Results <br />Nematoda <br />Nematodes occured in every sample processed and were most abundant in the July <br />sample of the ephemeral side channel habitat (302,603/m2) and least abundant in the river <br />channel August sample (2421/m) (Fig. 5). They comprised the majority of benthic <br />invertebrates in all habitat types and sample dates except the August river channel and <br />river backwater habitats and the in July sample of the seasonally inundated wetland. <br />Oli ochaeta <br />Oligochaetes were present in all habitat types and during all sample dates. <br />Densities ranged from a low of 2728/m2 in the June ephemeral side channel sample to <br />a high of 164,731/m2 in the July river backwater sample (60x greater) (Fig. 5). <br />Cerat= onidae <br />Ceratopogonids were at their lowest density during the July river backwater <br />sample (96/m2) and were 136x greater in the river channel August sample (13,026/m2) <br />(Fig. 5). Ceratopogonids were absent from both June and July samples of the seasonally <br />inundated wetland and the ephemeral side channel. <br />Chironomidae <br />A total of 19 chironomid genera were collected from all samples. Fourteen <br />genera were found in the July seasonally inundated wetland and five genera from the <br />August river channel and river backwater samples. Seven genera were unique to a <br />specific sample site and date. Six genera were found only in the seasonally inundated <br />wetland habitat and four only in the river channel. No chironomid genus was unique to <br />10
