Macroinvertebrate community structure of three prairie streams

Macroinvertebrate communities of three Great Plains streams were characteri zed. Detailed species lists were obtained through a variety of sampling tec hniques; 105 taxa were identified from the Niobrara River at Agate Fossil B eds National Monument in northwest Nebraska, 77 from Cub Creel; at Homestea d National Monument in southeast Nebraska, and 59 from Pipestone Creek at P ipestone National Monument in southwest Minnesota. Macroinvertebrate densit y, taxa, diversity, and functional group composition were analyzed from qua rterly quantitative samples. All three streams were dominated by collector functional feeding groups.
