The primary difference between the small-population approach and the declining-population approach to biodiversity recovery is that ________.

#Unit 9. Diversity of Life Forms

  1. small-population approach is interested in bolstering the genetic diversity of a threatened population rather than the environmental factors that caused the population's decline

  2. small-population approach applies for conservation biologists when population numbers fall below 500

  3. declining-population approach would likely involve bringing together individuals from scattered small populations to interbreed in order to promote genetic diversity

  4. small-population approach would investigate and eliminate all of the human impacts on the habitat of the species being studied for recovery
