Be familiar with Population Case Studies (Articles): CA Sea Otter and CA Condor. 2. What levels of complexity make up the biosphere? 3. How do populations and communities differ? 4. What factors regulate the size of a population? 5. Explain Gause’s findings in his experiments 6. What is the difference between density-dependent and density-independent factors that influence population size? Give example of each. 7. Compare and contrast the exponential growth model and the logistic growth model. 8. Define metapopulation. How do metapopulations contribute to the preservation of biodiversity? 9. What are the various ways in which species interact with each other? 10. What are the four types of predators? 11. What roles might keystone species play in an ecosystem? 12. How are species distributed globally, and what processes are responsible for these patterns? 13. What are the four factors that determine the number of species found in a community? 14. What does the theory of island biogeography describe? 15. What is the process of ecological succession? 16. Explain how does latitude, time, area, and distance affect the species richness of a community.
