Fig. 1From: Vertically stratified methane, nitrogen and sulphur cycling and coupling mechanisms in mangrove sediment microbiomesAssociations between environmental factors and functions of mangrove sediment microbiomes. Mantel tests revealed the correlation between environmental factors and CH4/N/S cycling gene families (A), or functional diversity (B). C The importance of individual environmental factors to a specific metabolic pathway involved in CH4/N/S cycling was calculated using the maximal information coefficient (MIC) index. The percentage refers to the percentage of gene families involved in the specific metabolic pathway significantly driven by environmental factors.
