      abstract     = {The temperature response of heterotrophic soil respiration
                      is crucial for a reliable prediction of carbon dynamics in
                      response to climatic changes. Most multi-pool models
                      describe the temperature dependence of carbon decomposition
                      by a response function which uniformly scales the
                      decomposition constants of all carbon pools. However, it is
                      not clear whether the temperature response does, indeed,
                      conform to such a simple formulation. In this study, we
                      analysed measured CO2 efflux from wheat decomposition
                      experiments under six different temperatures (5, 9, 15, 25,
                      35 and 45 degrees C). Data were interpreted by assuming that
                      litter could be sub-divided into two pools, a labile and a
                      more recalcitrant one, that would each decay exponentially.
                      We found that the observed patterns of carbon loss were
                      poorly described if we used the same relative temperature
                      response functions for the decomposition of both pools and
                      assumed the same chemical recalcitrance (expressed as the
                      ratio of labile and recalcitrant pool sizes) at all
                      temperatures. Data prediction could be significantly
                      improved by using different temperature response functions
                      for the decomposition of the two different organic matter
                      fractions. Even better data prediction could be achieved by
                      assuming that chemical recalcitrance varied with
                      temperature. The data could also be well described by the
                      more sophisticated carbon-dynamic models RothC and
                      CenW/CENTURY, again, provided that the ratio of litter
                      fractions in the initial input material was modified with
                      temperature. Our findings thus suggest that the temperature
                      dependence of organic matter decomposition cannot be fully
                      described with the simple approaches usually employed but
                      that there is a more complicated interplay between the
                      temperature dependence of decomposition rates and
                      temperature effects on the chemical recalcitrance of
                      different organic matter fractions. (c) 2008 Elsevier Ltd.
