Individual Acoustic Variation In Fallow Deer (Dama Dama) Common And Harsh Groans: A Source-Filter Theory Perspective, Elisabetta Vannoni, Alan G. Mcelligott Mar 2007

Individual Acoustic Variation In Fallow Deer (Dama Dama) Common And Harsh Groans: A Source-Filter Theory Perspective, Elisabetta Vannoni, Alan G. Mcelligott

Veterinary Science and Medicine Collection

Mammals are able to distinguish conspecifics based on vocal cues, and the acoustic structure of mammal vocalizations is directly affected by the anatomy and action of the vocal apparatus. However, most studies investigating individual patterns in acoustic signals do not consider a vocal production-based perspective. In this study, we used the source-filter model of vocal production as a basis for investigating the acoustic variability of fallow deer groans. Using this approach, we quantified the potential of each acoustic component to carry information about individual identity. We also investigated if cues to individual identity carry over among the two groan types …


Plasticity In Animal Personality Traits: Does Prior Experience Alter The Degree Of Boldness?, Ashley J. Frost, Alexandra Winrow-Giffen, Paul J. Ashley, Lynne U. Sneddon Feb 2007

Plasticity In Animal Personality Traits: Does Prior Experience Alter The Degree Of Boldness?, Ashley J. Frost, Alexandra Winrow-Giffen, Paul J. Ashley, Lynne U. Sneddon

Ethology Collection

Theoreticians predict that animal ‘personality’ traits may be maladaptive if fixed throughout different contexts, so the present study aimed to test whether these traits are fixed or plastic. Rainbow trout (Onchorhyncus mykiss) were given emboldening or negative experiences in the forms of watching bold or shy individuals responding to novelty or winning or losing fights to examine whether prior experience affected boldness. Bold individuals that lost fights or watched shy demonstrators became more shy by increasing their latency to approach a novel object, whereas shy observers that watched bold demonstrators remained cautious and did not modify their responses to novelty. …


Maintenance Of Visual Stability In The Human Posterior Parietal Cortex, Erik Chang, Tony Ro Feb 2007

Maintenance Of Visual Stability In The Human Posterior Parietal Cortex, Erik Chang, Tony Ro

Publications and Research

Visual stability refers to our stable visuospatial perceptions despite the unstable visual input caused by saccades. Functional neuroimaging results, studies on patients with posterior parietal cortex (PPC) lesions, and single-unit recordings in the lateral intraparietal sulcus of primates indirectly suggest that the PPC might be a potential locus of visual stability through its involvement with spatial remapping. Here we directly explored the role of the PPC in visual stability by applying transcranial magnetic stimulation (TMS) while participants performed a perisaccadic displacement detection task. We show that TMS over the PPC but not a frontal control site alters sensitivity to displacement …

How Animals Communicate Quality Of Life: The Qualitative Assessment Of Behaviour, F. Wemelsfelder Jan 2007

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

Sentience Collection

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 …


Grey Parrots Do Not Always ‘Parrot’: The Roles Of Imitation And Phonological Awareness In The Creation Of New Labels From Existing Vocalizations, Irene M. Pepperberg Jan 2007

Grey Parrots Do Not Always ‘Parrot’: The Roles Of Imitation And Phonological Awareness In The Creation Of New Labels From Existing Vocalizations, Irene M. Pepperberg

Sentience Collection

Evidence exists for a form of imitation, vocal segmentation, by a Grey parrot. Data show that the bird understands that his labels are comprised of individual units that can be recombined in novel ways to create a novel referential vocalization; that is, a novel act. Previous data suggested, but could not substantiate, this behaviour. Such evidence implies that a parrot not only has phonological awareness but also demonstrates true imitation rather than mimicry, and has implications for the studies of both the evolution of communicative competence and the development of robotic speech.


Aquatic Animals, Cognitive Ethology, And Ethics: Questions About Sentience And Other Troubling Issues That Lurk In Turbid Water, Marc Bekoff Jan 2007

Aquatic Animals, Cognitive Ethology, And Ethics: Questions About Sentience And Other Troubling Issues That Lurk In Turbid Water, Marc Bekoff

Sentience Collection

In this general, strongly pro-animal, and somewhat utopian and personal essay, I argue that we owe aquatic animals respect and moral consideration just as we owe respect and moral consideration to all other animal beings, regardless of the taxonomic group to which they belong. In many ways it is more difficult to convince some people of our ethical obligations to numerous aquatic animals because we do not identify or empathize with them as we do with animals with whom we are more familiar or to whom we are more closely related, including those species (usually terrestrial) to whom we refer …

Does Increasing Biology Teacher Knowledge Of Evolution And The Nature Of Science Lead To Greater Advocacy For The Teaching Of Evolution In Schools?, Ross Nehm, Irvin Sam Schonfeld Jan 2007

Does Increasing Biology Teacher Knowledge Of Evolution And The Nature Of Science Lead To Greater Advocacy For The Teaching Of Evolution In Schools?, Ross Nehm, Irvin Sam Schonfeld

Publications and Research

This study investigated whether or not an increase in secondary science teacher knowledge about evolution and the nature of science gained from completing a graduate-level evolution course was associated with greater preference for the teaching of evolution in schools. Forty-four precertified secondary biology teachers participated in a 14-week intervention designed to address documented misconceptions identified by a precourse instrument. The course produced statistically significant gains in teacher knowledge of evolution and the nature of science and a significant decrease in misconceptions about evolution and natural selection. Nevertheless, teachers' postcourse preference positions remained unchanged; the majority of science teachers still preferred …

Sex Differences In The Onset Of Seasonal Reproductive Quiescence In Hamsters, Annaliese K. Beery, Justin J. Trumbull, Jyeming M. Tsao, Ruth M. Costantini, Irving Zucker Jan 2007

Sex Differences In The Onset Of Seasonal Reproductive Quiescence In Hamsters, Annaliese K. Beery, Justin J. Trumbull, Jyeming M. Tsao, Ruth M. Costantini, Irving Zucker

Neuroscience: Faculty Publications

Day length is the primary cue used by many mammals to restrict reproduction to favourable spring and summer months, but it is unknown for any mammal whether the seasonal loss of fertility begins at the same time and occurs at the same rate in females and males; nor it established whether the termination of mating behaviour in males and females coincides with the loss of fertility. We speculated that females, owing to their greater energetic investment in reproduction, are the limiting sex in terminating offspring production in short days (SDs). Oestrous cycles and production of young were monitored in Syrian …


Observations Of Rough-Toothed Dolphins (Steno Bredanensis) Off The Coast Of Utila, Honduras, Stan A. Kuczaj Ii, Deirdre Yeater Jan 2007

Observations Of Rough-Toothed Dolphins (Steno Bredanensis) Off The Coast Of Utila, Honduras, Stan A. Kuczaj Ii, Deirdre Yeater

Psychology Faculty Publications

Local dive shop operators and fishermen report that rough-toothed dolphins (Steno bredanensis) are frequently encountered off the coast of Utila, Honduras, (16°05'46.5"N 86°55'47.8"W). Our observations suggest that at least some of these animals may constitute a resident population, although the extent of the resident group’s home range has not been determined. Twenty-eight rough-toothed dolphins were identified using photoidentification techniques, 15 of which were re-sighted on two or more occasions. The 12 animals that were re-sighted four or more times were typically seen together, suggesting that they constitute a stable social group. At least one of these dolphins is …


Aged Rats: Sex Differences And Responses To Chronic Stress, Rachel E. Bowman, Neil J. Maclusky, Samantha Diaz-Weinstein, Mark C. Zrull, Victoria N. Luine Dec 2006

Aged Rats: Sex Differences And Responses To Chronic Stress, Rachel E. Bowman, Neil J. Maclusky, Samantha Diaz-Weinstein, Mark C. Zrull, Victoria N. Luine

Psychology Faculty Publications

Cognitive, as well as physiological, sex differences exist in young adult rats under both basal conditions and following chronic stress; however, few studies have examined whether sex differences remain in aged subjects and whether responses to stress are altered. We compared aged male and female Fischer 344 rats (21.5 months at testing) without stress and when given 21 days of restraint for 6 h/day on locomotion, anxiety-related behaviors, object recognition (non-spatial memory), object placement (spatial memory), body weight and serum steroid hormone levels. Control (unstressed) females had lower levels of estradiol and testosterone and higher corticosterone than males, and stress …


Comparative Perspectives On The Functions Of Sleep, John A. Lesku Dec 2006

Comparative Perspectives On The Functions Of Sleep, John A. Lesku

All-Inclusive List of Electronic Theses and Dissertations

Previous comparative studies of sleep identified relationships between sleep and constitutive and ecological variables. Results from these studies helped shape early hypotheses for the function of sleep; however, all were conducted without an explicit phylogenetic or theoretic framework and focused exclusively on mammals. Hence, the validity of their results and applicability to other taxa is unclear. We ( 1) reviewed the literature on sleep in animals, (2) updated and reanalyzed the mammalian dataset using independent contrasts and (3) multivariate path analysis, and ( 4) presented the first quantitative analysis of sleep in a non-mammalian taxon: birds. Following previous mammalian analyses, …
