a–e Line chart (Average ± SD, n = 4 under each treatment in each year) for NEE, ER, ET, CUE, and WUE under ambient and warming conditions with the results of t-test and two-way ANOVA (W: warming; Y: year; W × Y: interactions of warming and year). f, g Bar plots (Average + SD, n = 4 for each bar) with the result of t-test for the changes in soil NH4+-N and NO3--N contents under ambient and warming conditions. *p < 0.05; **p < 0.01; ***p < 0.001.
