Abstract

Seasonal variation in δ13 C and δ18 O of cellulose (δ13 C c and δ18 O c) was measured within two annual rings of Pinus radiata growing at three sites in New Zealand. In general, both δ13 C c and δ18 O c increased to a peak over summer. The three sites differed markedly in annual water balance, and these differences were reflected in δ13 C c and δ18 O c. Average δ13 C c and δ18 O c from each site were positively related, so that the driest site had the most enriched cellulose. δ13 C c and δ18 O c were also related within each site, although both the slope and the closeness of fit of the relationship varied between sites. Supporting the theory, the site with the lowest average relative humidity also had the greatest change in δ18 O c‰ change in δ13 C c. Specific climatic events, such as drought or high rainfall, were recorded as a peak or a trough in enrichment, respectively. These results suggest that seasonal and between‐site variation in δ13 C c and δ18 O c are driven by the interaction between variation in climatic conditions and soil water availability, and plant response to this variation.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
