Aim Tree crowns determine light interception, carbon and water exchange. Thus, understanding the factors causing tree crown allometry to vary at the tree and stand level matters greatly for the development of future vegetation modelling and for the calibration of remote sensing products. Nevertheless, we know little about large‐scale variation and determinants in tropical tree crown allometry. In this study, we explored the co...

We examine the influence of climate, soil properties and vegetation characteristics on soil organic carbon ( SOC ) along a transect of W est A frican ecosystems sampled across a precipitation gradient on contrasting soil types stretching from G hana (15° N ) to M ali (7° N ). Our findings derive from a total of 1108 soil cores sampled over 14 permanent plots. The observed pattern in SOC stocks reflects the very different clima...
