Results from 13C–HCO3− and 15N–N2 isotope probing experiments: a Carbon and b dinitrogen fixation by the microbial symbionts (nmol C (or N) g gill tissue−1 h−1 ± SE, n = 5). Sampling points are color-coded in purple (April) and cyan (October). Different lowercase letters indicate significant differences (p < 0.05, PERMANOVA)
