Hey gang, here are some practice multiple choice questions to hone your exam skilz. I’ll post answers on Sunday morning. Ignore the fact that the numbers on the questions are not always sequential. NOTE: Information covered in lecture that is not on this practice exam MAY be on the final. On the final, expect to see some graphs or tables of data, and be ready to answer questions about them. 1. Consider a study of a group of vultures all born at the same time. If 1000 out of 2000 die between the age of 0 and 1 and 100 out of 200 die between the age of 10 and 11, which statement about their life history do we have the most evidence for? a. vultures are semelparous b. vultures have a type II mortality curve c. the vulture population is shrinking over time d. vultures do not reproduce before the age of 2 e. vultures have a short generation time 2. The equilibrium population size of a species in the absence of interspecific competitors or predators is a. the size at which the growth rate = 0 b. K c. the maximum population size the environment can sustain d. the population size at which dN/dt = 0 (where N refers to the population size) e. all of the above are correct 3. Which of the following would NOT affect the birth rate of a population? a. age of first reproduction b. post-reproductive mortality c. generation time d. number of offspring produced per reproductive event e. pre-reproductive mortality 4. In the logistic growth model, growth rates ____________ as population density increases, due to the effects of ___________. a. increase / unlimited resources b. decrease / interspecific competition c. increase / interspecific competition d. decrease / intraspecific competition e. increase / intraspecific competition 5. All of the following are differences between the exponential and logistic models of population growth EXCEPT a. The exponential assumes unlimited resources; the logistic does not b. At a given N, per capita growth rate is higher with the logistic than the exponential model. c. The logistic has an equilibrium; the other does not. d. In the exponential model, dN/dt is constant, but in the logistic dN/dt decreases as N increases.

e. In the exponential model, K determines dN/dt. 6. The pattern of dispersion for a certain species of kelp is clumped.
