      abstract     = {Carbon isotope analyses of terrigenous organic matter are
                      often used to reconstruct changes in the isotopic
                      composition of upper ocean and atmospheric carbon
                      reservoirs. Carbon isotope values from tree-rings, fossil
                      wood, and coal matrices have been related to climatic change
                      (e.g. temperature, humidity) via water-use efficiency of
                      land plants. In this study, we report on carbon isotope
                      analyses on low-rank coal deposits of the Alpine Realm and
                      Middle German Lignite District covering the Early Eocene to
                      Pliocene time interval. Fossil wood and extracted wood
                      cellulose from gymnosperms and angiosperms, respectively,
                      are used for paleoenvironmental reconstructions. The trend
                      in delta C-13 is parallel to the carbon isotope record
                      obtained from benthic foraminifera, because both data sets
                      sample a common reservoir in the atmosphere. The evaluation
                      of the magnitudes of delta C-13 variations of coal caused by
                      environmental change, requires the correction of the delta
                      C-13 data due to the effects of different contents of lipids
                      in the organic matter, differences in biogeochemical carbon
                      cycling, varying contributions of gymnosperms versus
                      angiosperms to peat formation, and differences in delta C-13
                      of atmospheric CO2. The resulting carbon isotope record of
                      coal generally co-vaFies with the estimated variability in
                      mean annual temperatures during the Tertiary, based on
                      paleobotanical data. Changes in humidity and pCO(2) may be
                      responsible for deviations between the isotopic trend and
                      the paleotemperature curve during the Miocene. The obtained
                      temperature coefficient for delta C-13 of C3 plants of about
                      $0.3\%./degrees$ C is in agreement with the results of
                      previous studies. (C) 2008 Elsevier B.V. All rights
