Study Questions 8

Go back and study material from week 7 questions. The material from that week will be fair game on the quizzes for week 8. (Because it all ties in together). Also look over the two lectures from this week.


1. What is the model for the change in population size limited by resources? How is it different from exponential growth? Also graph population size vs time for this type of growth.


2. What happens to this equation when you add another competing species? How does this change the above graph?


3. What happens when you add predators? Graphically?


4. What are r- and K- selection? What life history characters are favored in each?


5. Are r- and K- selection useful ways to characterize a species? Explain.


6. Is the California Condor r- or K- selected? Explain why.


7. Which of its life history characteristics are more r-selected and which are more K-selected?
