Fig. 2: The relationship between the response ratio (lnRR) of particulate and mineral-associated organic carbon (POC and MAOC) content with the lnRR of potential driving factors under warming.
From: Short-term warming supports mineral-associated carbon accrual in abandoned croplands
a, c The relative importance of the lnRR of influencing factors in affecting the lnRR of POC and MAOC content derived by Random Forest model. b Relationship between the lnRR of POC content and the lnRR of root biomass (RB). d Relationship between the lnRR of MAOC content and the lnRR of microbial necromass carbon (MNC). POC aromatic degradation: bacteria involved in aromatic compound degradation of POC; Fed and Feo: pedogenic iron oxides and poorly crystalline iron oxides; SM: soil moisture. n = 12, where the POC aromatic degradation, POC fungal Shannon, and MAOC fungal saprotroph parameters represent composite samples of the sampling sites, and the other parameters represent the mean values of replicate samples from the sampling sites.
