Examines the basking postures of captive eastern painted turtles exposed to two different sources of illumination (white floor lamps and infrared heat lamps) and three types of substrates (sphagnum, rock, wood) and discusses possible ecological and evolutionary significance of these behaviors. (Author/JN)

Describes a class project to determine which environmental condition, such as light, heat, and type of basking substrate, would result in the least and most turtle basking behavior. (PR)
