Water is found in many places beyond stream channels throughout the watershed. Streamwater, groundwater, soil water, and water in sediments below the channel contain a rich array of organic carbon molecules important as food for microorganisms and as resources for other living things. This laboratory works on identifying the presence of these molecules and determining their role in the stream ecosystem.

Healthy streams often support 200 - 300+ species of aquatic insects, crustaceans and other invertebrates, forming a rich and complex biological community. This laboratory studies factors that affect the distribution and abundance of aquatic invertebrates, the functional role of invertebrates in stream and river ecosystems, and how these invertebrate communities respond to human activities in temperate and tropical watersheds.

Stroud Water Research Center’s campus is a complex of laboratories, offices, meeting spaces, and libraries. Outside, projects are spread over a 1,800-acre experimental watershed. Building equipment, maintaining laboratory systems, planting trees in research plots, and general maintenance of this facility are done by a dedicated and hard working group of people.

Fish Molecular Ecology

The Fish Molecular Ecology Laboratory combines genetic and ecological techniques to study and protect freshwater fish and other aquatic organisms. We use modern genetic technology to learn how genetic diversity is distributed within and among populations of fish and other aquatic organisms, and we conduct field and laboratory studies to learn about natural and anthropogenic factors affecting their distribution and fitness. Our aim is to learn about the role of population structure in the evolutionary adaptation of fish and aquatic organisms in order to promote their long-term protection.

Fluvial Geomorphology

Water and sediment interact to create river channel habitats, floodplains and other elements of the physical riverscape that form the basis of river ecosystems. Our lab studies the movement of water, sediment, organic matter, nutrients and other molecules through watersheds to better understand watershed hydrology, geomorphology and biogeochemistry. We also investigate how watershed land use and river channel restoration practices influence hydrologically mediated processes such as surface-groundwater interaction, sediment transport, and channel evolution.

Information Services

The Information Services group at the Center is involved with computer services and support; network administration; and data management and analysis for the entire Center. We use SAS (SAS Institute, Inc., Cary, NC) as our primary data management and analysis software which involves everything from instrument data capture and data calibration, parametric/non-parametric/univariate/multivariate data analyses; and tabular/graphical output. We also provide Geographic Information Services support to the entire Center from GIS data compiling and analysis to producing maps for reports and publications.

Microbial life such as bacteria, fungi, and algae are integral to a naturally functioning aquatic ecosystem. By applying comprehensive molecular approaches, this laboratory is focused on characterizing the composition and distribution of microbial communities, and determining the functional roles as well as their interactions with environments.

Organic and Isotope Geochemistry

The complex mixture of organic molecules in streams and rivers holds clues about a wide variety of natural and human processes occurring within watersheds. By determining the identity and origin of these molecules, the scientists in this laboratory can both expand scientific understanding of natural cycles of energy (carbon) and nutrients within the ecosystem and inform decision-makers about the sources and impact of human contamination on water quality.
