  abstract = {{G}eomorphic landscape features have been suggested as indicators of forest diversity. {H}owever, their explanatory power has not yet been explicitly tested at a regional scale in tropical rainforest. {W}e used forest inventories conducted according to a stratified sampling design (3,132 plots in 111 transects at 33 sites) and holistic multi-scale geomorphological mapping derived from a {S}huttle {R}adar {T}opography {M}ission digital elevation model to describe and explain spatial patterns in floristic composition across {F}rench {G}uiana (80,000 km(2)). {W}e measured and identified 123,906 trees with {DBH} a parts per thousand yen20 cm and used constrained and unconstrained ordinations to analyze variations in the abundance of 221 taxa and 51 families. {V}ariance partitioning and variograms were used to detect spatial patterns in species composition, compare the explanatory power of spatial and environmental factors, and select the variables that best explain forest composition. {S}trong floristic patterns corresponded to a major latitudinal gradient and significant sub-regional floristic structure. {G}eomorphological landscapes shaped by historic climate fluctuations and major geological events successfully captured these patterns and explained the variation in abundance of 80 taxa, corresponding to 65 % of the inventoried trees. {O}ur findings suggest that long-term forest dynamics are under substantial "geomorphographic control". {A} geomorphological perspective on landscapes that incorporates current and past environmental filters and historical biogeographical processes could thus be used more systematically in tropical regions for regional planning and forest conservation.},
