Variations in aquatic community framework: Decreases in DO degrees can cause changes in the types and quantities of aquatic macroinvertebrates in surface area waters. Species which might be intolerant of small DO contain some species of mayflies, stoneflies, caddisflies and beetles. As DO concentrations reduce, these organisms generally are changed by tolerant worms and fly larvae.
