        Aquatic Invasive Species

        Aquatic Invasive Species (AIS) such as quagga or zebra mussels pose a serious threat, both ecologically and economically, to freshwater systems because they reproduce dramatically and can block dams, plug irrigation systems and attach to water craft in a fairly short time.  Methodology for detecting AIS has been somewhat rudimentary, involving visual diagnostics by means of microscopy.  Newer methods are available, but not necessarily in wide use.  This resource will have students learn about these issues and develop a short video or poster that might be used in their area.
