Dolphin social phenotypes vary in response to food availability but not the North Atlantic Oscillation index
Social behaviours can allow individuals to flexibly respond to environmental change, potentially buffering adverse effects. However, individuals may respond differently to the same environmental stimulus, complicating predictions for population-level response to environmental change. Here, we show t...

Social behaviours can allow individuals to flexibly respond to environmental change, potentially buffering adverse effects.
