1. Pacific salmon or annual plants illustrate which of the following?

semelparous

2. Which of the following describes having more than one reproductive episode during a lifetime?

iteroparous

3. Density-dependent factors are related to which of the following?

Allee effect

4. Which of the following is true?

r and K-selection are two extremes of a range of life history strategies

5. The life history traits favored by selection are MOST likely to vary with

population density

6. In which of the following habitats would you expect to find the largest number of K-selected individuals?

the flora and fauna of a coral reef in the Carribean

7. Which of the following characterizes relatively K-selected populations?

Offspring with good chances of survival

8. Which of the following statements about the evolution of life histories is correct?

Most populations have both r and K-selected characteristics that vary under different environmental conditions

9. Your friend comes to you with a problem. Is seems his shrimp boats aren't catching nearly as much shrimp as they used to. he can't understand why because originally he caught all the shrimp he could handle. Each year he added a new boat, and for along time each boat caught tons of shrimp. As he added more boats, there came a time when each boat caught somewhat fewer shrimp, and now, each boat is catching a lot less shrimp. Which of the following topics might help your friend understand the source of his problem?

Density-dependent population regulation and intrinsic characteristics of population growth

10. Carrying capacity is

the maximum population size that a particular environment can support
