Fig 1.
Survivorship curves and time to loss of equilibrium (LOE) in Bellapiscis medius exposed to severe hypoxia (7% air saturation) after 19 h recovery from acute heat shock.
Blue line = control group (no heat shock), pink line = +8°C heat shock (21–29°C), red line = +10°C heat shock (21–31°C). Inset shows median time to loss of equilibrium and individual data points (N = 12 per treatment group). Different lower case letters in the inset indicate significant differences (P<0.05) in the median time to LOE among treatment groups.
Fig 2.
Critical oxygen saturation (Scrit) and standard metabolic rate (SMR) of Bellapiscis medius following recovery from acute heat shock.
All values represent mean ± S.E.M. A = control (N = 10), B = +8°C heat shock (N = 10), C = +10°C heat shock (N = 8). Triangles show SMR under normoxia, circles show routine under progressive hypoxia exposure, vertical line shows Scrit and vertical dotted line shows Scrit S.E.M. The dashed horizontal line shows the break point between oxygen regulation and oxygen conformation and is for illustrative purposes only.
