Replaced with: "Invertebrate biomass densities followed this trend, with a calculated range of 2.5 mg/m2 to 1,000 mg/m2 for tubificids compared to 0 mg/m2 to 200 mg/m2 for chironomids." Removed: "(for example, 1.26 mg/m2 at RM 199 versus 268.4 mg/m2 at RM 44.6)" Replaced with: "(for example, 5.1 mg/m2 at RM 199 versus 1,073.6 mg/m2 at RM 44.6)" July 8, 2010 Posted online at http://pubs.usgs.gov/of/2010/1075/ June 4, 2010 -----------------------------------------------------
