The Primary Difference Between the Small-Population Approach (S-PA)and the Declining-Population

question 62

Multiple Choice

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 the bringing together of individuals from scattered small populations to interbreed 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.
