Figure 2: Partitioning of the variation of species density and biomass using landscape structure variables
(Land), stand age (Age) and PCNM variables (space) for different groups of plants
Table 2: Regression standardized coefficients of predictor variables (age and landscape structure) that
explain significant components of spatial patterns of biomass and species density at different scales
