Developing Rapid Indicators To Detect Micropollutants In Coastal Blackwater Rivers In South Carolina, Lydia Winn
Developing Rapid Indicators To Detect Micropollutants In Coastal Blackwater Rivers In South Carolina, Lydia Winn
All Theses
Micropollutants in water sources are found in higher concentrations in areas with high levels of urban and agricultural land. These pollutants can be introduced into water sources during storms and rain events, through water treatment outputs, and commercial or residential waste. These events increase the levels of both nutrients and micropollutants in these water sources. With increasing levels of micropollutants in rivers, this study’s goal was to develop an alternative detection method or an indicator test for the levels of micropollutants in water. We first proposed the use of amicrobial fuel cell (MFCs) operating as a biosensor could be utilized …
Interactive Effects Of Bark Beetles, Ophiostomatoid Fungi, And Subterranean Termites On Wood Decomposition And The Biogeochemical Cycling Of Pine Forests, Kimberlyn Pace
Theses and Dissertations
A frequent source of pine tree mortality in recent years can be attributed to pine bark beetles and their vectored Ophiostomatoid fungi, an organism that has been observed to attract subterranean termites that preferentially recruit to this downed woody debris. This interaction may significantly modify biogeochemical fluxes in bark beetle mass mortality events, but studies are often limited to singular regions or single pine-dominated ecosystems. Two studies were designed to test the interactive effects of these associations on terrestrial biogeochemical cycles and decomposition processes, the first using replicated field trials in Mississippi, Arizona, and Honduras across two years and the …
Combined Effects Of Biochar And Plant Growth Promoting Bacteria Pseudomonas Putida Tsau1 On Plant Growth, Nutrient Uptake Of Wheat, And Soil Enzyme Activities, Dilfuza Egamberdieva, Burak Alaylar, Jakhongir Alimov, Zafarjon Jabbarov, Sonoko Bellingrath Kimura

Turkish Journal of Agriculture and Forestry
Many studies indicate the favorable effect of biochar on soil quality and plant fitness. A few studies on the biochar interactions with rhizosphere bacteria and their impact on plant development and nutrient acquisition have been reported. In this study, pot experiments in a glasshouse were performed to figure out the interactive effect of plant beneficial bacteria Pseudomonas putida TSAU6 and biochar amendment on the wheat (Triticum aestivum L.) growth, nutrient uptake, and soil biological activity. The results demonstrated that root and shoot dry biomass of wheat grown in soil mixed with biochar and combined with P. putida TSAU1 were …
Near-Surface Soil Nitrogen And Vegetation Response To Invasive Emerald Ash Borer In Forested Black Ash Wetlands Of The Western Upper Peninsula, Michigan, Usa, Daniel A. Beyer
Dissertations, Master's Theses and Master's Reports
Invasive emerald ash borer (EAB) (Agrilus planipennis Fairmaire) poses an imminent threat to the structure and function of North American hardwood forests, particularly black ash (Fraxinus nigra Marshall), and alters the hydrologic and ecological services of their wetlands. Black ash trees regularly grow in seasonally saturated soils and are responsible for hydrologic regulation and nutrient cycling. In this study, a gradient of black ash wetlands impacted by EAB were monitored to assess vegetation changes and near-surface soil nitrogen availability. Vegetation community changes were intertwined with nitrogen cycle disturbances following EAB infestation. As black ash died and fell to …
