Fig. 5. Length- frequency distributions of macroinvertebrates among stream 61a and its tributary, fast and slow biotopes, and among 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 found between the fast and slow sites (p = 0.04*), pool and runs (p = 0.01**) and riffles and runs (p = 0.01**) using Kolmogorov-Smirnov test.
