Intra- and Inter-Annual Growth Patterns of a Mixed Pine-Oak Forest under Mediterranean Climate

Temperature and precipitation variability throughout the year control intra-annual dynamics of tree-ring formation. Physiological adaptation trees to climate change is among key issues better understand predict future forest performance composition. In this study, we investigated species’ coexistence Scots pine pubescent oak growing in a mixed sub-Mediterranean northeast Iberian Peninsula. We assessed cumulative growth patterns derived from band dendrometers during four consecutive seasons long-term changes basal area increment for period 1950–2014. Our results revealed that followed an bimodal pattern. was mainly limited by water availability at intra-annual, interannual decadal time scales, which resulted negative trend. Conversely, displayed unimodal pattern, less climatically constrained. A significant increase denotes overall potential acclimation prevailing climatic conditions expenses higher risk physiological failure extreme events.
