Wing and Pappus Appendages Decrease Seed Terminal Velocity: A Meta‐Analysis

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
This meta‐analysis integrated terminal velocity records for 1479 species from various sources and explored descriptive patterns by taxonomic group, seed dispersal vector, and seed appendage type. This study revealed that wing and pappus appendage decrease seed terminal velocity with a robust analysis using regression models to predict terminal velocity.
