Light competition affects how tree growth and survival respond to climate

open access: yesJournal of Ecology, Volume 113, Issue 3, Page 672-688, March 2025.
We analysed the effect of light competition on tree growth and survival along both temperature and aridity gradients for the 33 major European tree species. We used forest data from nine European countries and the SamsaraLight ray tracing model. We found that the effect of light competition is weaker in stressful environments.
