Table 2. Association between environmental distance and community turnover.

Community dissimilarity is significantly associated with geographical and soil environmental distance for eukaryote and prokaryote communities in soil and litter. The Multiple Regressions were based on the geographical distance, Euclidean distance matrices of soil properties and community Jaccard dissimilarity indexes. Geographic distances were significant for all communities turnover; however, as geographical closest places are usually more environmental similar, we cannot separate the effect of soil properties from the spatial correlation. All community turnovers were significant with 10,000 permutations (p < 0.001) with the follow R²: prokaryote soil (R² = 0.36 for presence/absence and R² = 0.36 for relative abundance), prokaryote litter (R² = 0.39 for presence/absence and R² = 0.35 for relative abundance), eukaryote soil (R² = 0.21 for presence/absence and R² = 0.20 for relative abundance) and eukaryote litter (R² = 0.32 for presence/absence and R² = 0.30 for relative abundance).
