Fig. 3. Bar plots with richness, density, and biomass of macroinvertebrates at the two study sites. Includes bar plots of stream 61a and tributary, the fast and slow flowing habitats, and the three biotopes (runs, riffles and pools). Error bars represent standard deviation (Stream 61a n = 6, tributary n = 6, both fast and slow flowing habitats n = 6, runs n = 3, riffle n = 3 and pool n = 6). Significant differences between the fast and slow sites with richness (p = 0.05*).
