This study evaluates the functional organization of stream fish assemblages in response to streamflow factors and biotic interactions across a range of spatial scale. The study area for this project includes 109 stream reaches located on tributaries to the upper Missouri River in the northern Great Plains. Fish distribution data...
Fish assemblage structure was determined along a longitudinal
gradient for three drainages in the upper John Day basin: Middle
Fork, South Fork, and upper Mainstem proper. One or two tributaries
in each drainage were included. Where possible, sites were paired:
those with good versus those with poor riparian habitat. Detrended...
