Hoeinghaus et al. 2007 • Which river concept explains energy sources in 10 tribs of Parana’ river? • Low-gradient, high gradient, reservoirs • C,N isotopes for fishes, molluscs, plants, detritus • Big conclusions? • Lowland river foodwebs = C from aquatic macrophytes • Reservoirs = C from algae more important • High gradient rivers = C from filamentous algae • Relate to river concept?
