1. What is the carrying capacity for moose in the simulation model of Isle Royale, prior to any changes in the weather?


2. When the wolves arrived on Isle Royale, what did they find?
a. A small healthy moose population.
b. A small unhealthy moose population.
c. A large unhealthy moose population.
d. A large healthy moose population.

3. According to your experiments, if the plant growth rate on Isle Royale suddenly were to increase a great deal, which of the following would likely be true?
a. The moose and wolf population maximum values would increase.
b. The moose and wolf population minimum values would decrease.
c. The probability of extinction would increase.
d. All of the above.

4. Logistic population growth is characterized by all but which one of the following statements?
a. A maximum rate of population growth.
b. A carrying capacity.
c. A large overshoot of the carrying capacity.
d. A net population growth rate that can be close to zero.

5. What happens when plant growth is doubled in the simulation model?
a. The moose and wolf populations stop cycling.
b. The moose and wolf populations continue cycling as before.
c. The moose and wolf populations continue cycling, but the cycles are smaller.
d. The moose and wolf populations continue cycling, but the cycles are larger.

6. Based on your data, if you added 500 moose to the Isle Royale population in the simulation model, without any wolves present and with a normal growing season, and then you waited 50 years, the moose population size would be approximately:


7. Without wolves, what did you observe as the average value for moose fat stores in your simulated experiment?


8. The moose and wolf population cycling is best described by which of the following statements?
a. Wolf population sizes increase after moose population sizes increase, and wolf population sizes decrease after moose population sizes decrease.
b. Wolf population sizes increase and decrease at the same time as moose population sizes.
c. Wolf population sizes increase after moose population sizes decrease, and wolf population sizes decrease after moose population sizes increase.
d. Wolf population sizes increase only when moose populations are at their peak size, and wolf population sizes decrease only when moose populations are at their lowest size.

9. What does the carrying capacity for moose on the island primarily depend on?
a. The amount of food available.
b. The amount of water and cover available.
c. The density of moose.
d. None of these.

10. How does the average energy level of moose change with the introduction of wolves?
a. Average moose energy falls.
b. Average moose energy rises.
c. Average moose energy stays the same.
d. It depends on how many wolves were introduced.
