Appendix B. Size frequency histograms of mussels for each survey site and period.

 
   FIG. B1. Size frequency distributions of Mytilus edulis for each site and sampling period for which mussels were present. Mean length mm (with sample size in parentheses), is reported above each histogram. Small sample size in Fall 2001 at some sites is due to paucity of live mussels following hypoxic die-off. Significant difference in mean size from previous sampling period is indicated by *** P < 0.001, ****P < 0.0001.
