Macroinvertebrate drift along an elevational and stream size gradient in a southern Appalachian stream
Drift was measured monthly at four sites on a southern Appalachian stream in order to examine spatial and temporal patterns along elevational and stream size gradients. Measurements consisted of four, one-hour samples corresponding to dawn, mid-day, dusk, and mid-night monthly for 14 months. On …

Recreational disturbance of a desert stream fish community: Detecting ecological effects of environmental impact
… Food availability measured as algal biomass and macroinvertebrate drift density was similar among all pools, but abundance of larval fish was lower in pools experiencing recreational disturbance. Flash floods at the end of the summer appeared to "reset" the system, redistributing fish in the …

Spatiotemporal Variation in Dispersal as a Driver of Macroinvertebrate Metacommunity Dynamics
… forces. The mechanisms governing freshwater macroinvertebrates community assemblage have long been studied due these organism's ubiquity, diversity, and sensitivity to environmental stressors. Macroinvertebrates reliance on river networks for their larval stages also makes their dispersal …
