Abstract: "We describe several niche dimensions of Drunella coloradensis Dodds based upon physical and chemical parameters of over 900 stream stations in 11 western states. Nymphs were found at 199 stations and were collected at elevations from near sea level to over 9,000 ft and from streams with a wide range of water discharges. This mayfly showed significant avoidance of streams with <l% channel gradients and those where fine sediments dominated the substrate. Nymphs of D. coloradensis selected for waters with <100 mg/l alkalinity and <50 mg/l sulfate and streams with brush or evergreen trees dominating the riparian vegetation. Drunella coloradensis is intolerant of water quality degradation but moderately tolerant of other changes in the physical habitat. Drunella coloradensis shows divergence from related species through resource partitioning strategies related to water quality tolerances and physical habitat selection."
