Table 2. Diversity measures based on sequencing data.

Number of sequences, sample-specific number of OTUs, species richness estimates Chao1 and diversity indices calculated for each sample.

Sample ID	Number of sequences*	Number of OTUs	Phylogenetic diversity whole tree	Richness estimation (Chao1 97%)	Shannon index (H)
CO1	12,339	205	20.011	451.5	1.395
CO2	37,252	289	28.194	840.6	1.641
CO3	46,658	348	33.645	644.2	1.892
EC1	51,319	437	37.217	816.9	2.786
EC2	52,639	368	32.060	666.3	2.464
