Results of canonical correspondence analysis of species distributions.

Results based on the density of trees per m2 for each species with dbh >1 cm in the 2005 census still alive in 2008 are shown for (a) all stems (>1 cm dbh) (b) juveniles (1–10 cm dbh) (c) adults (>10 cm dbh). Results based on the total basal area per species per site are shown for (d) all stems (e) juveniles and (f) adults. The four soil types (wet alluvium (WA), dry alluvium (DA), shale (SH) and latterite (LA)) and location (on or off mounds) were used as nominal environmental variables. Surface areas of the ground and the mound were used as covariables. Lambda is the corresponding eigenvalue and P is the conditional probability level. With a Bonferroni correction for multiple comparisons, p is significant at the level of 0.008 (p = 0.05/6).
