Giant City State Park in Makanda, Illinois contains graffiti created by passersby and local residents. Many deem modern graffiti in parks as a depreciative behavior. However, the inscription created by Theodore Wilson Thompson in 1862 along the Giant City Nature Trail has implications for interpretive use by park staff. This is due to the inscription being etched prior to the park's establishment and Theodore's pioneering contributions to Makanda and Carbondale, Illinois. Therefore, Theodore Thompson was the focus of this study due to his inscription and the lack of park research conducted on his life history. In 1852, as a young boy, he moved to the Makanda vicinity with his family. Theodore and his brother Albert carved their names in sandstone during the Civil War, in an area that would later become part of Giant City State Park. After owning a large fruit farm as an adult and increasing the size of the town of Makanda, Theodore moved to Carbondale where he purchased 600 acres adjoining what would become Southern Illinois University. Thompson Woods and Thompson Lake (Campus Lake) were established by Theodore and were later added to the campus of Southern Illinois University. Through the documentation and research of other names etched throughout the park, it will be possible for park staff to not only create interpretive media to help visitors better connect with the resource, but also help preserve the history of the area before it became a park.

In contrast to the relatively rapid changes occurring in the modern American army, the period between the end of the War of 1812 and the beginning of the Mexican War offers a definite period for a study of military life when reform came slowly.

A growing understanding of complex biotic interactions clarified the importance of symbioses with respect to the ecology and evolution of life. In particular, knowledge of symbioses between eukaryotes and microorganisms such as bacteria and fungi has revolutionized the fields of medicine and agriculture, and made clear the roles of microbes in fostering human and environmental sustainability. For example, diverse fungi associate with the seeds of plants following dispersal. These fungi can influence seed survival and germination in a host-specific and spatially explicit manner, thus influencing plant community dynamics in agricultural and natural systems. In species-rich tropical forests, seed-fungus interactions are emerging as one of the most important aspects of plant demography and community ecology. However, even closely related fungi can have opposing effects on seeds of particular plants, such that mechanisms influencing host-specific effects require further attention. Such mechanisms can include genomic traits of fungi and hosts, and the environmental context of interactions. However, studies have shown that many fungi also harbor endosymbionts than can influence their functional traits. In particular, fungi often harbor endohyphal bacteria that influence fungal phenotypes. This suggested the potential for similar, co-occurring microbes to influence the ecology of seed-associated fungi. Here, I explore the diversity, evolutionary relationships, and influence on fungal phenotypes of endohyphal bacteria inhabiting seed- and leaf-associated fungi with a focus that begins in tropical forest ecology and expands to include gene expression in an emerging model system from the temperate zone. To determine the occurrence, abundance, taxonomic diversity, and phylogenetic diversity of endohyphal bacteria among tropical seed-associated fungi, my coauthors and I used PCR and fluorescence microscopy to screen members of two common orders of seed-associated fungi, comparing their communities to those in closely related foliar endophytic fungi. We revealed a high frequency and diversity of endohyphal bacteria among both groups of fungi. We then used phylogenetic and community ecological analyses to show a lack of congruence between phylogenies of bacteria and fungi. Although seed-associated and foliar endophytic fungi share evolutionary histories, they harbor distinct endohyphal bacterial communities. To explore the influence of endohyphal bacteria on fungal phenotypes important for interactions with seeds, my coauthors and I examined a single fungus-bacterium pair consisting of a member of a well-known group of pathogenic fungi found to harbor an endohyphal bacterium closely related to those with known chitinolytic activity. We created fungal clones that were free of endohyphal bacteria, and carried out a phenotypic microarray assay comparing use of 95 unique carbon sources by cured and uncured clones. Across the majority of substrates, the fungal clones harboring endohyphal bacteria grew more rapidly and to a greater extent than the cured clones. Thus the endohyphal bacterium was associated with broader substrate use and more effective use of a variety of substrates relevant to plant biology, including seed germination. To assess the influence of endohyphal bacteria with respect to the outcomes of seed-fungus interactions, my coauthors and I examined six fungus-bacterium pairs and their interactions with the seeds of five tropical pioneer tree species. We showed that although endohyphal bacteria have little impact on colonization of seeds by fungi, they significantly altered the survival and germination of infected seeds. In most cases, endohyphal bacteria reduced the negative impacts of fungi on seeds: strains harboring them responded more similarly to uninoculated controls, whereas strains cured of them exhibited significantly reduced survival and germination. Seeds infected by fungi of the same genotype that differ with respect to the identity of their endohyphal bacteria exhibited differences, but so did seeds infected by strains of those isolates not harboring bacteria, suggesting that factors in addition to the presence of endohyphal bacteria can drive variation in the outcomes of seed-fungus interactions. Together these analyses suggest intricate interactions between fungi and bacteria that result in context-dependent outcomes. This turned our focus to gene expression as a means to understand mechanisms of interactions between endohyphal bacteria and their fungal hosts. Last, my coauthors and I describe methods we developed to co-culture fungi and their endohyphal bacteria for downstream analysis of differences in gene expression among a fungus-bacterium pair and axenic cultures of each symbiont. We focused on an emerging model system: a foliar endophytic strain of Pestalotiopsis aff. neglecta (Ascomycota) known to harbor an endohyphal bacterium in the genus Luteibacter (Xanthomonadaceae). The focal bacterium is in part reliant on its host fungus for acquisition of certain sulfur-containing compounds such as sulfate. We showed that inoculating a low-methionine growth medium with bacteria recovered in exponential phase from a high-methionine medium supports growth suitable for comparing axenic growth with that in co-culture with its host fungus. Although bacterial cell density in co-cultures was significantly greater than that in axenic cultures, the opposite was true for the host fungus. We expect results from transcriptomics analyses to reflect partial reliance on– and antagonism of Pestalotiopsis by Luteibacter, and here present the first pipeline of methods for examining gene expression for a facultatively symbiotic endohyphal bacterium and its host, a member of the most species-rich and economically important fungal phylum.

This study is an examination of frontier movement and economic development in a portion of the Canadian Shield--Northeastern Ontario--in the period from 1850 to 1914. The process of frontier advance is examined with reference to five key elements: (1) the nature and distribution of resources; (2) external economic and cultural forces; (3) technological change, with emphasis on transportation developments; (4) public policy; and (5) entrepreneurship. The interrelationships of these factors are analysed to explain the spatial distribution of settlement and frontier-core interaction in the Nipissing Lowlands, the Algoma-Sudbury district, and the Timiskaming area. Significant changes occurred in both the process and pattern of frontier advance. The direction of movement in the nineteenth century was foreshadowed by the earlier fur trade, which was followed in some areas by logging and subsidiary agriculture. Inward movements of people and frontier-core interaction were oriented toward Montreal via the Ottawa Valley transportation linkages. In the twentieth century, northward extension of the railway system from southern Ontario gave rise to a dynamic mining frontier. A strong north-south interaction emerged, contrasting with the earlier east-west pattern. Northeastern Ontario, at first almost wholly within the sphere of influence of Montreal, had become part of the economic and cultural hinterland of Toronto by 1914. By 1914 there was established a pattern of land occupance which is still strongly in evidence at present. It was characterized by a high degree of nucleation and a linear orientation of settlement along transportation corridors. The distribution of population and the location of economic activity were usually influenced by the distribution of resources, ease of access, and the presence or absence of government stimulus, entrepreneurial skill, and capital. Economic development was (and still is) based predominantly on the extraction and processing of natural resources for consumption outside the region. Frontier-core interaction was characterized by outbound movements of commodities such as furs, minerals, and wood, either unprocessed or in various stages of manufacture. The introduction of resource-processing industries depended on whether there was less cost to the external consuming area, and to some extent on public policy. / Arts, Faculty of / Geography, Department of / Graduate

Magister Educationis - MEd / Pupils experience various problems when trying to solve problems in Biology, particularly on Higher Grade. This problem was profound in the area of Homeostasis, an aspect of Human Physiology. During this investigation a number of pupils, the PIONEER GROUP, were screened for cognitive deficiencies. Major common deficiencies were identified as IMPULSIVITY, THE USE TWO OR MORE SOURCES OF INFORMATION SIMULTANEOUSLY, SPATIAL AND TEMPORAL ORIENTATION. A second phase, the essence of this investigation, sought ways in which to teach pupils the cognitive skills to facilitate their concept formation in the area of Homeostasis. Since the subjects displaying these cognitive deficiencies were already in their final year of High School a method was sought which would benefit them in the short term. Simultaneously a way had to be found to teach these skills so that it could be of use to pupils on a long term basis. This study revealed that for short term benefit the cognitive skills have to be subtly introduced and integrated with the subject content. Teaching cognitive skills in concentrated form over such a short period had a detrimental effect on the group subjected to this treatment. However, the PIONEER GROUP, had been taught these skills in a very short period in concentrated form. Feedback from them reveals that they were not able to apply the skills in their Senior Certificate Examination but all of them are now adept at using these skills to their benefit. This leads to the conclusion that if these skills are to be taught separately it should be started as early as possible in the school career. In the last year of High School it is more of a burden to the pupil than a benefit. In such a case it should be done integrated with subject content.

RÉSUMÉ The diploma thesis analyses the process of creation of the Pioneer organization, and the gradual prohibition of the Scout organization Junák by the Communist regime at the turn of the 1940s and 1950s. The thesis aims to describe the view of the Junák organization by the Communist regime, and to compare both youth organizations. The first part focuses on the creation of Junák, its development up to 1945, and discusses the organization, meaning and content of the Scout educational method. The second crucial chapter describes the history of the Scout movement after World War II in the context of the post-war tendency to merge youth organizations and give them a single central leadership. The reasons and circumstances under which the Communist regime decided to suspend the activity of the Scout organization and to give full responsibility for the education of children to the Czechoslovak Youth Federation (ČSM) and its part, the Pioneer organization, are examined. The task of the Pioneer organization in the socialist society is described, so are its organization, meaning, symbols and the educational framework. The concluding chapter presents the early activities of Pioneers in the first socialist years to then discuss the socialist view of ethics and the working methods in youth work put forward by the...
