Recycling Spent Brewing Yeast As A Shrimp Feed Supplement, John Denvir
Ocean Engineering and Marine Sciences Student Publications
The aquaculture industry relies heavily on commercial fish feed, which accounts for over 50% of production costs and limits farm profitability worldwide[1]. Breweries generate about 3 gallons of high-strength wastewater per gallon of beer produced, much of it discarded as an oxygen-depleting pollutant from spent yeast[2]. Therefore, this project tests recycling spent brewer's yeast into a sustainable fish feed supplement to cut aquaculture costs and divert brewery waste from waterways, promoting circular food systems.

Brevards Microplastics: A Literature Review And Proposed Methods To Study Florida Beaches, Kenna Peters
Ocean Engineering and Marine Sciences Student Publications
With populations along coastlines rapidly increasing so does the risk of microplastics entering the environment. Previous studies have found that 68% of microplastics found in the environment come from man-made cellulosic materials like rayon. Little information is known about the distribution, transportation, and final location of microplastics once they are introduced. Brevard County contains multiple types of beaches that differ substantially in human activity levels, urban density, and land-use patterns. Having a full picture of microplastic distribution and intensity is vital to understanding and reversing the impact these pollutants have on the environment.

Bulletin of Chinese Academy of Sciences (Chinese Version)
As the “stabilizer” of national food security, Northeast China is highly sensitive to climate change. Over the past 60 years, the regional temperature has risen significantly at a rate of 0.034℃/a, which is much higher than the global average of 0.0074℃/a. The improvement of thermal resources has driven a significant northward expansion of high-yield and heat-demanding crops, such as maize and rice. Nevertheless, increased warming has enhanced evapotranspiration demand, which, combined with the expansion of planting scales, has led to a 19.8% increase in agricultural irrigation water consumption over the past 20 years, resulting in a prominent contradiction between supply …

Recent Wetland Elevation Dynamics In Coastal Louisiana, Usa, Elizabeth Harris
LSU Master's Theses
Coastal marshes globally are increasingly vulnerable to accelerating relative sea-level rise (RSLR), which threatens their capacity to maintain elevation through feedbacks among sediment supply, vegetation productivity, hydrology, and soil processes. Although many marshes can persist under moderate rates of sea-level rise through vertical accretion and belowground biomass production, this resilience is strongly constrained by sediment availability and subsurface processes such as autocompaction and organic matter decomposition. High accretion is often assumed to confer marsh resilience; however, subsurface processes, particularly autocompaction driven by surface loading, can substantially offset elevation gains. Coastal Louisiana experiences among the highest rates of RSLR worldwide due …
