Comparative Lifecycle and Toxicity Testing of Multiple Mayfly Species Across a Gradient of Total Dissolved Solids, With Methods Development for Native Species in the Central Appalachian Coal Fields

800 532 Stroud Water Research Center

Many water quality standards for pollutants in streams are based on laboratory toxicity tests that rely on macroinvertebrate species that are easy to handle in the laboratory. Unfortunately, these standard…

Water Quality Assessment in California Using DNA Barcoding

800 532 Stroud Water Research Center

This pilot study was designed to test how the use of a new technology called DNA barcoding can improve water quality assessment in California streams by enabling researchers to identify…

Macroinvertebrate Assessment of Environmental Conditions in Four Tributaries on the Red Clay Reservation

800 532 Stroud Water Research Center

Stroud Water Research Center scientists sampled stream macroinvertebrates (i.e., primarily insects, crayfish, and worms) and baseflow water chemistry to assess stream condition as a cumulative measure of the effects of…

Spatial and Temporal Variation in Water Quality Among Major Tributaries of the Schuylkill River

800 532 Stroud Water Research Center

This research, education, and outreach project continues efforts with local watershed groups to monitor macroinvertebrates in streams throughout the Schuylkill River Basin, which is located in the Northern Piedmont and…

Evaluating the Seasonal Effects of Short-Term Temperature Change on Macroinvertebrates and Fish in Streams and Rivers

800 532 Stroud Water Research Center

We are conducting laboratory studies to test criteria of existing legislation for protecting fish and macroinvertebrates from excessive temperature changes during a 24-hour period in both winter and summer. Funded…

Effects of Land Use on Water Quality of Streams and Rivers on the Osa Peninsula, Costa Rica

800 532 Stroud Water Research Center

We used species composition and relative abundance of aquatic insect populations to measure water quality changes from deforestation, cattle farming and palm oil plantations in seven streams and rivers in…
