Fig. 4. Daily mass-specific mass loss rates (mean ± S.E.M.) as a function of time from initiation of measurements at 30°C and 50%RH. Letters represent statistically significant differences (one-way ANOVA on mass-adjusted MLR; =0.05) between day 2 and between averaged days 8–14 MLR values. The filled area represents the estimated maximal dry-mass loss as a result of metabolism, based on carbohydrate catabolism and an oxygen consumption rate of 0.1 ml g^–1 h^–1 (see text).
