Table 2.

Repeated measures ANOVA (linear mixed effect model) results of the main effects of alpine grassland types and three climate factors (temperature, precipitation, and sunshine duration) as well as their interactions, on NPP dynamics, allocations and root turnover rates (RTR) (n = 5, α = 0.05).

^† AGT, MAT, MAP, and H represent alpine grassland types, mean annual temperature, annual precipitation, and sunshine duration, respectively. BNPP10/BNPP is the proportion of how much of the BNPP is in the top 10 cm of the soil. ^‡ Correlation is significant at * P < 0.05, ** P < 0.01, and *** P < 0.001 levels (two-tailed test). MS represents mean squares.
