OverviewAI-generated summary
Shannon L. Speir's research investigates environmental processes within agricultural watersheds, focusing on nutrient transport and ecosystem dynamics. Her work examines how factors such as storm events, land management practices like cover cropping, and hydrologic modifications influence the mobilization and transport of nitrogen and phosphorus.
Speir has studied denitrification rates in ditch sediments and the seasonal differences in relationships between nitrate concentration and these rates. Her investigations also extend to the dietary habits of terrestrial organisms, utilizing stable isotopes to trace food chain pathways, such as the diet of spiders consuming emergent aquatic insects. She has also explored concentration-discharge relationships in watersheds, reviewing methods for their assessment across various temporal scales.
Her scholarly contributions include 78 publications, with an h-index of 13 and over 500 citations. Speir has received federal funding, including a $50,000 NSF grant through the I-Corps program for research on peptoid microsphere-coated surfaces for wound healing. She collaborates with researchers at the University of Arkansas at Fayetteville and the University of Arkansas at Little Rock.
