From: Fire-severity effects on plant–fungal interactions after a novel tundra wildfire disturbance: implications for arctic shrub and tree migration

Fig. 5

Conceptual model of fire-severity effects on vegetation change in the Arctic can be assessed through a factors influencing seedling growth and b the net outcome of substrate and microbial community factors on seedling establishment in non-shrubby tundra. a The thickness of the arrows indicates strength of the causal pathway. Grey text indicates alternative mechanisms influencing seedling biomass after fire, whereas black text indicates the causal pathway investigated and supported in this study. b Substrate effects refer to the positive effect of burn severity on exposure of high-quality, mineral-soil seedbeds
