FLORIDA BAY SEAGRASS MODELER DATA NEEDS

Unit Model

1. Nutrient kinetics (N&P) leaf vs root Tt & Hw (Lee and Dunton Tt and N only, Koch for Tt and P)

2. Light-Photosyn relationships (Fourq 1991, Haunert workshop, Carlson light station, Tomasko and Dunton, Durako and Kuss 1994, Williams and McRoy)

3. Sediment chemistry- %OM, Fe, sulfide, Eh, NH4+, [P], pH, [Fl] depth profiles

4. Sediment depth and granulometry-porosity, permeability (Carlson, Zieman et al., 1989, Robblee, Davies)

5. Salinity/Temp - photosynthesis relationships (Fourq thesis, Haunert and Kenworthy, Durako Tt and Rm, Barber and Behrens, Zieman 75, Bittaker and Iversen Mar Biol)

6. Transport rates (O2 & CO2, etc,) and carbon allocation- (Andorfer N in Tt, 14C Bittaker and Iverson MarBiol)

7. Nutrient pools within plants - (Carbs - Dawes etal, N:P Fourq, Zieman turtle paper) Senescence-remobilization

8. Epiphytes - loads etc. (Frankovich, Tomasko)

9. Respiration rates- shoots vs rhizomes (Fourq thesis, Fourq and Durako EPA light study)

10. Leaf morphometrics/allometrics - FHAP- Hackney, Fourq & Zieman 83/84

11. Chlorophyll distribution along leaf

12. Leaf angle - Eva Koch, Fonseca, Mimi Koehl, Zimmerman , Denise Heller Thesis UVa

13. Flow effects, Boundary Layer, (Florence Thomas- USF Ecology, Koch, Heidi Nepf

14. Labyrinthula effects on photosynthesis and O2 flux-spread across beds

15. Rhizome elongation and branching rates (Kaldy Tt, Fonseca and Kenworthy (Stella model) Keys transplants, FHAP)

16. Reproductive allocation - flowers, fruits and seeds (FHAP, Fourq student FIU, Petersen et al. FKNMS up to 10% flower)

17. Recruitment & Mortality (FHAP, FKNMS)



Landscape Model - spatially explicit GIS based

1. Distribution of N & P (Szmant data , Old Fourq data)

2. Distribution of Light - spatial and temporal Kd/basin (AVHRR, Carlson light station, FHAP spring and fall, SERP data)

3. Distribution Sediment chemistry- %OM, Fe, sulfide, Eh, NH4+, [P], pH, [Fl]; depth profiles

4. Distribution of sediment depth granulometry-porosity, permeability (Prager & Halley, Wanless et al., Stockman and Shinn, Enos, Bosence

5. Salinity/Temp Distribution

6. Distribution of Labyrinthula

7. Distribution of flowering
