Abstract (sommario):

The object of this thesis is to provide, through a thorough analysis of human perception and interaction with aesthetics and landscape quality, a comprehensive basis on which to develop a credible methodology for the large scale assessment of perceived landscape quality. The analysis of human perception and interaction with aesthetics and landscape quality is gained by inquiring in depth into a range of theoretical constructs from key disciplines, cultural aspects, and empirical studies covering : 1. the contribution of philosophers to aesthetics 2. the psychology of perception and colour 3. the contribution of Gestalt psychology to aesthetics 4. the psychoanalytical construct of human responses to aesthetics 5. the influence of culture on landscape preferences, tracing the changing perceptions of mountains, the portrayal of landscapes in art, and the design of parks and gardens 6. a review of over 200 surveys of landscape quality in the late 20th century, including typologies and theories of landscape quality Based on the analysis of these and the knowledge gained, an empirical study is formulated and conducted, comprising a study of landscape quality of South Australia, an area of nearly 1 million km - 1. This involves, firstly, the acquisition of data covering the delineation of landscape character regions for the State, photography of these landscapes, derivation of a set of representative slides, and rating of these by groups of participants. Secondly, these preference ratings are comprehensively analysed on the basis of the attributes of the scenes covering land form, land cover, land use, water bodies, naturalism, diversity and colour. Thirdly, the results are applied as follows: 1. a map of landscape quality of South Australia is derived 2. the results are used to predict the effect that changes in land use ( e.g. clearance of trees ) will have on landscape quality 3. the theoretical constructs of landscape quality are evaluated on the basis of the preference ratings 4. a protocol is detailed to guide the undertaking of large - scale landscape quality assessment. The thesis thus fulfils the objective of conducting a thorough analysis of human perception and interaction with, aesthetics and landscape quality, to provide a basis for developing a credible methodology for the large - scale assessment of perceived landscape quality.

Abstract (sommario):

Together with their wives Otto and Richard Schomburgk arrived in Port Adelaide (South Australia) on August 16th 1849. The essay looks at how these two brothers, who had received their scientific training and promotion in the circle surrounding Alexander von Humboldt, reacted to the unfamiliar conditions in the young British colony. Some indication will be given as to the differences between the Schomburgk brothers treatment of the natural resources of the new colony and that of the English colonists of the time.
Otto und Richard Schomburgk erreichten zusammen mit ihren Frauen Port Adelaide (Südaustralien) am 6. August 1849. Der Beitrag geht der Frage nach, wie die Brüder, die ihre wissenschaftliche Ausbildung und Förderung im Umkreis von Alexander von Humboldt erhalten haben, auf die unbekannten klimatischen Bedingungen in der noch jungen englischen Kolonie reagierten. Dabei soll die Differenz der Schomburgk Brüder zu den englischen Kolonisten im Umgang mit den Ressourcen der neuen Kolonie sichtbar werden.

Abstract (sommario):

Palaeobotany illuminates past environments by relating the fossilised species to the existing geological conditions. This has previously been done with fossilised leaves and spores but not with fossilised wood. The recovery of a significant quantity of wood from an area of Tertiary sediments in New South Wales, enabled the used of fossilised wood as a palaeoenvironmental tool. Tertiary sedimentary deposits of south eastern Australia are diverse lithologically, occupy distinct areas and are limited in vertical and horizontal extent. However, samples in museum collections together with samples from field work and descriptions of fossil wood from previous researchers enabled an analysis of the fossil wood. The geological and palaeontological aspects of the fossil wood were considered for each specimen. Only specimens with precise information concerning location and description of the sedimentary deposits in which the specimens were found were investigated. Lithology, sedimentary structures and the relationship with surrounding geological units were also considered. The samples were then classified and identified. It was possible to identify fossil wood to Family level by comparison with existing taxa. In the majority of cases, identification to species level was not possible due to the lack of detail in the specimen and because features such as colour cannot be used with fossilised specimens. With Australian fossilised wood, a systematic nomenclature based on structure observed within the palaeotaxa, would be more relevant. Comparisons of cell structures with previous work on palaeoenvironmental indicators was found to be possible. Fossil wood has two uses. Firstly, as a local environmental indicator, usually in conjunction with sedimentological data, assessing the rate and direction of water flow, types of depositional environments and localised floral assemblages. Secondly, as an indicator of regional climate. Within any one particular time period, comparisons between the cellular structures of wood found in different parts of south eastern Australia show gross changes in cell size, mean growth ring size and vessel size, which enabled generalisations about climate for each epoch in the Tertiary. Palaeoclimatic indicators from the wood concurred with previous climatic interpretations based on palynology and sedimentology. Cool conditions during the Palaeocene were clearly indicated by small cells and small growth rings which gradually increased throughout the remainder of the Tertiary. Several areas e.g., Dargo High Plains, where cold conditions existed in isolation could be clearly distinguished. This corresponds with the gradual northward movement of the Australian plate with consequent increasing temperatures on the mainland.

Abstract (sommario):

This study examines the variability of the stone assemblages at the mound springs campsites in South Australia. The research area is part of the tribal territories of Arabana and Diyari people. It comprises a network of mound springs stretching for about 200 km along the south and southwest shores of Lake Eyre. These mound springs were vital for permanent occupation of this arid region in late prehistory and in the post contact period. Large campsites located near the major springs attest to the prehistoric occupation of the area. Historical accounts reveal that this occupation was abruptly terminated in early 1 8 6 0’s. Although environment and chronology are uniform for all the mound spring sites the assemblages are distinctly different. They vary in the proportions of lithic materials, tool types, and artefact size. Inter-site variability is prominent while intrasite variation is minimal. The research is focused on this fact as it provides an important clue to the nature of springs o c c u p a t i o n. It is demonstrated that the variability of the mound spring campsites reflects different tactics of use and economy of lithic materials at each site. These tactics were influenced by: a) availability of different lithic materials and b) different demands for processing organic materials. It is argued that assemblage patterning is sensitive to local circumstances, and affected by quantity and quality of resources at each site. Consequently the variability between assemblages reflects the overall organisation and strategy of land use. This study attempts not merely to reconstruct human behaviour at each site but rather to understand how this behaviour was organised on the strategic level. This level of organisation is best represented by the differential use of sites within a common settlement system. Organisation such as this suggests consistent links between groups of people in the mound springs area throughout the last thousand years.

Bibliography: leaves 185-200. The herbicides norflurazon, oxadiazon, oxyfluoren, trifluralin and simazine used in South Australian viticulture were assessed for mobility and degradation through a combination of laboratory and field experiments. Sorption, leaching and dissipation rates were measured, as was presence in shallow groundwater. The fate of herbicides from vine to wine was also investigated, tests being conducted on herbicide residue in both white and red grapes and presence in wine. A proposal for good environmental management of herbicide use in vineyards to minimise the effects of herbicides was also developed.

Abstract (sommario):

Diseases in natural ecosystems are often assumed to be less severe than those observed in domestic cropping systems due to the extensive biodiversity exhibited in wild vegetation communities. In Australia, it is this natural biodiversity that is now under threat from Phytophthora cinnamomi. The soilborne Oomycete causes severe decline of native vegetation communities in south-western Victoria, Australia, disrupting the ecological balance of native forest and heathland communities. While the effect of disease caused by P. cinnamomi on native vegetation communities in Victoria has been extensively investigated, little work has focused on the Anglesea healthlands in south-western Victoria. Nothing is known about the population structure of P. cinnamomi at Anglesea. This project was divided into two main components to investigate fundamental issues affecting the management of P. cinnamomi in the Anglesea heathlands. The first component examined the phenotypic characteristics of P. cinnamomi isolates sampled from the population at Anglesea, and compared these with isolates from other regions in Victoria, and also from Western Australia. The second component of the project investigated the effect of the fungicide phosphonate on the host response following infection by P. cinnamomi. Following soil sampling in the Anglesea heathlands, a collection of P, cinnamomi isolates was established. Morphological and physiological traits of each isolate were examined. All isolates were found to be of the A2 mating type. Variation was demonstrated among isolates in the following characteristics: radial growth rate on various nutrient media, sporangial production, and sporangial dimensions. Oogonial dimensions did not differ significantly between isolates. Morphological and physiological variation was rarely dependant on isolate origin. To examine the genetic diversity among isolates and to determine whether phenotypic variation observed was genetically based, Random Amplified Polymorphic DNA (RAPD) analyses were conducted. No significant variation was observed among isolates based on an analysis of molecular variance (AMQVA). The results are discussed in relation to population biology, and the effect of genetic variation on population structure and population dynamics. X australis, an arborescent monocotyledon indigenous to Australia, is highly susceptible to infection by P. cinnamomi. It forms an important component of the heathland vegetation community, providing habitat for native flora and fauna, A cell suspension culture system was developed to investigate the effect of the fungicide phosphonate on the host-pathogen interaction between X. australis and P. cinnamomi. This allowed the interaction between the host and the pathogen to be examined at a cellular level. Subsequently, histological studies using X. australis seedlings were undertaken to support the cellular study. Observations in the cell culture system correlated well with those in the plant. The anatomical structure of X australis roots was examined to assist in the interpretation of results of histopathological studies. The infection of single cells and roots of X. australis, and the effect of phosphonate on the interaction are described. Phosphonate application prior to inoculation with P. cinnamomi reduced the infection of cells in culture and of cells in planta. In particular, phosphonate was found to stimulate the production of phenolic material in roots of X australis seedlings and in cells in suspension cultures. In phosphonate-treated roots of X australis seedlings, the deposition of electron dense material, possibly lignin or cellulose, was observed following infection with P. cinnamomi. It is proposed that this is a significant consequence of the stimulation of plant defence pathways by the fungicide. Results of the study are discussed in terms of the implications of the findings on management of the Anglesea heathlands in Victoria, taking into account variation in pathogen morphology, pathogenicity and genotype. The mode of action of phosphonate in the plant is discussed in relation to plant physiology and biochemistry.

Abstract (sommario):

Salsola australis is an introduced weed of crop and pasture systems in the Western Australian broad acre cropping and pasture region (wheat-belt). This thesis investigated the classification, biology and ecology of the genus Salsola in southwest Australia, as well as modelling the effectiveness of possible weed control practices. Prior to this research, S. tragus was the only recognised species of the Salsola genus within Australia. However, genetic analysis revealed that four genetically distinct putative taxa of the genus Salsola were found in southwest Australia, none of which were S. tragus. The taxa that is the most prevalent agricultural weed was classified as S. australis, but the other three putative taxa could not be matched to recognised species. All four taxa were diploid (2n = 18), as opposed to tetraploid (2n = 36) S. tragus. Within the agricultural system of southwest Australia, S. australis plants established throughout the year, although the majority of seed production occurred in late summer and autumn. Total seed production (138-7734 seeds per plant) and seed viability (7.6-62.8%) of S. australis were lower than that reported for other agricultural weed species of the Salsola genus. Seed dispersal occurred when the senesced plants broke free of their root system to become mobile. Wind driven plants travelled and shed seed over distances of 1.6 to 1247.2 m. Movement of approximately half the plants was restricted to less than 100 m by entanglement with other S. australis plants within the stand. Some seed was retained on the senesced plants, but the germinability of this seed fell to less than 2% in the two month period following plant senescence (i.e. a decline of 79%). Once seed shed into the soil seed bank, anywhere from 32.3 to 80.7% of the viable seeds germinated in the year following seed production, with the rest remaining dormant or degrading. A model of the life cycle of S. australis based on the population ecology data indicated that the dormant seed bank had very little effect on annual seedling recruitment, but seed dispersal from neighbouring populations had a large impact on population growth rate. Therefore, the most successful weed control measures were those that restricted seed dispersal from neighbouring populations, or those that were applied to all populations in the region rather than to a single population. Weed control techniques applied to a single population, without reducing seed dispersal, could not reduce population size.

Abstract (sommario):

Douglass North's institutional framework is employed in this thesis to explain the disparate rates of economic growth between colonial Western Australia and South Australia. The differences in colonisation affected the design of institutions subsequently transferred to these colonies which had more of an impact of development than previously thought. By 1900, both colonies had roughly equal growth rates but this convergence only eventuated after Western Australia eliminated the worst deficiencies resulting from its foundation and reformed its institutional matrix.

Abstract (sommario):

Many researchers have recognized the value of investigating the history of race contact in Australia, but too few have sought to explain in detail why the Aboriginal population declined so much and so rapidly when colonization advanced across the continent. The central aim of this thesis is to identify and assess the impact of the major causes of Aboriginal population collapse in the Riverland (Murray River) region of South Australia. It is estimated that prior to 1800 the population density of the Riverland was between 0.3 and 0.5 km^ per person with a total population for the region of around 3000. In 1881 the South Australian State Census enumerated just 14 Aboriginal people for the Riverland region. The population collapse has been viewed in two stages. The first has been termed pathological contact and is considered to be the major cause of the collapse. Introduced venereal syphilis, gonorrhoea and smallpox spread ahead of the major European frontiers of South Australia causing extreme mortality among the Riverland Aborigines. The second stage began after European settlement of South Australia. Violent clashes were quick to erupt on the overland cattle route which linked the settlement of Adelaide with the Eastern settlements. The combined effect resulted in an increase in the mortality rate, a decrease in the fertility rate and social and economic disruption. The population was unable to recover.
