Abstract |
Streams of the arid and semi-arid regions of the western United States are characterized by irregular flow patterns resulting in highly unstable macroinvertebrate habitats and a sparse macrobenthic fauna. The use of a standard square-foot Surber stream-bottom sampler is of limited utility in these regions due to the combined effects of faunal paucity and patchiness. The efficiency of a unit-effort traveling kick method was compared with that of a standard Surber sampler in uniform fauna-poor riffles on the White River, Utah. Comparisons of 50 kick samples with 40 Surber samples revealed that kick samples provided more highly reproducible data than Surber samples in terms of counts of individuals and taxa, percentages of composition, and diversity indices. Visual preselection of the richest sites, however, improved the reliability of Surber sampler data. |
