The approximate coordinates of each population are given in decimal degrees. The degree or urbanization of the surroundings of each population was assessed using ISI₅₀₀, the impervious surface index within a radius of 500 m. For each of the sampled populations, the bacterial and yeast species richness (number of OTUs) and incidence (frequency of occurrence) are presented
