The Abundance Of Soil Microbes In Relationship To Proximity To The Urban Area Of Lancer Park In Farmville, Virginia, Christian Michael, Callie Cutrell, Miguel Diaz-Montealegre
Spring Showcase for Research and Creative Inquiry
Soil microbes are microorganisms found in soil that serve various critical roles and functions in the environment, such as decomposition and the cycling of nutrients in ecosystems. Natural and human-caused factors can have positive and/or negative impacts on soil microbes. The objective of this study is to examine the abundance of soil microbes in relationship to proximity to the urban area of Lancer Park in Farmville, Virginia. Soil samples were taken from four locations within Lancer Park: the upper and lower floodplain of Buffalo Creek, the bottom of a large stormwater detention pond, and adjacent to an ephemeral channel connecting …

Allelochemicals are biochemicals produced by one plant that inhibits the success of other plants in its vicinity. These allelochemicals are sometimes produced naturally or as a result of stimulus or stress. Ferulic acid is a widespread allelochemical found in cucumbers (Cucumis sativus). Artificial inhibitory chemicals such as the pesticide zeta cypermethrin may create new interactions with ferulic acid. We found that cucumbers acclimate to ferulic acid over time while the inhibitory effects of pesticide remained relatively constant over 14 days.

Spring Showcase for Research and Creative Inquiry
Macroinvertebrates are important biological monitors that play a valuable role in the metabolism of freshwater food chains. Previous studies have suggested that conditions such as dissolved oxygen, pH, water temperature, precipitation, and air temperature can affect the abundance of macroinvertebrates which can in turn affect the health of freshwater ecosystems. This research aimed to find the relationship between macroinvertebrate biodiversity and various environmental conditions in freshwater ecosystems. Weather data was taken from a weather station at Lancer Park and water data was taken on-site at Wilson stream, both locations in Farmville, Virginia. Sample collection and identification occurred twice a week …
