As ecologists are being called upon to predict the consequences of human perturbations to natural communities, an important goal is to understand what factors drive variability or consistency in nature. In the rocky intertidal of San Juan Island, Washington, a comparative experimental approach was used to investigate spatial and temporal variation in community organization. The effect of predation on B. glandula varied dramatically over small spatial scales between microhabitats but was remarkably consistent over time withing a given microhabitat. The effects of predation on S. cariosus varied over time within the same microhabitat. By repeating previous landmark experiments at our study site, and replicating these experiments across microhabitats, the domain of applicability of previous experimental information was greatly expanded. In an early successional assemblage on the Oregon coast, I tested the hypothesis that, when the direct effect of one species on another increases in relative strength, its total effect (direct + indirect) is less variable or conditional than if the link between those species is weak. The effect of strong predation by whelks was less sensitive to the presence of additional species and more consistently dampened natural variation between experimental starting dates and between individual replicates within a given experiment. In contrast, the outcome of weak predation was more spatially and temporally variable in sign, and whether it magnified or dampened differences between individual replicates varied between experiments. Consequently the mean total effect of weak predation generally did not differ significantly from zero. However, in some cases, the range of variation (both within and between experiments) in the effect of weak predation exceeded the magnitude of the strongest total effect observed. Longer term results of the experiments on the Oregon coast examined the role of historic factors in influencing the degree to which successional paths are canalized and repeatable or contingent and variable. Succession in mid-intertidal patches in the mussel bed displayed complex patterns of historic effects that varied between species and between different stages of succession. Despite its potential complexity, this system exhibited some consistent and repeatable patterns of succession. Some important canalizing, or noise-dampening forces in this system included: 1) physiological and life-history constraints, 2) compensatory responses of functionally redundant species, and 3) strong interactions between species. / Graduation date: 1996

The figure of Don Juan with its numerous variations and adaptations has been widely discussed in secondary literature. However, one of the most recent adaptations of the character, Peter Handke’s novel Don Juan (erzählt von ihm selbst) (2004) has up to now been neglected. This study tries to provide the first in-depth analysis of Handke’s book while specifically centering on the character of Don Juan himself. The examination strives to determine whether Don Juan, as portrayed by Handke, can still be understood as a real embodiment with roots in the literary tradition or whether the author simply evokes an identical name without establishing any real accordance. In order to evaluate this specific treatment of Don Juan, it is necessary to establish a theoretical framework which provides some insight into the recurrent features that constitute the theme itself. This context will be instituted by the means of identifying motifs and structures essential for understanding Don Juan’s place in world literature while relying on the definitions of the terms “Motiv” and “Stoff” as they were formulated by Elisabeth Frenzel. The analysis of Handke’s Don Juan (erzählt von ihm selbst) is structured into three parts. Handke’s treatment of traditional motifs forms the first part of this interpretation whereas an identification of thematic innovations serves as a second part. The analysis concludes with a contextualisation of typical Handke thematic preoccupations. These are inextricably incorporated into his treatment of the Don Juan motif and therefore absolutely necessary to provide a comprehensive evaluation of this work. The thesis affirms that Peter Handke’s Don Juan can be regarded as a convincing new interpretation of the traditional Don Juan character. The author manages to include all the relevant recurrent features that constitute the Don Juan theme but enhances them with iv innovations which reveal new aspects of the character. Some suggestions for further research, e. g. an in-depth intertextual analysis or a psychoanalytical approach conclude the thesis.

A 5km swath-width SeaMARC I sidescan sonar survey, conducted over the zone of overlap between the southern rift zone of Axial Volcano and the northern tip of the Vance spreading segment on the Juan de Fuca Ridge (between 45°24'N and 45°50'N latitude), was analyzed to locate the present position of the Juan de Fuca spreading axis, and to determine the tectonic and volcanic structure of the seafloor. Sidescan data were processed in concert with the ship's Loran-C navigation to construct navigated, orthorectified mosaics of the sidescan imagery. In order to navigate the sidescan swaths, a simple numerical model was developed to describe the tracking behavior of the towed sidescan vehicle. Successive positions and orientations of the sidescan towfish were estimated, and were used to assign latitude/longitude values to individual sidescan pixels. Navigated sidescan pixels were mapped by computer onto an absolute (latitude/longitude) reference grid, and the resulting sidescan mosaic was compared directly to existing high-resolution SeaBeam bathymetry in order to discriminate the effects of large- and small-scale roughness on the observed backscatter distribution. The Juan de Fuca spreading axis between 45°25'N and 45°39'N is located within the axial valley of the Vance segment. Relative age relationships, based on crosscutting and superposition principles, indicate that the most recent volcanism within the axial valley has occurred along the valley's central ridge, and that the most recent resolvable extension within the axial valley has been concentrated between the central ridge and west valley wall. The Vance segment terminates at 45°39'N, and is not associated with a transform fault. The south rift zone of Axial volcano is a constructional volcanic feature that is not faulted, and a discrete axis of spreading over the south flank of Axial volcano is not resolvable in the sidescan imagery; however, the spreading locus north of 45°39'N is constrained to a zone between 130°06'W and 129°54'W. The lack of a well-defined spreading axis north of 45°39'N indicates that the physical manifestation of the divergent plate boundary has been modified or masked by hotspot volcanic processes associated with Axial volcano such that a definitive locus of spreading is not expressed in the surface morphology. / Graduation date: 1989
