Data are generated that follow relationships
taken from the recent botanical literature.
Systems simulated include:

1. Light attenuation by plant canopy

2. Near ground temperature profiles

3. Spruce stand temperature profiles

4. Photosynthesis and radiation

5. Leaf acidity & time of day

6. C4 and C3 photosynthesis

7. Carbohydrate storage in Vaccinium

8. Ranunculus CO2 assim. & temperature

9. Resp. & temp. in oak and beech

10. Frost exposure & photosynthesis in fir

11. Light intensity & photosynthesis

12. Ranunculus leaf area & light levels

13. Dark respiration & altitude

14. Cold pretreatment & budbreak

15. Gas exchange & temperature in 4 species

16. Frost resistance in Vaccinium

17. Soil depth & daily temperature

18. Soil depth & annual temperature

19. Moisture and photosynthesis/resp.

20. Saltwater & seed germination

Plant Biology Data Simulation

(Program No. 108-32W or No. 108-32M)

for WINDOWS ( NT, 98, Me, Xp) or Macintosh (Classic, OS X)

$ 69.95

Algal Growth Simulation

(Program No. 100-32)

for WINDOWS (NT, 98, Me, Xp)

$ 39.95

Program simulates effects of nitrates, phosphate, turbidity, pH,
temperature, ammonia, alkalinity, and light on the growth of algae. In
addition, periphyton photosynthesis is simulated under different
temperatures, different CO2 levels, and for 'light-adapted' and 'shade-
adapted' communities. Same format as other simulations, but does not
include 25 different systems.
