Integration of Physiological, Life-History, and Macro-Ecological Approaches for Understanding Thermal Limitation in Aquatic Insects: Implications for Freshwater Biodiversity in a Warming World

 800 532 Stroud Water Research Center

In this project, we test the hypothesis that temperature limits the distributions of aquatic insects through its effect on resource allocation, and that warming decreases reproduction by shunting energy away…

Ecotoxicity Study for Mayflies Exposed to Elevated Concentrations of Chloride at Different Temperatures

 800 532 Stroud Water Research Center

Chloride concentrations in surface waters have been increasing over the last several decades at multiple locations throughout the United States. At times, it appears that ambient chloride concentrations now reach…

Oxygen Not Behind Threat To Mayflies When Temps Rise

 800 450 Stroud Water Research Center

When stream temperatures rise, often as a result of climate change or thermal pollution or a lack of tree shade, mayflies display poorer growth.
