Short summary
Stream biofilm microbial communities play key roles in elemental cycles and stream food webs, yet little is known about their response to transient changes in dissolved organic carbon (DOC) composition and characteristics. Using chemical analyses and eDNA metabarcoding, this study found that DOC composition shifted during storm events, but the composition of most biofilm communities remained stable, suggesting ecological resilience to transient shifts in DOC composition and characteristics.
