  1. An Ecological Overview of the Potomac River Valley Dann Sklarew EVPP692/991

  2. Stream Food Web - Overview

  3. River Continuum Concept Sources of food for consumers change as stream order increases due mainly to physical factors like stream width and depth Consumer populations respond in a predictable manner as stream order increases reflecting changes in their food supply: in stream algae vs. local CPOM vs. upstream FPOM

  4. What about the photobionts? • Where are they? • How are they distributed in the watershed? • How have they structured these ecosystems?
