Questions and Answers

Which factor is MOST important in determining the priority of a population for conservation investment?

  • Conservation status and threats
  • Habitat quality and connectivity
  • Genetic diversity
  • Effective population size (correct)

    • How does habitat fragmentation affect the genetic diversity of a population?

  • Habitat fragmentation increases genetic diversity by promoting gene flow between isolated populations.
  • Habitat fragmentation has no effect on genetic diversity, as long as the total population size remains the same.
  • Habitat fragmentation increases genetic diversity by allowing for the emergence of new, genetically distinct subpopulations.
  • Habitat fragmentation decreases genetic diversity by limiting gene flow and increasing the risk of inbreeding. (correct)

    • If two populations have the same total population size, which one would be a higher priority for conservation investment?

  • The population with higher food availability and more shelter resources.
  • The population with lower population density and higher reproductive output.
  • The population with higher genetic diversity and more connectivity to other populations. (correct)
  • The population with lower genetic diversity and less connectivity to other populations.

    • How does food availability affect the population density of a species?
