Algal and Macroinvertebrate Responses To Elevated Phosphorus Concentrations in Pennsylvania Streams

 800 532 Stroud Water Research Center

This project took advantage of the unique facilities of Stroud Water Research Center as a field station with first-rate laboratory facilities in an Exceptional Value Watershed and the experience of…

Effects of Elevated and Fluctuating Temperature Regimes on Macroinvertebrate and Fish in Pennsylvania’s Warm Water Streams and Rivers

 800 532 Stroud Water Research Center

This laboratory project investigates macroinvertebrate and fish responses to artificial changes in water temperature. Thermal regimes are warmer than normal and approach or exceed physiological and regulatory limits. Daily temperature…

Dynamics of Organic Particles in River Ecosystems

 800 532 Stroud Water Research Center

Suspended organic particles are important to river food webs and in the transfer of organic carbon from land to ocean. In an experiment conducted in Stroud Water Research Center’s streamside…

Hydrologic Regulation of Dissolved Organic Matter Biogeochemistry From Forests Through River Networks

 800 532 Stroud Water Research Center

This collaborative proposal will generate the mathematical models that simulate stream flow in White Clay Creek and the movement of water carrying dissolved organic carbon from soils to the stream.…

The Application of Scaling Rules to Energy Flow in Stream Ecosystems

 800 532 Stroud Water Research Center

Scientists have grown young deciduous trees in an atmosphere enriched with the stable isotope of carbon so as to follow the fate of those organic molecules in small laboratory reactors,…
