Climate change is the long-term alteration in the Earth’s average weather conditions believed to be driven by greenhouse gases (GHG): carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). These alterations are expected to cause more extreme weather events, gradually warmer global temperatures and greater amounts of precipitation. Roughly 20% of the Earth’s CO2, one-third of CH4 and two-thirds of N2O emissions, originate from soils, and earthworms are known to accelerate GHG. As climate change proceeds, there is expected to be an increase in global temperature of 2-6ºC. Temperature …
The Effects Of Silicon Applications On Wear And Drought Stress Of Cool Season Turfgrass, Mike J. Badzmierowski, W. Michael Sullivan
The Effects Of Silicon Applications On Wear And Drought Stress Of Cool Season Turfgrass, Mike J. Badzmierowski, W. Michael Sullivan
Senior Honors Projects
The ability of turfgrass to maintain quality and functionality during use and drought stress are fundamental to almost all turfgrass environments. A possible mechanism to increase wear and drought tolerance is through the use of supplemental silicon (Si) application. Until recently, Si has received little attention for its role in crop physiology or performance.
While it is recoverable within the plant it is not recognized as an “essential” plant growth component. Si is the second most abundant element in the Earth’s crust; however the majority of soil-Si is bio-geochemically inert. Plants absorb Si exclusively as monosillicic acid, H2SiO …

Macroinvertebrate Assemblages and Dynamic Soil Properties: Influence of Dredging: Abstract
The habitat characterization of subaqueous soils is important for inventorying natural resources and monitoring changes in ecosystem processes. This project aimed to characterize benthic communities within coastal ponds of southern Rhode Island, and develop an understanding of how these communities change due to habitat alterations. I explored the distribution of benthic biology among a range of estuarine subaqueous soils and the effect of anthropogenic disturbance (dredging) on these distributions. The term “benthic” refers to the collection of organisms living in the substrate at the interface …

Roger Williams Park Edible Forest Garden, Mark S. Scialla
Senior Honors Projects
An edible forest garden is a low-maintenance system that uses edible native and regionally-adapted plants arranged in beneficial relationships to meet human, wildlife and ecosystem needs. The forest garden in Roger Williams Park will transform underutilized urban land into a highly productive parcel producing market-viable fruits, nuts, vegetables, medicine and fiber. Forest gardens mimic natural forest systems in architecture and complexity. The design follows ecological principles to create a system that promotes biodiversity and enhances the surrounding ecosystem. This project also demonstrates the potential to grow food and create land-based livelihoods in the city.
Located on the edge of a …
The Paper Trail: Paper Use And Disposal At The University Of Rhode Island, Katherine Modzelewski
The Paper Trail: Paper Use And Disposal At The University Of Rhode Island, Katherine Modzelewski
Senior Honors Projects
The University of Rhode Island has a well-established recycling program, however, the university community does not make full and proper use of the services and facilities provided. This project will specifically look at the use and disposal of paper products that are used for business and educational purposes at the University of Rhode Island and the effects these practices have both up- and down-stream. This analysis will be accomplished by examining the source and disposal of these university-used paper products through interviews with knowledgeable individuals, including those with oversight on the ordering, management, and disposal of professional paper products, a …
