Sediment Stabilization by Animals in Stream Ecosystems: Consequences for Erosion, Ecosystem Processes, and Biodiversity

1024 681 Stroud Water Research Center

Like underwater engineers, caddisflies and other net-spinning macroinvertebrates attach gravels to one another on the bottom of streams in a way that stabilizes the stream bed and reduces erosion. Using…
