There were also significant differences in total abundance among stations (Fig. 5, F = 2.31714,88, P = 0.009); however, post hoc tests showed that this difference was driven by a station at the mouth of Narragansett Bay (station 8) which had very low total abundance (e.g. station 8 versus station 10 P = 0.03, all other comparisons not involving station 8 P > 0.4).
