Fig. 8. Results of multivariate principal component analysis of the differences between membrane glycerophospholipid compositions in thoracic muscles and fat body tissues of Pyrrhocoris apterus sampled in the field (23 October and 27 December) or variously acclimated in the laboratory (initial state, diapause progression, desiccation, cold acclimation). (A) The centres of elipses represent the means, and the borders the standard errors, of the scores from the first and second principal component. The dashed line separates the data for muscles and fat-body tissues. (B,C) The differences among the scores of PC1 and PC2, respectively, were tested using one-way ANOVA followed by a Student–Newman–Keuls test (different letters indicate statistically different values).
