Abstract: Lay Summary Being dominant often comes with the privilege of priority of access to good food that can boost individual energetic condition and enhance reproductive success. Using data from female mountain gorillas in Rwanda, we show that dominant individuals are more aggressive and spend more time at a food site, but overall they do not incur higher energy intake. The previously demonstrated higher reproductive success of dominant individuals can thus not be explained by energetic benefits.
