Determinants of tree species distributions: comparing the roles of dispersal, seed size and soil specialization in a Bornean rainforest.

In this study, the ecological and evolutionary patterns of covariation among dispersal mode, seed size and soil specialization at Lambir Hills National Park, Sarawak, Malaysia, were studied. Results showed that seed size, dispersal mode and small-scale clumping intensity were highly conserved phylogenetically. The random distribution of soil specialization on the phylogeny was illustrated by the fact that 73% of the families and 48% of the genera with >1 species that were analysed for soil specialization contained at least one specialist and one generalist. Soil specialists and generalists had similar overall frequencies of species in each of the four dispersal modes. Evolutionary transitions between modes of dispersal and soil specialization categories were relatively independent. Species with the same dispersal mode had similar seed sizes across the different soil specialization categories. When ranked by increasing mean seed length, ballistic-dispersed species had the smallest seeds, followed by animal-, wind- and gravity-dispersed seeds. Variation in small-scale dispersion due to dispersal mode was significant. The most intensely clumped species were among specialists of the clay soil, whereas the least-clumped species were specialists of the two poorer soils, sandy loam and loam soils, and generalists. Slopes of the relationship between small-scale clumping intensity and seed length were significantly different from zero for all dispersal modes.
