Mother trees (large hub trees) preferentially allocate carbon to kin seedlings through mycorrhizal networks, even recognizing their own offspring via root exudate signals. When mother trees die (logging), connected seedlings lose vital carbon subsidies — network resilience depends on hub redundancy.
