Fig. 5From: Patterns and dynamics of neutral lipid fatty acids in ants – implications for ecological studiesPrincipal component analysis for changes in composition over time of colonies under the high-fat treatment. Lighter colors mean later weeks. Arrows show fatty acids with significant effects over compositional changes (for factor loadings, see S6 in Additional file 1).
