 | | We designed an experiment in experimental streams to measure the ecosystem response to different flooding frequencies and the presence or absence of southern redbelly dace (Phoxinus erythrogaster), a grazing minnow. |
 | | The two principle response variables were stream metabolism and nutrient retention, but we also quantified algal filament length, algal biomass, algal community composition, invertebrate community composition, and fractionation of benthic organic matter. |
 | | Preliminary results suggest ecosystem processes in prairie streams are dually controlled by grazing and flooding, but floods facilitate the control of algae by grazing minnows. |
