Figure 1

Temperature dependent oxygen consumption of zoea I (A), zoea II (B) and megalopa larvae (C) of Hyas araneus. Larvae were reared at two different seawater PCO₂ (open circle: controls, 420 μatm CO₂; closed circle: 3300 μatm CO₂; Mean ± SE, N = 5-8). Asterisks indicate significant differences between treatments at the same experimental temperature. Different letters indicate significant differences between temperatures within one treatment (lowercase letters: 420 μatm CO₂; uppercase letters: 3300 μatm CO₂).
