AB Species complementarity by morphological and physiological trait differences could cause distinct temporal andspatial use of resources. Accordingly, mixed stands may enhance production, biodiversity and/or provide a betteradaptation to future climate conditions. We aim to identify species differences in intra-annual stem radialvariation patterns, and to recognize species-specific responses to contrasting weather conditions at key intraannualgrowth phases. Stem radial variation was recorded from high temporal resolution point dendrometers(2012–2014) installed on twelve dominant maritime pine and Pyrenean oak trees in two mixed stands in centralSpain. Species differences in stem radial variation were analyzed by synchrony statistics, intra-annual patternmodelling, and evaluating the dependence of main intra-annual growth phases on climate conditions. Bothspecies showed important differences on intra-annual radial increment pattern despite general stem radialvariation synchrony. Radial increment onset was earlier for maritime pine during the spring and rainy autumns.Species-specific responses to weather indicate that stem radial variation increased with autumn temperature inmaritime pine, but decreased in Pyrenean oak trees. However, summer vapor pressure deficit may reduce stemradial variation for maritime pine. Therefore, maritime pine would adapt more efficiently to warmer temperaturesassociated with climate change, although summer water stress may reduce this competitive bonus.
