A Snail, a Clam, and the River Jordan

Two invasive mollusks now dominate ecosystem function and water quality in the now novel Jordan River

Full Abstract
For better or worse, the invasive ‘good luck’ clam, Corbicula fluminea and New Zealand mudsnail, Potamopyrgus antipodarum are well established in the Jordan River, UT. Both the snail and the clam reach some of the highest densities recorded (>>5000 m-2 for Corbicula; 250,000 to 500,000 m-2 for Potamopyrgus). Based on literature review presented in this report and recent mollusk surveys conducted in the Jordan River by OreoHelix Consulting and the Wasatch Front Water Quality Council; Corbicula and Potamopyrgus are undoubtedly the most important and dominant biota in the now novel Jordan River ecosystem and together co-regulate seasonal nitrogen, phosphorus, and carbon cycling, microbial community structure, and stream metabolism. The snail and clam are almost certainly seasonally controlling most other ecosystem functions as well, (e.g. water quality), despite their roles being unnoticed to most researchers and managers.
