Missouri River Environmental Inventory. Measurements of the Species Diversity of Planktonic and Microbenthic Organisms.

Abstract

This project involved identification of planktonic and benthic organisms, the species diversity, relative abundance and factors limiting micro- and macroscopic organisms presently occupying various water, mud/water and rock substrate habitat sites in the channelized and unchannelized portions of the Missouri River from Yankton, South Dakota to Rulo, Nebraska. Also included in this study are the measurement and description of physical and chemical water quality parameters that are critical to the survival of micro- and macrobenthic groups, and the association of particular benthic groups to major habitat areas found in the river. Water quality parameters include temperature, temperature profiles, dissolved oxygen, turbidity, biological oxygen demand, pH, nitrate (NO3) content, PO4 (ortho and meta phosphate) content, sedimentation rates, and water velocity. Air temperature was another important parameter because the water temperature is largely dependent upon the temperature of the air.
