Figure 3

Temperature dependent maxilliped beat rate of zoea I (A) and zoea II (B) 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 = 4-6). 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).
