This scientific commentary discusses the importance of understanding carbon source-sink dynamics in masting tree species, particularly in the context of climate change and drought stress. The authors examine the responses of carbon allocation to environmental constraints in stone pine stands, focusing on reproductive effort, radial growth, and tree-ring isotope composition. They find evidence of a shift from sink-limited to source- and sink-co-limited reproduction, suggesting diminishing carbon resources due to drought stress. However, caution is needed in interpreting the data, and further research is necessary to fully understand carbon allocation in trees. [Extracted from the article]
