  1. Note: fixed effects (log-transformed tree species richness, year, and the year-dependency of tree species richness) were fitted sequentially (type-I sum of squares) as indicated in the table. The data set for site A includes 3 years (2014–2016), whereas the data set for site B includes 2 years (2015–2016). Year was fitted as continuous variable. df and ddf stand for numerator and denominator degree of freedom; logSR for log2(tree species richness) and F and P for F-ratio and P-value of the significance tests
