Aromatic hydrocarbon contaminants : investigations of detection methods, bioremediation strategies, and toxicity impacts

Creator:: Huizenga, Juliana M.
Abstract:: Aromatic hydrocarbons represent a large class of environmental contaminants that have a broad range of structures, physicochemical properties, and toxicities. Arising from the burning of organic matter, particularly fossil fuels, they are both widespread and abundant in all environmental compartments. Both monoaromatic hydrocarbons (BTEX) and polycyclic aromatic hydrocarbons (PAHs) are...

Utilizing a Lab-Based Minority Stress Paradigm for Experimental Research among Sexual and Gender Minority Groups: Application and Considerations

Creator:: Fahey, Kalina M. L.
Abstract:: Sexual and gender minority (SGM) samples report elevated rates of substance use and substance use disorder compared to their heterosexual and cisgender counterparts across a wide variety of substances (Connolly & Gilchrist, 2020; Krueger et al., 2020; Rice et al., 2019), in part due to the experience of minority stress....

Estimation and Sparse Selection of Conditional Probability Models for Vector Time Series

Creator:: Ruiz, Trevor D.
Abstract:: Diverse scientific fields collect multiple time series data to investigate the dynamical behavior of complex systems: atmospheric and climate science, geophysics, neuroscience, epidemiology, ecology, and environmental science. Identifying patterns of mutual dependence among such data generates valuable knowledge that can be applied either for inferential or forecasting purposes. Vector autoregressive...

Radon-222 as an in situ partitioning tracer for quantifying nonaqueous phase liquid (NAPL) saturations in the subsurface

Creator:: Davis, Brian M.
Abstract:: This study investigated the use of radon-222 as an in situ partitioning tracer for quantifying nonaqueous phase liquid (NAPL) saturations in the subsurface. Laboratory physical aquifer models (PAMs), field experiments, and numerical simulations were used to investigate radon partitioning in static (no-flow) experiments and in single-well, 'push-pull' tests conducted in...

Effects of pasture and management variables on forage intake by grazing sheep

Creator:: Lewis, Robert David
Abstract:: Grazing experiments were conducted in summer, autumn and winter to assess the effects of stock density, grazing duration, pre-grazing pasture mass and stock type on forage intake by sheep grazing at high stock densities for short durations. In summer and winter, sheep were stocked at 200 sheep/ha on 0.1 ha...

Eelgrass-macroalgae interactions; context-dependency in upwelling-influenced estuaries

Creator:: Hessing-Lewis, Margot
Abstract:: This dissertation investigates the context-dependency of species interactions between seagrass and macroalgae in upwelling-influenced estuaries. In all coastal systems, nutrient loading is multidirectional, resulting from mostly freshwater and marine inputs. The directionality of nutrient inputs may affect the rate of supply of organic matter to the system. In systems where...

Alternative orchard floor management practices, soil quality, nitrogen fertilizeruptake, and apple tree growth and yield

Creator:: McDonald, Sarah Finger
Abstract:: Orchard floor management (OFM) practices can improve soil function and alter the soil biological community. Soil function is dependent on soil forming materials and on management practices but little is known about how OFM affect orchard soil quality, fertilizer N uptake, or tree growth and production. Research plots were located...

The roles of nutrient dynamics, oceanography, and light in the structure and functioning of rocky intertidal macrophyte assemblages

Creator:: Close, Sarah L.
Abstract:: The influence of the physical environment on organisms has long been a subject of ecological research. But, the complex drivers of environmental variation, and the multiple scales at which this can occur, make studying this topic a difficult challenge. In rocky intertidal habitats, oceanographic- and climate-scale variability influence benthic communities...

Assessment of a model to predict attitudes and behavior of vocational teacher trainees toward handicapped individuals

Creator:: Stephens, Sarah
Abstract:: A major problem of this study was to assess a model for predicting attitudes and behavior of vocational teacher trainees toward handicapped learners. A second problem was to determine whether or not both attitudes and behavior of vocational teacher trainees toward handicapped learners could be changed. The sample for this...

The effects of land use on mineral flat wetland hydrologic processes in lowland agricultural catchments

Creator:: Marshall, Sarah M.
Abstract:: Hydrologic processes within mineral flat wetlands, along with their connections to groundwater and downstream surface water in lowland agricultural catchments are poorly understood, particularly under different land uses. In the three field studies included in this thesis, we examined infiltration, wetland hydroperiod, groundwater recharge dynamics, surface runoff generation, and water...
