Plant Functional Group Composition Modifies the Effects of Precipitation Change on Grassland Ecosystem Function
Figure 5
Effect of precipitation change and functional identity on extractable soil P in different seasons.
The response of soil extractable P to precipitation change (PC) and functional group (FG) identity in each season. a) Spring (presence/absence of FG1, F1,154 = 14.1, p = 0.0003, interaction between PC and FG2, F1,45 = 6.88, p = 0.0096), b) Summer (NS), c) Autumn (NS), d) Winter (interaction between PC and FG2 F1,45 = 5.005, p = 0.0303).
