Results from the second run of the CS experiments, indicating that hypoxia during the embryonic, larval or pupal stage reduced adult mass in male D. melanogaster. Treatment groups: C10, constant 10 kPa PO2; C21, constant 21 kPa PO2; E, embryos exposed to hypoxia; L, larvae exposed to hypoxia; P, pupae exposed to hypoxia. Letters indicate significant difference from constant 21 kPa PO2 (a) or from constant 10 kPa PO2 (b) by an a priori Bonferroni-corrected test.
