Abstract Increased wildfire activity warrants more research into fire-driven biotic changes in soil, including soil viral communities, given the roles of microbes organic matter decomposition, nutrient cycling, and post-fire recovery. Leveraging size-fraction metagenomes (viromes), here we studied community responses to woodland chaparral soils at five timepoints over 1 year following California LNU Complex wildfire. We also compared samples unburned controls final three leveraged published viromes from same sites nine months before fire as pre-burn controls. Viral composition differed significantly burned both habitats, did chemistry prokaryotic communities (16S rRNA gene amplicons). Viromic DNA yields (a proxy for particle abundances) indicated initial biomass reductions due fire, but a return baseline abundances (indistinguishable controls) within months. Fire-associated habitat filtering was further by comparison PIGEON “species” (viral operational taxonomic unit (vOTU)) reference database, with vOTUs conifer forest representing 19%–31% detected habitats only 0.6%–6% Together, these results indicate significant wildfire, attributable least part concomitant their host physicochemistry.
