Fire tolerance traits did explain a significant component of the variance in observed shifts in the abundance of tree species. However, traits related to the carbon economy of photosynthesis were also important. The relationship (solid line) between the stem diameter of a 2-m-tall tree (estimated from the allometric models in Fig. 1) and the probability of topkill of a 2-m-tall tree in a dry season fire of 2000 kW m−1 fire for common savanna tree species (this latter variables are the mean estimates from Fig. 3). The labels indicate the species names (see Table S1).
