Table 2. Difference (r) and its significance (P) for Bray–Curtis dissimilarity indices between paired soil and wood samples compared to non-paired soil and wood samples.

In the log-level analyses, a soil and wood sample was considered paired if the soil sample was acquired right under the log from which the wood sample was acquired, whereas in other cases the soil and wood samples were considered as non-paired. In the Block-level analyses, a soil and wood sample was considered paired if the soil sample was acquired from the same block (a 25 m × 25 m area) but under a different log from which the wood sample was acquired, whereas wood and soil samples that originated from different block were considered as non-paired. The analyses have been conducted separately for DC 1–5. Statistics were calculated for OTU data, measured either as RA or as presence–absence (PA). Cases with P<0.05 are emphasised with bold font.
