Fig. 4: Activity of Canton-S and Oregon-R D.m. after 2.5 h of N2-induced hypoxia.

a Heatmap displaying the activity of Canton-S D.m. and b Oregon-R D.m. after 2.5 h of severe hypoxia (<0.3% O2) or normoxia (21% O2). Each cell shows the absolute value of beam crosses per hour, which is represented by color (black: little to no activity, red: moderate activity, green: high activity), as indicated in the legend. Flies were transferred into the DAM system immediately after being subjected to hypoxia/normoxia, and the activity was recorded for the following 120 h. Data were obtained from 3 independent experiments including a total of 180 male flies per genotype for each treatment.
