4. In 1878, seal hunters introduced rabbits to Macquarie Island, between Australia and
Antarctica. The rabbit population soared and the Myxoma virus was then introduced to
kill off rabbits. It worked, but the islands’ cats, which had depended on the rabbits for
food, began eating seabirds instead. To save the seabirds, scientists started a program to
kill off the cats. Twenty-four years later, in 2009, the rabbit population had exploded
again, and rabbits were ravaging native plant species and devastating the island’s
ecosystem. This story appears to be an example of a. sound, responsible ecological
management.
b. unintended ecological consequences.
c. predictable but unavoidable consequences.
d. a series of catastrophes resulting from random chance.

5. What evidence led Ruth and Sessions to conclude that parasites could be the cause of
some of the deformities in the frogs found in the ponds of Northern California?
a. None of the deformed frogs found in the ponds were infected with the parasites.
b. They directly observed the parasites causing the deformities.
c. Glass beads placed near the location of limb development in tadpoles mimicked the
effect of parasites and caused deformities.
d. Deformities in the frogs occurred in nature but not in the laboratory.

The figure is based on Johnson’s experiment on the effects of trematode parasites on
tadpoles. Which statement best describes the control group in the experiment? a.
Tadpoles were grown in the absence of trematode parasites.
b. Tadpoles were allowed to grow in nets in their natural environment.
c. Tadpoles were grown in the presence of only one trematode parasite.
d. Tadpoles were grown in a tank in which the concentration of trematode parasites was
similar to the parasite concentration of ponds in which deformed frogs were found.

The figure is based on Johnson’s experiment on the effects of trematode parasites on
tadpoles. Which claim is supported by the figure?
a. As the number of parasites that the tadpoles were exposed to decreased, the percentage
of surviving frogs with deformities increased.
b. As the number of parasites that the tadpoles were exposed to increased, the percentage
of surviving tadpoles decreased.
c. If there were no parasites present, 100% of the tadpoles survived to metamorphosis.
d. Tadpoles with moderate levels of parasites had the lowest percent of deformities in
adults.
