  abstract = {{A}im {E}xamining tree species-environment association can offer insight into the drivers of vegetation patterns and key information of practical relevance to forest management. {H}ere, we aim to quantify the contribution of climate and soil gradients to variation in {C}entral {A}frican tree species composition (abundance and occurrence). {L}ocation {T}ropical rain forests of southern and eastern {C}ameroon. {M}ethods {W}e established 82 1-ha permanent plots across seven localities and censused all trees >= 10 cm in diameter, representing a total of 37,733 trees and 455 species. {I}n 60 of those plots, we measured 10 soil variables describing texture and nutrients levels and extracted 10 bioclimatic variables from global-gridded climate databases. {W}e synthesized the main environmental gradients by conducting principal component analyses on climate and soil data, respectively. {W}e performed unconstrained and constrained non-symmetric correspondence analyses to account for the individual and joint contributions of climate and soil on species abundance and occurrence. {R}esults {C}limate and soil contributed similarly to variances of species abundance and occurrence (12-15% variance for climate vs 11-12% variance for soil). {C}limate influence mostly concerns some abundant species, while some of the less abundant species were mainly driven by soil. {F}ractions of species variances accounted for by climate and soil show strong correlation when assessed from species occurrence and abundance data. {C}onclusion {V}ariation in occurrence and abundance of tropical forest trees can be partly shaped by both climate and soil gradients in {C}ameroon, which emphasizes the importance to jointly consider soil and climate in species distribution modeling. {L}ess abundant species may express environmental influence differently than abundant species and convey complementary information about community assemblage. {T}hough showing congruent patterns here, species abundance and occurrence reflect different interacting community processes and both should be examined to better understand vegetation patterns.},
