Beyond species means – the intraspecific contribution to global wood density variation

New Phytologist, Volume 249, Issue 6, Page 2630-2651, March 2026.
Summary Wood density is central for estimating vegetation carbon storage and a plant functional trait of great ecological and evolutionary importance. However, the global extent of wood density variation is unclear, especially at the intraspecific level. We assembled the most comprehensive wood density collection to date, including 109 626 records from
