Fig. 8. Mussel tenacity vs thread production. Thread production values are
the least square means (± s.e.m.) of pooled data from each simulated
wave action experiment. Tenacity in the corresponding months was estimated as
mean (± s.e.m.) of 6 years of measurements at Bass Rock (see text for
details). A linear regression of the data was not significant
(P=0.18, r2=0.24;
y=0.17x+8.89).
