Appendix
Appendix 1. Number of resident and foreign individuals on each topographic habitat in the
Korup 50-ha plot, Cameroon. Resident individuals are those of species specializing on the
habitat, whereas foreign individuals are those of species that specialize on one of the other
habitats. Generalists belong to species with no specialization. Rare species, those with <50
individuals, were not assigned specializations due to low sample size (Chuyong et al. 2011). The
percentage of individuals in each habitat that are resident is also given. The first row gives the
area out of 50 ha occupied by each habitat.

Appendix 3. Median growth (mm · y−1) and mortality (%. y−1) of Cameroonian tree species that
are habitat generalists or specialists on different topographic habitats types (habitat preference),
as defined in the main text. Rates with 95% confidence intervals (CI) are given for all trees (all),
saplings (10–50 mm diameter at breast height; dbh), and adults (≥200 mm dbh), with the number
of species (No. species) in that preference group and DBH class. All rates are the means of
species medians, weighted by species, so a species with 50 individuals contributes just as much
as a species with 5000 individuals.
