Soluble carbohydrate (open bars) and starch (solid bars) content in F. sylvatica, S. aucuparia, L. decidua and P. abies at four sites (described in Table 1) in winter and in summer. Hatched bars show Tyrolean sites; open bars, Auvergne sites. Different letters indicate significant differences (P < 0.05) between different sites per species, respectively. Stars indicate significant differences between winter and summer. For F. sylvatica and S. aucuparia, only one replicate was available
