Presentation Transcript

  1. Littoral macro-invertebrates and zooplankton • Zooplankton Methods-Freddy Haberman • Zooplankton Results-Jonathon Schriendel • Macro-invertebrate Methods-Erin Landers • Macro-invertebrate Results-Brita Olson • Fish- Erin Landers

  2. Methods: Zooplankton Samples

  3. Zooplankton Sampling Methods • Samples were taken from the deepest point in the pond • Schindler Trap and Closing Plankton Net were used • Closing Plankton Net was used to take full water column samples

  4. Sampling Methods Cont. • Schindler Trap was used to take samples from 3 different depths in the pond • Surface, 0.5 & 1 meter depths

  5. Zooplankton Analysis • Each sample was poured in a gridded petri dish & examined under a dissecting microscope • Organisms that were found during analysis were identified & counted

  6. Results: Zooplankton Community

  7. Full column zooplankton samples

  8. Discrete zooplankton samples

  9. Methods: Macro-invertebrate Littoral Samples

  10. Sites 3 4 2 1

  11. Materials • Dip net • Sieve stack and filter tubes • Lots of DI water! • Sample vials

  12. Collection Methodology • 4 sites • 3- meter long pulls at each site • Filter and collect • Store until analysis

  13. Lab Methodology • Preserve samples with formalin • Separate out a sub sample • Identify and count macro-invertebrate organisms

  14. Results: Macro-invertebrate Community
