    , and habitat parameters were sampled during May, July, and September 1997. No significant differences (P>0.05; F<4.2; df=2,9) in densities or catch-per-unit-effort among sample periods were detected for macroinvertebrates. CopepodacopepodaSubject Category: Organism Names

    spp. densities showed significant changes (P<0.03; F>6.1; df=2,9) and collectively surpassed 3200 organisms/litre. These densities exceeded other regional means by as much as 900%. Twentyfour fish species were documented in the wetland; however, Ameiurus melasameiurus melasSubject Category: Organism Names

    dominated the fish community. Wetland depth and surface area increased during the connection period and inundated terrestrial grasses and woody debris. Decay of submerged organic matter, combined with the lack of rooted macrophytes, loss of algal productivity to flushing, and higher turbidity, may have all contributed to reduced summer dissolved oxygen levels. Avian feeding activity suggested that fishes were using the upper water column when nearly anoxic lower water column conditions existed. Although the wetland habitat may be harsh, presence of juvenile fishes and dense zooplankton populations establishes the potential importance of these water bodies to the Missouri River ecosystem.
