| Abstract: |
| – |
• Construction cost (g glucose g−1), chemical composition and morphology of leaves of beech (Fagus sylvatica L.) and two co-occurring valuable broadleaved species (sycamore maple — Acer pseudoplatanus L. — and ash — Fraxinus excelsior L.) were investigated along a horizontal light gradient (3–60% of above canopy radiation) and from top to bottom within the
crowns in a fairly even-aged mixed-species thicket established by natural regeneration beneath a patchy shelterwood canopy. |
