PE 6.1c: Milkweed Bug Hatching Investigation Results And Conclusion

Results Summarize what you found out about the limiting effect of the three variables studied in the milkweed-bug hatching experiments.

Conclusions Discuss the significance of the experimental results. What do the results suggest about ways that milkweed-bug populations are limited in nature?

PE 6.2: Algae and Brine Shrimp Experiments

1.Based on the experimental results, what factor(s) placed limits on the algae populations? What is your evidence? 2. Based on the experimental results, what factor(s) placed limits on the brine shrimp populations? What is your evidence? 3. What additional abiotic and biotic factors might limit population size of brine shrimp and planktonic algae in Mono Lake? (T-Charts?)

PE 6.3: Analysis of Mono Lake Data

1. When does the planktonic algae population peak 1. When does the planktonic algae population peak? When does the brine shrimp population peak? What explanation do you have for the timing of each peak? 2. What is the relationship between water temperature and the other organisms in the Mono Lake ecosystem? 3. Discuss the population graphs of the birds (gulls, phalaropes, and grebes). 4. What is the relationship between the birds and the other organisms? 5. What do you think is going on with the populations at Mono Lake in April?
