Phylogenetic, geographical, environmental parameters of leaf samples and thermophilic state of OTU identification. 1, average annual sum of solar potential; 2, average temperature corresponding to the month of sampling. 3, abundance of identified OTUs are shown for each leaf sample: T+; correspond to closest species described as thermophilic or thermo-resistant; T?; correspond to closest species described as non-thermophilic but belonging to genus containing some thermophilic or thermo-resistant species; T-; correspond to closest species described as non-thermophilic or thermo-resistant or thermophilic status unknown due to a distant phylogeny or low abundance of the OTU.
