Impacts of space, abundance and food web structure on parasite life cycles
The search for fundamental patterns or rules by which parasites establish and persist in free-living species is a rapidly expanding area of interest for both parasitologists and ecologists. Though host-parasite interactions are fairly well understood at the population level, little is known about parasitism at the community level, nor why some free-living species harbor many parasite taxa while others are seemingly resistant to parasite establishment. The purpose of this dissertation was to explore several species and community attributes that could be important to parasite establishment and persistence in both a marine saltmarsh (Tuckerton, NJ) and a freshwater riverine system (Raritan River, NJ). This study specifically emphasized feeding interactions, abundance and spatial distributions of free-living species and their respective helminth parasites. In Tuckerton saltmarsh, I observed a strong spatial patterning in trematode infections of the mudsnail, Ilyanassa obsoleta, and this pattern is strongly correlated with habitat type and host quality. At the community level (along with data from four previously published systems), trophically transmitted parasites were found to utilize asymmetric predator-prey interactions, in which predator hosts have many prey items and prey hosts have relatively few predators. In a pristine site along the Raritan River high resolution abundance data revealed that predator-prey interactions are spatially constrained by habitat and that this pattern was even stronger for host-host and parasite-host interactions. Finally, I found a decrease in efficiency of biomass transfer up trophic levels across a perturbation gradient in this river system. This pattern correlated with losses in both free-living and parasite diversity. However, the relationship between these factors and human impact was not linear, suggesting a threshold at which community structure becomes less invasible by parasites. Collectively, this study suggests that spatial context, in combination with community structure, can greatly affect parasite establishment and persistence and can be used to explain or predict which free-living species are more hospitable hosts.Ph.

An examination of selected works for percussion; Concerto for marimba and wind ensemble by David Gillingham, XL plus one by Alvin Etler, March from eight pieces for four timpani by Elliott Carter, 42nd street rondo by Wayne Siegel, Oceanus by Steve Houghton and Wendell Yuponce
Master of MusicDepartment of MusicKurt R. GartnerThis is a report intended for musicians planning to perform any number of, or scholars seeking to enrich understanding of, the following compositions: Concerto for Marimba and Wind Ensemble by David Gillingham, XL Plus One by Alvin Etler, March from Eight Pieces for Four Timpani by Elliott Carter, 42nd Street Rondo by Wayne Siegel, and Oceanus by Steve Houghton and Wendell Yuponce.
Each work is analyzed in accordance with Jan Larue's method of style analysis. For some compositions, analysis of harmony has been omitted. For all compositions, the author has added a pedagogical realm of analysis, dedicated to notable performance considerations, interpretive possibilities, and technical considerations, to Larue's organizational scheme. Therefore, the approach taken in this document can be expressed as: Sound, Harmony, Melody, Rhythm, Growth, and Performance
Applications of artificial neural networks in the identification of flow units, Happy Spraberry Field, Garza County, Texas
The use of neural networks in the field of development geology is in its infancy. In this study, a neural network will be used to identify flow units in Happy Spraberry Field, Garza County, Texas. A flow unit is the mappable portion of the total reservoir within which geological and petrophysical properties that affect the flow of fluids are consistent and predictably different from the properties of other reservoir rock volumes (Ebanks, 1987). Ahr and Hammel (1999) further state a highly "ranked" flow unit (i.e. a good flow unit) would have the highest combined values of porosity and permeability with the least resistance to fluid flow. A flow unit may also include nonreservoir features such as shales and cemented layers where combined porosity-permeability values are lower and resistance to fluid flow much higher (i.e. a poor flow unit) (Ebanks, 1987).
Production from Happy Spraberry Field primarily comes from a 100 foot interval of grainstones and packstones, Leonardian in age, at an average depth of 4,900 feet. Happy Spraberry Field is unlike most fields in that the majority of the wells have been cored in the zone of interest. This fact more easily lends the Happy Spraberry Field to a study involving neural networks.
A neural network model was developed using a data set of 409 points where X and Y location, depth, gamma ray, deep resistivity, density porosity, neutron porosity, lab porosity, lab permeability and electrofacies were known throughout Happy Spraberry Field. The model contained a training data set of 205 cases, a verification data set of 102 cases and a testing data set of 102 cases. Ultimately two neural network models were created to identify electrofacies and reservoir quality (i.e. flow units). The neural networks were able to outperform linear methods and have a correct classification rate of 0.87 for electrofacies identification and 0.75 for reservoir quality identification

Session A6: Timing, Frequency and Environmental Conditions Associated with Mainstem-Tributary Movement by a Lowland River Fish, Golden Perch
Presenting Author Bio: Wayne Koster is a scientist (fish ecology) at the Arthur Rylah Institute for Environmental Research with over 10 years’ experience in fisheries research and management. The focus of much of Wayne’s recent work directly relates to the movement and migration of threatened native fish, and responses to conservation initiatives such as environmental flows. Wayne has an extensive knowledge of the ecology and habitat requirements of Australian freshwater fish and is currently leading projects to evaluate the effects of environmental flows on native fish movement and reproduction in various inland andAbstract: Tributary and mainstem connections represent important corridors for the movement of fish and other biota throughout river networks. We investigated the timing, frequency and environmental conditions associated with movements by adult golden perch (Macquaria ambigua) between the mainstem of the mid-Murray River and a tributary, the Goulburn River, in southeastern Australia, using acoustic telemetry over four years. Golden perch moved freely between mainstem and tributary habitats. The results of the study indicate that a spatially and temporally complex relationship between adult golden perch movement, river discharge and water temperature plays a key role in connecting mainstem and tributary populations of the species. The relatively common occurrence of movement across the mainstem–tributary junction suggests that this geographic feature does not function as an impermeable behavioural or demographic boundary between populations in the two rivers. This finding highlights the fact that fish populations do not necessarily conform to artificially constrained management units, and demonstrates the need to consider the spatial, behavioural and demographic interdependencies of aquatic fauna across riverscapes. Although they are often complex, the behavioural mechanisms and associated environmental conditions that influence connectivity across mainstem– tributary interfaces need to be understood and accounted for during development of models that underpin management actions for riverine fishes
