Results of PERMANOVAs testing the relative importance of season, station and their interaction on FA and sterol profiles of S. senilis and the Scheirer-Ray-Hare test, testing the correlation of data as a function of season, station and their interaction on δ13C and δ15N values. Significance is indicated by stars: * if p<0.05; ** if p<0.01 and *** if p<0.001; and NS for not significant.
