A total of 267 samples were grouped into 80 lake-time groups based on sampling sites and collection dates. For subsequent analysis, 26 lake-time groups with more than 3 samples (Nt ≥ 3) and at least two MGC-containing samples (Nmtb ≥ 2) were selected. The ratio of recruited reads to total metagenomic reads served as a proxy for the abundance of the MGC-containing community in each sample. Within each lake-time group, the sampled layer with the highest MTB abundance was considered the optimal niche for the corresponding MTB community (Figs. S2 and S3). The map shows the geographical distribution of the 26 lake-time groups, with pie charts indicating the relative abundances of the MTB community in these groups.
