Testudinidae In a study involving captive Mediterranean tortoises (Testudo graeca and T. hermanni) blood glucose values were found to have a statistically significant peak in April and in May upon emergence from hibernation . This sudden peak of glucose may act as a trigger for arousal, and may be associated with a rise in environmental temperature. This elevated blood glucose provides a readily available energy source for tortoises until they begin to feed again. In another study involving hibernating reptiles the level of glycemia in the winter was inversely correlated with the amount of glycogen stored in the liver . Fresh-water turtles were found to show a marked hyperglycemia when diving, which is probably related to increased anaerobic metabolism . Other studies indicate reptiles may exhibit hyperglycemia of several days’ duration after a meal . In a laboratory setting, 2 months of starvation at approximately 70 F (21 C) was necessary before blood-sugar levels become hypoglycemic.
