Few long-term effects of simulated climate change on volatile organic compound emissions and leaf chemistry of three subarctic dwarf shrubs

▶ Long-term warming altered near-infrared reflectance spectra of the leaves. ▶ NPK fertilization increased foliar P and, for Betula nana, N concentration. ▶ Warming, fertilization and shading had few effects on BVOC emissions per unit leaf mass. ▶ On square meter basis, warming increased total BVOC emission from B. nana.
