Melbourne, Apr 30 : Females of an Australian species of lizard rely on testosterone when they want to put off a male from copulating with her, according to researchers at University of Melbourne.
Evolutionary ecology Dr Devi Stuart-Fox of the University of Melbourne, and colleagues studied the female Lake Eyre dragon lizard (Ctenophorus maculosus) and found that she displays a bright orange belly and throat during parts of her breeding season, which researchers think is driven by the hormone testosterone.
They found that the colour features prominently when the female wants to keep amorous males off their back.
