Table S1 The mean soil bulk density of among the depth 10 cm to 100 cm. The soil
bulk densities were averaged from the values of three different positions within the
study site.

Table S2 The contribution of rain water and fog water to soil water at above 10cm
(<10cm) depth and above (< 50cm) inferred with a single isotopic signature (δ18O) in
isoerror1_04 (Phillips, 2001).Volume weighted δ18O of rain water and the volumetric
water content weighted mean isotopic values for soil water were used for the
calculation. The mean values with the range of minimum/maximum proportions (in
parentheses) were also given.

Figure S1
The rainy season foliar water uptake (a) and percent increase in leaf water content (b)
after putting leaves in water for 3 h. The plant species are the evergreen trees (black
bars) Cleistanthus sumatranus, Lasiococca comberi, the deciduous tree species (grey
bars) Mayodendron igneum and Lagerstroemia tomentosa, and the liana species (open
bars) Combretum latifolium, Acacia pennata. The asterisk indicates the foliage absorb
water significantly more than 0 mg H2O cm-2 (a) and significantly increased in leaf
water content (b) (one sample t-test, *, P < 0.05, **, P < 0.01).
