The primary difference between the small-population approach (S-PA)and the declining-population approach (D-PA)to biodiversity recovery is
A) S-PA is interested in bolstering the genetic diversity of a threatened population rather than the environmental factors that caused the population's decline.
B) S-PA kicks in for conservation biologists when population numbers fall below 500.
C) D-PA would likely involve bringing together individuals from scattered small populations to interbreed in order to promote genetic diversity.
D) S-PA would investigate and eliminate all of the human impacts on the habitat of the species being studied for recovery.
E) D-PA would use recently collected population data to calculate an extinction vortex.

Question

Quizplus · Accepted Answer

The primary difference between the small-population approach (S-PA) and the declining-population approach (D-PA) to biodiversity recovery is that S-PA focuses on improving the genetic diversity of a threatened population, while D-PA aims to address the environmental factors that led to the population's decline. Therefore, option A is correct.

B is incorrect because there is no fixed number when the S-PA kicks in; C is incorrect because it describes a process that could be used in either approach; D is incorrect because it is not specific to S-PA or D-PA; and E may or may not be a part of either approach, but it is not the primary difference between them.
