Extended Data Fig. 1: Effects of warming, altered precipitation, and clipping on total soil C content.
From: Drought amplifies warming-induced soil carbon loss in a decade-long experiment
(a) Mean soil C content in response to warming, drought, wet and clipping from 2009 to 2020. The data of 552 samples were pooled across all measured years, and each bar shows the mean plus standard error (SE). There was a significant warming effect on soil C content (P < 0.050). Thus, the percent change by warming is labeled above the bars. (b) Warming effect on total soil C under different precipitation levels each year. The warming effect was assessed as (value under warming) minus (value under ambient temperature) at corresponding precipitation levels. The error bar represents mean ± S.E.M. (n = 8, 4 clipped+4 unclipped).
