(A) Taxonomic composition of foraminiferal assemblages in twelve SYBH sites based on the proportion of reads. (B) We picked out all OTUs in SYBH which had an identity percentage with the reference database more than 99% and no less than 10 reads and merged those attributed to the same taxa. As a result, we retained 27 OTUs which were assigned to 15 species: Ammonia catesbyana (AMM), Boderia sp. (BOD), Bolivina sp. (BOL1), Bolivina variabilis (BOL2), Heterostegina depressa (HET), Micrometula hyalostriata (MIC), Monothalamiids_XXX_sp. (MON), Nemogullmia sp. (NEM), Parasorites sp. (PAR), Rosalina sp. (ROS1), Rosalina vilardeboana (ROS2), Saccamminidae_X_sp. (SAC), Sorites sp. (SOR), Trochammina hadai (TRO) and Vanhoeffenella sp. (VAN). The proportions of the 15 foraminiferal species in twelve SYBH sites were shown in Fig. 5B which was drawn using the statnet package61 and circlize package62 based on the number of reads.
