ResumenDiverse forests are crucial for the carbon cycle and forest productivity, but increased tree mortality and decreased growth could be aggravated by the negative effects of drought and high temperatures. Despite its importance for understanding and predicting climate change effects in forest ecosystems, it is not well understood how diversity loss may alter growth and mortality responses to elevated climatic stress. We used data from c. 55,000 plots across Europe and maximum likelihood techniques to quantify the effect of stand structure, climate and diversity on stand growth and mortality, and to explore whether functional diversity can modulate demographic responses to climate and competition. Diversity had a strong effect on stand growth and mortality in Mediterranean forests. Furthermore, functional diversity had indirect effects through modification of growth and mortality response to evapotranspiration in broad-leaved deciduous forests and to tree density in Mediterranean forests. We suggest that the positive effects of functional diversity may have been underestimated because high functional diversity may also ameliorate stressful conditions in different forests
