Fig. 7From: Variations in the archaeal community and associated methanogenesis in peat profiles of three typical peatland types in ChinaCorrelations between physicochemical properties, archaeal community diversity indices, and abundances of dominant archaea. The depth of the color indicates the strength of each correlation. Red and blue colors indicate negative and positive correlation coefficients, respectively. The circle sizes reflect the significance of correlation coefficients. *, **, *** indicate significant correlation coefficients at p < 0.05, p < 0.01, and p < 0.001, respectively. WC, TC, TN, TP, DOC, and TFe denote peat water content, total carbon content, total nitrogen content, total phosphorus content, dissolved organic carbon, and total Fe content, respectivelyBack to article page
