Abstract Background Wildfires have strong impacts on terrestrial and aquatic ecosystems, whose frequency, severity, intensity are increasing with climate change. Moreover, the expansion of exotic monoculture plantations, such as those eucalypts, increases this risk. When wildfires do not cause disappearance riparian vegetation, they still imply fall leaf litter exposed to fire (i.e., crown scorch), which consequences for ecosystems unknown. Experimental design To explore how these inputs may affect stream ecosystem functioning, we conducted a microcosm experiment where quantified decomposition from three tree species (alder, oak, eucalypt) under two conditions (control simulating natural entries subjected 150 °C 3 h mimicking exposure fire). We also examined interaction between factor temperature rise (which is often associated loss vegetation caused by wildfire) manipulating water (10, 12.5, 15 °C). Finally, explored effects variables growth common detritivore, caddisfly Sericostoma pyrenaicum . Results Control alder presented highest rates, were notably reduced due exposure. On contrary, eucalypt was even slower than that oak hardly showed any effect derived The different types determined detritivore growth, greater extent variation related warming, generally had negligible effects. Conclusions Our study shows negative functioning when only involve brief fire. Effects most palatable native species, represents quality input in streams area. results highlight importance protecting forests, especially composed against wildfires.
