Dynamics of Organic Particles in River Ecosystems

800 532 Stroud Water Research Center

Suspended organic particles are important to river food webs and in the transfer of organic carbon from land to ocean. In an experiment conducted in Stroud Water Research Center’s streamside flumes, researchers verified that biofilms — algae and microbes that coat streambed surfaces — continually trap and release organic particles, thereby controlling their rate of downstream migration. The results of this and other experiments from this project are being used to model the influence of headwater streams on the downstream river network.
