Spatio-temporal variation in the composition of the bacterial (A), proteobacterial (B), chloroplast (C), and microeukaryotic (D) communities based on 16S (A–C) and 18S (D) rRNA gene sequences. Circles represent the mean proportions of microbial sequences in the three replicates for each sampling site and date. Chloroplast 16S rRNA gene sequences were classified by BLAST on NCBI. Abbreviations: Aug, August; Sept, September.
