title: Calcium balance in Drakensberg crag lizards (Pseudocordylus melanotus melanotus; Cordylidae).
abstract: Eight nonreproductive female Drakensberg crag lizards (Pseudocordylus melanotus melanotus) were each fed diets of mealworms and calcium capsules with various calcium levels. Excreta were collected and analyzed for calcium and uric acid content. The amount of calcium in the feces was calculated. The lizards appeared to be able to maintain calcium balance at calcium intakes equivalent to 1.4-5.6% calcium in the dry matter of feed. Calcium balance was maintained by adapting intestinal calcium absorption.
