Insects Have Agency But Probably Not Sentience Because They Lack Social Bonding, J. H. Van Hateren Aug 2016

Insects Have Agency But Probably Not Sentience Because They Lack Social Bonding, J. H. Van Hateren

Animal Sentience

Klein & Barron (2016) argue that insects have sentience because of functional similarities between the insect brain and vertebrate midbrain. Based on a recent theory of agency and consciousness, I argue that the functional similarities merely point to an advanced form of agency. Insects presumably lack the capacity for social bonding that may be required for subjective experiencing.

Neutering Of German Shepherd Dogs: Associated Joint Disorders, Cancers And Urinary Incontinence, Benjamin L. Hart, Lynette A. Hart, Abigail P. Thigpen, Neil H. Willits Aug 2016

Neutering Of German Shepherd Dogs: Associated Joint Disorders, Cancers And Urinary Incontinence, Benjamin L. Hart, Lynette A. Hart, Abigail P. Thigpen, Neil H. Willits

Endocrinology Collection

German Shepherd Dogs are important in police and military work, and are a popular family pet. The debilitating joint disorders of hip dysplasia, cranial cruciate ligament tear (CCL) and elbow dysplasia can shorten a dog’s useful working life and impact its role as a family member. For this study, veterinary hospital records were examined over a 14.5-year period on 1170 intact and neutered (including spaying) German Shepherd Dogs for joint disorders and cancers previously associated with neutering. The diseases were followed through 8 years of age, with the exception of mammary cancer (MC) in females that was followed through 11 …

Insulin-Dependent Glucose Metabolism In Dairy Cows With Variable Fat Mobilization Around Calving, C. Weber, C. T. Schäff, U. Kautzsch, S. Börner, S. Erdmann, S. Görs, M. Röntgen, H. Sauerwein, R. M. Bruckmaier, C. C. Metges, B. Kuhla, H. M. Hammon Aug 2016

Insulin-Dependent Glucose Metabolism In Dairy Cows With Variable Fat Mobilization Around Calving, C. Weber, C. T. Schäff, U. Kautzsch, S. Börner, S. Erdmann, S. Görs, M. Röntgen, H. Sauerwein, R. M. Bruckmaier, C. C. Metges, B. Kuhla, H. M. Hammon

Physiology Collection

Dairy cows undergo significant metabolic and endocrine changes during the transition from pregnancy to lactation, and impaired insulin action influences nutrient partitioning toward the fetus and the mammary gland. Because impaired insulin action during transition is thought to be related to elevated body condition and body fat mobilization, we hypothesized that over-conditioned cows with excessive body fat mobilization around calving may have impaired insulin metabolism compared with cows with low fat mobilization. Nineteen dairy cows were grouped according to their average concentration of total liver fat (LFC) after calving in low [LLFC; LFC <24% total fat/dry matter (DM); n = 9] and high (HLFC; LFC >24.4% total fat/DM; n = 10) fat-mobilizing …

Caterpillars, Consciousness And The Origins Of Mind, Arthur S. Reber Jul 2016

Caterpillars, Consciousness And The Origins Of Mind, Arthur S. Reber

Animal Sentience

A novel framework for the origins of consciousness and mind, the Cellular Basis of Consciousness (CBC), is presented. The model is based on a simple, perhaps radical axiom: subjectivity is an inherent feature of particular kinds of organic form. Experiential states, including those denoted as "mind" and "consciousness," are present in the most primitive species. The model has several conceptual and empirical virtues, among them: (a) it (re)solves the problem of how minds are created by brains ─ also known as the "Hard Problem" (Chalmers 1995) ─ by revealing that the apparent difficulty results from a category error, (b) it …

Why Animals Are Persons, Tony Cheng Jul 2016

Why Animals Are Persons, Tony Cheng

Animal Sentience

Rowlands’s case for attributing personhood to lower animals is ultimately convincing, but along the way he fails to highlight several distinctions that are crucial for his argument: Personhood vs. personal identity; the first person vs. its mental episodes; and pre-reflective awareness in general vs. one specific case of it.

"Beyond Words," Yes, But Also Beyond Numbers, Fred L. Bookstein Jul 2016

"Beyond Words," Yes, But Also Beyond Numbers, Fred L. Bookstein

Animal Sentience

Safina’s fascinating series of fifty separate feuilletons tries to bridge a painful Methodenstreit in contemporary ethology mainly by an accumulation of anecdotes. Some deal with his own dogs, but most derive from reading or conversing with observers of a wider range of social mammals including elephants, wolves, apes, and whales. In spite of the many interruptions by travesties of the academic lifestyle and its literature, there is a point to be made, concerning the centrality of evidence about cooperative behavior styles, especially aspects of child-rearing, for the understanding of “what animals think and feel.” But Safina’s argument would be a …

Animals Are Agents, Linda A.W. Brakel Jul 2016

Animals Are Agents, Linda A.W. Brakel

Animal Sentience

Mark Rowlands’s (2016) target article invites us to consider individuals in a broad subset of the non-human animal world as genuine persons. His account features animals reacting to salient environmental stimuli as Gibsonian affordances, which is indicative of “pre-reflective self-awareness.” He holds that such pre-reflective self-awareness is both “immune to error through misidentification” (Shoemaker, 1968) and a necessary precursor to reflective consciousness and personhood. I agree. In this commentary I hope to extend Rowlands’s work with a view in which agency is an even more fundamental precursor and one can (and should) consider individuals throughout the entire animal kingdom as …

Implicit Mental Processes Are An Improbable Basis For Personhood, Michael L. Woodruff Jul 2016

Implicit Mental Processes Are An Improbable Basis For Personhood, Michael L. Woodruff

Animal Sentience

Rowlands argues that animals have implicit pre-reflective awareness and that this is adequate to create the unity of conscious thought required for personhood. For him pre-reflective awareness does not include intentionality and is probably an unconscious process. I suggest that his sense of implicit leads to significant difficulties for his argument and that including intentionality in the definition of a first-person perspective provides a stronger base for viewing animals as persons.

Japanese Small Type Coastal Whaling, Sue Fisher Jul 2016

Japanese Small Type Coastal Whaling, Sue Fisher

Commercial Whaling Collection

2016 marks the 70th anniversary of the International Convention for the Regulation of Whaling (ICRW) as well as the 30th anniversary of the International Whaling Commission’s (IWC) moratorium on commercial whaling. It also marks three decades of effort by Japan to overturn this ban. Its strategy to circumvent the moratorium by issuing permits to kill protected whales for scientific research is famous—even the subject of a 2014 lawsuit at the International Court of Justice. Less well known is Japan’s strategy to overturn the ban by persuading the Commission to authorize a category of commercial whaling known as Small Type Coastal …

Are Animals Persons?, Mark Rowlands Jul 2016

Are Animals Persons?, Mark Rowlands

Animal Sentience

It is orthodox to suppose that very few, if any, nonhuman animals are persons. The category “person” is restricted to self-aware creatures: humans (above a certain age) and possibly some of the great apes and cetaceans. I argue that this orthodoxy should be rejected, because it rests on a mistaken conception of the kind of self-awareness relevant to personhood. Replacing this with a sense of self-awareness that is relevant requires us to accept that personhood is much more widely distributed through the animal kingdom.

Insects Have The Capacity For Subjective Experience, Colin Klein, Andrew B. Barron Jul 2016

Insects Have The Capacity For Subjective Experience, Colin Klein, Andrew B. Barron

Animal Sentience

To what degree are non-human animals conscious? We propose that the most meaningful way to approach this question is from the perspective of functional neurobiology. Here we focus on subjective experience, which is a basic awareness of the world without further reflection on that awareness. This is considered the most basic form of consciousness. Tellingly, this capacity is supported by the integrated midbrain and basal ganglia structures, which are among the oldest and most highly conserved brain systems in vertebrates. A reasonable inference is that the capacity for subjective experience is both widespread and evolutionarily old within the vertebrate lineage. …

Utilitarianism Generalized To Include Animals, Yew-Kwang Ng Jul 2016

Utilitarianism Generalized To Include Animals, Yew-Kwang Ng

Animal Sentience

In response to the seventeen commentaries to date on my target article on reducing animal suffering, I propose that the term “welfarism” (when used pejoratively by animal advocates) should be qualified as “anthropocentric welfarism” so as to leave “welfarism” simpliciter to be used in its generic sense of efforts to improve conditions for those who need it. Welfarism in this benign sense — even in its specific utilitarian form (maximizing the sum total of net welfare) with long-term future effects and effects on others (including animals) appropriately taken into account — should be unobjectionable (even if not considered sufficient by …

Cross-Species Mind-Reading, Stevan Harnad Jul 2016

Cross-Species Mind-Reading, Stevan Harnad

Animal Sentience

We can never be sure anyone else is sentient. But we can be sure enough in the case of other people, nonhuman primates, mammals, birds, fish, lower vertebrates and invertebrates as to make scepticism academic and otiose (not to mention monumentally cruel). The only genuinely uncertain kinds of cases are jellyfish, microbes and plants. The rest is not about whether but what they are feeling.

My Orgasms Cannot Be Traded Off Against Others’ Agony, Stevan Harnad Jul 2016

My Orgasms Cannot Be Traded Off Against Others’ Agony, Stevan Harnad

Animal Sentience

Only I can calculate my own welfare as net pleasure minus pain. No one else can do that calculation for me – nor for a population, and especially not averaging across some individuals’ pleasure and other individuals’ pain. Pain and pleasure are incommensurable and only pain matters morally. To maximize welfare is to minimize pain.

In Praise Of Fishes: Précis Of What A Fish Knows (Balcombe 2016), Jonathan Balcombe Jul 2016

In Praise Of Fishes: Précis Of What A Fish Knows (Balcombe 2016), Jonathan Balcombe

Animal Sentience

Our relationship to fishes in the modern era is deeply problematic. We kill and consume more of them than any other group of vertebrates. At the same time, advances in our knowledge of fishes and their capabilities are gaining speed. Fish species diversity exceeds that of all other vertebrates combined, with a wide range of sensory adaptations, some of them (e.g., geomagnetism, water pressure and movement detection, and communication via electricity) alien to our own sensory experience. The evidence for pain in fishes (despite persistent detractors) is strongly supported by anatomical, physiological and behavioral studies. It is likely that fishes …

Sentience As Moral Consideration And Disvalue In Nature, Daniel Dorado Jul 2016

Sentience As Moral Consideration And Disvalue In Nature, Daniel Dorado

Animal Sentience

In recent work Ng assumes that it is good to engage in activities aimed at promoting ecosystem conservation. The only way Ng can derive this from the axiology he assumes (the view that wellbeing is the only intrinsically valuable or disvaluable thing) would be to assume that ecosystem conservation would benefit the individuals involved. This can be so as long as value prevails over disvalue in the target environments. Ng seems to assume this is indeed the case, but he does not explain why, and it is a claim that goes against the conclusions he has argued for previously (Ng …

Inalienable Rights And Pluralism In Animal Advocacy, Beril Sözmen Jul 2016

Inalienable Rights And Pluralism In Animal Advocacy, Beril Sözmen

Animal Sentience

I comment on two of Ng’s suggestions. There is a lack of support for his suggestion that some experiments on individual animals will be useful for future success, so they should be permitted. I also question his recommendation that animal advocacy should focus on farmed animals first and wild animals later. The lack of solid support for why this would be a more effective strategy leads me to suggest a more pluralistic support of a variety of types of advocacy.

The Grounds For Animal Subjectivity And Intersubjectivity, Timothy P. Racine Jul 2016

The Grounds For Animal Subjectivity And Intersubjectivity, Timothy P. Racine

Animal Sentience

Harnad (2016) presents an engaging and persuasive argument that stakes out the aims and domain of the fledgling journal, Animal Sentience. As an inaugural editorial, it does this job masterfully, but it does so from a perspective that tends to treat mental states in an overly general manner and that makes hard distinctions between mental and behavioral phenomena. I argue that when it comes to animal minds, it might be more helpful to think of mental concepts in a more piecemeal way that also retains the intrinsic relation between mind and behavior.

Changing Attitudes Towards Animals In The Wild And Speciesism, Oscar Horta Jul 2016

Changing Attitudes Towards Animals In The Wild And Speciesism, Oscar Horta

Animal Sentience

I argue that despite Ng’s claim that we should postpone the defense of those animals that live in the wild, we do have reasons to start spreading concern for them now. We can do it by (i) changing public attitude by heightening awareness of speciesism, by which we will also challenge animal exploitation; and (ii) by disseminating information about the situation of animals in the wild.

Vocal Individuality And Species Divergence In The Contact Calls Of Banded Penguins, Livio Favaro, Claudia Gili, Cristiano Da Rugna, Guido Gnone, Chiara Fissore, Daniel Sanchez, Alan G. Mcelligott, Marco Gamba, Daniela Pessani Jul 2016

Vocal Individuality And Species Divergence In The Contact Calls Of Banded Penguins, Livio Favaro, Claudia Gili, Cristiano Da Rugna, Guido Gnone, Chiara Fissore, Daniel Sanchez, Alan G. Mcelligott, Marco Gamba, Daniela Pessani

Bioacoustics Collection

Penguins produce contact calls to maintain social relationships and group cohesion. Such vocalisations have recently been demonstrated to encode individual identity information in the African penguin. Using a source-filter theory approach, we investigated whether acoustic cues of individuality can also be found in other Spheniscus penguins and the acoustic features of contact calls have diverged within this genus. We recorded vocalisations from two ex-situ colonies of Humboldt penguin and Magellanic penguin (sympatric and potentially interbreeding in the wild) and one ex-situ group of African penguins (allopatric although capable of interbreeding with the other two species in captivity). We measured 14 …

On-Farm Qualitative Behaviour Assessment Of Dairy Goats In Different Housing Conditions, Lilia Grosso, Monica Battini, Françoise Wemelsfelder, Sara Barbieri, Michela Minero, Emanuela Dalla Costa, Silvana Mattiello Jul 2016

On-Farm Qualitative Behaviour Assessment Of Dairy Goats In Different Housing Conditions, Lilia Grosso, Monica Battini, Françoise Wemelsfelder, Sara Barbieri, Michela Minero, Emanuela Dalla Costa, Silvana Mattiello

Sentience Collection

This study reports the results of the first investigation on the use of Qualitative Behaviour Assessment (QBA) in dairy goats, using a fixed-list of descriptors specifically developed for this species. It aimed to verify whether QBA can be reliably used by observers with different backgrounds to differentiate between the emotional states of goats kept under different environmental conditions. Two trained observers simultaneously assessed 16 dairy goat farms (8 “Housed” (H) farms, where animals were observed in free stall pens, and 8 “Pasture” (P) farms, where animals were observed in open ranges), using a list of 16 QBA descriptors that were …

Goats Display Audience-Dependent Human-Directed Gazing Behaviour In A Problem-Solving Task, Christian Nawroth, Jemma M. Brett, Alan G. Mcelligott Jul 2016

Goats Display Audience-Dependent Human-Directed Gazing Behaviour In A Problem-Solving Task, Christian Nawroth, Jemma M. Brett, Alan G. Mcelligott

Social Cognition Collection

Domestication is an important factor driving changes in animal cognition and behaviour. In particular, the capacity of dogs to communicate in a referential and intentional way with humans is considered a key outcome of how domestication as a companion animal shaped the canid brain. However, the lack of comparison with other domestic animals makes general conclusions about how domestication has affected these important cognitive features difficult. We investigated human-directed behaviour in an ‘unsolvable problem’ task in a domestic, but non-companion species: goats. During the test, goats experienced a forward facing or an away facing person. They gazed towards the forward …

Why We Should Not Postpone Awareness Of Wild Animal Suffering, Catia Faria Jun 2016

Why We Should Not Postpone Awareness Of Wild Animal Suffering, Catia Faria

Animal Sentience

Ng (2016) restates his case for the importance of wild animal suffering (1995). Nevertheless, he suggests that the most effective way to reduce nonhuman suffering overall is to give short-term priority to the suffering of farmed animals. It is not clear that Ng puts forward a successful case. Our current efforts to prevent animal suffering overall should also include raising awareness of wild animal suffering now as well as promoting research on safe and feasible ways to prevent wild animal suffering in the future.

An Overview Of Increasing Incidents Of Bottlenose Dolphin Harassment In The Gulf Of Mexico And Possible Solutions, Courtney S. Vail Jun 2016

An Overview Of Increasing Incidents Of Bottlenose Dolphin Harassment In The Gulf Of Mexico And Possible Solutions, Courtney S. Vail

Human-Animal Interactions Collection

The panhandle region of the Gulf of Mexico is known by scientists, regulatory agencies and conservation organizations as a “hotbed” area of dolphin harassment. Interactions between humans and wild dolphins routinely occur through close vessel approaches or through direct contact associated with commercial or recreational fisheries, swimwith, or feeding activities. Such interactions are of serious concern for wild dolphin welfare and conservation under the U.S. Marine Mammal Protection Act, as well as for human safety. In recent years, an alarming number of dolphins in this region have been fatally wounded by gunshot, hunting arrows, or sharp tools (i.e., screwdriver). The …

Marine Mammal Behavior: A Review Of Conservation Implications, Philippa Brakes, Sasha R. X. Dall Jun 2016

Marine Mammal Behavior: A Review Of Conservation Implications, Philippa Brakes, Sasha R. X. Dall

Social Behavior Collection

The three orders which comprise the extant marine mammals exhibit a wide range of behaviors, varying social structures, and differences in social information use. Human impacts on marine mammals and their environments are ubiquitous; from chemical and noise pollution, to marine debris, prey depletion, and ocean acidification. As a result, no marine mammal populations remain entirely unaffected by human activities. Conservation may be hindered by an inadequate understanding of the behavioral ecology of some of these species. As a result of social structure, social information use, culture, and even behavioral syndromes, marine mammal social groups, and populations can be behaviorally …
