Pooled versus separate measurements of tree-ring stable isotopes.
δ(13)C and δ(18)O of tree rings contain time integrated information about the environmental conditions weighted by seasonal growth dynamics and are well established as sources of palaeoclimatic and ecophysiological data. Annually resolved isotope chronologies are frequently produced by pooling dated growth rings from several trees prior to the isotopic analyses. This procedure has the advantage...
متن کاملStable isotopes in tree rings
Stable isotopes in tree rings could provide palaeoclimate reconstructions with perfect annual resolution and statistically defined confidence limits. Recent advances make the approach viable for non-specialist laboratories. The relevant literature is, however, spread across several disciplines, with common problems approached in different ways. Here we provide the first overview of isotope dend...
متن کاملClimatic and Environmental Reconstruction Based on Stable Isotopes of Parishan Lake (Iran)
The isotopic documents of lake deposition are suitable potential means for studyingthe intercontinental, environmental and climatic conditions. In order to study theenvironmental and climatic conditions of Parishan area in Fars province in Holocene, a Corewas taken with the length of 2m from the Parishan lake sediment. From this core, kernel timeseries was provided from documents of carbon and ...
متن کاملThere is no temperature dependence of net biochemical fractionation of hydrogen and oxygen isotopes in tree-ring cellulose.
The isotopic composition of tree-ring cellulose was obtained over a two-year period from small diameter, riparian zone trees along an elevational transect in Big Cottonwood Canyon, Utah, USA to test for a possible temperature dependence of net biological fractionation during cellulose synthesis. The isotope ratios of stream water varied by only 3.6% and 0.2% in deltaD and delta18O, respectively...
متن کاملUniform climate sensitivity in tree-ring stable isotopes across species and sites in a mid-latitude temperate forest.
Tree-ring stable isotopes, providing insight into drought-induced eco-physiological mechanisms, are frequently used to reconstruct past changes in growing season temperature and precipitation. Their climatic response is, however, still not fully understood, particularly for data originating from non-extreme, mid-latitude environments with differing ecological conditions. Here, we assess the res...
