Fig. 7: Fire impacts on nitrogen cycling microbes.
From: Microbial contribution to post-fire tundra ecosystem recovery over the 21st century
Changes relative to the baseline RCP8.5-no_fire scenario in the biomass (gC m−2) of nitrogen cycling organisms, NH4+ and NO2− oxidizers, facultative denitrifying bacteria, and diazotrophic bacteria under different fire scenarios for the period spanning 2000–2100. Panels show the same depth range (0–0.45 m) and temporal scale (2000–2100) for the mild fire severity (left side), and the severe fire (right side panels). Panels depict a biomass of four microbial functional groups over the century for a fire ignited in 2007, b microbial biomass over the RCP8.5 simulations until the onset of fire in 2080. Red arrows along the x-axis indicate the year fire was initiated. The biomass of each organism represents the difference between the total microbial biomass over time.
