DescriptionThe flow of organic matter and nutrients from catchments into the streams draining them and the biogeochemical transformations of organic matter and nutrients along flow paths are fundamental processes instreams (Hynes,1975; Fisher, Sponseller & Heffernan, 2004). Microbial biofilms are often the primary interface for organic matter and nutrient uptake and processing in streams, and several studies have demonstrated the extent and significance of nutrient limitations on stream ecosystem functions (Davis & Minshall, 1999; Wold & Hershey, 1999; Tank & Dodds, 2003; Hoellein et al., 2007).
