Desiccation Rates and Temperature Relationships of Terrapene ornata Following Scute Removal

Abstract

Following scute removal, Terrapene ornata desiccates at a greater rate than normal animals with scutes. Experimental animals with all their scutes removed lose about 26% of their initial weight after six days of desiccation: controls lose 3%. Terrapene without scutes and exposed to direct sunlight warm slower than controls. In addition, experimental animals without scutes lose heat faster on cooling. The scutes of turtles retard water loss through the bone and aid in temperature regulation.
