Explicit model of ecosystem behavior #1

Explicit model of ecosystem behavior #1 Eutrophication will lead to changes in relative abundances of primary producers in a predictable way. . Explicit model of ecosystem behavior #2 Eutrophication will shift N:P ratios of primary producers towards a taxon-specific “Redfield ratio”.

Presentation Transcript


  1. Explicit model of ecosystem behavior #1 Eutrophication will lead to changes in relative abundances of primary producers in a predictable way.

  2. Explicit model of ecosystem behavior #2 Eutrophication will shift N:P ratios of primary producers towards a taxon-specific “Redfield ratio”

  3. Explicit model of ecosystem behavior #3 Eutrophication will shift seagrass d13C towards more negative values because of increased discrimination against 13C in low light conditions

  4. Not-so-Explicit model of ecosystem behavior #4 Eutrophication will cause some kind of change in d15N of primary producers

  5. Control Treatment 25cm x 25cm randomly placed for benthic coverage 25cm x 25cm set sites for benthic coverage Elemental ratio, stable isotope sampling 10cm x 10cm randomly placed for canal wall coverage

  6. We will also specifically identify and count the conspicuous fish and invertebrates along each transect
