Increased activity in a nocturnal primate through lighting manipulation: the case of the Potto Perodicticus potto



The source, intensity and colour of exhibit lighting for Pottos Perodicricus potto were manipulated in a series of four different phases. The new lighting scheme developed led to highly significant increases in the activity levels, behavioural repertoire and visibility to the public. These changes in behaviour provided evidence of an improvement in psychological well-being and greatly enhanced the Pottos' value as exhibit animals.
