Effects of groundwater inputs on algal assemblages and cellulose decomposition differ based on habitat type in an agricultural stream

Stream communities and processes are known to differ among reaches and habitat types in accordance with environmental variation. However, groundwater input has not been well-explored as a driver of ecological heterogeneity among stream reaches and habitats. We assessed stream biofilm communities (biomass and diatom assemblage composition) and cellulose decomposition in run and riffle habitats across three stream reaches with high, moderate, and …
