| Zusammenfassung |
| We present the first chronologies (AD 1907-2006) of stable oxygen (δ18O), hydrogen (δ2H)
and carbon (δ13C) isotope composition of Larix decidua tree-rings, growing at the forest limit
in the SE corner of the European Alps. Climate in June appears to have the strongest control
on tree ring width (TRW), while later summer conditions (July-August) influence the stable
isotope composition. All four proxies are strongly correlated with temperature and also
sunshine hours, but precipitation has less impact. Our results suggest that trees growing at
this site have an adequate water supply and that their growth is limited mainly by temperature
and sunshine hours. A combination of TRW and δ13C provides the greatest potential for
reconstructing past temperatures (June to August) with significant (p |
