River Continuum Concept

  • Headwaters Streams

    • heavily shaded, leaf litter is important

    • shredders / collectors are abundant

  • Mid-order Streams

    • less shaded, algae more important

    • grazers abundant

  • Large Rivers

    • not shaded, phytoplankton present

    • collectors important
