The Ape Ecological Niche: Posture and Hand Use in Gibbons and Macaques and the Influence of Manual Skill on Cognitive Development in Apes and Humans

Prime, Jacqueline Marie 01 May 2014 (has links)
Apes share a distinct set of morphological and anatomical characteristics that allow us to use our arms and hands in unique ways. Apes also have relatively larger brains with similar sulcal patterning indicating there is a distinctively hominoid brain structure. These features in great apes have consistently been linked with higher cognitive skills and are considered to be the precursors leading to the exceptional developments of humans over evolutionary time – establishing the physiological basis that allows us to make and use tools to modify our environments and build our unique cultures. This study examines the general model that orthogrady and suspensory postures were the antecedents for enhanced manipulative ability in apes, which consequently set the stage for enhanced cognitive abilities in early hominoids. The primary hypothesis is that if single-handed prehensility is enhanced by suspensory orthogrady, then we may predict ape feeding style will differ significantly from that of pronograde monkeys, allowing them to access foods in unique ways. Using sympatric white-handed gibbons, Hylobates lar, representative of orthograde apes, and pig-tailed macaques, Maccaca leonina, representative of pronograde monkeys, as models, the comparative feeding styles of primates were analyzed focusing on their positional behaviour and manual skill. Results support the hypothesis that gibbons exhibit a unique feeding style associated with their orthogrady/suspensory postures in comparison with pronograde macaques. This was demonstrated by their increased access to food in the trees with more stable postures, an expanded foraging radius, and more frequent use of the terminal branches, and was evident in their complex manipulative skills with larger manual repertoires, more variability in wrist use, and more sophisticated manual techniques. Moreover, significant differences in positional behaviour and manual skill demonstrated by gibbons and macaques were evident even when feeding on the same types of foods within their shared environment. This study proposes that the combined uniquely ape traits to forage in suspensory orthograde postures with precision dexterity have allowed apes to become highly selective feeders within their environments, leading to advance manual dexterity and cognitive prowess in apes.

Gibbon's Guides: The Scholarly Reception of Ammianus Marcellinus and Procopius of Caesarea After the Decline and Fall of the Roman Empire

Murtaugh, Sarah J 14 December 2012 (has links)
This thesis explores the influence of Edward Gibbon's History of the Decline and Fall of the Roman Empire on modern scholarship about two ancient Roman historians, Ammianus Marcellinus and Procopius of Caesarea. It reveals that Gibbon's way of thinking about these historians, whom he referred to as his "guides," continues to shape scholarly discourse about them.

ACOUSTIC TEMPORAL VARIATION, CALL ORDER, AND TRAVEL IN RESPONSE TO ANTHROPOGENIC NOISE IN WILD SIAMANG (SYMPHALANGUS SYNDACTYLUS)

D'Agostino, Justin 01 June 2021 (has links) (PDF)
Communication is a behavioral strategy used by species in the competition for survival and reproduction. Animals produce signals that are sent to receivers and occasionally transmit information that can be beneficial in a variety of contexts including avoiding predators, locating food resources, and maintaining the pair bond between partners. Researchers are interested in if auditory signals are variable and if the variability is biologically meaningful to receivers. Some species, such as siamang, sing duets as their form of acoustic communication and these duets have been studied for a variety of purposes such as investigating their structure, variability, and functionality. Siamang are a species of gibbon that combine a finite number of call units into structurally complex sequences in rule-governed ways, hereby conveying different contextual situations. Some wild gibbon species have demonstrated variation in the temporal structure of their duets and the distinctiveness in acoustic timing is unique enough for researchers to distinguish among individuals and groups based on their duet contributions. The process of coordinating and producing a uniquely timed duet could function in relation to the formation and maintenance of the pair bond. This dissertation analyzed the temporal variation and call order of wild siamang (Symphalangus syndactylus) duets that are comprised of four distinct sequences comprised of several note types. Previous research has provided detailed descriptions of captive siamang duets that include category descriptions of four call types: grunting, introduction, interlude, and great call. While these descriptions provide a general understanding of the structure of siamang duets, they can be confusing and difficult to study empirically due to their arbitrary nature. For instance, the siamang great call has been described as occurring in over 30 variants and in stable, or typical, and unstable, or atypical forms. The stable or typical form of the great call has been described to occur only after the male’s first bitonal scream. This previous research did not measure the timing of sequences through entire duets or conduct individual note analyses. Also, the most detailed investigations of siamang duets were conducted with captive animals and therefore wild siamang duets have not been quantitatively analyzed. This dissertation research measures the temporal variation of wild siamang duet call types, and the call order of individual notes in the US-II phrase. The findings will provide a more objective description of the siamang duet as well as determine if it has a more stereotyped or flexible nature. Also, in the wake of globalization, duets and other behaviors (such as travel) could be sensitive to anthropogenic disturbances. So, I am interested in how wild siamang might be impacted by human presence. The three main objectives of this dissertation are: 1) document the temporal variation in the call types of wild siamang; 2) document variation in the call order of wild siamang US-II phrases; and 3) document how wild siamang travel is impacted by anthropogenic noise. The study was conducted at 4 remote field sites in northern Sumatra, Indonesia from August 2017 through May 2018. With the assistance of a research team, I recorded acoustic and behavioral data from 10 siamang groups and two individual females. I collected acoustic data using a combination of autonomous recording units and handheld recording devices while following the study subjects on foot. I marked GPS points during behavioral scans and conducted experimentally induced noise playback experiments. I analyzed the audio data with the software program Raven Pro 1.6 and spectrograms were produced with a 512-point (11.6 ms) Hann window (3 dB bandwidth = 135 Hz), with 50% overlap and a 512-point DFT, yielding time and frequency measurement precision of 2.9 ms and 43.1 Hz. I conducted statistical testing in R Studio Version 1.3.959 in conjunction with the statistics lab at Southern Illinois University. In Chapter 3, I performed multilevel regression analysis in the form of a Generalized Linear Mixed Model (GLMM) in order to investigate temporal variation the time spent singing call types (grunting, introduction, interlude, and great call) accounting for differences between songs, groups, and field sites. I used a Bayesian hierarchical model to avoid calculating estimates using data with repeated and imbalanced sampling, and explicitly model variation within individuals, between songs, between groups, and field sites. In Chapter 4, I used the Levenshtein Distance (LD) method for investigating structural variation in the call order of US-II phrases in the siamang duet. The LD method is a quantitative technique for measuring the similarity of sequences and to quantify the differences between strings of data. In Chapter 5, I used the Friedman test to compare the means of distances traveled in 5-minute intervals in the following conditions: pre-playback, cicada (control), traffic, jackhammer, and music. I used post hoc tests with Bonferroni correction to analyze the pairwise comparisons of the five experimental conditions. Overall, the results suggest support of previous studies on the variability of the gibbon duet and animal travel in response to noise. In Chapter 3, I found some temporal variation in call types to exist at all levels of the modeling but only statistically significant when comparing the field sites of Ketambe and Kutapanjang. Relating to the functionality of total call duration, I did not find significant differences in the behavioral categories before or after any of the calls regardless of their total duration. In Chapter 4, I found US-II phrases are not as stereotyped as previous descriptions have suggested. The mean LD distances were higher than those compared by other duetting primates. Also, the results from one-way ANOVA and Games-Howell Post Hoc Testing showed significant mean differences between groups. In Chapter 5, I found siamang are impacted by noise as they traveled further after the anthropogenic noise playback experiments compared to pre-playback travel. However, the pairwise comparisons were not statistically significant and therefore I could not determine which noise condition caused the change in travel distance. Collectively, the results of this dissertation suggest that there is considerable variability in both wild siamang call types and call order in a previously described stereotyped phrase, and that wild siamang travel away is impacted by introduced anthropogenic noise. What this contributes to the field of vocalization studies is further support that precise measurement of song parameters gives a better understanding of song structure than somewhat arbitrary written descriptions. It is important to have descriptions of notes produced in songs, but to understand how those notes relate to each other, an individual note analysis and rigorous statistical methodology is necessary. The variation found in this dissertation could be due to the unique siamang response to their partner’s timing in the process of forming the pair bond. But as the siamang duet is thought to have multiple functions, the temporal variation could also be transmitting other information such as individual and group identity while functioning in territorial defense. In addition, anthropogenic noise caused the animals to change their travel behavior and this suggests it could be harmful if faced on a regular basis. Anthropogenic noise can be detrimental if it occurs in home ranges of species that are territorial and facing shrinking habitats due to continued human encroachment. In order to understand if these findings are biologically meaningful and to have firmer conclusions, future long-term studies will need a larger data set over longer periods of time. It is also important to have a larger data set and compare more siamang groups that live in various noise levels and measure variables such as caloric intake, daily travel, copulations, and number of offspring.

A House for the Governor:Settlement Theory, the South Australian Experiment, and the Search for the First Government House.

Copland, Gordon Arthur, gordon.copland@flinders.edu.au January 2006 (has links)
This thesis considers the human spatial occupational behaviour generically called 'settlement'. Within this process a diagnostic index of settlement is created to assist in analysing, defining, and exploring the parameters of 'Settlement Theory'. There is particular reference to Edward Gibbon Wakefield's Theory of Systematic Colonisation in South Australia, as it is one of the few Settlement Theories actually put into practice. Two case studies are examined to develop a transitional argument that connects theory to material outcome. Firstly, considering the macro implications of theory and material culture by comparing the implementation of Wakefield's theory (The South Australian Experiment) and the site, design, and Government Domain of the Capital (Adelaide). Secondly, by considering the micro effect of the theory on material culture in the form of the Governor's residence between 1836 and 1856, including search for the first Government House (Government Hut), to test the connection at this level.

Performing the Canadian "Mosaic": Juliette Gauthier, Florence Glenn, and the CPR Festivals of Quebec City

Sheedy, Erin January 2014 (has links)
The Quebec City festivals of 1927 and 1928 represent a unique instance of close collaboration between prominent figures in Canadian musical and cultural history, John Murray Gibbon and Marius Barbeau. Based on Anglocentric concerns for a unique Canadian identity and corresponding school of composition, the festivals served as points of contact between many artists and performers, including Juliette Gauthier and Florence Glenn. An analysis of specific performances at the CPR festivals and over the course of Glenn and Gauthier’s respective careers showcase how racialized attitudes towards Indigenous populations, and the static conceptualization of French-Canadian folk culture were navigated to perform “Canadian folksong.”

Philosophic historiography in the eighteenth century in Britain and France

Brereton, Mary Catherine January 2007 (has links)
The subject of this thesis is the by now traditional grouping of certain innovative works of historiography produced in eighteenth-century Britain and France; namely the historical works of Voltaire, and the historical writings of the philosophes; and, in Britain, the histories of Hume, Robertson, and Gibbon. This thesis gives a historical and expository analysis of the individual strategies of literary self-fashioning and generic appropriation which underlie this impression of resemblance. It particularly demonstrates that the major characteristics of the contemporary vision of philosophic historiography – the idea of a European history of manners or l’esprit humain, and the insistence on the rejection of the practices of the érudits – which have become incorporated within scholarly definitions of ‘Enlightenment historiography’, are well-established generic tropes, adapted and affected in France as in Britain, by authors of diverse ambitions. The invitation to assume inauthentic connections contained within the practice of philosophic historiography is shown to be embraced by Gibbon, in a notable literary challenge to the paradigms of intellectual history. This study contrasts the textual evidence of these authors’ experience of literary, personal, and political challenges regarding the definition of their role as public, intellectual writers, to the acquired image of an ideal of ‘Enlightenment writing’. It considers the Frenchness of philosophie, and the potential Britishness of Hume, Robertson, and Gibbon. As part of its wider analysis of the practice of intellectual writing with a historical focus, its scope includes the writings of British clerics and writers on religion; of French academicians; and of the late philosophe Volney, and Shelley his interpreter. The major conclusion of this thesis is that eighteenth-century British and French history writing does not support any synthesis of an Enlightenment historical philosophy, narrative, or method; while it is suggested that one of the costs of the construct of ‘Enlightenment’, has been the illusion of familiarity with eighteenth-century intellectual culture, in France as well as Britain.
