The analysis of plant elemental composition and the underlying factors affecting its variation are a current hot topic in ecology. Ecological adaptation to atypical soils may shift composition. However, no previous studies have evaluated relevance against other such as phylogeny, climate or individual soil conditions. We effect environment (climate, soil), affinity gypsum on 83 taxa typical Iberian ecosystems. used new statistical procedure (multiple phylogenetic variance decomposition, MPVD) decompose total explained by different across all nodes tree target species (covering 120 million years Angiosperm evolution). Our results highlight phylogeny plants both at early (with development key preadaptive traits) recent divergence times (diversification flora concurrent with deposit accumulation). Despite predominant effect, had strong impact plants, particularly sulphur concentrations, while effects were smaller. Accordingly, we detected convergent evolution specialists from lineages increased magnesium foliar concentrations.
