      abstract     = {Tree-ring widths and stable carbon and oxygen isotopes of
                      five European larch trees from Lotschental, Switzerland were
                      investigated for the period 1900-2004. The objective was to
                      test the suitability of each of these parameters for
                      high-frequency climate reconstructions. This is of special
                      interest with regard to the problem of cyclic larch budmoth
                      (LBM) infestations of alpine larch trees. The results
                      clearly demonstrate that tree-ring width chronologies are
                      not suitable for high-frequency reconstructions because
                      infestations lead to variably reduced tree-ring increments,
                      largely suppressing climate signals. On the other hand, the
                      stable isotope chronologies proved less affected by larch
                      budmoth outbreaks, independent of the strength of the
                      infestations. The correlation of the carbon isotopes with
                      summer temperatures was especially high (r = 0.73) and with
                      precipitation lower but nevertheless significant (r =
                      -0.43). Oxygen isotopes were also correlated with summer
                      temperature (r = 0.46); however, a certain perturbation of
                      normal oxygen isotope signatures due to LBM outbreaks was
                      evident. Contrary to tree-ring widths, none of the LBM
                      outbreaks caused a significant disturbance of the current
                      year's isotopic climate signal and, most importantly, there
                      were no delayed effects in the following years. Thus, stable
                      carbon isotopes in tree-ring chronologies of the European
                      larch provide an excellent opportunity for high-frequency
                      temperature reconstructions.},
