The growing conditions of sampled plants was:
| Location | growingCondition |
|---|---|
| Lambir Hills National Park, Sarawak, Malaysia | field wild |
| Species | Family | Pft |
|---|---|---|
| Scaphium macropodum | Malvaceae | deciduous angiosperm |
| Scaphium longipetiolatum | Malvaceae | deciduous angiosperm |
| Scaphium borneense | Malvaceae | deciduous angiosperm |
Sampling strategy: trees that showed no evidence of past breakage were collected
Leaf area: Leaf area was determined with a scanner (Epson EP Scan GT-8000) combined with an area-determination software (Adobe Photoshop 2.5J.
Stem cross sectional area: It was defined as the geometric mean of the two stem diameters measured.
Height: Measured by a measuring tape.
Crown area: This was calculated as the projection of an ellipse defiend byt eh tow crown diameters.
Biomass: The sample trees were cut into four fractions; leaves
** petioles**: branches adn stems
** that were dried seperately at 80oC for 1 week in an oven and their oven dry mass were measured.**:
Traits: Species with moderately shade tolerance for all
Growth environment: Under the closed canopies in a primary forest.
Year collected: 1996

This is how the study Yamada2000 fits in the entire dataset (grey). each colour represents a species. A legend of species names with colours is included at the end for reports with 1 < n < 20 species.
