Fig 9. Untransformed values of colony survival and growth (A and B) and individual worker lean mass and lipid content (C and D). The lines intersect in all graphs, suggesting that both colony level growth and survival, as well as individual level lean and lipid mass, trade-off as a function of the carbohydrate and protein content in the diet (x-axis). In all cases, the lines intersect at the intermediate level (ML or MH) of P:C used in this experiment.
