Extended Data Table 1 The effects of nutrient addition on diversity loss and richness loss increase with time

From: Addition of multiple limiting resources reduces grassland diversity

  1. Linear mixed-effects model of the effects of number of treatment years (ARIMA type-1 autocorrelation) and the number of added resources on diversity (log ESNpie) and richness, with plot nested in block, nested in year, nested in site, as random effects, using all 45 sites. There was a significant, negative interaction between the number of added resources (nres) and year of treatment (year).
