Elevated CO2 along with rising temperature and water deficits can lead to changes in tree physiol.and leaf biochem. These changes can increase heat- and drought-induced tree mortality. We aim to reveal the impacts of climatic drivers on individual compoundsat the leaf level among European larch (Larix decidua) and mountain pine (Pinus mugo) trees, which are widely distributed at high elevations. We investigated seasonal carbon isotope composition(δ13C) and concentration patterns of carbohydrates and organic acids in needles of these two different species from a case study in the Swiss National Park (SNP). We found that averageand min.air temperatures were the main climatic drivers of seasonal variation of δ13C in sucrose and glucose as well as in concentrationsof carbohydrates and citric acid/citrate in needles of both tree species. The impact of seasonal climatic drivers on larch and mountain pine trees at the needle level is in line with our earlier study in this region for long-term changes at the tree-ring level. We conclude that the species-specific changes in δ13C and concentrationsof carbohydrates and organic acids are sensitive indicators of changes in the metabolic pathways occurring as a result of climatic changes.
