The red lionfish (shown below) 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?
El pez león rojo (que se muestra a continuación) es un depredador voraz de peces pequeños, incluidos los peces ángel y el pez loro.

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. 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 (including stoplight parrotfish, queen angelfish, yellowtail snappers, and Nassau groupers). 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?
En un arrecife frente a la costa de una isla grande, un aumento en la pesca con red reduce las poblaciones de la mayoría de los peces de arrecife (incluidos el pez loro de semáforo, el pez ángel reina, los pargos de cola amarilla y los meros de Nassau). Las pesadas redes también atrapan a las tortugas carey y dañan los corales. Suponiendo que el arrecife tiene una población saludable de erizos de mar de espinas largas, ¿cuál es el resultado más probable?
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?
Dos arrecifes están expuestos al patógeno de la enfermedad de la banda negra. El arrecife A está ubicado en un área remota frente a una costa rocosa que recibe poca lluvia. Reef B está ubicado cerca de un hotel resort, un campo de golf muy fertilizado y un bosque que ha sido talado recientemente para un desarrollo de viviendas. Ambos arrecifes están dominados por corales estrella. ¿Cuál es el resultado más probable de la enfermedad en cada arrecife?
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.
What is the most likely outcome of a disease that kills off the long-spined sea urchins on a reef?
¿Cuál es el resultado más probable de una enfermedad que mata a los erizos de mar de espinas largas en un arrecife?
Staghorn coral cover will increase.
Star coral cover will increase.
Sponge cover will increase.
Algae cover will increase.
