  1. Exam topics

  2. 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?

  3. Lytle and Poff 2004 Adaptations to survive floods and droughts ID adaptations Modes: know examples Timing of flow = life history adaptations Predictability = behavioral adaptations Magnitude/freq = morphological adaptations Human impacts

  4. Stone et al. 2005 Macroinvertebrates of ag streams What variables impact them? Methods? Sites? Sampling? What attributes were compared? Which attributes varied with physical variables? What impacts caused low scores for macroinvertebrates?
