Extended Data Fig. 6: Comparisons of apparent temperature sensitivity (Q10) of soil respiration (Rs) and potential heterotrophic respiration (Rhp) between collapsed and non-collapsed areas at the Shaliuhe site.
From: Enhanced response of soil respiration to experimental warming upon thermokarst formation
a,b, Apparent Q10 of Rs during the growing season in 2019 (a) and 2020 (b). c,d, Apparent Q10 of Rhp during the growing season in 2019 (c) and 2020 (d). Apparent Q10 was estimated for each gully by fitting the seasonal observations of soil CO2 flux and soil temperature in the top 10 cm (see Supplementary Note 1 for detailed calculation). Data are presented with mean values ± s.e.m. (n = 3). Significant differences between collapsed and non-collapsed areas were determined based on linear mixed-effects model with one-sided F tests. **, P < 0.01.
