The relationship between the seasonal uptake of carbon and its allocation to woody biomass remains poorly understood, leaving a significant gap in our capacity to predict carbon sequestration by forests. Here, we compare the intra-annual dynamics of carbon fluxes and wood formation across the Northern hemisphere, from carbon assimilation and the formation of non-structural carbon compounds to their incorporation in woody tissues. We show temporally coupled seasonal peaks of carbon assimilation (GPP) and wood cell differentiation, while the two processes are substantially decoupled during off-peak periods. Peaks of cambial activity occur substantially earlier compared to GPP, suggesting the buffer role of non-structural carbohydrates between the processes of carbon assimilation and allocation to wood. Our findings suggest that high-resolution seasonal data of ecosystem carbon fluxes, wood formation and the associated physiological processes may reduce uncertainties in carbon source-sink relationships at different spatial scales, from stand to ecosystem levels. info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 15.7 2024 MULTIDISCIPLINARY SCIENCES 10 / 136 = 0.074 2024 Q1 T1 4.761 2024 Biochemistry, Genetics and Molecular Biology (miscellaneous) 2024 Q1 Physics and Astronomy (miscellaneous) 2024 Q1 Chemistry (miscellaneous) 2024 Q1 23.4 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Mencuccini, Maurizio García-Valdés, Raúl Antonucci, Serena Arzac, Alberto Biondi, Franco Buttò, Valentina Camarero, J.
