The red lionfish is a voracious predator of small fish, including young angelfish and parrotfish. In the Caribbean, red lionfish have no natural predators. What is the most likely long-term outcome of the introduction of lionfish to a pristine reef?

• The numbers of stoplight parrotfish and queen angelfish will decrease.

• The numbers of yellowtail snappers and Nassau groupers will decrease.

• The number of long-spined sea urchins will increase.

• All of the above

A spike in the popularity of Nassau groupers in American restaurants causes a sharp increase in grouper fishing. How will this affect the population of yellowtail snappers?

• The number of yellowtail snappers will increase.

• The number of yellowtail snappers will decrease.

• The number of yellowtail snappers will decrease at first, and then increase.

• There will be no effect on yellowtail snapper populations.

In a reef off the coast of a large island, an increase in net fishing lowers the populations of most reef fish. The heavy nets also trap hawksbill sea turtles and damage corals. Assuming the reef has a healthy population of long-spined sea urchins, what is the most likely result?

• Coral cover will increase.

• Sponge cover will increase.

• Algae cover will increase.

• Coral, sponge, and algae cover will remain the same.

Two reefs are exposed to the black band disease pathogen. Reef A is located in a remote area off a rocky coast that receives little rainfall. Reef B is located near a resort hotel, a heavily fertilized golf course, and a forest that has been recently clearcut for a housing development. Both reefs are dominated by star corals. What is the most likely outcome of the disease on each reef?

• Reef A will suffer greater damage than reef B.

• Reef B will suffer greater damage than reef A.

• Both reefs will suffer equal damage from the disease.

• Neither reef will be affected because black band disease affects only branching corals.
