Abstract

This study was conducted to document the current zooplankton, macroinvertebrate, herpetological, and ichthyofaunal biodiversity of the upper Missouri river and to compare current diversity with historic values. Zooplankton, macroinvertebrates, herpetiles, and fish were collected from two separate riverine. Free-flowing sections of the Upper Missouri River during the spring and summer of 1993. In the Bismarck and Williston study reaches sampling was condicted in seven macrohabitat types: backwaters, side channels, main channel borders, main channels, sandbar complexes, tributary confluences, and vegetated islands. Zooplankton sampling consisted of replicate vertical tows with a plankton net. Macroinvertebrate sampling included a petite ponar dredge for the benthos as well as dipnet smapling. Additionally, the molluskan fauna was sampled through visual observations with the use of a shell bar, and with the petit ponar dredge. Herpetiles were collected through visual observatiosn and with a combination drift fence and funnel trap. Finally, the ichtyofauna was sampled using both active, small-mesh minnow seines, and passive, cloverleaf minnow traps, gear.
