  Description:
    Abstract:
      Eighteen species of native unionid mussels (Unionidae) were
      recovered from sediments dredged from behind a coffer dam built
      during the construction of the Melvin Price Lock and Dam on the
      Upper Mississippi River. For three species (Amblema plicata,
      Anodonta grandis, and Obliquaria reflexa), shells in the dredged
      material were significantly smaller than those of the same species
      collected at about the same time from the other sites in Pool 26 of
      the Illinois and Mississippi Rivers. The concentration of juvenile
      specimens in the dredged material is thought to represent a de novo
      development associated with silt accumulation behind the coffer dam.
    Purpose: Reporting results of research.
