What Would The Babel Fish Say?, Monica Gagliano
What Would The Babel Fish Say?, Monica Gagliano
Animal Sentience
Starting with its title, Key’s (2016) target article advocates the view that fish do not feel pain. The author describes the neuroanatomical, physiological and behavioural conditions involved in the experience of pain in humans and rodents and confidently applies analogical arguments as though they were established facts in support of the negative conclusion about the inability of fish to feel pain. The logical reasoning, unfortunately, becomes somewhat incoherent, with the arbitrary application of the designated human criteria for an analogical argument to one animal species (e.g., rodents) but not another (fish). Research findings are reported selectively, and questionable interpretations are …

From Sentience To Science: Limits Of Anthropocentric Cognition, Charukeshi Chandrasekera
Animal Sentience
Donald Broom’s Sentience and Animal Welfare (2014) is an intellectually and morally engaging book written with radical new concepts in mind. It deals with many issues that are central to the animal welfare debate such as brain complexity, cognitive ability, when in life sentience begins, and how it all affects the way we endorse welfare. It addresses how our insatiable quest to define the uniqueness of our own species has led us to ignore logic and scientific evidence. It also brings greater clarity to these precarious positions and outlines pragmatic approaches to tackling this complex topic of sentience and welfare.
Animal Welfare And Animal Rights, M.E. Rolle
Animal Welfare And Animal Rights, M.E. Rolle
Animal Sentience
This overview of Broom’s book, Sentience and Animal Welfare (2014), considers the role the book could play in the animal rights debate. In a thoroughly researched and objectively presented text, Broom lays out information that could place doubt in the minds of decision-makers. By highlighting not just the ways animals resemble humans, but also the ways humans resemble animals, Broom shines a light on a solidly grey area in the animal rights debate.
Is Humanitarianism Recent?, Andrea L. Sammarco
Is Humanitarianism Recent?, Andrea L. Sammarco
Animal Sentience
Although there is the need for textbooks in this field, the literary style of Broom’s Sentience and Animal Welfare detracts from the readability of the book. The author attempts with mixed success to define the field and differing opinions regarding the definitions of “sentience” and “animal welfare,” but makes a number of questionable assumptions concerning the history of the subject area.
Anticipatory Grief, Tara Fox Hall
Anticipatory Grief, Tara Fox Hall
Animal Sentience
This commentary reviews Barbara King’s How Animals Grieve, delving into the controversial topic of the status of animals in our society, as well as the key difference between human and non-human grief: the ability to anticipate death.
Monkey Say, Monkey Do, Monkey Grieve?, Helen Proctor
Monkey Say, Monkey Do, Monkey Grieve?, Helen Proctor
Animal Sentience
In this commentary, I have focused on King’s chapter “Do monkeys mourn?” and discussed the complexity that this question unearths. Attempting to answer this question, King has scoured the literature and talked to many primatologists to try to unravel the complex reactions seen in monkeys. From ignorance to denial, and everything in between, monkeys appear to react to death in countless ways. This commentary discusses some of the key cases for and against monkey grief, and concludes by noting the dearth of conclusive literature on one of the most studied groups of animals.

Transport of Farm Animals Collection
Equine transportation is associated with a variety of serious health disorders causing economic losses. However; statistics on horse transport are limited and epidemiological data on transport related diseases are available only for horses transported to abattoirs for slaughter. This study analysed reports of transport related health problems identified by drivers and horse owners for 180 journeys of an Australian horse transport company transporting horses between Perth and Sydney (~4000 km) in 2013–2015. Records showed that 97.2% (1604/1650) of the horses arrived at their destination with no clinical signs of disease or injury. Based on the veterinary reports of the affected …
Influence Of Rock-Pool Characteristics On The Distribution And Abundance Of Inter-Tidal Fishes, Gemma E. White, Grant C. Hose, Culum Brown
Influence Of Rock-Pool Characteristics On The Distribution And Abundance Of Inter-Tidal Fishes, Gemma E. White, Grant C. Hose, Culum Brown
Ecology Collection
Rock pools can be found in inter-tidal marine environments worldwide; however, there have been few studies exploring what drives their, fish species composition, especially in Australia. The rock-pool environment is highly dynamic and offers a unique natural laboratory to study the habitat choices, physiological limitations and adaptations of inter-tidal fish species. In this study rock pools of the Sydney region were sampled to determine how the physical (volume, depth, rock cover and vertical position) and biological (algal cover and predator presence) parameters of pools influence fish distribution and abundance. A total of 27 fish species representing 14 families was observed …

Autonomic Nervous System Reactivity In A Free-Ranging Mammal: Effects Of Dominance Rank And Personality, Elodie F. Briefer, James A. Oxley, Alan G. Mcelligott
Ethology Collection
Modulation of the autonomic nervous system (ANS) activity allows animals to effectively respond to internal and external stimuli in everyday challenges via changes in, for example, heart and respiration rate. Various factors, ranging from social such as dominance rank to internal such as personality or affective states can impact animal physiology. Our knowledge of the combinatory effects of social and internal factors on ANS basal activity and reactivity, and of the importance that each factor has in determining physiological parameters, is limited, particularly in nonhuman, free-ranging animals. In this study, we tested the effects of dominance rank and personality (assessed …
Predicting Human Drug Toxicity And Safety Via Animal Tests: Can Any One Species Predict Drug Toxicity In Any Other, And Do Monkeys Help?, Jarrod Bailey, Michelle Thew, Michael Balls
Predicting Human Drug Toxicity And Safety Via Animal Tests: Can Any One Species Predict Drug Toxicity In Any Other, And Do Monkeys Help?, Jarrod Bailey, Michelle Thew, Michael Balls
Laboratory Experiments Collection
Animals are still widely used in drug development and safety tests, despite evidence for their lack of predictive value. In this regard, we recently showed, by producing Likelihood Ratios (LRs) for an extensive data set of over 3,000 drugs with both animal and human data, that the absence of toxicity in animals provides little or virtually no evidential weight that adverse drug reactions will also be absent in humans. While our analyses suggest that the presence of toxicity in one species may sometimes add evidential weight for risk of toxicity in another, the LRs are extremely inconsistent, varying substantially for …

Housing and Confinement of Farm Animals Collection
The energy-related products Directive (ErP) 2009/125/EC has set a new generation of equipment that are more energy efficient and reliable. In the case of climate control for livestock housing, a key role can be played by EC motors direct drive variable flow fans that can be used instead of traditional AC fans in applications like broiler or dairy houses. The energy consumptions of such fans strictly depend on the specific application and on the outdoor weather conditions, and there is therefore the need to forecast their energy performance by means of computational tools. In this work, we present a tool …

Wildlife In U.S. Cities: Managing Unwanted Animals, John Hadidian
Conservation Collection
Conflicts between people and wild animals in cities are undoubtedly as old as urban living itself. In the United States it is only of late, however, that many of the species now found in cities have come to live there. The increasing kind and number of human-wildlife conflicts in urbanizing environments makes it a priority that effective and humane means of conflict resolution be found. The urban public wants conflicts with wildlife resolved humanely, but needs to know what the alternative management approaches are, and what ethical standards should guide their use. This paper examines contemporary urban wildlife control in …

Understanding concerns about the welfare of farm animals is important for the development of socially sustainable production practices. This study used an online survey to test how views on group versus stall housing for pregnant sows varied when Canadian and US participants were provided information about these systems, including access to scientific papers, YouTube videos, Google images, and a frequently-asked-questions page (S1 Appendix). Initial responses and changes in responses after accessing the information were analyzed from Likert scores of 242 participants and from their written comments. Participants were less willing to accept the use of gestation stalls after viewing information …

Physiology Collection
Stereotypies are repetitive and relatively invariant patterns of behavior, which are observed in a wide range of species in captivity. Stereotypic behavior occurs when environmental demands produce a physiological response that, if sustained for an extended period, exceeds the natural physiological regulatory capacity of the organism, particularly in situations that include unpredictability and uncontrollability. One hypothesis is that stereotypic behavior functions to cope with stressful environments, but the existing evidence is contradictory. To address the coping hypothesis of stereotypies, we triggered physiological reactions in 22 horses affected by stereotypic behavior (crib-biters) and 21 non-crib-biters (controls), using an ACTH challenge test. …

Veganism As An Aspiration, Lori Gruen, Robert C. Jones
Dietary Choice and Foods of Animal Origin Collection
iven the violence, objectification, domination, commodification, and oppression inherent in industrialized food production, some conscientious consumers have adopted vegan practices. This chapter discusses two conceptions of veganism, lifestyle/identity veganism, VI, and veganism as a goal/aspiration, VA. It argues that due to conceptual and practical flaws with VI, conscientious consumers should adopt VA. It considers and rejects the so-called compassionate carnivore movement. It then explores arguments denying the casual efficacy of adopting any form of veganism. It concludes that VA can make a difference, and those in consumer cultures are obligated to adopt and practice it.

Laterality Enhances Numerical Skills In The Guppy, Poecilia Reticulata, Marco Dadda, Christian Agrillo, Angelo Bisazza, Culum Brown
Sentience Collection
It has been hypothesized that cerebral lateralization can significantly enhance cognition and that this was one of the primary selective forces shaping its wide-spread evolution amongst vertebrate taxa. Here, we tested this hypothesis by examining the link between cerebral lateralization and numerical discrimination. Guppies, Poecilia reticulata, were sorted into left, right and non-lateralized groups using a standard mirror test and their numerical discrimination abilities tested in both natural shoal choice and abstract contexts. Our results show that strongly lateralized guppies have enhanced numerical abilities compared to non-lateralized guppies irrespective of context. These data provide further credence to the notion that …

This report presents findings regarding the ways to optimise the performance of livestock working dogs in Australia. The methods available to optimise dog performance include both environmental and genetic factors. The objectives of this study were to identify objective measures of desirable behavioural phenotypes in Australian livestock working dogs and explore genetic parameters of these 'quality of working life' traits within the Kelpie breed. The document reports on genotyping that reveals gene-behaviour associations and describes heritability estimates that underpin a database for potential estimated breeding value (EBV) calculations.
The Flaws And Human Harms Of Animal Experimentation, Aysha Akhtar
The Flaws And Human Harms Of Animal Experimentation, Aysha Akhtar
Experimentation Collection
Nonhuman animal (“animal”) experimentation is typically defended by arguments that it is reliable, that animals provide sufficiently good models of human biology and diseases to yield relevant information, and that, consequently, its use provides major human health benefits. I demonstrate that a growing body of scientific literature critically assessing the validity of animal experimentation generally (and animal modeling specifically) raises important concerns about its reliability and predictive value for human outcomes and for understanding human physiology. The unreliability of animal experimentation across a wide range of areas undermines scientific arguments in favor of the practice. Additionally, I show how animal …

Expression Of Emotional Arousal In Two Different Piglet Call Types, Linhart Pavel, Victoria F. Ratcliffe, David Reby, Marek Špinka
Bioacoustics Collection
Humans as well as many animal species reveal their emotional state in their voice. Vocal features show strikingly similar correlation patterns with emotional states across mammalian species, suggesting that the vocal expression of emotion follows highly conserved signalling rules. To fully understand the principles of emotional signalling in mammals it is, however, necessary to also account for any inconsistencies in the way that they are acoustically encoded. Here we investigate whether the expression of emotions differs between call types produced by the same species. We compare the acoustic structure of two common piglet calls—the scream (a distress call) and the …
