dc.description.abstract
Volcanic eruptions are catastrophic events that allow testing different impacts on the ecosystems.Inputs of volcanic sediments into stream water may lead to drastic changes in the biota; however,the effects on biofilm functional traits remain poorly understood. This field study aimed toevaluate differences in structural and functional traits in the biofilm of streams differentiallyaffected by the eruption of the Puyehue-Cordón Caulle Volcanic Complex (PCCVC, Chile,2011). We examined differences in the structure (chlorophyll concentration, bacterial abundance,and biofilm organic matter and phosphorus content) and metabolic capacities (by use of BiologEcoPlate?) in rock and sand biofilms from six streams with different distances from thevolcanic source. Biofilms from streams near the volcano had higher phosphorus content andbacterial abundance. The Biolog EcoPlate? indicated that there were differences in the use ofsome particular organic molecules among streams. On one hand, the use of substrate by biofilmsfrom rocks and sand differed only in the non-affected streams. On the other hand, the biofilms ofstreams nearest the volcano were characterized by the use of galacturonic acid and this higherconsumption can be related to the dominance of cyanobacteria. Our results suggest that volcanicsediment inputs, still occurring three years after the eruption, change biofilm communities,leading to physiological differences among streams.
