Figure S2. Bacterial and micro-eukaryotic abundances according to time (along with mean temperature and CO2 concentration) (A) or mineral substrate (B). Abundance data are shown as mean log number of 16S rRNA and 18S rRNA genes copies ± standard errors. Quantitative PCR analysis was performed in duplicate. The letters represented the statistical differences between histograms. (PDF 153 kb)
