20.500.12556/DiRROS-21466 Partial asynchrony of coniferous forest carbon sources and sinks at the intra-annual time scale As major terrestrial carbon sinks, forests play an important role in mitigating climate change. 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. carbon sinks forests conifers intra-annual resolution ponori ogljika gozdovi iglavci znotraj letna ločljivost true false true Angleški jezik Slovenski jezik Neznano 2025-02-10 11:57:28 2025-02-10 11:57:28 2025-02-11 03:36:32 0000-00-00 00:00:00 2024 0 0 Nasl. z nasl. zaslona; Opis vira z dne 9. 8. 2024; str. 1-12 iss. 6169 Vol. 15 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2024-01-01 57 2041-1723 10.1038/s41467-024-49494-5 203984899 https://www.nature.com/articles/s41467-024-49494-5 1 d372a61c-e79d-11ef-9f1e-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=30639 RAZ_Silvestro_Roberto_2024.pdf RAZ_Silvestro_Roberto_2024.pdf 1 B8D45D6E9CA08093647EB0506BA86995 3a90380f8da252b0a51981ab4bd04c1d0752faeddbc38192e3626a4e1329b195 dc579f62-e79d-11ef-9f1e-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=30640 Gozdarski inštitut Slovenije 0 0 0
