Fig. 4: Temperature normalized (20 °C) diel rates of ecosystem respiration (20δ18O2-ER) from dual δ18O2 and O2 model compared to diel ERO2 rates from O2–only model.

20δ18O2-ER rates from dual δ18O2 and O2 model (solid bars) compared to ERO2 (patterned bars) estimated with O2-only metabolism models that assume ER is constant over 24-h. Labels indicate the magnitude of the difference between 20δ18O2-ER and ERO2 for each site. Black bars indicate ±1 SD of posterior model estimates.
