      abstract     = {The stable isotopes of carbon were analysed in total wood
                      and cellulose from the tree-rings of the tropical wood
                      species Cariniana micrantha (Ducke). The aim was to examine
                      the isotopic relationship between total wood and its
                      cellulose over the last two and a half centuries. Although
                      the correlation for the whole time period is very high (r =
                      0.96) it is remarkable that different sub-periods deviate
                      strongly from this close relationship. Consequently, a good
                      correlation from the subset of a longer isotopic record
                      cannot necessarily prove its validity for the whole record.
                      The study indicates that changes of the carbon isotopes of
                      cellulose and of total wood show sometimes during short
                      sub-periods different isotope patterns presumably caused by
                      different environmental effects. Thorough calculations
                      indicate that strong variations within the isotopic record
                      especially changes of the isotopic level along a chronology
                      lead to high correlations between δ13Cwood and δ13Ccel.
                      Contrary thereto subsections with low isotopic variability
                      lead to low correlations. The results imply that long term
                      trends provide similar patterns. Therefore, if long term
                      trends are of interest such as e.g. in climate
                      reconstruction then total wood can be analysed in favour of
                      cellulose, thus saving a tremendous amount of work. However,
                      if short term aspects from a longer record are of interest,
                      cellulose and total wood may sometimes provide different
                      information. In addition it is hypothesized that during
                      intervals of low isotopic variability the proportions of the
                      various wood components may change relative to each other,
                      leading for certain time intervals to different isotope
                      patterns.},
