Table 2. Used data and performance of the LME model.
Marginal r2 represents the portion of r2 which can be explained by fixed effects (growth factors) only. Conditional r2 comprises also the random effects (site) part. As Acer pseudoplatanus was only present at one site, the value for conditional r2 is not meaningful and therefore excluded. Due to reasons of consistency, Acer pseudoplatanus’ marginal r2 is calculated analogous as for the other species.
