Tropical Seed Trait Database: advancing seed functional ecology in the world's most biodiverse region

Plant functional traits connect biodiversity to ecosystem processes, serving as key metrics for assessing how biota responds to environmental conditions. Functional seed traits are critical because they underpin recruitment and colonization, shaping biodiversity patterns and influencing ecosystem resilience. Yet, seed traits remain underrepresented in major data repositories, with severe gaps in the tropics. Climatic, geological, and historical differences between tropical and temperate regions drive distinct regeneration dynamics, suggesting that the paucity of tropical seed trait data limits our ability to predict regeneration niches and weakens global models largely based on temperate ecosystems. To address this gap, we introduce the Tropical Seed Trait Database (TSTD), an open‐access repository spanning the full ecological spectrum of tropical seeds. The TSTD is conceived as a community‐driven repository of primary data contributed directly by data owners, rather than as a secondary aggregation of global databases. It was built through contributions from ecologists working across all tropical regions, reached through direct contact, and its first version compiles 78 datasets, totaling 137 583 records across 44 functional traits. Covering 5115 species in 33 countries, with the Neotropics overrepresented, the TSTD marks a crucial step toward more inclusive, globally representative trait databases that can open multiple research avenues.
