Figure 2. Ion balance of turtles (Chrysemys picta picta) at 3 °C.
Measured data (from Ultsch et al. 1999) were collected from normoxic animals (control) and from animals after 125 days of submergence (anoxic observed). The hypothetical result of the same increase in lactic acid with no supplemental buffering response is also shown (anoxic uncompensated), in which much of the acid is unbuffered.
