Microplastic Accumulation In Terrestrial Gastropods And Soils, Gregory B. Bonilla
Microplastic Accumulation In Terrestrial Gastropods And Soils, Gregory B. Bonilla
Masters Theses
Microplastics (MPs) have become an emerging threat to ecosystems across the world. Transport, impacts, and fates are grossly understudied, especially in terrestrial environments. Current research on MP bioaccumulation has focused mainly on aquatic organisms with little study of terrestrial organisms, including snails where data are nearly nonexistent. To address this, we collected and examined land snails and their surrounding soil for MP content in shell and tissue. From September 11, 2020, to October 25, 2021, cover boards were placed (n=30) along relatively undisturbed sites in hardwood, forested areas, and tall grasses in a Wildlife Management Area (WMA) in Oak Ridge …

Doctoral Dissertations
This dissertation examined the carbon sequestration potential of a low C:N soil amendment and its incorporation into the soil over a rolling agricultural field. A segmented planar fit was developed to assess and correct the systematic errors the topography introduces on the carbon dioxide fluxes. The carbon dioxide fluxes were then be partitioned into gross primary productivity and soil respiration to understand the influence of the contrasting management practices, using flux variance partitioning. Concomitant with the partitioning, high resolution temporal and spatial scale remote sensing images were interpolated and standardized to conduct hypothesis testing for treatment effects.
Assessment Of Soil Health Under Native Warm-Season Grasses And Different Grazing Management, Kara Leigh Grosso
Assessment Of Soil Health Under Native Warm-Season Grasses And Different Grazing Management, Kara Leigh Grosso
Masters Theses
This research uses analysis of soil quality indicators (SQIs) to compare vegetation species and grazing management over the 2021 grazing season. The soil health effect of the native warm-season grasses (NWSG) big bluestem (BB) (Andropogon gerardii) mixed with indian grass (IG) (Sorghastrum nutans) (BBIG), and switchgrass (SG) (Panicum virgatum), inter-seeded with a 12 species biodiversity mix was investigated in a 5 pressure grazing system (no graze (NG), no rest (NR), early, middle, and late rest (ER, MR, LR)). Additionally, there is a need for inexpensive tools for land owners to assess soil quality, and a validation study …
