The endangered Barbary macaques have to cope with extreme environmental conditions, from cold and snowy winters to hot and dry summers. Under these extreme and diverse ecological conditions full-filling their daily energetic requirements may be very difficult for macaques. We have recently published a study that analyse the metabolic strategies of Barbary macaques in response to various ecological challenges. Below are the link to the paper and the graphical abstract.
