When the temperature increases, so do the energetic requirements of species. We find that the energetic stress caused by increases in temperature pushes fish species to consume the first prey they encounter to fulfil their immediate needs, rather than focusing on more energetically rewarding prey. This behaviour increases the vulnerability of communities to climate change.
