Abstract

In dendrochronology the use of stable-carbon isotopes is established as a complementary tool to reconstruct paleoclimate. In this context studies on stable-carbon isotopes and tree ring width of trees from tropical montane zones are still understudied. Therefore, our study examined annual stable-carbon isotopic pattern, ring width and climate conditions in a neotropical forest. As trees are living organisms they respond to environmental changes, which are revealed in the isotopic composition of the α-cellulose. Our first results from broadleaved deciduous trees (Cedrela montana) demonstrate the potential of δ13C values for climate reconstructions. We detected relations between climate, e.g. relative humidity, site conditions and tree growth. Tropical broadleaved deciduous tree species are able to achieve a stable-carbon isotopic signal in their annual rings under everwet conditions and show a good potential for paleoclimatic research. These results could help to identify and interpret extreme climate events (ENSO).
