Chapter 58, Problem 1A
Historically, island species have tended to become extinct faster than species living on a mainland. Which of the following reasons can be used to explain this phenomenon?
a. Island species have often evolved in the absence of predators and have no natural avoidance strategies.
b. Humans have introduced diseases and competitors to islands, which negatively affect island populations.
c. Island populations are usually smaller than mainland populations.
d. All of the choices are correct.

The best argument for how an unprotected species can evolve to mimic a second protected species (distasteful or noxious) and thus obtain protection is by
A. Random changes in the appearance of the unprotected species that lead to increased fitness due to greater similarity with the protected species
B. Individuals deciding that they need protection and mutating to look like the protected species

D. Natural selection for more advanced traits that are better to the inferior traits of organisms that do not look like the protected species
E. Behavioral modification of the unprotected species to act like the protected species

The researcher finds that, in one year, 34 were born, 86 died, 12 migrated into the marsh, and there was no emigration. a. frogs are considered an indicator species for the quality of the environment.
