Soil analyses along the stress gradient.
Soil analyses (means ±SE) of the mesocosms having different intensities of stress (low stress: SL, medium stress: SM, and high stress: SH) in 2009 (a) and 2014 (b). Letters indicate significant differences in means. Note that decreasing stress implies increasing soil fertility.
Fig 2.
Maximum aboveground biomass along the stress gradient in 2009.
Peak aboveground biomass (means ±SE) in 2009 for the 24 mesocosms under different intensity of stress (SL: low stress, SM: medium stress, and SH: high stress). Letters indicate significant differences in means.
Fig 3.
CSR ordination of individual species.
Ordination of the 37 species to the CSR triangle using StrateFy. Red dots represent annual (A) species while blue dots represent perennial (P) species. Red and blue squares indicate the average CSR values for annuals and perennials, respectively.
Fig 4.
CSR ordination of community-weighted values.
Community-weighted mean CSR values (CCWM, SCWM and RCWM) of the 24 mesocosms under different intensities of stress (a) and disturbance (b). In (a), dots in red, purple and blue represent mesocosms under low stress (SL), medium stress (SM) and high stress (SH), respectively. Squares in red, purple and blue indicate the average CSR values for SL, SM and SH, respectively. In (b), dots in red, purple, green and blue represent mesocosms under different levels of disturbance: D04, D08, D027 and D54 (4, 8, 27 and 54 out of 80 cells disturbed per mesocosm each year). Squares in red, purple, green and blue indicate the average CSR values for D04, D08, D027 and D54, respectively.
