Entomology Group

600 400 Stroud Water Research Center

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.
