Stream mesocosm experiment investigating invertebrate community responses to disturbance

In this study, we used a stream channel experiment to test the effects of community type and disturbance type on invertebrate communities, with invertebrate drift measurements used as a diagnostic tool to assess community impacts.

Three community types (undisturbed spring, flood-disturbed and agriculture-disturbed) were each established in a recirculating colonist header tank. Each tank fed five stream channels, randomly assigned to disturbance treatments: an undisturbed control, high-flow, nutrients, sediment, and a combined sediment and nutrients treatment.

Data set includes invertebrate community abundances in drift samples and in the channels at the end of the experiment.
