Cardiovascular control in cold-acclimated freshwater turtles during chronic anoxic exposure is not well understood. We tested the hypothesis that the observed bradycardia in Trachemys scripta results from increased cholinergic inhibitory tone and reduced sympathetic activity. Cardiovascular status was measured in vivo in turtles acclimated to either 22 degrees C or 5 degrees C and either acutely exposed (6 h) to anoxia at 22 degrees C or chronically exposed (22 days) to anoxia at 5 degrees C… CONTINUE READING
