The role of diet in glycogen storage by juvenile bullfrogs prior to overwintering.
Juvenile bullfrogs from natural populations doubled their glycogen stores during their predormancy period, while their blood glucose and lipid stores declined. Glycogen stores were replenished in natural populations as food consumption decreased. Some liver glycogen was stored during fasting if the bullfrogs were collected in the storage phase of their energy reserve cycle, but the amount of glycogen stored was increased by feeding.
