Monitoring Fish Populations and Stream Habitat Quality for the National Park Service

800 532 Stroud Water Research Center

This project monitors biological conditions, water quality, habitat integrity, and fish at 37 sites in 10 national parks in the National Capital Region Network around Washington, D.C. The findings of…

Molecular Ecology of Archaea in Aquatic and Terrestrial Environments

800 532 Stroud Water Research Center

Less is known about Archaea than the other two domains of life on Earth (Bacteria and Eukarya), particularly the role they play in ecosystem functions and nutrient cycling (e.g., ammonia…

Mitigating Agricultural Pollution of Fresh Water and Combating Climate Change by Restoring Soil Health

800 532 Stroud Water Research Center

Plowing, disking, synthetic fertilizers, and pesticides have damaged the health of agricultural soils, resulting in reduced rainfall infiltration and storage, increased stormwater and pollutant runoff, degraded streams, and contaminated groundwater.…

Microbial Population Dynamics of Periphyton Biofilms in White Clay Creek

800 532 Stroud Water Research Center

Using glass microscope slides as tiny gardens to grow microbial biofilms, this project explored differences in microorganisms between three reaches of White Clay Creek with different streamside vegetation. Molecular DNA…

Long-Term Research in Environmental Biology: Trajectory for the Recovery of Stream Ecosystem Structure and Function During Reforestation

800 532 Stroud Water Research Center

Stream restoration in the United States is a multibillion-dollar industry, yet long-term monitoring of its effectiveness is virtually nonexistent. To fill this gap, the Stroud Center restored a portion of…

Impact of Pesticides on Soil and Vegetables Grown in Organic and Conventional Systems in a Long-Term Vegetable System Trial

800 532 Stroud Water Research Center

This project characterizes microbial soil health through detailed community structure of bacteria and fungi and determines the relationship of microbial structure with application of pesticides under conventional and organic cropping…

Impact of Land Management of Practices on Winter Squash Yield and Post-Harvest Nutrient Density

800 532 Stroud Water Research Center

By examining the bacteria, Archaea, and fungi living in soils, this project will provide insights on how farming practices and land management affect the microbes that make soils healthy. This…

Exploring the Link Between Soil and Human Health: Protein, Protein Quality, and the Nutraceutical Amino Acid Ergothioneine

800 532 Stroud Water Research Center

Ergothioneine, an amino acid that has scientifically proven benefits to human health, is exclusively biosynthesized by fungi and certain bacteria in soils. With coupled field testing and lab incubation experiments,…

Evaluating the Effects of Watershed-Scale Agricultural Best Management Practices on Water Quality

800 532 Stroud Water Research Center

In early 2020, stream bank fencing, forested buffers, and barnyard improvements were installed on Amish farms in Lancaster County, Pa. The farms are nested in a small watershed drained by…

Evaluating and Updating Data Collection Protocols in National Parks of the National Capital Region

800 532 Stroud Water Research Center

The National Park Service has monitored stream water quality and quantity for more than 15 years in shallow streams located in 10 parks of the National Capital Region Network. This…
