A Downcore comparison of fixation index (FST) values between core triplicates of abyssal site A7, for each of the four main clades. Comparison between the same sediment layers from different cores is colored according to MAG amoA clade and comparison between different horizons of the same core in red. B MAG mean coverage in each sediment layer of the triplicate A7 cores, illustrated by circle size and clarified as mean ± standard deviation. C Percentage of single nucleotide variants (SNV) identified as variable positions in both samples when comparing similar sediment layers originating from different cores, and percentage of these shared SNVs presenting the same consensus nucleotide. D Mean SNV density in each sediment layer, summarized as mean ± standard deviation. MAGs considered for this analysis are the same as in Fig. 3: HAK_Bin_00079 for clade amoA-NP-gamma-2.1, HAS_Bin_00039 for clade amoA-NP-gamma-2.2, H3T_Bin_00024 for clade amoA-NP-delta, and A9S_Bin_00032 for clade amoA-NP-theta.
