No Long-Term Decay in α-Cellulose of Living and Relict Trees From the European Alps Over the Past 8,000 years

Popis výsledku v původním jazyce

Tree-ring alpha-cellulose stable isotopes of living trees and dead woods are increasingly used for high-resolution paleoclimate reconstructions spanning centuries to millennia. However, the potential effects of wood decay on alpha-cellulose content (CC) and the composition of tree-ring stable isotopes remain largely unexplored. Here, we present alpha-cellulose content measurements from relict and living trees in the European Alps spanning the past 8,000 years. This study addresses whether preservation context alters the isotopic integrity of alpha-cellulose. We assess the temporal stability of CC, its dependence on tree species, preservation conditions and wood type (subfossil, dry dead, living), as well as its relationship with alpha-cellulose stable carbon, oxygen, and hydrogen isotopes (delta 13C, delta 18O, delta 2H). Our results show that alpha-cellulose remains stable over millennia under alpine conditions. Our results not only confirm the suitability of relict wood for tree-ring stable isotopic analysis and paleoclimate reconstructions, but also provide insights for the improvement of global carbon cycle models.
