The dataset includes net and gross primary production, respiration and epiphyte load on the brown algae Fucus vesiculosus under a temperature gradient (5-25 ºC). Under the same temperature gradient, we present physiological responses of Idotea balthica, i.e. respiration, feces production, growth and carbon consumption.
