation-related policy and practice at all scales: local, regional, and global.


Developmental Aspects Of Capacities, Karen Bartsch Jan 2019

Developmental Aspects Of Capacities, Karen Bartsch

Animal Sentience

Chapman & Huffman suggest that judgments of human superiority underlie our cruelty to animals. It might be useful to examine how such judgments operate within the human community. Children arguably have a potential for developing “superior” capacities but are outperformed on many tasks by animals. There is a continuum of development in children’s capacities. Perhaps there are interspecies evolutionary continua too. This highlights the complexity of reasoning about humans, animals, and moral inclusion.


Humans: Uniquely Responsible For Causing Conservation Problems, Uniquely Capable Of Solving Them, Michael L. Wilson, Clarence L. Lehman Jan 2019

Humans: Uniquely Responsible For Causing Conservation Problems, Uniquely Capable Of Solving Them, Michael L. Wilson, Clarence L. Lehman

Animal Sentience

We share Chapman & Huffman’s views on the importance of promoting animal welfare and conservation. We disagree with their implication, however, that reverence for life and concern for the wellbeing of global ecosystems depend on a belief that other living things are similar to humans in any of their capacities. Humans exhibit special traits — language, cumulative culture, extraordinary capacity for cooperation when we are at our best, and ever-advancing technological developments — that enabled them to dominate the planet, resulting in the current conservation crisis. It is precisely the fact that humans have become unique that provides hope for …


More Evidence Of Complex Cognition In Nonhuman Species, Lesley J. Rogers Jan 2019

More Evidence Of Complex Cognition In Nonhuman Species, Lesley J. Rogers

Animal Sentience

Chapman & Huffman have highlighted observations of animals performing, in nature, complex behaviour once thought to be unique to humans. Just as relevant to their argument are examples of cognition shown by domesticated species tested in controlled conditions. These strengthen the case for human/nonhuman similarities in behaviour and cognition. Recent research has brought to our attention the ability of nonhuman species to perform many tasks previously considered to be the hallmark of humans. Even though different species may use different ways of solving these tasks, the very fact that they can do it undermines the notion of human superiority.


Unique In Degree Not Kindness, Jennifer Vonk Jan 2019

Unique In Degree Not Kindness, Jennifer Vonk

Animal Sentience

Humans are certainly unique among living species. This is evident in the transformation of human environments and its resulting impact on other animals. However, many of the traits unique to humans are costly as well as adaptive and should certainly not be used to elevate their status above that of other species.


Animal Sentience Is Not Enough To Motivate Conservation, Irene M. Pepperberg Jan 2019

Animal Sentience Is Not Enough To Motivate Conservation, Irene M. Pepperberg

Animal Sentience

Chapman & Huffman suggest that humans’ views of their own superiority are a source of their callousness toward the environment. I do not disagree but point to a number of other issues that must be addressed for conservation efforts to succeed.


Mirror Neurons And Humanity’S Dark Side, Gisela Kaplan Jan 2019

Mirror Neurons And Humanity’S Dark Side, Gisela Kaplan

Animal Sentience

The last two decades have revealed brain mechanisms in birds and primates showing that, contrary to earlier prejudices, some birds can do things (cognitive and affective) on par with or even better than great apes and humans. The old dichotomies are breaking down; but the dark side is that these insights come at a time in the Anthropocene when humans have caused and continue to cause mass extinctions.


Humans May Be Unique And Superior — And That Is Irrelevant, Eze Paez Jan 2019

Humans May Be Unique And Superior — And That Is Irrelevant, Eze Paez

Animal Sentience

Chapman & Huffman argue that, because humans are neither unique nor superior to the other animals, cruelty to animals is not justified. Though I agree with their conclusion, I do not think their argument works. Many human beings do have some capacities that animals do not have and are greater in some respects, in the sense of having superior abilities. It is a better argument to deny that any of that is morally relevant. Sentience suffices for moral consideration, and for deriving a moral duty not to harm other animals and to assist them when they are in need.


Humans Have Always Been Unique!, William C. Mcgrew Jan 2019

Humans Have Always Been Unique!, William C. Mcgrew

Animal Sentience

Arguments about human uniqueness apply not only to extant species but also to extinct ones, that is, the hominin predecessors of anatomically modern Homo sapiens. Thus, unique and superior are doubly relative terms, in past and present. The scope for empirical comparison faces a spectrum of difficulty, from material (e.g., artefacts) to non-material (e.g., concepts) phenomena.


Phooey On Comparisons, Gwen J. Broude Jan 2019

Phooey On Comparisons, Gwen J. Broude

Animal Sentience

Chapman & Huffman reject the notion that human beings are very different from other animals. The goal is to undermine the claim that human uniqueness and even superiority are reason enough to treat other animals badly. But evaluating human uniqueness for this purpose only plays into the hands of those who exploit invidious comparisons between us and other animals to justify mistreatment of the rest of the animal kingdom. What human uniqueness we may discover would still be no justification for how we behave toward other animals. We should also ask ourselves whether any human-centric criterion can be justification for …


Anthropomorphism Is The First Step, Marthe Kiley-Worthington Jan 2019

Anthropomorphism Is The First Step, Marthe Kiley-Worthington

Animal Sentience

Individuals have intentions, beliefs and choices. This sense of “personhood” has been known and used for centuries by those who have dealt professionally with any nonhuman mammal. All mammals have a lot in common physically and mentally. The first step toward understand another species’ point of view is anthropomorphism.


Taking Exception To Human Exceptionalism, Carrie P. Freeman Jan 2019

Taking Exception To Human Exceptionalism, Carrie P. Freeman

Animal Sentience

Chapman & Huffman refute common claims used to justify human species distinctions, and they critique the animal cruelty that has resulted from this privileged status. I raise related questions for further study of the roots of human exceptionalism and about whether aspiring to be more like our fellow animals might be part of the solution.


Phenotypic Similarity And Moral Consideration, S. Brian Hood, Sophia Giddens Jan 2019

Phenotypic Similarity And Moral Consideration, S. Brian Hood, Sophia Giddens

Animal Sentience

Identifying specific traits to justify according differential moral status to humans and non-human animals may be more challenging than Chapman & Huffman suggest. The reasons for this also go against their recommendation that we ought to attend to how humans and non-humans are similar. The problem lies in identifying the moral relevance of biological characteristics. There are, however, other reasons for treating non-human animals as worthy of moral consideration, such as the Precautionary Principle.


Anthropocentrism: Practical Remedies Needed, Helen Kopnina Jan 2019

Anthropocentrism: Practical Remedies Needed, Helen Kopnina

Animal Sentience

It is true that one of the harmful consequences of creating categories where one group is unique and superior to others is that it justifies discriminating against the inferior groups. And outright abuse of nonhuman animals is indeed morally unjustifiable. But what is to be done about it?


Our Brains Make Us Out To Be Unique In Ways We Are Not, Matthew J. Criscione, Julian Paul Keenan Jan 2019

Our Brains Make Us Out To Be Unique In Ways We Are Not, Matthew J. Criscione, Julian Paul Keenan

Animal Sentience

Humans have long viewed themselves in a favorable light. This bias is consistent with a general pattern of self-enhancement. Neural systems in the medial prefrontal cortex underlie this way of thinking, which, even when false, may be beneficial for survival. It is hence not surprising that we often disregard contrary evidence in believing ourselves superior.


Is Human Uniqueness Fake News?, Sean Hermanson Jan 2019

Is Human Uniqueness Fake News?, Sean Hermanson

Animal Sentience

The world and its troubles don't need unfounded denials of human uniqueness.


“I Am Not An Animal”, Lori Marino Jan 2019

“I Am Not An Animal”, Lori Marino

Animal Sentience

The answer to Chapman & Huffman’s question — “Why do we want to think humans are different?” — lies in the work of Ernest Becker and the social psychology literature known as Terror Management Theory, according to which our deep anxiety about animality and death can drive our need to feel superior to the other animals.


Across The Great Divide, Debra Merskin Jan 2019

Across The Great Divide, Debra Merskin

Animal Sentience

Chapman & Huffman’s target article calls for a reevaluation of claims of human uniqueness and superiority. It also adds to the literature on how species differences, as Darwin noted, are more of degree than kind. The threats to environmental health and species survival are a consequence of excluding nonhuman animals from moral concern and consideration. The theory of intersectionality should include speciesism in the array of discriminatory practices.


Corticocentric Bias In Cognitive Neuroscience, Orit Nafcha, Shai Gabay Jan 2019

Corticocentric Bias In Cognitive Neuroscience, Orit Nafcha, Shai Gabay

Animal Sentience

Chapman & Huffman (2018) note that our tendency to categorize leads to a sense of human superiority that helps justify violence against nonhuman animals. Yet animals are turning out to have capacities previously thought to be uniquely human. We add a further factor that may contribute to the false sense of human superiority: the "corticocentric" bias of neuroscience. An evolutionary approach may help identify species similarities and differences, providing a better understanding of the uniqueness of each species.


Taking Darwinism Seriously, Carsta Simon Jan 2019

Taking Darwinism Seriously, Carsta Simon

Animal Sentience

Chapman & Huffman propose that dropping the categorical distinction between human and nonhuman animals may reduce the atrocious acts of humans towards nonhuman animals, but will it? Taking Darwinism seriously means accepting physical and behavioral continuity across species, including the capacity to feel pain.


Refining Thoughts About Human/Nonhuman Differences, Colin A. Chapman, Michael A. Huffman Jan 2019

Refining Thoughts About Human/Nonhuman Differences, Colin A. Chapman, Michael A. Huffman

Animal Sentience

Our commentators come from many fields and disciplines and express highly divergent views, illustrating broad interest in the question. From the breadth of comments, we have identified two recurring themes, which we focus on here. The first is a preponderance of cautionary remarks about evaluating the differences between humans and nonhuman animals. The second concerns whether considering animals as worthy of moral consideration is one of many useful tools for conservationists trying to prevent extinction, habitat destruction, and climate change.


Why Cod Don't Like To Sunbathe: Quantity And Quality In The Animal Kingdom, Christoph Jung Jan 2019

Why Cod Don't Like To Sunbathe: Quantity And Quality In The Animal Kingdom, Christoph Jung

Animal Sentience

The difference between a cod and a lizard is not just a quantitative one. The recognition of qualitative differences between species does not imply a moral ranking. Our species’ special abilities to shape the earth mean we have a special responsibility for ensuring a liveable future for all organisms, human and non-human.


Black Bear Use Of Forest Roads In Western Washington, Gary W. Witmer Jan 2019

Black Bear Use Of Forest Roads In Western Washington, Gary W. Witmer

United States Department of Agriculture Wildlife Services: Staff Publications

Radiolocations (108) of 20 black bears were used to assess use or avoidance of 3 forest road types in western Washington. Distances of bears to each type of road were compared to distances of 108 random points using t-tests. Females and males avoided 2-lane roads, while only males avoided 1-lane roads, the most common road type in the area. Females, but not males, were located closer to overgrown, spur roads than expected. This road type has substantial cover of grasses, forbs, and berry-producing shrubs along with protective tree cover. This situation may provide easy travel for females along with security …


No Detection Of Brodifacoum Residues In The Marine And Terrestrial Food Web Three Years After Rat Eradication At Palmyra Atoll, Central Pacific, A. Wegmann, G. Howald, S. Kropidlowski, N. Holmes, A.B. Shiels Jan 2019

No Detection Of Brodifacoum Residues In The Marine And Terrestrial Food Web Three Years After Rat Eradication At Palmyra Atoll, Central Pacific, A. Wegmann, G. Howald, S. Kropidlowski, N. Holmes, A.B. Shiels

United States Department of Agriculture Wildlife Services: Staff Publications

Invasive alien species represent one of the greatest threats to native plants and animals on islands. Rats (Rattus spp.) have invaded most of the world’s oceanic islands, causing lasting or irreversible damage to ecosystems and biodiversity. To counter this threat, techniques to eradicate invasive rats from islands have been developed and applied across the globe. Eradication of alien rats from large or complex island ecosystems has only been successful with the use of bait containing a rodenticide. While effective at eradicating rats from islands, rodenticide can persist in the ecosystem longer than the time required to eradicate the target rat …


Home Range And Habitat Use Of West Virginia Canis Latrans (Coyote), Lauren M. Mastro, Dana J. Morin, Eric M. Gese Jan 2019

Home Range And Habitat Use Of West Virginia Canis Latrans (Coyote), Lauren M. Mastro, Dana J. Morin, Eric M. Gese

United States Department of Agriculture Wildlife Services: Staff Publications

Canis latrans (Coyote) has undergone a range expansion in the United States over the last century. As a highly opportunistic species, its home range and habitat use changes with ecological context. Coyotes were first reported in West Virginia in 1950 but were not commonly observed until the 1990s, and there is scant information on Coyotes in the region. We used telemetry data from 8 radiocollared Coyotes in West Virginia to estimate home-range size and third-order habitat selection. Home-range areas (95% utilization distributions; UDs) varied from 5.22 to 27.79 km2 (mean = 12.48 ± 2.61 km2), with highly concentrated use of …
