dc.description.abstract |
The stable carbon isotope ratios (N13C) of whole wood, cellulose and acid-insoluble lignin from annual latewood increments of Quereus robur L., from modern and sub-fossil wood, were measured and their potential use as palaeo environmental indicators examined. The resulting time series demonstrate a very high degree of coherence, with N13C of cellulose isotopically enriched by approximately 3xcompared to N13C of lignin. The N13C values of all three components are influenced by the climate of July and August. Modern whole wood retains the strongest climate signal, perhaps because its composition is closest to that of leaf sugars. In sub-fossil wood there is no evidence that differential decay leads to fractionation of carbon within either cellulose or lignin, but differential decay can alter the cellulose to lignin ratio. |

AB - The stable carbon isotope ratios (N13C) of whole wood, cellulose and acid-insoluble lignin from annual latewood increments of Quereus robur L., from modern and sub-fossil wood, were measured and their potential use as palaeo environmental indicators examined. The resulting time series demonstrate a very high degree of coherence, with N13C of cellulose isotopically enriched by approximately 3xcompared to N13C of lignin.

Modern whole wood retains the strongest climate signal, perhaps because its composition is closest to that of leaf sugars.
