The table lists the number of clones, observed and estimated species richness, coverage and diversity indices for the clone libraries from dust samples collected in the two buildings during four seasons. Numbers were calculated with DOTUR program. OTUs were defined using a distance level of 3%. S obs, observed number of OTUs; S ACE, estimated number of OTUs using ACE estimator (Hughes et al, 2001); S Chao, estimated number of OTUs using Chao estimator (Hughes et al, 2001); Shannon and Simpson, diversity indices (Hill et al., 2003) 1, Building 1; 2, Building 2; W, winter; Sp, spring; Su, summer; F, fall.
