Past Projects

Tools like Marxan can help identify the balance of land uses that support the co-existence of nature and people.

We compared macroinvertebrate assemblages before and after Flaming Gorge Dam was built and along a longitudinal gradient below the dam to determine how tributaries influenced recovery. Species richness increased 70 km downstream of the dam but did not ful...

We quantified responses of macroinvertebrate drift, benthic assemblages and fish consumption to the number of hydrologic releases a day and a month from Flaming Gorge Dam. Number of hydrologic releases had larger impacts on resource availability for fish

We assessed the effects of rotenone, a piscicide, on zooplankton and macroinvertebrates in the Uinta mountains using a before-after-control-impact study. Zooplankton recovery was quicker than macroinvertebrates, but observed assemblage shifts have the pot...

In collaboration with UT DWR, BLM, USFS, and other agencies, we compared Bonneville cutthroat trout responses among paired grazed and ungrazed reaches with variable management. Recovery post-grazing was primarily driven by grazing regime, geomorphic chan

We characterized oviposition habitat selection by macroinvertebrates in the Green River below Flaming Gorge Dam, and to quantified the extent to which dam operations alter oviposition habitats and subsequent recruitment success. Eggs were laid in regions
