Natural and simulated insect-substrate relationships in Idaho batholith streams Item Info

Laboratory and field studies were conducted to determine the effects of sediments on the distribution and abundance of insects in Idaho Batholith streams. Changes in characteristics of substrate, e.g. dominant substrate, imbeddedness of dominant substrate, composition of material surrounding dominant substrate, and water velocities were correlated with changes in benthic insect populations. Multiple regression analysis indicated benthic populations were not responsive to sediment introduction until the dominant substrate became heavily imbedded. Species diversity was found to be directly correlated with water velocities below 0.35 m per sec. Sediment introduction upon riffles in a natural stream, indicated that rocks greater than 6.5 cm in size contributed most to species diversity of the riffle. Riffles composed of cobble recovered more rapidly to the pre-treatment species diversity than riffles without cobble.
