Forest structure and connectivity drive the functional recovery of seed rain

Journal of Ecology, Volume 114, Issue 2, February 2026.
Local forest structure and landscape‐scale connectivity shape distinct but complementary pathways of the functional recovery of seed rain in tropical forests. Structural complexity promotes functionally diverse plant–frugivore interactions locally, while connectivity facilitates the arrival of late‐successional seeds from external sources.
