dc.description.abstractTo anticipate European climate scenarios for the end of the century, we explored the climate gradient within the REINFFORCE (RÉseau INFrastructure de recherche pour le suivi et l’adaptation des FORêts au Changement climatiquE) arboreta network, established in 38 sites between latitudes 37◦ and 57◦, where 35 tree species are represented. Understanding how climate affects tree phenology, biotic and abiotic vulnerability, is a most important research subject under Climate Change. We focused on determining which climatic variables best explain their survival and growth, and identify which species that are more tolerant to climate variation and those whose growth and survival future climate might constrain. We used empirical models to determine the best climatic predictor variables that explain tree survival and growth, to predict the impact on the specific response of tree species to changing climate scenarios, to evaluate the loss and assess the risk of maintaining or changing species, under each scenario. Considering the scenarios described on IPCC’s Fifth Assessment Report, predictions were run under two main Representative Concentration Pathways (RCP) 4.5 and 8.5. Precipitation-transfer distance was most important for the survival of broadleaved species, whereas growing-season-degree days best explained conifer-tree survival. Growth (annual height increment) was mainly explained by a derived annual dryness index (ADI) for both conifers and broadleaved trees. Species that showed the greatest variation in survival and growth in response to climatic variation included Betula pendula Roth, Pinus elliottii Engelm., and Thuja plicata Donn ex D.Don, and those that were least affected included Quercus shumardii Buckland and Pinus nigra J.F.Arnold. We also demonstrated that provenance differences were significant for Pinus pinea L., Quercus robur L., and Ceratonia siliqua L. A higher survival risk is expected for conifer species, especially for species like Calocedrus decurrens, Pseudotsuga menziesii, and Pinus nigra. For growth, high risk is indicated for Larix decidua, Pinus pinaster, and Betula pendula. Risk distribution points to higher risk at southern sites, and higher production potential for northern sites. Here, we demonstrate the usefulness of infrastructures along a climatic gradient like REINFFORCE to determine major tendencies of tree species responding to climate changespt_PT
