Lessons From Chimpanzee-Based Research On Human Disease: The Implications Of Genetic Differences, Jarrod Bailey
Laboratory Experiments Collection
Assertions that the use of chimpanzees to investigate human diseases is valid scientifically are frequently based on a reported 98–99% genetic similarity between the species. Critical analyses of the relevance of chimpanzee studies to human biology, however, indicate that this genetic similarity does not result in sufficient physiological similarity for the chimpanzee to constitute a good model for research, and furthermore, that chimpanzee data do not translate well to progress in clinical practice for humans. Leading examples include the minimal citations of chimpanzee research that is relevant to human medicine, the highly different pathology of HIV/AIDS and hepatitis C virus …

Learned Recognition And Avoidance Of Invasive Mosquitofish By The Shrimp, Paratya Australiensis, Joshua D. Bool, Kristen Whitcomb, Erin Kydd, Culum Brown
Sentience Collection
Little is known about the learning ability of crustaceans, especially with respect to their anti-predator responses to invasive species. In many vertebrates, anti-predator behaviour is influenced by experience during ontogeny. Here, predator-naïve glass shrimp (Paratya australiensisis) were exposed to a predatory, invasive fish species, Gambusia holbrooki, to determine whether shrimp could learn to: (1) avoid the scent of Gambusia via classical conditioning; and (2) restrict their activity patterns to the night to reduce predatory encounters. Conditioned shrimp were placed in containers in aquaria containing Gambusia for 3 days during which time they could be harassed but not consumed by Gambusia. …

The Evolution Of Lateralized Foot Use In Parrots: A Phylogenetic Approach, Culum Brown, Maria Magat
Sentience Collection
Cerebral lateralization refers to the division of cognitive function in either brain hemisphere and may be overtly expressed as behavioral asymmetries, such as handedness. The evolutionary history of laterality is of considerable interest due to its close link with the development of human language. Although considerable research effort has aimed at the proximate explanations of cerebral lateralization, considerably less attention has been paid to ultimate explanations. The extent to which laterality is constrained by phylogeny or shaped by ecological forces through natural selection has received little attention. Here, the foot preference of 23 species of Australian parrots was examined to …

People affect animals through four broad types of activity: (1) people keep companion, farm, laboratory and captive wild animals, often while using them for some purpose; (2) people cause deliberate harm to animals through activities such as slaughter, pest control, hunting, and toxicology testing; (3) people cause direct but unintended harm to animals through crop production, transportation, night-time lighting, and many other human activities; and (4) people harm animals indirectly by disturbing ecological systems and the processes of nature, for example by destroying habitat, introducing foreign species, and causing pollution and climate change. Each type of activity affects vast numbers …

Transgenesis In Animal Agriculture: Addressing Animal Health And Welfare Concerns, Michael Greger
Transgenesis Collection
The US Food and Drug Administration’s final Guidance for Industry on the regulation of transgenesis in animal agriculture has paved the way for the commercialization of genetically engineered (GE) farm animals. The production-related diseases associated with extant breeding technologies are reviewed, as well as the predictable welfare consequences of continued emphasis on prolificacy at the potential expense of physical fitness. Areas in which biotechnology could be used to improve the welfare of animals while maintaining profitability are explored along with regulatory schema to improve agency integration in GE animal oversight.

Aggression And Welfare In A Common Aquarium Fish, The Midas Cichlid, Ronald G. Oldfield
Faculty Scholarship
Many species of fishes are aggressive when placed in small aquaria. Aggression can negatively affect the welfare of those individuals toward whom it is directed. Animals may behave aggressively in order to defend resources such as food, shelter, mates, and offspring. The decision to defend depends on the distribution of resources and on ecological factors such as number of competitors, amount of available space, and amount of habitat complexity. This study tested the effects of these factors on aggression in a common aquarium fish, the Midas cichlid (Amphilophus citrinellus). The study found that time spent behaving aggressively was not associated …

Towards A New Paradigm Of Non-Captive Research On Cetacean Cognition, Lori Marino, Toni Frohoff
Experimentation Collection
Contemporary knowledge of impressive neurophysiology and behavior in cetaceans, combined with increasing opportunities for studying free-ranging cetaceans who initiate sociable interaction with humans, are converging to highlight serious ethical considerations and emerging opportunities for a new era of progressive and less-invasive cetacean research. Most research on cetacean cognition has taken place in controlled captive settings, e.g., research labs, marine parks. While these environments afford a certain amount of experimental rigor and logistical control they are fraught with limitations in external validity, impose tremendous stress on the part of the captive animals, and place burdens on populations from which they are …

Ethical And Scientific Considerations Regarding Animal Testing And Research, Hope Ferdowsian, Nancy Beck
Experimentation Collection
In 1959, William Russell and Rex Burch published the seminal book, The Principles of Humane Experimental Technique, which emphasized reduction, refinement, and replacement of animal use, principles which have since been referred to as the ‘‘3 Rs’’. These principles encouraged researchers to work to reduce the number of animals used in experiments to the minimum considered necessary, refine or limit the pain and distress to which animals are exposed, and replace the use of animals with non-animal alternatives when possible. Despite the attention brought to this issue by Russell and Burch and since, the number of animals used in research …

Indicators Of Age, Body Size And Sex In Goat Kid Calls Revealed Using The Source–Filter Theory, Elodie F. Briefer, Alan G. Mcelligott
Sentience Collection
The source–filter theory is an important framework recently applied to the study of animal vocalisations, which links the mode of vocal production to call parameters. Vocalisations can be good indicators of a sender’s characteristics, such as identity, body size, age, and even hormonal status and affective states. For these reasons, applied vocal communication research would greatly benefit from adopting the source–filter theory approach to identify key call parameters linked to physical and physiological characteristics of domestic animals. Here, we introduce the source–filter theory through a detailed analysis and interpretation of goat contact calls during development. In mammals, vocal development is …

The Effects Of Acute And Chronic Hypoxia On Cortisol, Glucose And Lactate Concentrations In Different Populations Of Three-Spined Stickleback, E. A. O'Connor, T. G. Pottinger, L. U. Sneddon
Aquaculture Collection
The response of individuals from three different populations of three-spined sticklebacks to acute and chronic periods of hypoxia (4.4 kPa DO, 2.2 mg l-1) were tested using measures of whole-body (WB) cortisol, glucose and lactate. Although there was no evidence of a neuroendocrine stress response to acute hypoxia, fish from the population least likely to experience hypoxia in their native habitat had the largest response to low oxygen, with significant evidence of anaerobic glycolysis after two hours of hypoxia. However, there was no measurable effect of a more prolonged period (seven days) of hypoxia on any of the fish in …

The Efficacy Of Three Types Of Analgesic Drugs In Reducing Pain In The Rainbow Trout, Oncorhynchus Mykiss, Jessica J. Mettam, Lois J. Oulton, Catherine R. Mccrohan, Lynne U. Sneddon
Veterinary Science and Medicine Collection
Recent research has shown the possibility of pain perception in fish; therefore, the use of analgesia or “painkillers” should be considered for invasive procedures. However, there is relatively little information on the effectiveness of analgesic drugs nor on the appropriate dose for fish. This study assessed the efficacy of three types of drug: an opioid, buprenorphine, a non-steroidal anti-inflammatory drug (NSAID), carprofen and a local anaesthetic, lidocaine. Each drug was tested at three doses on rainbow trout that were noxiously stimulated and the most effective dose was also given to fish experiencing no pain to investigate side-effects. Ventilation rate and …

Cerebral Lateralization Determines Hand Preferences In Australian Parrots, Culum Brown, Maria Magat
Sentience Collection
Individual preference for the use of one limb over the other to explore the environment or manipulate objects is common trait among vertebrates. Here, we explore the hypothesis that limb preference is determined by the engagement of a particular cerebral hemisphere to analyse certain stimuli. We recorded the eye and foot preferences of 322 individuals from 16 species of Australian parrots while investigating potential food items. Across all species, eye preferences explained 99 per cent of the variation in foot use in Australian parrots. The vast majority of species showed significant relationships between eye and foot preferences at the population …

Studies of causal understanding of tool relationships in captive chimpanzees have yielded disparate findings, particularly those reported by Povinelli & colleagues (2000) for tool tasks by laboratory chimpanzees. The present set of experiments tested nine enculturated chimpanzees on three versions of a support task, as described by Povinelli (2000), during which food rewards were presented in different experimental configurations. In Experiment 1, stimulus pairs included a choice between a cloth with a reward on the upper right corner or with a second reward off the cloth, adjacent to a corner, with the second pair comprised of a cloth with food …
