Relative importance of stand factors vs. diversity
The optimal model obtained by model selection based on all (sub)plots showed that (Table 3), for stand biomass and productivity, DBHmax was the most powerful predictor at each grain size (as indicated by the chi-square or F values). Meanwhile, diversity indices entered the models only occasionally and revealed weak effect. For ecosystem stability, however, diversity indices play a dominant role at all grain sizes, while stand factors were excluded from all models.
