Figure 4: Model of the impacts of climate, fire and atmospheric CO2 on the vegetation of tropical Africa.
From: CO2 and fire influence tropical ecosystem stability in response to climate change
Left: cartoon of changes in the climate-ecosystem balance as a function of time. Right: schematic of changes in each parameter indicating the size and direction of change between timesteps (arrows) and the relationships between the parameters (red: negative feedback, blue: positive feedback, circle: hypothesized driver of the relationship, dashed: the relationship between these two parameters is weakened by other feedback relationships.
