From: Clownfish in hypoxic anemones replenish host O2 at only localised scales
Oxygen levels (% air saturation) measured at a distance of (A) 0.2 cm, (B) 1.2 cm and (C) 2.2 cm above the surface of E. quadricolor, either in the absence of A. frenatus (closed symbol and solid line) or with A. frenatus present (open symbol and dashed line), at 3 different light intensity levels (PFD = 0, 55 and 110 µmol m−2 s−1). Data are average values ± 95% CI. Dissimilar letters indicate a significant difference (P < 0.05). N = 8 anemone and 8 clownfish (i.e. 8 separate pairings) using a repeated measures approach across the 3 distances and 3 light intensity levels.
