There may have been small shifts in community structure following floods (e.g., [ILLUSTRATION FOR FIGURE 5 OMITTED]: increased relative importance of plecopteran
shredders; [ILLUSTRATION FOR FIGURE 6 OMITTED]: shifts in ordinate position before and after floods).
Also in Indiana, Brack (1985) found dipterans, trichopterans, coleopterans (including the Asiatic oak weevil), lepidopterans, homopterans, hymenopterans, neuropterans, and plecopterans
represented, in decreasing order of importance, in the diet of this species.
genera) of ephemeropterans (mayflies), plecopterans
(stoneflies), and trichopterans (caddisflies) in the sample.
The fauna basically consists of omnivores, generally small rapidly growing animals with short life cycles that usually undergo population explosions when melting occurs and are a source of food for predators, mainly plecopterans
The presence of dipterous larvae and filamentous green algae was evident during the dry months, while invertebrates as trichopterans, plecopterans
, copepods and ostracods occurred during the rainy months.
