Question 2

A lizard is blown out to sea during a hurricane. This type of storm occurs very infrequently-on average once every 100 years. The lizard washes up on the beach of a small island and finds some beetles on the beach. Individual beetles on the island vary in size. It takes the lizard the same amount of energy to catch a beetle, regardless of the size of the beetle. Which beetle does optimal foraging theory predict the lizard will eat most frequently?

Accepted Answer

A)  Beetles that are smaller than average 
B)  Beetles that are average size 
C)  Beetles that are bigger than average 
D)  The size of the beetles is unlikely to affect the lizard's foraging preferences.

Question 6

Refer to the figure.
  Based on the figure, which of the following statements is false?

Accepted Answer

A)  If there is a group of two individuals, a lone individual would benefit from joining the group, but the original members of the group would be harmed. 
B)  If there is a group of two individuals, a lone individual would benefit from joining the group and the original members of the group would benefit as well. 
C)  If there is a group of five individuals, a lone individual would benefit from joining the group, but the original members of the group would be harmed. 
D)  If there is a group of seven individuals, a lone individual joining the group would harm both the new group member and the original group members.

Question 7

Refer to the figure.
Figure 2
   You are studying four bird species to determine the differences between poor-quality and high-quality males.
- You collect the data shown in Figure 2. Suppose some females are not very skilled at detecting small differences in tail length. When they perceive a difference in tail length, these females always choose the males with the longer tails. Assuming that high-quality males do have longer-than-average tails, in which species would females be most likely to correctly assess male quality by tail length? Why? In which group might you expect these females to make the most assessment mistakes? Why?

Accepted Answer

Females not skilled at detecting small d
