This study shows that low burn intensity increases N2O emissions through denitrification, while high burn intensity reduces emissions due to microbial loss and resource limitation.

This study investigates how wildfires affect ammonia-oxidizing bacteria (AOB) and archaea (AOA) abundance and denitrifier activity, leading to increased soil emissions of nitric oxide (NO) and nitrous oxide (N2O) in California chaparral.

This study identifies genomic strategies and trait trade-offs in pyrophilous fungi that enable survival and nutrient cycling post-fire, revealing gene duplication, horizontal gene transfer, and sexual recombination as key evolutionary mechanisms.

This study evaluates optimal soil storage and media methods for isolating pyrophilous bacteria and fungi from burned soil, finding that -80°C storage without glycerol preserves species diversity and that PyOM-based media enhances culturing of fastidious microbes.
