From: Biogenic volatile release from permafrost thaw is determined by the soil microbial sink
Uptake of volatiles by mineral and organic active layer soils. Mean release rate (n = 6) is shown for a ethanol, c methanol, and e other biogenic volatile organic compounds (BVOCs) from incubations of mineral soil, organic soil, permafrost soil, permafrost+mineral soil, and permafrost+organic soil. The relative uptake by mineral and organic active layer soils of b ethanol, d methanol, and f other BVOCs released by permafrost soils is furthermore presented. Statistically significant P values for the univariate analyses of variance (ANOVA) are shown. In a, c, e, P values from Dunnett’s test represent the difference in BVOC release between permafrost soil (PF) and permafrost+mineral soil (PF+Min) or permafrost+organic soil (PF+Org). In b, d, f, P values represent the effect of soil type on BVOC uptake. Error bars show standard error of the mean
