  abstract = {{T}ree rings provide fruitful information on climate features driving annual forest growth through statistical correlations between annual tree growth and climate features. {I}ndices built upon tree growth limitation by carbon sequestration (source hypothesis) or drought-driven cambial phenology (sink hypothesis) can be used to better identify underlying processes. {W}e used both analytical frameworks on {Q}uercus suber, a sparsely studied species due to tree ring methodological issues, and growing on a favorable sub-humid {M}editerranean climate and deep soil conditions in {T}unisia ({N}orth {A}frica). {S}tatistical analysis revealed the major role of autumnal rainfall before the growing season on annual tree growth over the 1918-2008 time series. {U}sing a water budget model, we were able to explain the critical role of the deep soil water refill during the wet season in affecting both the drought onset controlling growth phenology and the summer drought intensity affecting carbon assimilation. {A}nalysis of recent climate changes in the region additionally illustrated an increase in temperatures enhancing the evaporative demand and advancing growth start, and a decline in rainfalls in autumn, two key variables driving stem growth. {W}e concluded on the benefits of using process-based indices in dendrochronological analysis and identified the main vulnerability of this {M}editerranean forest to autumnal rainfall decline, a peculiar aspect of climate change under summer-dry climates.},
