    • Island size class did not significantly affect concentrations in harvested epiphytes of foliar N [F(2,S2) = 0.37, P = 0.691] or P [F(2,S2) = 1.83, P = 0.170], but did affect concentrations of root N [F(2,47) = 4.36, P = 0.018] and root P [F(2,47) = 5.65, P = 0.006]. The mean root P concentration was 17% greater in the small than in the large islands, whereas root N was 7% greater in the large than in the small islands.

    • For the observational study, humus gravimetric moisture concentration at harvest was significantly related to island size [F(2,51) = 4.59, P = 0.015], but not tree species [F(2,51) = 0.36, P = 0.694]. The mean moisture concentration was 28% greater in the large than in the small islands. For the experimental study, moisture concentration did not show a significant relationship with either island size [F(2,40) = 2.33, P = 0.110] or tree species [F(2,40) = 1.16, P = 0.324]. Greater reduction of variation of soil moisture concentration across island size classes was possible for the experimental than for the observational study, because experimental islands were constructed to be the same depth regardless of diameter, so that regardless of island size the interior of each island was 35 mm from the surface.
