BIO 322 Test Questions with Complete Solutions
Efforts to recover populations of the red wolf, Canis rufus, are controversial because
the red wolf may be the result of gray wolf-coyote hybridization rather than a true species
Under which species concept is the total number of recognized species likely to be largest?
Phylogenetic species concept
A species that is geographically limited to only one defined area is referred to as
endemic
Which of the following is NOT a plausible explanation for the mismatch between the
predicted number of extinctions and the number of extinctions actually observed in historic
times?
No one has bothered to try to document actual extinctions.
Which of the following statements regarding the diversity of life is NOT supported by the
data shown in the figure?
Crustaceans are more diverse than arachnids
Using the following figure, which of the following statements is NOT consistent with the
patterns revealed by the fossil record?
Humans are currently causing a sixth mass extinction event. (we may be but theres no evidence
in the fossil record yet)
, According to the figure below, which of the following groups has the greatest rate of
extinction risk (measured as the percentage of species considered vulnerable, imperiled,
critically imperiled, or possibly extinct)?
Animals (both vertebrates and invertebrates) associated with freshwater habitats
Which of the following statements best describes the species-area relationship in the figure
below?
Larger areas tend to harbor more species than smaller areas, but the rate at which new species
accumulate decreases when moving from very small to larger and larger areas.
Imagine that the starting point is 3,000 hectares (ha) and a landowner decides to convert
2,000 ha of that remaining area to a giant soybean field. According to this graph below,
approximately how many of the original species are predicted to become extinct as a
result?
About 12 species will become extinct.
Although widely used, the species-area approach to predicting extinctions is likely to
overestimate the actual extinction rate, because
the amount of area that must be destroyed to kill the last individual of a species is almost always
much greater than the amount of area that would have to be destroyed to encounter the first
individual of a species.
Based on the data presented in the figure below, which species exhibit greater genetic
diversity than humans?
Rats (Rattus norvegicus) and Syrian hamsters (Mesocricetus auratus)
