Resumen:
Over the course of their lives, trees may undergo changes in sensitivity to climate during their ontogenetic development, i.e., from seedling to maturity. Identifying these age-dependent responses is relevant to minimize under or over estimations of the climatic signal in dendroclimatic reconstructions. It also provides important clues in predicting the reactions of diferent age-class trees to ongoing climate changes. In this context, the main goal of this study was to determine the sensitivity of radial growth of Austrocedrus chilensis (Ciprés de la Cordillera) to climate variability as a function of tree age. Wood cores from 90 trees growing in the forest-steppe ecotone of northwestern Patagonia in Argentina, were sampled. By analyzing their growth rings, trees were classifed in two age classes: young (
