Birds, Bats And Minds. Tales Of A Revolutionary Scientist: Donald R. Griffin. Volume Three, Carolyn A. Ristau

eBooks

In this three-volume biography, we revisit the life and accomplishments of the revolutionary scientist, Donald R. Griffin. He encountered a lifetime of initial hostile resistance to his ideas and studies; now they are largely accepted. He and a colleague discovered the phenomenon of echolocation used by bats to navigate and capture insects, proposed that birds navigate guided by such cues as the sun and stars, and suggested that animals are likely aware, thinking and feeling beings. Forty interviews with his colleagues and friends help us understand the young emerging scientist and the mature researcher. We learn about his and others’ …

Defining And Assessing Sentience, Barry O. Hughes

Animal Sentience

Precisely what is meant by the term sentience and how does it overlap with being conscious? We accept that animals have feelings but how do we know what they are and can we measure them? It is important that we clarify the terminology underlying these difficult concepts. Over the last 50 years a scientific discipline has developed to tackle these questions in a systematic way. We have to avoid thoughtless anthropomorphism yet we have to try to relate sentience in animals, as appropriate, to corresponding experiences in humans.

Independence, Weight And Priority Of Evidence For Sentience, Elizabeth Irvine

Animal Sentience

This commentary maps out relationships of dependency between the criteria proposed in the target article (Crump et al. 2022), identifying the criteria that carry most of the weight of the evidence, and suggesting which criteria should have priority in research on sentience.

Emotional Component Of Pain Perception In The Medicinal Leech?, Brian D. Burrell

Animal Sentience

Crump et al. have provided a series of criteria to assess animal sentience that is focused on the perception of pain, which is known to have both sensory and emotional components. They also provide a qualitative scoring system to assess data that address the eight criteria and apply this paradigm to decapod crustaceans. The criteria laid out have the potential to be applied to other invertebrates typically thought to have sensory response to tissue damage, but no emotional component to pain perception.

The Question Is Not “Can Humans Talk?” Or “Can They Suffer?” But “Can They Reason?”, Clive Phillips

Animal Sentience

In their target article, Rowan et al (2022) make a welcome attempt to chart the development of Western progress over the past two hundred years toward formally recognizing that animals feel. They outline the heroic efforts of Compassion in World Farming to gain for animals the status of sentient beings rather than merely human property. A broader view exists, from human prehistory to the present day, in which animals have been (and still are) understood to be sentient by indigenous peoples as well as by some Eastern religions. Growing recognition in the West that animals feel represents a new age …

Sentience And Sentient Minds, John Anthony Webster

Animal Sentience

My commentary builds on Rowan et al.’s (2022) comprehensive review to address the question ‘what do we mean by sentience?’ It suggests how we might recognise degrees of sentience within the animal kingdom, ranging from primitive sensations such as hunger and pain to more complex emotions that determine quality of life.

Animal Sentience: History, Science, And Politics, Andrew N. Rowan, Joyce M. D'Silva, Ian J.H. Duncan, Nicholas Palmer

Animal Sentience

This target article has three parts. The first briefly reviews the thinking about nonhuman animals’ sentience in the Western canon: what we might know about their capacity for feeling, leading up to Bentham’s famous question “can they suffer?” The second part sketches the modern development of animal welfare science and the role that animal-sentience considerations have played therein. The third part describes the launching, by Compassion in World Farming, of efforts to incorporate animal sentience language into public policy and regulations concerning human treatment of animals.

Brain Complexity, Sentience And Welfare, Donald M. Broom

Animal Sentience

Neither sentience nor moral standing is confined to animals with large or human-like brains. Invertebrates deserve moral consideration. Definition of terms clarifies the relationship between sentience and welfare. All animals have welfare but humans give more protection to sentient animals. Humans should be less human-centred.

One Welfare, The Role Of Health Professionals, And Climate Change, Anne Fawcett

Animal Sentience

Wiebers & Feigin argue that the COVID-19 crisis is a call for humanity to rethink our relationships with animals and the environment. This One Welfare approach has implications for the role of health care professionals and demands that we address climate change.

Plant-Based Diets And Covid-19: Those Who Harvest Crops Are At High Risk, Jarret S. Lovell

Animal Sentience

This commentary extends Wiebers & Feigin’s (2020) plea to adopt diets that are less dependent on animals by calling on experts and activists to work for change with regard to farm worker labor conditions. Already doing among the most dangerous jobs, farmworkers are at increased risk of COVID-19. As we increasingly transition to plant-based diets, we must all ensure that farmworkers have safe and just working conditions to meet the demands of our changing diets.

Behavioural Risks In Female Dogs With Minimal Lifetime Exposure To Gonadal Hormones, Melissa J. Starling, Anne Fawcett, Bethany Wilson, James Serpell, Paul Mcgreevy

Physiology Collection

Spaying of female dogs is a widespread practice, performed primarily for population control. While the consequences of early spaying for health are still being debated, the consequences for behaviour are believed to be negligible. The current study focused on the reported behaviour of 8981 female dogs spayed before 520 weeks (ten years) of life for reasons other than behavioural management, and calculated their percentage lifetime exposure to gonadal hormones (PLGH) as a proportion of their age at the time of being reported to the online Canine Behavioral Assessment and Research Questionnaire (C-BARQ). We found that 23 behaviours differed between entire …

A Belmont Report For Animals?, Hope Ferdowsian, L. Syd M. Johnson, Jane Johnson, Andrew Fenton, Adam Shriver, John Gluck

Professional Science Research Ethics Collection

Human and animal research both operate within established standards. In the United States, criticism of the human research environment and recorded abuses of human research subjects served as the impetus for the establishment of the National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research, and the resulting Belmont Report. The Belmont Report established key ethical principles to which human research should adhere: respect for autonomy, obligations to beneficence and justice, and special protections for vulnerable individuals and populations. While current guidelines appropriately aim to protect the individual interests of human participants in research, no similar, comprehensive, …

Adaptation Of The Systematic Review Framework To The Assessment Of Toxicological Test Methods: Challenges And Lessons Learned With The Zebrafish Embryotoxicity Test, Martin L. Stephens, Sevcan Gül Akgün-Ölmez, Sebastian Hoffman, Rob De Vries, Burkhard Flick, Thomas Hartung, Manoj Lalu, Alexandra Maertens, Hilda Witters, Robert Wright, Katya Tsaioun

Toxicology and Animal Models in Research Collection

Systematic review methodology is a means of addressing specific questions through structured, consistent, and transparent examinations of the relevant scientific evidence. This methodology has been used to advantage in clinical medicine, and is being adapted for use in other disciplines. Although some applications to toxicology have been explored, especially for hazard identification, the present preparatory study is, to our knowledge, the first attempt to adapt it to the assessment of toxicological test methods. As our test case, we chose the zebrafish embryotoxicity test (ZET) for developmental toxicity and its mammalian counterpart, the standard mammalian prenatal development toxicity study, focusing the …

An Epidemiological Study Of Diabetes Mellitus In Dogs Attending First Opinion Practice In The Uk, Madeleine Mattin, Dan G. O'Neill, David B. Church, Paul D. Mcgreevy, Peter C. Thomson, Dave C. Brodbelt

Epidemiology Collection

Objectives: To estimate the prevalence of canine diabetes mellitus (DM) in primarycare clinics in England, to identify risk factors associated with DM and to describe the survival of affected dogs.

Methods: Cases of DM were identified within the electronic patient records of 89 small-animal practices. A nested case-control study identified risk factors for the diagnosis of DM using logistic regression models. Cox proportional hazards models were used to analyse variables associated with survival.

Results: Four-hundred and thirty-nine canine DM cases were identified, giving an apparent prevalence of 0.34% (95% confidence interval 0.31 - 0.37%). Neutered males were at an increased …

Contribution Of Animal Models To Contemporary Understanding Of Attention Deficit Hyperactivity Disorder, Constança Carvalho, Mariana Vieira Crespo, Luísa Ferreira Bastos, Andrew Knight, Luís Vincente

Biomedicine and Animal Models in Research Collection

Attention Deficit Hyperactivity Disorder (ADHD) is a poorly understood neurodevelopmental disorder of multifactorial origin. Animal-based research has been used to investigate ADHD etiology, pathogenesis and treatment, but the efficacy of this research for patients has not yet been systematically evaluated. Such evaluation is important given the resource consumption and ethical concerns incurred by animal use.

We used the citation tracking facility within Web of Science to locate citations of original research papers on animal models related to ADHD published prior to 2010 identified in PubMed by relevant search terms. Human medical papers citing those animal studies were carefully analyzed by …

Goats Distinguish Between Positive And Negative Emotion-Linked Vocalisations, Luigi Baciadonna, Elodie Briefer, Livio Favaro, A. G. Mcelligott

Bioacoustics Collection

Background: Evidence from humans suggests that the expression of emotions can regulate social interactions and promote coordination within a group. Despite its evolutionary importance, social communication of emotions in non-human animals is still not well understood. Here, we combine behavioural and physiological measures, to determine if animals can distinguish between vocalisations linked to different emotional valences (positive and negative). Using a playback paradigm, goats were habituated to listen to a conspecific call associated with positive or negative valence (habituation phase) and were subsequently exposed to a variant of the same call type (contact call) associated with the opposite valence (dishabituation …

Publication Reform To Safeguard Wildlife From Researcher Harm, Kate A. Field, Paul C. Paquet, Kyle A. Artelle, Gilbert Proulx, Ryan K. Brook, Chris T. Darimont

Professional Science Research Ethics Collection

Despite abundant focus on responsible care of laboratory animals, we argue that inattention to the maltreatment of wildlife constitutes an ethical blind spot in contemporary animal research. We begin by reviewing significant shortcomings in legal and institutional oversight, arguing for the relatively rapid and transformational potential of editorial oversight at journals in preventing harm to vertebrates studied in the field and outside the direct supervision of institutions. Straightforward changes to animal care policies in journals, which our analysis of 206 journals suggests are either absent (34%), weak, incoherent, or neglected by researchers, could provide a practical, effective, and rapidly imposed …

Canine Dystocia In 50 Uk First-Opinion Emergency Care Veterinary Practices: Clinical Management And Outcomes, Dan G. O'Neill, Aoife M. O'Sullivan, Erin A. Manson, David B. Church, Paul Mcgreevy, Amanda K. Boag, Dave C. Brodbelt

Natology Collection

Canine dystocia is a relatively common veterinary presentation. First opinion emergency care clinical data from 50 Vets Now clinics across the UK were used to explore dystocia management and outcomes in bitches. Caesarean section (CS) was performed on 341/701 (48.6 per cent (95 per cent CI 44.9 to 52.4)) of dystocia cases. The bulldog (OR 7.60, 95 per cent CI 1.51 to 38.26, P=0.014), Border terrier (OR 4.89, 95 per cent CI 0.92 to 25.97, P=0.063) and golden retriever (OR 4.07, 95 per cent CI 0.97 to 17.07, P=0.055) had the highest odds of CS among dystocic bitches compared with …

Welfare Challenges Influence The Complexity Of Movement: Fractal Analysis Of Behaviour In Zebrafish, Anthony G. Deakin, Joseph W. Spencer, Andrew R. Cossins, Iain S. Young, Lynne U. Sneddon

Experimental Research and Animal Welfare Collection

The ability to assess welfare is an important refinement that will ensure the good condition of animals used in experimentation. The present study investigated the impact of invasive procedures on the patterns of movement of zebrafish (Danio rerio). Recordings were made before and after fin clipping, PIT tagging and a standard pain test and these were compared with control and sham handled zebrafish. The fractal dimension (FD) from the 3D trajectories was calculated to determine the effect of these treatments on the complexity of movement patterns. While the FD of zebrafish trajectories did not differ over time in either the …

Non-Human Animals Providing Rescue In Medical Emergencies, Rainer Spiegel

Animal Sentience

In their target article, Chapman & Huffman challenge the quotation of Sir William Osler that the desire to take medication distinguishes humans from non-human animals. They provide examples of self-medication in non-human animals. Based on these examples, it can be inferred that non-human animals practice at least some form of medicine for symptom control. I would like to extend this view by showing that non-human animals not only provide self-medication, but also rescue others facing emergencies.

Retrospective Review Of Anesthetic And Analgesic Regimens Used In Animal Research Proposals, Kathrin Herrmann, Paul A. Flecknell

Experimental Research and Animal Welfare Collection

Pain has a profound effect on an animal’s wellbeing. In Germany, researchers using animals have been legally required to reduce any possible pain, suffering, distress or lasting harm to an absolute minimum since 1972. To evaluate how these provisions have been implemented in practice, an assessment of refinements to experimental techniques was conducted by retrospectively reviewing 684 surgical interventions described in 506 animal research applications that were sent to the German competent authorities for approval in 2010. This paper focuses on the efficacy of proposed anesthesia and peri- and postoperative analgesia. Postoperative analgesia was not proposed for 30% of surgeries. …

Consequences And Management Of Canine Brachycephaly In Veterinary Practice: Perspectives From Australian Veterinarians And Veterinary Specialists, Anne Fawcett, Vanessa Barrs, Magdoline Awad, Georgina Child, Laurencie Brunel, Erin Mooney, Fernando Martinez-Taboada, Beth Mcdonald, Paul Mcgreevy

Professional Veterinary Ethics Collection

This article, written by veterinarians whose caseloads include brachycephalic dogs, argues that there is now widespread evidence documenting a link between extreme brachycephalic phenotypes and chronic disease, which compromises canine welfare. This paper is divided into nine sections exploring the breadth of the impact of brachycephaly on the incidence of disease, as indicated by pet insurance claims data from an Australian pet insurance provider, the stabilization of respiratory distress associated with brachycephalic obstructive airway syndrome (BOAS), challenges associated with sedation and the anaesthesia of patients with BOAS; effects of brachycephaly on the brain and associated neurological conditions, dermatological conditions associated …

Contesting Animal Experiments Through Ethics And Epistemology: In Defense Of A Political Critique Of Animal Experimentation, Arianna Ferrari

Professional Science Research Ethics Collection

Generally, an animal experiment can be defined as an intervention on an animal, which causes suffering, harm, and distress, for scientific purposes. In this definition, animal experiments differ from more general scientific investigations concerning animals, such as observational studies in the wild in the fields of ethology or conservation, in which animals are involved but may not be harmed. Nowadays, the use of the term vivisection, in the case of animal experiments, is very controversial. This term originally referred to the cutting of living bodies for scientific purposes and has a long conceptual history (Maehle, 1992). In ancient times, it …

Ethics, Efficacy, And Decision-Making In Animal Research, Lawrence A. Hansen, Kori Ann Kosberg

Morality and Ethics of Animal Experimentation Collection

Few would disagree with the ethical contention that if cruelty to animals is not wrong, then nothing is wrong. In fact, it is not only wrong, but in most states in the us, it is a crime, a felony no less. And yet, intentionally inflicting pain and suffering upon animals, which meets Webster’s definition of cruelty, is routinely countenanced when vivisection (from the Latin vivi, to be alive, and secare, to cut) is performed under license for biomedical research. Deciding to embrace, or reject, or limit animal research demands our best ethical judgment; and it is complicated by factual disputes …

Human Wrongs In Animal Research: A Focus On Moral Injury And Reification, Jane Johnson, Anna Smajdor

Morality and Ethics of Animal Experimentation Collection

Using arguments derived from the work of Axel Honneth (2006), we show that animal research involves an institutionalized failure to recognize nonhuman animals that not only reifies animals but the human persons engaged in this process, diminishing the scope of their moral agency and causing moral injury. In this chapter, we begin by briefly articulating the harms to animals in research and the more conventional harms to humans that can arise as a result of animal research, before making a case for the ethical damage wrought by the failures of recognition inherent within the system of animal research. We conclude …

The Moral Status Of Animal Research Subjects In Industry: A Stakeholder Analysis, Sarah Kenehan

Morality and Ethics of Animal Experimentation Collection

The use of non-human animals (hereinafter referred to as animals) in research and testing is a widely accepted practice in many industries. Millions of animals each year are subjected to painful procedures that include everything from physical mutilation to drug addiction. According to the United States Department of Agriculture (usda), over 820,812 animals were experimented on in the United States in 2016 (usda, 2017), though this count does not include rats, mice, or birds, and dubiously relies solely on the self-reporting of laboratories (Humane Society of the United States, 2011; Keen, 2019, Chapter 10 in this Volume). Estimates suggest that …

Ethical And Scientific Pitfalls Concerning Laboratory Research With Non-Human Primates, And Possible Solutions, Constança Carvalho, Augusta Gaspar, Andrew Knight, Luís Vicente

Morality and Ethics of Animal Experimentation Collection

Basic and applied laboratory research, whenever intrusive or invasive, presents substantial ethical challenges for ethical committees, be it with human beings or with non-human animals. In this paper we discuss the use of non-human primates (NHPs), mostly as animal models, in laboratory based research. We examine the two ethical frameworks that support current legislation and guidelines: deontology and utilitarianism. While human based research is regulated under deontological principles, guidelines for laboratory animal research rely on utilitarianism. We argue that the utilitarian framework is inadequate for this purpose: on the one hand, it is almost impossible to accurately predict the benefits …

Modernizing Biomedical Training: Replacing Live Animal Laboratories With Human Simulation, John Pawlowski, David Feinstein, Marie L. Crandall, Shalin Gala

Biomedicine and Animal Models in Research Collection

This chapter reviews the global trend towards a modernization of biomedical education in favor of simulation-based training methods, which studies confirm improve student learning and transference of applied skills to clinical practice, reduce laboratory costs, and spare animals from harmful procedures.
