Results of partitioning variation between environmental variables and spatial effects for each of the 20 combinations of DBH and cell size using count data.

Note: Adjusted R-squared statistics are shown. Fractions [a] – [d] are as follows: [a] = variation explained by the environmental variables and not spatially structured; [b] = variation explained by the environmental variables and spatially structured; [c] = spatially structured variation not explained by the environmental variables; [d] = residual variation. Fraction [b] is the intersection of the variation explained by linear models of the two groups of explanatory factors. Topographic and edaphic variables were used to compute fractions [a] and [b]. Principal coordinates of neighbor matrix eigenfunctions were used as explanatory variables to compute fractions [b] and [c]. class 0 (DBH ≥1 cm), class 1 (1 cm ≤ DBH
