Abstract
Captive adult male chacma baboons (Papio ursinus) housed with natural lighting exposure and blood sampled at 3‐hr intervals showed significant diurnal variations in serum testosterone concentrations. Low mean concentrations were found at 0800 hr approximately 1 hr after sunrise and mean concentrations were their highest at 2000 hr approximately 1 ¼ hr after sunset.
