Assisted Migration Conservation

Listen to part of a lecture in a Conservation Biology class.

 



  1. What is the main purpose of the lecture?
  • A. To explain the government’s role in the regulating assisted migration.
  • B. To discuss ways in which plants and animals adapt to climate change.
  • C. To discuss a controversial approach to conserving plant and animal species.
  • D. To describe a recently discovered consequence of global warming.

 

  1. According to the professor, what problem is assisted migration intended to overcome?
  • A. To diminishing amount of undeveloped land that species can migrate through.
  • B. The relative lack of nutrients available in cooler latitudes and higher elevations.
  • C. The increase in alternations between cool and warm periods.
  • D. Competition from other species in certain native habitats.

 

  1. What point does the professor make when she discusses the cane toad?
  • A. Translocated species sometimes die out from lack of food.
  • B. Translocated species may spread too quickly in their new environment.
  • C. Several techniques are available to achieve assisted migration.
  • D. Animal species are often easier to translocate than plant species are.

 

  1. What does the professor imply when she mentions translocating networking of species?
  • A. There are aspects of interdependency that are unknown.
  • B. Some species evolve in ways that help them survive in new habitats.
  • C. It is difficult to know how far to move a network of species from its native habitat.
  • D. Many assisted-migration plans should involve the translocation of just one species.

 

  1. What does the professor imply about the government’s role in regulating assisted migration in the United States?
  • A. The government should continue to encourage assisted migration.
  • B. The government has created policies that have proved unhelpful.
  • C. The government should follow the example set by other countries.
  • D. The government needs to increase its involvement in the issue.

 

  1. What is the professor’s attitude toward the effort to save the Florida torreya?
  • A. She is glad that some conservationists are willing to take a chance on assisted migration.
  • B. She is concerned because it may have unintended consequences.
  • C. She is surprised because other species are more endangered than Florida torreya is.
  • D. She expects the effort will have to be repeated several times before it succeeds.
