Fig. 4. Percent of systemic cardiac output (%_sys) distributed between tissues from turtles acclimated at 5°C (A,B) and 21°C (C,D). (A) Routine normoxic control at 5°C, (B) after 12 days of anoxic submergence at 5°C, (C) routine normoxic control at 21°C and (D) after 6 h of anoxic submergence at 21°C. Asterisks indicate significant (P<0.05) tissue specific differences in %_sys between acclimation temperatures in routine normoxic control. Exploded slices signify significant differences (P<0.05) in tissue %_sys between routine normoxia and anoxia within each acclimation temperature. N=6 at 5°C and 5 at 21°C.
