1. Most scientists suspect that that reason for the dramatic population crash of the snowshoe hare is:
a. the decline of winter forage (food).
b. an epidemic disease
c. all of these choices are correct
d. that when swimming, hares cannot distinguish small lakes from large lakes, so they drown
e. an increase in territoriality
2. An area occupied by a mammal that it defends against invasion by other members of the same species is called its:
a. Home range
b. Burrow
c. Territory
d. Foraging area
e. Both A and B are correct
3. Generally, in cases of polygamy, male birds are smaller and more colorful (but at greater risk to predators) while females are larger (with more nutritional resources) and duller colored (and therefore more camouflaged). In such a system, the female invests much in her young while the male tries to spread his genes as much as possible.
In the opposite and very rare system of polyandry, the male may invest in caring for his young in one nest while the female does not care for the young but travels around to court males and spread her genes as much as possible. In such a case, we should expect:
a. The male bird would be smaller but camouflaged
b. The male bird would be larger and camouflaged
c. The male bird would be larger and more brightly colored
d. None of the choices are correct
e. The female bird would be larger to provide energy for all the flying
4. Archaeopteryx is:
a. An insect-eating bird that is rare in the United States but somewhat common in South America
b. A hoax made to resemble an intermediate between reptiles and birds
c. An extinct "bird-like" dinosaur
d. A primitive therapsid from which birds eventually evolved
e. The most primitive of the living birds
