(a) Symbiont identity significantly affected gross photosynthesis rates yet (b) host genotype moderated the response to temperature. (c) Respiration rates varied with symbiont identity in response to temperature. (d) Photosynthesis to respiration (P:R) ratios across temperature increments for H2‐Hawaii, CC7‐North Carolina, and RS‐Red Sea Aiptasia harboring different Symbiodiniaceae taxa. All response variables are shown as mean values ±1 SE. Pairwise comparisons were carried out within each temperature increment. Letters next to data points indicate similarities (e.g., AA) or differences (e.g., AB) between host and/or symbiont types, as determined by estimated marginal means. Sample size (n) for each case is indicated in the legend
