      abstract     = {Stable organic carbon and nitrogen isotopes can be used to
                      interpret past vegetation patterns and ecosystem qualities.
                      Here we present these proxies for two loess‐palaeosol
                      sequences from the southern Carpathian Basin to reconstruct
                      the palaeoenvironment during the past 350 ka and establish
                      regional commonalities and differences. Before now, isotopic
                      studies on loess sequences from this region were only
                      conducted on deposits from the last glacial cycle. We
                      conducted methodological tests involving the complete
                      decalcification of the samples prior to stable isotope
                      analyses. Two decalcification methods (fumigation method and
                      wet chemical acidification), different treatment times, and
                      the reproducibility of carbon isotope analyses were tested.
                      Obtained results indicate that the choice of the
                      decalcification method is important for organic carbon
                      stable isotope analyses of loess‐palaeosol sequences
                      because ratios vary by more than 10‰ between the wet
                      chemical and fumigation methods, due to incomplete carbonate
                      removal by the latter. Therefore, we suggest avoiding the
                      fumigation method for studies on loess‐palaeosol
                      sequences. In addition, our data show that samples with TOC
                      content $<0.2\%$ bear increased potential for
                      misinterpretation of their carbon isotope ratios. For our
                      sites, C3‐vegetation is predominant and no
                      palaeoenvironmental shifts leading to a change of the
                      dominant photosynthesis pathway can be detected during the
                      Middle to Late Pleistocene. Furthermore, the importance of
                      further stable nitrogen isotope studies is highlighted,
                      since this proxy seems to reflect past precipitation
                      patterns and reveals favourable conditions in the southern
                      Carpathian Basin, especially during interstadials.},
