A. Survival likelihood of daughters
B. Survival likelihood of sons
C. Reproductive success of daughters
D. Reproductive success of sons
E. All of the above

Answer 3

D. Reproductive success of sons

Question 4

Choose the best answer to complete the sentence: Endemic species…

A. Tend to be invasive species.
B. Are more vulnerable to extinction due to their limited geographic range
C. Only exist in one geographic location, and thus do not contribute
substantially to global biodiversity
D. Are clustered near the poles because they evolved since the last
ice age and have not yet migrated towards the equator.

Answer 4

B. Are more vulnerable to extinction due to their limited geographic range

Question 5

Three processes affect gamma diversity of a region – speciation, extinction, and migration. Which of the following sets of processes would lead to increased diversity in a region:

A. High rate of speciation, low rate of extinction, no species moving in or out.
B. Low rate of speciation, high rate of extinction, no species moving in or out.
C. Equal rates of speciation and extinction, low rate of immigration (species
moving in), high rate of emigration (species moving out)
D. Equal rates of species and extinction, no species moving in or out

Answer 5

A. High rate of speciation, low rate of extinction, no species moving in or out.

Question 6

Which of the following habitats is most likely to have the highest
ECOLOGICAL diversity?

A. Arctic tundra located at 60°N
B. Desert located at 30°N
C. Temperate rainforest located at 30°S
D. Tropical rainforest located at 0°N/S (the equator)

Answer 6

D. Tropical rainforest located at 0°N/S (the equator)

Question 7

Why is plant species richness affected by the frequency of
disturbances?

A. Few species are able to tolerate the environmental conditions
associated with frequent disturbances
B. Infrequent disturbance allows slow-growing species to establish and
reduces survival likelihood of most other species.
C. Frequent disturbances increase the likelihood that r-selected
species will grow.
D. A & B
E. All of the above

Answer 7

E. All of the above
