  1. THE LITTORAL ZONE ALGAE AND ZOOPLANKTON

  2. Attached algal habitats in a generalized river ecosystem

  3. Algae and bacteria on a sand grain

  4. Diagram of an epiphyte biofilm and nutrient flow within the community

  5. SEM micrographs of periphytonbiofilms on Chara

  6. Model of a periphyton community showing relationships between algae and bacteria

  7. Intact biofilm showing clusters of algae and bacteria

  8. Model of interactions between phytoplankton/ bacterioplankton and epiphytic algae & bacteria

  9. Comparison between periphyton habitats relative to surface areas for attachment

  10. Variations in particle size around an obstacle in a stream

  11. As periphyton communities develop, nutrient demand increases but diffusion rates from the water decreases

  12. Seasonal variation in epipelic diatoms and cyanobacteria in two English lakes

  13. Seasonal carbon content of epiphytes on Scirpussubterminalisin Lawrence Lake

  14. Generalized relationship between submerged macrophytes and periphyton

  15. Interactions between the littoral zone and open water in lakes

  16. Spatial variations in periphyton

  17. Primary production of periphyton and phytoplankton

  18. Epipelic algal production in Marion Lake, BC

  19. Periphyton production on emergent and submerged epiphytes

  20. Model of macrophyte, periphyton, and phytoplankton production in a lake

  21. Number of littoral-dominated versus pelagic-dominated lakes on earth

  22. Chydorids in beds of Scirpussubterminalis

  23. Wetzel’s Summary
