Leaf, fruit, wood and total above-ground (sum of leaves, wood, fruits) production of main tree genera at different tree species diversity levels (DL) (means ± 1 SE; data from three plots). Different lower-case letters indicate significant differences between the three diversity levels, capital letters indicate significant differences between the years, and greek letters stand for differences between the species within DL 2 or DL 3.

Leaf, fruit and wood production of main tree genera at three tree species diversity levels (DL) normalized to the respective basal area (means of three plots per DL ± 1 SE). Different lower-case letters indicate significant differences between the DLs, capital letters indicate significant differences between the years, and greek letters indicate tree species differences within DL 2 or DL 3.
