From Seed to Seedling: Constraints Imposed by Warming, UV‐B, and Burial Depth on Alpine Cushion Plant Recruitment

Ecology and Evolution, Volume 16, Issue 1, January 2026.
This study investigated the effects of warming temperatures, intense UV‐B radiation, and seed burial depth on seedling emergence, growth, and survival of 11 cushion plant species in alpine subnival zones of the Himalaya‐Hengduan Mountains. Deep burial (> 1 cm) severely inhibited emergence in 10 species, with viability loss within 3 months.
