Fig. S1 Spatial distribution of six dipterocarp species on three soil types in a 50 ha plot
in the Pasoh Forest Reserve in 1985. Well drained soil is indicated in black, medium
drained soil in grey and poorly drained soil in white. The aggregated soil type for each
species is given in parenthesis after species name: well drained (WD), medium drained
(MD) and poorly drained (PD)
Fig. S2. Interspecific comparison of annual dbh growth rate (cm year-1) among six
dipterocarp species studied in three aggregate size categories of small (dbh<5 cm, the
left column), medium (5 cm ≤ dbh< 30 cm, the middle column), and large (30 cm ≤
dbh, the right column) in well drained soil (the upmost row), medium drained soil (the
middle row), and poorly drained soil (the bottom row). Bars labeled with different
letters differ significantly among species (Kruskal-Wallis test, P<0.05). *: annual dbh
growth rate were not evaluated since the number of trees was less than 10. Species
abbreviations: (Al) Anisoptera laevis, (Sa) Shorea acuminata, (Sb) Shorea bracteolata,
(Sm) Shorea maxwelliana, (So) Shorea ovalis, (Sl) Shorea leprosula
Fig. S3. Interspecific comparison of annual mortality rate (% year-1) among six
dipterocarp species studied in three aggregate size categories of small (dbh<5 cm, the
left column), medium (5 cm ≤ dbh< 30 cm, the middle column), and large (30 cm ≤
dbh, the right column) in well drained soil (the upmost row), medium drained soil (the
middle row), and poorly drained soil (the bottom row). Bars labeled with different
letters differ significantly among species (Fisher’s exact test for count data with
sequential Bonferroni correction, P<0.05). *: annual mortality rates were not evaluated
since the number of trees was less than 10. Species abbreviation; Species abbreviations:
(Al) Anisoptera laevis, (Sa) Shorea acuminata, (Sb) Shorea bracteolata, (Sm) Shorea
maxwelliana, (So) Shorea ovalis, (Sl) Shorea leprosula
