Hibernation of the Lizard, Anolis carolinensis

Abstract

Summary In late summer and fall, body weight and to a greater extent liver weight increase due to the storage of glycogen and fat. With ithe increased storage of liver glycogen the blood glucose falls to a low level. In the winter and spring the blood sugar rises to a maximum and the liver glycogen and total lipids fall as the animal uses its body stores. Neither varying the hours of light to which the animals were exposed nor keeping them at a constant temperature throughout the year had any marked effect upon the constituents analyzed.
