要旨本文	Future precipitation changes are expected to affect plant growth and trait adaptive adjustments. Here, we planted seedlings of 7 tree species in a landslide area of a temperate forest in northern Hokkaido and simulated two years of extreme precipitation treatment. We tested the individual-based trait approach and evaluated the effects of extreme precipitation treatment on intraspecific variation in trait values and how traits predict individual growth performance. We found that extreme precipitation treatment increased intraspecific variation in traits related to drought tolerance but made traits related to landslide protection more conservative. Moreover, extreme precipitation treatment weakened the predictive ability of traits on individual relative growth rates but enhanced the correlation among traits. These results provide valuable information for predicting plant performance responses to future climate change.
