The Entomology Group 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.

Saving Streams With Good Science
Building trust in the scientific process starts with communicating our research to non-scientists. To that end, our scientists share snapshots of three long-term experiments.

Stroud Center Science Informed Fracking Ban Decision
The accidental release of hydraulic fracking wastewater into streams, even a single drop mixed with 100 drops of streamwater, will harm or kill aquatic insects and even certain fish species.

Oxygen Not Behind Threat To Mayflies When Temps Rise
When stream temperatures rise, often as a result of climate change or thermal pollution or a lack of tree shade, mayflies display poorer growth.
