Determining the effects of wetlands on the dispersal of zebra mussels in coupled lake-stream systems

Stream flow is a major vector for zebra mussel spread among inland   lakes. Veligers have been found tens to hundreds of km from upstream   source lakes in unvegetated stream and river systems. It has been   suggested, however, that the downstream transport of zebra mussels   is restricted by wetland ecosystems. Veliger abundance, recruitment   and adult mussels were surveyed in four lake-wetland systems in   southeastern Michigan, U.S.A. from May to August 2  6. Sampling was   conducted downstream of the lakes invaded by zebra mussels,   beginning at the upstream edge of aquatic vegetation and continuing   downstream through the wetland streams.    Veliger abundance decreased rapidly in vegetated waterways compared   to previously reported rates of decrease in non-vegetated streams.   Veligers were rarely found more than 1 km downstream from where   vegetation began. Newly recruited individuals and adults were   extremely rare beyond open water in the wetland systems. Densely   vegetated aquatic ecosystems limit the dispersal of zebra mussels   downstream from invaded sources. Natural, remediated and constructed   wetlands may therefore serve as a protective barrier to help prevent   the spread of zebra mussels and other aquatic invasive species to   other lakes and ecosystems.    (wetland); (wetlands); (AIS); (aquatic invasive species); (ANS);   (aquatic nuisance species); (zebra mussels); (zebra mussel);   (Dreissena polymorpha)
