Fig. 2: Fertilization factorial effects.

From: Forb diversity globally is harmed by nutrient enrichment but can be rescued by large mammalian herbivory

Fig. 2

The effect of different nutrients (fertilization factorial experiment) on (A) species richness and (B) cover for forbs (purple) and grasses (green). Model estimates for log response ratios are shown relative to the control treatment (estimate = 0). Response variables were converted to log response variables to account for the change from pretreatment to current data with cover data normalized by maximum plot cover. Multiple nutrient interactions are included for richness. N refers to nitrogen, P refers to phosphorus, and Kμ to potassium with micronutrients. Error bars show the 89% confidence interval.
