Ecotoxicity Study for Mayflies Exposed to Ambient Stream Water From the Upper Delaware Basin and to Produced Water From Natural Gas Drilling

 800 532 Stroud Water Research Center

The production of natural gas from the Marcellus shale in Pennsylvania results in water that travels up through the well bore. This water generally has high concentrations of various salts…

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…

Long-Term Research in Environmental Biology (LTREB): Dynamics of Stream Ecosystem Responses Across Gradients of Reforestation and Changing Climate in a Tropical Dry Forest

 800 532 Stroud Water Research Center

Stroud Water Research Center has expanded on 20 years of research on tropical streams near the Maritza Biological Station in northwest Costa Rica, which provides the framework of this study,…
