Social Interaction, Social Cognition, And Personality In Gartersnakes And Ball Pythons, Morgan Skinner Jan 2024

Social Interaction, Social Cognition, And Personality In Gartersnakes And Ball Pythons, Morgan Skinner

Theses and Dissertations (Comprehensive)

Snakes are often considered non-social animals. However, this is mostly an untested assumption and the limited research that has been done has shown that snakes interact socially when given the opportunity. Here, the complexity of snake social interactions was explored through a social cognition and personality lens. Group and individual behavioural assays were used to explore flexibility and consistency in social interactions. The results provide evidence that elucidate the function, development, and evolution of these behaviours in snakes. In the first experimental chapter, chapter 2, social network analysis was used to provide a detailed description of aggregation behaviour in 4 …


Wild Animal Welfare, Clare Palmer, Peter Sandøe Jan 2022

Wild Animal Welfare, Clare Palmer, Peter Sandøe

Animal Sentience

Rowan et al’s article provides an overview of developments in the science of animal sentience and its links to animal welfare policy, especially regarding farm animals. But changing ideas of animal sentience and welfare are also important for managing wild and other free-living animals. We ask how the welfare of these animals differs from that of farmed animals, especially how the ability to make autonomous choices may matter. We suggest that more research into wild animal welfare is needed to make informed policy decisions, for example, about using animals in rewilding projects and choosing between policies of culling and fertility …


The Use Of Judgement Bias To Assess Welfare In Farm Livestock, L. Baciadonna, A. G. Mcelligott Nov 2017

The Use Of Judgement Bias To Assess Welfare In Farm Livestock, L. Baciadonna, A. G. Mcelligott

Alan G. McElligott, PhD

The development of accurate measures of animal emotions is important for improving and promoting animal welfare. Cognitive bias indicates the effect of emotional states on cognitive processes, such as memory, attention, and judgement. Cognitive bias tests complement existing behavioural and physiological measures for assessing the valence of animal emotions indirectly. The judgement bias test has been used to assess emotional states in non-human animals; mainly in laboratory settings. The aim of this review is to summarise the findings on the use of the judgement bias test approach in assessing emotions in non-human animals, focusing in particular on farm livestock. The …


Rescued Goats At A Sanctuary Display Positive Mood After Former Neglect, Elodie F. Briefer, Alan G. Mcelligott Sep 2016

Rescued Goats At A Sanctuary Display Positive Mood After Former Neglect, Elodie F. Briefer, Alan G. Mcelligott

Elodie Briefer, PhD

Moods influence cognitive processes in that people in positive moods expect more positive events to occur and less negative ones (“optimistic bias”), whereas the opposite happens for people in negative moods (“pessimistic bias”). The evidence for an effect of mood on cognitive bias is also increasing in animals, suggesting that measures of optimism and pessimism could provide useful indicators of animal welfare. For obvious ethical reasons, serious poor treatments cannot be easily replicated in large mammals in order to study their long-term effects on moods. In this study, we tested the long-term effects (>2 years) of prior poor welfare …


What Do We Owe Animals As Persons?, Judith Benz-Schwarzburg Aug 2016

What Do We Owe Animals As Persons?, Judith Benz-Schwarzburg

Animal Sentience

Rowlands (2016) concentrates strictly on the metaphysical concept of person, but his notion of animal personhood bears a moral dimension (Monsó, 2016). His definition of pre-reflective self-awareness has a focus on sentience and on the lived body of a person as well as on her implicit awareness of her own goals. Interestingly, these also play a key role in animal welfare science, as well as in animal rights theories that value the interests of animals. Thus, Rowlands’s concept shows connectivity with both major fields of animal ethics. His metaphysical arguments might indeed contain a strong answer to the question of …


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 …

How Animals Communicate Quality Of Life: The Qualitative Assessment Of Behaviour, F. Wemelsfelder Jun 2016

How Animals Communicate Quality Of Life: The Qualitative Assessment Of Behaviour, F. Wemelsfelder

Françoise Wemelsfelder, PhD

The notion ‘quality of life’ (QoL) suggests that welfare in animals encompasses more than just an absence of suffering; it concerns the quality of an animal’s entire relationship with its environment, of how it lives its life. Judgements of such quality are based on the integration of perceived details of how animals behave over time in different contexts. The scientific status of such judgements has long been ambiguous, but in recent decades has begun to be addressed by animal scientists. This paper starts with a brief review of qualitative approaches to the study of animal behaviour, which tend to address …


What’S The Common Sense Of Just Some Improvement Of Some Welfare For Some Animals?, Liv Baker Jan 2016

What’S The Common Sense Of Just Some Improvement Of Some Welfare For Some Animals?, Liv Baker

Animal Sentience

The goal of Animal Welfare Science to reduce animal suffering is commendable but too modest: Suffering animals need and deserve far more.


Animal Welfare And Animal Rights, M.E. Rolle Jan 2016

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.


Defining And Assessing Animal Pain, Lynne U. Sneddon, Robert W. Elwood, Shelley A. Adamo, Matthew C. Leach Jun 2015

Defining And Assessing Animal Pain, Lynne U. Sneddon, Robert W. Elwood, Shelley A. Adamo, Matthew C. Leach

Lynne Sneddon, PhD

The detection and assessment of pain in animals is crucial to improving their welfare in a variety of contexts in which humans are ethically or legally bound to do so. Thus clear standards to judge whether pain is likely to occur in any animal species is vital to inform whether to alleviate pain or to drive the refinement of procedures to reduce invasiveness, thereby minimizing pain. We define two key concepts that can be used to evaluate the potential for pain in both invertebrate and vertebrate taxa. First, responses to noxious, potentially painful events should affect neurobiology, physiology and behaviour …

Animal Pleasure And Its Moral Significance, Jonathan Balcombe Jun 2014

Animal Pleasure And Its Moral Significance, Jonathan Balcombe

Jonathan Balcombe, PhD

This paper presents arguments for, and evidence in support of, the important role of pleasure in animals’ lives, and outlines its considerable significance to humankind’s relationship to other animals. In the realms of animal sentience, almost all scholarly discussion revolves around its negative aspects: pain, stress, distress, and suffering. By contrast, the positive aspects of sentience – rewards and pleasures – have been rarely broached by scientists. Yet, evolutionary principles predict that animals, like humans, are motivated to seek rewards, and not merely to avoid pain and suffering. Natural selection favours behaviours that enhance survival and procreation. In the conscious, …

Science, Values And Animal Welfare: Exploring The ‘Inextricable Connection’, D. Fraser Jan 1995

Science, Values And Animal Welfare: Exploring The ‘Inextricable Connection’, D. Fraser

Animal Welfare Collection

In conceptualizing animal welfare, it is useful to distinguish among three types of concepts. 'Type l' are single, measurable attributes. 'Type 2' are single attributes that cannot be measured directly but can be estimated by correctly combining various contributing attributes. 'Type 3' are concepts involving multiple attributes which are grouped together because they serve some common function, and whose relative importance cannot be established in an entirely objective way. Individuals who treat animal welfare as a type 1 concept may propose single, objective measures of welfare, such as longevity or levels of stress-related hormones; however, this approach rests on judgements, …
