Synthesis

We will combine both empirical and modeling approaches to quantify how species and above- and belowground C stocks/fluxes respond to single/multiple burns and climate change.

How does fire frequency affect successional trajectories and aboveground C stocks? Which mechanisms are responsible for the trends in post-fire regeneration and C cycling? 

How does fire frequency affect coarse woody debris and soil C stocks? How does it affect pyrogenic C and soil carbon efflux,  and depth to the top of the permafrost? 

How does climate change alter the effects of fire frequency on successional trajectories, above- and belowground C stocks and C sink strength? Which mechanisms are responsible for the trends in post-fire regeneration and C sink strength under climate change and do they vary spatially?
