Fig. 4: Model perturbation response for varied fire suppression ratios.

From: The rise of angiosperms strengthened fire feedbacks and improved the regulation of atmospheric oxygen

Fig. 4

Suppression ratio is the assumed increase in global terrestrial NPP under the complete absence of fires, indicative of overall biosphere flammability. a Model is forced by increasing the delivery rate of nutrient phosphate by 50% for a 50 Myr period. b Relative terrestrial biomass. c Modelled atmospheric oxygen mixing ratio.
