▼ In order to adapt their behaviour optimally and to be able to increase fitness, individuals are assumed to respond flexibly to environmental variation they encounter. Contrasting with this classical behavioural ecological point of view is the concept of animal personality. The latter focuses on understanding the mechanisms underlying and evolutionary processes maintaining variation in the expression of a behavioural trait over time and across situations or contexts. Originating in human psychology, personality studies have recently been integrated into the fields of ecology and evolution. Studies on consistent variation in behaviour within and between individuals (personality) have resulted in numerous insights and these are still expanding.
In the first chapter of this thesis I research underlying factors and possible consequences of the response (delayed hatching) of blue tits (Cyanistes caeruleus) to encountered climatic variation. I find that hatching delay (i.e. number of days hatching was delayed) is associated with early laying dates and low mean temperatures during the egg-laying phase. In addition hatching delay is negatively associated with clutch hatchability and female body condition. Using a reciprocal cross-fostering protocol on a large number of broods, I find that hatching delay may also negatively affect developmental parameters in offspring, in particular body mass of nestlings at fledging. Results from this study demonstrate that environmental conditions during egg laying can have effects lasting throughout the breeding and nestling period.
In chapters II to V I investigate variation in behaviour among individuals. The focus in these four chapters is on personality traits in blue tits. I first design an experimental setup, using a bird cage, in which several behavioural traits can be measured in a quick and non-invasive manner and which can be applied in both winter and breeding season. In addition several behavioural traits are measured during handling of both adult and nestling birds. All these behavioural measures are then used to test several aspects of behaviour in a personality context in the blue tit. The behavioural traits derived from the bird cage are repeatable over time and qualify as personality traits in this species. In addition I find an association between one of the measured personality traits in the cage and a single nucleotide polymorphism in the 3rd exon of the dopamine receptor (D4) gene (DRD4), similar to what has been found in recent research on great tits (Parus major). This suggests that there is a genetic basis underlying this personality trait and that this genomic region might be involved in animal personality.
I apply a reaction norm framework to assess context specificity of the traits measured in the bird cage, using measures from (partly) the same birds measured in two distinct contexts (winter and breeding season). I show that one needs to carefully consider the context under which individuals are assayed and that a recorded behaviour may or may not be…

▼ This thesis aimed to provide evidence-based recommendations for improving cat welfare during handling. First, a cat handling questionnaire suggests that veterinarians (n=344) and non-veterinarian staff (n=944), commonly use restraint involving immobilization for examinations and procedures when handling fearful and aggressive cats. Participants were less likely to use full-body with scruff restraint (known negative) on fearful (F) and aggressive (A) cats if they work: at a Cat-Friendly Practice (F: P=0.0001; A: P=0.0001), in Canada (F: P<0.0001; A: ns), as a veterinarian (F: P<0.0001; A: ns), or as a non-veterinarian who graduated in 2005 or earlier (F: P<0.0001; A: P<0.0001). Given a lack of scientific evidence to inform good handling, methodologies were validated to assess cat responses to handling by comparing full-body (known negative) and passive (control) restraint. Cats were categorized as friendly or unfriendly based on interactions with a stranger, given the hypothesis that unfriendly cats would display more avoidance behaviours than friendly cats. Conditioned place aversion (CPA) was validated for use with laboratory (n=10) and friendly shelter (n=26) cats, using a two-compartment apparatus; cats showed aversion towards the compartment where full-body restraint occurred (P=0.043; P=0.035). Shelter cats were used to validate behavioural and physiological response differences between passive (n=22) and full-body (n=25) restraint. Full-body restrained cats showed a higher respiratory rate (P=0.004), more lip licks (F1,42 = 6.18; P = 0.017), more side/back ear positions (P<0.0001), and a greater pupil dilation (unfriendly full-body vs unfriendly passive, P=0.0007), than passively restrained cats. These responses were then used to assess cat responses to scruff (n=17), clip (two clips applied to neck skin; n=16), and full-body (negative; n=19), compared to passive restraint. The number of negative responses were highest in full-body (respiratory rate P=0.01; ear P=0.0007, pupil P=0.004, vocalizations P=0.005) and clip (pupil P=0.01, vocalizations P=0.007, ear P=0.02) restrained cats. The results for scruffed cats showed mixed results in comparison to the other restraint groups. This thesis provides the first validated methodologies to assess cat responses to restraint, and suggests that clip restraint may be more negative to scruff restraint, showing a need for further research on alternatives.

▼ Mate choice, a complex searching and
decision-making process, is relatively understudied. I explore the
process of mate choice in lekking long-tailed manakins
(Chiroxiphia linearis) using video
recordings to determine male quality, and a novel radiotracking
system to monitor female search behaviour. I report how females may
play an important role in the evolution of cooperative display
through their choices and behaviours during courtship. I show that
females are more likely to copulate at leks with higher attendance
and display effort, and more cooperative dance manoeuvres. I also
characterize the complex mate searching strategies employed by
females. I show that females visit an average of
4.02±0.42 leks when assessing mates, and also revisit
higher quality leks multiple times. Overall, my thesis provides
insight into mate choice in long-tailed manakins, revealing that
females make complex decisions that have important fitness
consequences, and that females may also influence the courtship
behaviours of males.

▼ Spatial memory is important for animals to
achieve successful foraging in structurally complex habitats.
Animals use consistent patch location as a reference to locate
food. To use objects as navigational landmarks, animals must encode
the specific spatial location and non-spatial features of the
location of hidden food within their working memory. How animals
use both the spatial and non-spatial aspects of landmarks and
beacons is a major theoretical question in the study of their
cognitive processes. The two objectives of this thesis were to
determine whether spatial encoding is absolute or relative and how
much of the spatial and non-spatial information is encoded. Also,
we expanded Brodbeck's (1994) method for investigating
multi-dimensional cue preferences. Results showed the flexibility
of rat's visuo-spatial working memory. The baseline results
obtained from my study will be helpful in conducting comparative
studies on working memory across species and to study various
disease models affecting working memory.

▼ We sometimes fail to notice objects and events in our environment because our attention is directed elsewhere—a phenomenon
called inattentional blindness. Our attentional set—the features we prioritize in our environment—plays a large role in determining what
we notice. For example, adopting an attentional set for green makes green objects more likely to capture attention. Although a large body
of research has explored the types of attentional sets we may adopt, few have explored the time course of attentional sets. And, out of
these, none have explored how experience with a no-longer useful attentional set can impact the activation of new attentional sets. In two
experiments, I show that a minimal amount of experience with an attentional set can cause that set to remain active past the point when it
is no longer useful: Noticing of an unexpected object was higher when its color matched the color of previous targets, but new
distractors, than when its color matched the color of objects that were always distractors. Furthermore, noticing was equivalent between
times when the unexpected object's color matched the color of objects that were previous distractors, but new targets, and times when its
color matched the color of objects that were always targets. Overall, this finding suggests that past experience with an attentional set
can impact the time it takes to adopt a new attentional set.

▼ The ability to measure travel distances is central to navigating by path integration. A path integrating animal constantly and automatically sums movement vectors containing distance and direction self-motion information, providing it with a global vector home to a starting position. This allows the animal to at any time compute novel shortcuts through its familiar area, and reduces the reliance on external positional information to navigate. Distance estimation has been widely documented in terrestrial animals at the sensory and neural mechanistic levels. In contrast, nothing is known about how freely-swimming aquatic animals such as the large vertebrate group - the teleost fish - collect and compute information on distance travelled. Understanding odometry in teleost fish is important first, for understanding the evolution of vertebrate spatial cognition from an aquatic common ancestor, and second, for understanding how aquatic animals more generally collect metric spatial information under the constraints and challenges of navigating underwater. In this thesis, I study distance estimation in teleost fish for the first time. Using the Picasso triggerfish, Rhinecanthus aculeatus, I aim to answer two key questions: (i) Can teleost fish estimate distance travelled, and with what accuracy? (ii) What sensory mechanisms do teleost fish use to estimate distance travelled? Using an operant conditioning task, I show that teleost fish can learn and remember travel distances with remarkable accuracy. This internal representation of distance travelled is also preferentially used over previously learned landmark cues when the two sources of information are in conflict. I proceed to explore the sensory mechanisms underlying distance estimation in Rhinecanthus aculeatus. I show that Rhinecanthus is unlikely to use mechanosensory inputs from finbeats or measures of travel time for odometry. However, like many terrestrial animals, Rhinecanthus aculeatus relies strongly on self-induced optic flow to reproduce travel distances. Visual motion information is also used more broadly to control swimming speeds and to maintain straight, stable swimming trajectories. Therefore, despite the physical constraints water places on the scope of such sensory information, visual motion information can be as important for navigating underwater as it is on land. Unlike many terrestrial animals, teleost fish also have access to a second frame of reference from which they can measure travel distances: the water through which they swim. I finish by presenting preliminary evidence suggesting that in the absence of visual information Rhinecanthus can use sensory information from the water column itself to measure relative distance travelled. This work provides an important baseline for understanding the mechanisms underlying distance estimation in teleost fish. Using the operant conditioning task developed in this thesis, we can study the neural basis of the teleost odometer and continue to test hypotheses about how metric spatial information is collected…

▼ Depression affects approximately 7% of adults in the US annually and is one of the most common mental disorders. One striking
aspect of this disorder, is that it affects women at about twice the rate as compared to men. Furthermore, women with cardiovascular
diseases are more likely to experience depression as compared to male counterparts. Thus, women with cardiovascular complications
represent an extremely vulnerable population for mood disorder. Given the disparity in depression prevalence, it is not surprising that
women are also more likely to take antidepressant treatments as compared to men. While the dose of the antidepressant prescribed is
similar across the board, there is mounting evidence that the efficacy of and sensitivity to these treatments differ between the sexes.
However, the majority of preclinical investigations into the effectiveness and biochemical mechanisms of antidepressants have been
conducted in male subjects. This is a serious gap in our knowledge, and investigations into the mechanisms underlying differences in
depression prevalence and antidepressant response is imperative. As such, this dissertation aimed to identify potential peripheral and
neural changes associated with onset of depression in females with cardiovascular disease, and to examine the neural mechanisms underlying
the sex differences in sensitivity to antidepressants. There is substantial evidence that depression is experienced at a much higher rate
in individuals with chronic conditions, such as cardiovascular disease. Within this population, women with cardiovascular diseases
represent an extremely vulnerable population for mood disorder, comorbid for these conditions at about twice the rate as compared to men.
Despite the well-established comorbidity, the mechanisms linking these disorders remain elusive. The first chapter of this dissertation
aimed to identify the expression of core behavioral features of mood disorder in female mice bearing a knock-in sarcomeric mutation, which
is exhibited in human hypertrophic cardiomyopathy (HCM). We then investigated peripheral physiological indicators of stress in these mice,
and discovered significant adrenal gland hypertrophy and a dominant sympathetic nervous system tone. Through the use of magnetic resonance
imaging, we found reduced volume in mood-related brain regions in females with HCM. We also observed significant reductions in hippocampal
neurotrophic signaling markers in females with HCM as compared to controls. These results suggest that prolonged systemic HCM stress is
central to mood disorder expression; possibly through induction of structural and functional brain changes. In direct contrast to the
negative impact of stress/depression on the structure and function of the brain, many antidepressants reverse these changes and…

▼ There has been an explosion in the use of experimental methods since the 1980s. This dissertation applies those experimental methods to various topics in public economics like tax evasion, crowding-out, labor supply, and cooperation. In chapter one I manipulate tax rates and whether students are capable of tax evasion in the laboratory. In joint provision settings, where public goods are provided through donations and tax revenues, these manipulations provide clean inference about the effects of tax evasion on crowding-out. Moreover, I collect measures of warm glow to estimate its relationship with contribution behavior across evasion settings. I find the usual crowding-out result when there is no tax evasion, however, I find complete crowding-out when tax evasion is possible. The collected measures of warm glow do not explain these results. The second chapter is co-authored with Robert White. In that chapter students complete real effort tasks in the laboratory for a piece-rate payment and we manipulate the shapes of these piece-rate earnings schedules. These shapes are intended to capture different features of the U.S. tax code when the loss of benefits (e.g. SNAP, WIC, Section 8 Housing, and Medicaid) are accounted for. We analyze how the shapes of these piece-rate schedules (as well as other behavioral factors (e.g. loss aversion, overconfidence, etc.) affect labor supply. We find that the piece-rate schedules that imitate ``notches" (or discontinuous jumps in the budget set) do reduce labor supply, however, this behavioral response to taxation is learned across rounds. Chapter three provides the first direct study of the ``restart effect" in public goods games. The restart effect is said to occur when there is an upward pulse in contributions to the public good following a stoppage in game play. I manipulate the language of the experimental instructions as well as the length of time prior to the stoppage in game play to search for facts about what supports the restart effect. I find that language in the instructions about when the stoppages occur promotes the restart effect. Finally, Chapter four presents evidence from a non-experimental project where data problems prevented useful findings about the relationship between competition and public service quality.

▼ In this dissertation, we create three theoretical models to answer questions raised by recent experiments that lie beyond the scope of current theory. In the landmark-effect model, we determine size, shape and location for a territory that is optimal in the sense of minimizing defense costs, when a given proportion of the boundary is landmarked and its primary benefit in terms of fitness is greater ease of detecting intruders across it. In the subjective-resource-value model, we develop a game-theoretic model based on the War-of-Attrition game. Our results confirm that allowing players to adapt their subjective resource value based on their experiences can generate strong winner effects with weak or even no loser effects, which is not predicted by other theoretical models. In the rearguard-action model, we develop two versions of a game-theoretic model with different hypotheses on the function of volatile chemical emissions in animal contests, and we compare their results with observations in experiments. The two hypotheses are whether volatile chemicals are released to prevent the winner of the current round of contest from translating its victory into permanent possession of a contested resource, or are used to prevent a winner from inflicting costs on a fleeing loser.

▼ Competition and cooperation with conspecifics affect the costs and benefits of group living and the evolution of social organization and mating systems. Understanding the role of competition - specifically intrasexual competition - in determining reproductive success thus informs models explaining the diverse types of social organization seen across animal species. The research presented in this dissertation combines molecular, demographic, and social behavior data to explore patterns of reproduction in a population of blue monkeys (Cercopithecus mitis stuhlmanni) in western Kenya.
Blue monkeys typically live in one-male/multi-female groups and resident males are presumed to have a reproductive advantage over non-resident "bachelors." I used fecal samples from 60 resident and bachelor males and 126 offspring born in 8 study groups over a 10-year period to quantify resident siring success. Residents sired at most 61% of offspring conceived in their groups, a percentage that is less than most other mammals living in one-male groups and may be linked to blue monkeys' unusually dynamic social organization. In the study population, some groups in some years experience influxes of competitor males; these influxes are most likely to occur in years when many females are mating simultaneously. I found a significant and negative effect of female reproductive synchrony and the number of male competitors on resident siring success. These results suggest that it is difficult for a resident male to defend access to multiple sexually receptive females, which may be further complicated by the presence of many competitors trying to steal matings. Resident male blue monkeys lost a substantial proportion of reproduction (39% of infants sired) to outside males, which challenges the presumed reproductive advantage of residency. Even though rival males are, by definition, less often nearby in one-male groups than in multi-male groups, they pose a competitive threat to resident male blue monkeys.
I used the paternity assignments to identify the factors affecting the siring success of extra-group males, including resident males in adjacent groups and bachelors. When a resident male was unable to monopolize reproduction in his own group, resident males in adjacent groups tended to be more likely to sire offspring than bachelors. Neither bachelor dominance rank nor time spent in a group was a significant predictor of siring success, suggesting that bachelor siring success may reflect a highly opportunistic mating tactic, which succeeds in a visually opaque habitat where estrous females, who mate rarely, are often widely dispersed.
Comparing the success of alternative reproductive tactics provides a more complete understanding of the evolution of mating systems. I used rates of resident and bachelor siring success and home range overlap to compute the number of years the hypothetical average bachelor would have to pursue the bachelor tactic to sire as many offspring as the hypothetical average resident during one or two…

▼ Social animals must overcome conflicts, an inherent and often detrimental consequence of gregarious life. One strategy for doing so is reconciliation, or post-conflict affiliation between former opponents. In humans and other primates, this behavior is often assumed to require a switch between opposing motivational states (e.g., anti- to pro-social). In this thesis, I argue that reconciliation is facilitated by an underlying individual tendency for movement and change between states, a motivation known as locomotion. Section one of this thesis uses a longitudinal, observational approach to establish stable individual differences in chimpanzee reconciliation while controlling for numerous relational factors known to influence the occurrence of this behavior. These individual differences are then related to several behavioral proxies of locomotion motivation. Section two of this thesis explores the relation between locomotion and conflict resolution in humans, using a range of methodological approaches and measures, including hypothetical scenarios, experimental inductions, essay studies, narrative reflections, and dyadic interactions. I conclude by emphasizing the importance of going beyond relational and other instrumental approaches to conflict resolution in order to understand more fundamental individual motivations underlying reconciliation behavior. If an individual motive to effect change and therefore resolve conflict in turn impacts one’s social relationships, it has even broader significance. Across the primate order, the influence and importance of such relationships suggest the potential role of reconciliatory motivations when it comes to individual survival, health, and overall well-being.

▼ Social interactions can have profound influences on an individual’s fitness. As part of a long-term research program on the mechanisms and functions of social behaviour in fruit flies (Drosophila melanogaster), we addressed two main questions. First, we asked whether social behaviour is positively correlated between the larval and adult stages. We quantified genetic variation in social behaviour by measuring aggregation among larvae and adults taken from each of 29 inbred, wild-derived lines. We found significant genetic variation in social behaviour in both larvae and adults. While these lines also showed significant genetic variation in baseline locomotor activity, it had no significant influence on social behaviour. We found that neither social behaviour nor activity were correlated between larval and adult flies. This is consistent with the hypothesis that metamorphosis adaptively decouples the expression of genes between distinct life stages in animals with complex life cycles. That is, genetic variation in social behaviour during each life stage may reflect adaptation to the specific ecological settings during that stage. Our second question was whether social behaviour in adult flies was influenced by indirect genetic effects (IGEs), defined as the effect an individual’s genotype has on the phenotype of an interacting partner. IGEs can have profound effects on the rate of phenotypic evolution. We found that groups of 6 focal males maintained shorter inter-individual distances among themselves when interacting with 12 males from a line previously identified as highly social than when paired with 12 males from the least social genotype. Overall, our results indicate that heritable genetic variation influences an individual’s predisposition to engage in social behaviour as well as its effect on social interactions among other individuals it encounters.

▼ This thesis measures consumer preference and willingness to pay for enhanced
animal welfare using eggs. In order to investigate consumer preferences for enhanced
animal welfare, two stated choice experiments are used to address consumers’ choices from eight combinations of enhanced
animal welfare attributes. Within each experiment, two treatments are applied to explore the role of additional information on consumer choices. A conditional logit model is employed to analyze data from a nation wide survey. In the first essay, the results show regional heterogeneity in Canadian consumer preferences for eggs from alternative housing systems. In the second essay, results show heterogeneity in consumer preferences for organizations that verify housing systems, using trust as the means of differentiating segments of consumer. The findings of the thesis provide information to the Canadian egg industry regarding the implications arising from improvement in hen welfare, and possible economic benefits arising from changes in hen housing

▼ This thesis explores the geometric description of animal colour vision. It examines the relationship of colour spaces to behavior and to physiology. I provide a derivation of, and explore the limits of, geometric spaces derived from the notion of risk and uncertainty aversion as well as the geometric objects that enumerate the variety of achievable colours. Using these principles I go on to explore evolutionary questions concerning colourfulness, such as aposematism, mimicry and the idea of aesthetic preference.

▼ Similarities in brain size, life histories, psychology and behaviour in parrots, corvids and apes suggest that certain socio-ecological selection pressures may have driven the convergent evolution of cognition in these families. However, very little is known about parrot behaviour and cognition, outside of African greys and kea. Therefore, captive red-shouldered macaws (Diopsittaca nobilis) and black-headed caiques (Pionites melanocephala) were presented with a variety of tasks to assess their social and physical cognition and behavioural flexibility. Although these species possess many similarities in their life history and ecology, there are also substantial differences in their morphology and natural habitats that could have driven differences in their cognitive evolution. Observations of social and physical interactions in both species revealed that macaws engaged in high levels of affiliative behaviour, and object neophobia, whereas caiques displayed high levels of social play and object exploration. However, such differences did not appear to result in differences in their social or physical cognition. Macaws and caiques displayed comparable performances on Serial Reversal Learning tasks (as an index of behavioural flexibility). Both species also demonstrated similar performances on two Means-End transfer tasks and a series of innovative foraging tasks that were designed to assess their comprehension of object relationships. However, macaws and caiques appeared to solve such problems by generalising learned information across novel tasks. Overall, these findings suggest that these two species may approach certain socio-ecological problems using flexible cognition that may be generalised across different problems, supporting claims for a domain general intelligence.

▼ Northern Botswana is one of the giraffe strongholds across its geographic range in the absence of, or with low impact from, the major anthropological threats faced elsewhere. Yet despite its conservation significance, until now, no giraffe-specific ecological or behavioural studies have been undertaken. Moreover, Africas giraffe population has been significantly reduced over the last two decades, and the pressure on giraffe habitats and populations is likely to increase as the human population continues to expand, and the effects of climate change take their toll. As such, it is important to establish an ecological and behavioural baseline for giraffe in the unique ecosystems. This study provides baseline data on the behaviour and ecology of giraffe in the dry savannah and woodlands of the northern Chobe region and the wetland system of the Okavango Delta (NG26) in northern Botswana. The study first examines the home ranges, seasonal ranges and daily movements of giraffe in the two study areas. Next, the focus is on giraffe behaviours and activity budgets, and the effect of site, sex, season and time of day on behaviour. Lastly, the study describes the giraffe social grouping patterns in Chobe and examines non-random associations and spatial overlap as possible factors driving the populations underlying fission-fusion system. Ecological and behavioural similarities were observed between the study areas, but also vast differences reflecting the adaptations made by giraffe in response to the unique set of environmental factors they face. Home ranges and daily movements were larger in Chobe where forage is more limited and patchily distributed, and ranges were larger during the dry season. Habitat, season, and sex were all found to be influential factors contributing to the observed variation in giraffe activity budgets. Social analyses revealed a complex social organisation whereby non-random associations and spatial overlap are drivers of a structured social network found within a fluid fission-fusion social system. Variation in pairwise association strengths and ranging patterns between the sexes suggest that males and females socialise differently. Association strength was generally greater for females than males though both sexes appeared to have preferred and avoided associates, indicating non-random groupings of individuals. Pairwise association strengths appear to be influenced more by social preferences and avoidances than spatial overlap, and shared space use has a greater influence over female social groupings.

▼ Very little is known about cattle vocalizations. The few studies available in the literature have been conducted using animals under stress or very intensive husbandry conditions. Similarly, the individual consistency of behaviour in cattle has rarely been considered except in applied studies of constrained and isolated animals, and no previous research has attempted to address a possible association between vocal communication and temperament in cattle. The studies reported here address these gaps in our knowledge. I found that cattle contact calls have acoustic characteristics that give them individualized distinctiveness, in both adult cows and calves. These results were confirmed using playback experiments, where I found that there is bidirectional mother-offspring recognition, as has been recorded in other “weak hider” ungulates. Additionally, using visual and acoustic stimuli, I assessed individual cattle temperament. The results showed that there was no individual behavioural consistency in responses to a novel object presentations. However, calves behaved consistently more boldly than cows. Furthermore, there was significant individual consistency in responses to vocalisations of heterospecifics, when they were played back through a speaker in the field. Surprisingly, no correlations were found between the ability of cattle to identify their own mother/offspring and the acoustic features of their vocalisations, or behavioural responses in any other context. There were, however, significant correlations between one characteristic of vocalisations in adult cows (formant spacing) and the boldness of behavioural responses to both novel objects and auditory stimuli. Additionally, higher F0 in calf contact vocalizations correlated with boldness in the auditory stimuli experiment. These relationships imply that vocalisations may encode information about individual temperament, something which has rarely been documented. Surprisingly, no strong correlations were found between the behavioural responses to visual and acoustic stimuli, suggesting that individual consistency in behaviour across contexts was limited, and that behavioural plasticity could play an important role in determining responses in different environmental contexts. Overall, my results contribute to our knowledge of animal communication in mammals from a bioacoustic point of view, and they are also potentially relevant to studies of vocalizations as indicators of cattle welfare.

▼ Abstract
Live animal encounter programs are an increasingly popular occurrence in the modern zoo. The welfare implications of animals participating in these programs has not been studied extensively to date. The aim of the current thesis was, therefore, to explore animal welfare effects associated with encounter programs in selected zoo-housed species, using a combined approach of survey data and empirical investigations.
The survey assessment, which involved over 500 accredited zoos and aquariums in Australia and overseas, revealed that most surveyed institutions (85 %) engaged in an encounter program with one or more species, most of which were mammals. Behaviours indicative of a typical fight-or-flight response were the most commonly reported welfare concerns in relation to encounters. Behaviour indicative of positive welfare, as well as voluntary participation and interaction with visitors, were commonly mentioned in regard to positive welfare during encounters. Positive welfare experiences outweighed the number of reported concerns in birds and mammals, but the opposite was true for reptiles.
The empirical studies involved zoo-housed servals, giraffes and shingleback lizards, and sought to identify a potential cause-effect relationship between behavioural and physiological welfare indices and short-term variations in encounter frequency. A similar methodology involving a repeated treatment design where the frequency of encounters was manipulated to reflect the regular frequency of encounters, a temporary withdrawal, and a temporary intensification of regime, was adopted across the three studies. Behavioural changes indicative of a positive welfare effect when participating in encounters were observed in the servals and giraffes. Servals exhibited a significant reduction in stereotypic pacing on weeks when participating in interactive presentations, or presentations and behind-the-scenes encounters combined. The giraffes engaged in amicable social interactions significantly more often when participating in visitor feeding encounters, at either regular or intensified frequency. By contrast, a potentially aversive effect of encounters was observed in the shinglebacks, who significantly increased their use of concealed locations within the enclosure when handled at either the regular or intensified frequency. Approach behaviour during encounters differed significantly between individual giraffes, and significant differences in coiling behaviour while handled was observed in the lizards.
The findings of the empirical studies were in agreement with the survey data, which identified taxonomic as well as individual variation as important influences on the welfare of animals participating in encounters. The nature of the encounter the animals participate in was identified as another key factor, in which encounters that maximise choice and control, and where animals are rewarded for participation, were likely to contribute to a more positive welfare experience.

▼ Male secondary sexual characteristics may convey information about the signaller. The red penis and blue scrotum of male vervet monkeys make them a good species to examine variation in signal expression. We quantified colour in vervets at Lake Nabugabo, Uganda from standardized photos. We hypothesized that inter- and intra-individual variation in the expression of the genital colour of males is influenced by parasites, dominance rank, age, androgens and glucocorticoids. Our results indicate that blue scrotal colour between males is predicted by rank and parasites, and red penis colour is predicted by age (or sexual maturity) and parasites. Within males, our findings indicate that short-term variation in blue scrotal colour characteristics and contrast are negatively correlated with measures of parasitism and red penis hue becomes redder (less pink) as males increase in rank. These findings support the Hamilton-Zuk hypothesis and suggest that vervet genitals are a badge of status symbol.

▼ Chapter 1: Illusions are commonplace and distort perception in ways that make objects appear different from reality. Such phenomena may also play a role in mate evaluation because body size and ornament size are signals shaped by sexual selection. Evolution of use of illusions through modifications of color patterns, environmental conditions, or behaviors may be common, yet are poorly understood. The Ebbinghaus illusion refers to the distorted perception of the size of an object depending on the size of surrounding objects, and is traditionally shown using Titchener circles. Because female sailfin mollies (Poecilia latipinna) choose mates from shoaling groups of males, I predicted that they would be susceptible to this illusion during mate selection. Specifically males surrounded by smaller Titchener circles (or conspecifics) should be preferred over those surrounded by larger circles (or conspecifics). I tested this prediction by presenting females with males at the center of an Ebbinghaus illusion, surrounded by Titchener circles, designed to make them appear either larger or smaller. I further tested this prediction using fish animations with focal male fish flanked by either larger or smaller males in shoaling groups. Females consistently chose the male flanked by smaller Titchener circles and this illusory effect endured when I replaced the Titchener circles with fish. Traditionally attractive larger males were not chosen, which is also consistent with predictions of the Ebbinghaus illusion. These results show that a male’s immediate environment can have a strong effect on generating a deceptive body-size perception to potential mates, and demonstrate that males have the potential to manipulate matings using the Ebbinghaus illusion.
Chapter 2: Identifying how signals can distort the receiver’s perception of reality is key to understanding signal evolution. Perceptual biases present in the receiver can create an inaccurate or incomplete perception of an environment, leading to sub-optimal decision-making. In some circumstances, signaling animals are able to deceive receivers by exploiting perceptual illusions, such as the Ebbinghaus illusion. Female sailfin mollies (Poecilia latipinna) have been shown to be susceptible to the Ebbinghaus illusion in a dichotomous choice experiment with contrasting illusions shown at the same time (Chapter 1). However, whether or not sailfin mollies remember the illusory effects while making mate choice decisions remains in question. Here, I tested whether this effect would persist over time using two experiments. In the first experiment I used live flanking males to induce the illusory effects. In the second experiment I used inanimate objects to mimic the Titchener circles found in the classic Ebbinghaus illusion. Specifically, I tested female preference for a male by sequentially presenting the same focal male with three different illusory contexts: 1) focal male flanked by smaller males or smaller inanimate objects, 2) focal male flanked by larger males or larger inanimate…

▼ Simple environmental features can shape complex
behavior. Identifying key
aspects of the environment (e.g., temperature, structure, toxins) that lead to widespread consequences is of central importance in a changing world. The primary objective of my dissertation is to investigate how relatively simple aspects of the environment can influence small groups of animals in profound and complex ways. In the first three chapters, I report on experiments showing how small changes in the environment can affect the expression of
behavior at different points in development and can have important physiological consequences for litters of mouse pups. I then report on two sets of experiments showing how subtle changes in the environment can dramatically affect spacing patterns and social dynamics of small groups of adult zebrafish. Together, my results emphasize the ways that subtle changes in the environment can have profound impacts on individuals and small groups. In both lines of work, I have found that a more accurate characterization of the phenomena, infant rodent development and zebrafish social
behavior, requires the use of individual and group measures and that temperature, density, and pollutants can have a powerful effect on group responses. These results are important because they show that the physical environment can have profound effects on the phenotype, and that with a changing physical environment or anthropogenic change, dramatic differences may be observed in the
behavior of groups.

▼ In this paper we introduce two different models to study the group dynamic of birds on wire and taking off the ground. To begin with, the first model is agent-based and encompasses attraction-repulsion forces and topological interactions. The model is firstly analyzed and then simulated to study the main properties. Then, we compare the achieved results with data from pictures taken in New Jersey. Two different image elaboration protocols allowed establishing a good agreement with the model. Moreover, we showed potential handiness by analyzing group organization features and dynamics of groups with landing new birds. To further complete the analysis we also introduced a birth-death process to include the modeling of landing and departing birds. Secondly, the second model inspired by videos of birds taking flight was created with options for two different methods that are metric and topological interactions. Furthermore, the model returns a graph displaying the number of birds in the air vs. the time that is very similar to the observed data that was analyzes via ImageJ. Comparing the topological and metric interaction, the topological method is less regular and has a longer front length. Lastly, many trends were observed when comparing the front velocities under various constraints.

▼ The objectives of this investigation were to examine the changes in vegetation resulting from application of herbicides, and to study the effects of these vegetative changes on the abundance and composition of small-mammal populations, and on deer usage of treated and untreated plots. Three areas in western Oregon were selected for study and half of each was treated with a combination of herbicides designed to control grasses and forbs without injuring Douglas-fir (Pseudotsuga menziesii (Mirb. ) franco). The effects of herbicide treatment were to eliminate or suppress grasses, control forbs, and to promote growth of shrubs and trees. Small mammals primarily associated with grass or meadow habitats decreased in abundance. The Oregon vole (Microtus oregoni) was the species most affected by the reduction in grassy vegetation. Species that find optimum habitat in brushy areas increased in abundance on treated plots. The deer mouse (Peromyscus
maniculatus) was the most common species to demonstrate a positive response on treated plots. The community response depended on the relative species composition. Deer activity, as measured by pellet-group counts, was greater on treated plots during the growing seasons. No significant differences were found in the occurrence of browsing as a result of herbicide-induced habitat changes. Browsing was influenced by season. Herbicide treatments improved deer habitat during the growing season without significantly increasing the browsing of Douglas-fir seedlings.

The Effect of Group Size on Individual Roles and the Potential for Cooperation in Group Bubble-net Feeding Humpback Whales (Megaptera novaeangliae).

▼ Group foraging is observed in many species as a means to increase the ability of members of the group to find and exploit patchy prey. Group foraging can be exhibited in a number of different contexts based on the relationships between the participants, including by-product mutualism. One variant of by-product mutualism is cooperation, in which individuals achieve a greater energetic gain by feeding together than they would alone. In cooperation, individuals adopt a role in the group, and in the most complex interactions there may be multiple roles, resulting in a division of labor that occasionally includes role specialization. Humpback whales (Megaptera novaeangliae) are one of the few baleen whale species that have been observed feeding in groups, utilizing behaviors that are hypothesized to be cooperative. One of these behaviors is group bubble-net feeding, which has been observed in the Northeastern Pacific, Northwestern Atlantic, and Southern Oceans. This study utilized multi-sensor archival tag data from 26 humpback whales from the southern Gulf of Maine, 4 from Southeast Alaska, and 1 from the Western Antarctic Peninsula to analyze individual bubble-net feeding behaviors and compare these across populations. Linear mixed effects models were used to determine if dive behaviors varied with group sizes to test the hypothesis that group size influences individual
behavior. The results indicate that individuals in the southern Gulf of Maine, for which sufficient data were available, were consistent in their bubble-net feeding behaviors across group sizes, which suggests that individuals utilize set roles in group feeding events. There was evidence for a division of labor and role specialization among whales utilizing certain bubble-net feeding tactics in the southern Gulf of Maine. The three populations performed different variations of bubble-net feeding that are likely based on the speed and schooling patterns of the prey. The results are consistent with the hypothesis that bubble-net feeding is an example of by-product mutualism in these populations, though was not enough data to suggest that group bubble-net feeding in Southeast Alaska was a form of by-product mutualism. The prevalence of herding dives in feeding groups suggest that each individual takes on a role to herd the prey to the surface, and provide evidence against a producer-scrounger relationship in the southern Gulf of Maine, and potentially in the Western Antarctic Peninsula.

▼ Predicting ewe maternal success and measuring maternal bond strength remain, to an extent, topics of mystery. The optimization of management strategies will always be an important goal for any livestock farmer. Optimizing maternal success at lambing time is an essential point of focus for any farmer hoping to profit from his or her flock of sheep. As more is understood about the behavioral tendencies related to maternal success, management systems will be tailored to lower labor requirements, making sheep farming less stressful for those involved and encouraging the growth of the sheep industry. Any tactic that can work toward the goals of decreased labor and increased production, while preserving or enhancing
animal welfare, should continue to be thoroughly explored. Allowing for and encouraging the natural expression of innate behaviors to achieve these goals, particularly including maternal
behavior, will remain an important area of focus in keeping sheep production viable.

▼ The purpose of this study was to investigate the existence of stigma related to mental health illnesses among music therapy
students at a large southeastern public university. A survey of nineteen stigma-related questions was designed and distributed to
seventy-six music therapy students. Forty-four surveys were collected (57.9%) and analyzed. The survey consisted of four demographic
questions and fifteen stigma related statements. Statements were related to one of three components of stigma: prejudice, stereotype, and
discrimination. Respondents answered each statement based on the extent to which they agreed or disagreed to each item on a five-point,
Likert-type scale. Results indicated that music therapy students tended to disagree with stigma-related statements. These results may
suggest a lower perceived stigma towards mental health illnesses among music therapy students. Understanding the prevalence of stigma on
mental health among music therapy students provides implications for future music therapists and current music therapists working in
mental or behavioral health settings to provide more adequate experiences for individuals with mental illness. Music therapists can help
challenge the stigma related to mental health, a major barrier for those wishing to seek treatment with mental illness.

▼ This study examined the influence of User Generated Branding (UGB) on consumers’ attitudes and purchase intentions by comparing it to brand generated advertising on the world’s largest social media website: Facebook (eMarketer, 2016). The research was theoretically grounded by the Theory of Planned
Behavior (TPB), which helped in understanding how consumers’ attitudes toward a
behavior would form their behavioral intentions. The advent of User Generated Branding on Facebook has radically changed the communication patterns between brands and consumers. Facebook, at its core, is a place for interpersonal communications. Therefore, it offers its members with emotional benefits through networking and conversations. But, as it is slowly evolving into a marketing platform (Scale, 2008), users have found many practical commercial implications in terms of information search on the platform before deciding to purchase an item. UGB refers to “the strategic and operative management of brand-related user generated content (UGC) by the brand and its consumers to achieve brand goals (Burmann & Arnhold, 2009, p. 3).” Brand-related user generated content is any type of data, information or media, voluntarily created and contributed by regular people who are consumers of a specific brand, which comes across as useful or entertaining to other consumers (Krumm et al., 2008). On the other hand, brand generated advertising is any form of media-related strategies and tactics, usually paid, deployed by a business in order to establish as well as maintain effective and ongoing communications with its customers (Stuhfaut & Davis, 2010). The current research tried to explore into this collaboration between consumers and brands as well as other consumers on Facebook (Saxena & Khanna, 2013). The present research posited that UGB, as an added consumer interaction touch point about brands on Facebook, could play a more decisive role than brand generated ads in shaping users’ perceptions, attitudes, and purchase intentions. 669 undergraduate students from a major university in Southeastern USA voluntarily participated in this research. In an online survey, the subjects were randomly assigned to one of the two experimental conditions, framed as either a UGB Facebook post or a brand generated ad post. Inattentive and inconsistent responses were eliminated using dummy test questions. So, the final sample size consisted of 539 participants (n = 539). The findings suggested that there was not a statistically significant difference in how these two sources of content impacted users’ attitudes and purchase intentions (p = .05). Both UGB posts and brand generated ads on Facebook were seen to play complementary roles in influencing consumers’ intentions to purchase. This research offered useful insights to marketers and advertisers in finding the right kind of content combination on Facebook that would induce favorable perceptions, attitudes and purchase intention. Practical implications showed that, on Facebook, brands should flexibly adapt their…
