Long-Term Cambial Phenology Reveals Diverging Growth Responses of Two Tree Species in a Mixed Forest Under Climate Change.

ABSTRACT: The net effect of stress induced by climate change on forest functional dynamics remains uncertain. We monitored the dynamics of wood formation and cambial phenology for 11 consecutive years in two co-occurring tree species with different drought tolerance, Pinus sylvestris and Quercus pyrenaica, providing a unique long-term xylogenesis dataset (2012-2022). To assess the influence of climate on cambial and xylem developmental phases, we analyzed biologically meaningful climatic covariates across different time windows. In pine, late-winter temperatures strongly regulated the onset of cambial reactivation, advancing it 5.5 days per°C of warming, with reactivation occurring between early April and mid-May depending on winter thermal conditions. The onset of cambial reactivation in oaks was i
