Appendix D. A table of sea star sizes at mussel and non-mussel sites.

TABLE D1. A table of sea star sizes at mussel and non-mussel sites. The radius of stars was significantly greater (F1 = 235.04, P < 0.0001) at mussel sites than non-mussel sites suggesting mussels supported larger individuals and/or growth rates. ISS = insufficient sample size due to paucity of animals at site.
