dc.description.abstractIn Mediterranean forests, increasing tree susceptibility to drought has often been attributed to local site conditions and species-specific adaptations to water scarcity. Climate-growth relationship has been assumed to be stationary; however, warming can induce non-stationary relationships. This study aimed to evaluate whether recent warming has induced non-stationary growth responses in Mediterranean forests. For these two Mediterranean pine species with different life-history traits ( Pinus pinea and Pinus pinaster ), were studied using dendrochronological data, in two areas of Portugal with distinct Mediterranean Type climate (Csb - warm-summer Mediterranean, and Csa - hot-summer Mediterranean). We evaluated average tree ring indices for two periods, before and after the 1970s onset of the warming trend, to determine potential changes in growth sensitivity to moisture availability. Our results reveal that increased warming after the 1970s induced contrasting species-specific responses. Fast growing P. pinaster had enhanced growth during favorable conditions at mesic sites. In contrast, the more xeric P. pinea reduced growth under warming, indicating a change in consideration of these two species capacities to cope with future climatic conditions. We have not found an increase in sensitivity to water availability during warming, therefore, future drought recovery for both species will largely depend on local declines in water availability. These findings highlight the importance of accounting for non-stationary climate–growth relationships when predicting species responses to climate change. Understanding the mechanisms driving tree resilience is critical for developing more accurate and effective forest management strategies under future scenarios of warming and more frequent and severe droughts.en
