Fig. 8. Mol % of non-methylene interrupted dienoic fatty acids (22:2 NMI) in the polar lipids as a function of speciesxdate (A; data from different tissues pooled) and tissuexdate (B; data from different species pooled). Values are measn ± s.e.m, N=2–6 tanks. Data from different overwintering temperatures were pooled as this effect was not significant. Different letters indicate significant differences.
