The relationship between sapling density quotients and mean dry seed mass for 14 highly shade‐tolerant tree species of warm temperate rain forest (WTRF) on Yakushima in southern Japan. (A) Density in tree‐fall gaps/density in closed stands and (B) density on rocky roadside cuttings/density in closed stands; tree‐fall gaps (totalling 650 m²) and closed stands (2000 m²) in Segire River Basin, and roadside cuttings (90 m²) on same rock type in Ohko River Basin. The species ordered by increasing seed mass are Rhododendron tashiroi, Eurya japonica, Cleyera japonica, Symplocos prunifolia, Distylium racemosum, Myrsine neriifolia, Symplocos tanakae, Illicium religiosum, Symplocos glauca, Neolitsea aciculata, Camellia japonica, C. sasanqua, Nageia nagi and Litsea acuminata.
