Activated Carbon Decreases Invasive Plant Growth By Mediating Plant-Microbe Interactions, Nicole E. Nolan
Activated Carbon Decreases Invasive Plant Growth By Mediating Plant-Microbe Interactions, Nicole E. Nolan
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
To restore lands invaded by dense, non-native vegetation, it may be necessary to develop targeted restoration tools than can remove the mechanism used by these non-native species as a competitive advantage. Activated carbon (AC) is one such tool, with the ability to disrupt the mechanisms of plant to plant communication (allelopathy) and positive plant to microbe communication commonly used by non-native species. Previous studies have shown the success of high concentrations, 1000g/m2, of AC in native plant community restoration on a small scale. Here, our goals are twofold: first, to test AC effectiveness in restoring desirable plant communities …
Aquatic Priming Effects In The York River Estuary And Implications For Dissolved Organic Carbon Mineralization, Thomas M. Dunlap
Aquatic Priming Effects In The York River Estuary And Implications For Dissolved Organic Carbon Mineralization, Thomas M. Dunlap
Theses and Dissertations
The priming effect (PE), characterized as the enhanced microbial processing of bio-recalcitrant organic matter with the addition of labile substrates, has been hypothesized to moderate carbon (C) cycling in aquatic systems. In this study, aquatic PEs were evaluated through bacterial respiration and dissolved organic C consumption in incubations of water collected from three locations along the York River estuary. Incubations from White’s Landing on the Pamunkey River, a tidal freshwater tributary of the York, and from Croaker Landing in the middle of the estuary, displayed positive PEs when amended with labile C. In contrast, amended incubations from Gloucester Point, near …
