Fig. 6: Diel temperature responses of heterotrophic and autotrophic respiration.
From: Bimodal diel pattern in peatland ecosystem respiration rebuts uniform temperature response
Exponential regression relationships between a–d heterotrophic respiration (Rh) and e–h autotrophic respiration (Ra) and air temperature (Ta) for day- and nighttime (i.e., photosynthetic photon flux density ≥ 20 and <20 μmols m−2 s−1, respectively) during the key phenophases of green-up, peak season, senescence, and dormancy (spring and autumn) shown as a mean of the years 2015–2016. Values shown in the panels (blue and gray for day- and nighttime periods, respectively) represent model parameters R10 and E0 with standard errors in brackets from the Lloyd & Taylor14 respiration model (see equation in Methods). Solid lines indicate the exponential fit and shaded bands indicate the 95% confidence intervals.
