Questions

Question 1 Multiple Choice (Single Answer)

What is the primary goal of population viability analysis?

  1. To estimate the size of a population
  2. To predict the future trajectory of a population
  3. To identify the factors that are affecting a population
  4. To develop strategies for managing a population
Question 2 Multiple Choice (Single Answer)

Which of the following is NOT a factor that is typically considered in population viability analysis?

  1. Habitat loss
  2. Predation
  3. Competition
  4. Weather
Question 3 Multiple Choice (Single Answer)

What is the difference between a deterministic and a stochastic population viability analysis?

  1. Deterministic models assume that all parameters are constant, while stochastic models allow for variability.
  2. Deterministic models are more accurate than stochastic models.
  3. Stochastic models are more complex than deterministic models.
  4. Deterministic models are used to predict the future trajectory of a population, while stochastic models are used to assess the risk of extinction.
Question 4 Multiple Choice (Single Answer)

What is the minimum viable population size?

  1. The smallest population size that can persist over the long term without going extinct
  2. The largest population size that can be supported by the environment
  3. The average population size over a period of time
  4. The population size at which the birth rate and death rate are equal
Question 5 Multiple Choice (Single Answer)

What is the difference between a population viability analysis and a risk assessment?

  1. Population viability analysis is used to predict the future trajectory of a population, while risk assessment is used to identify the factors that are affecting a population.
  2. Population viability analysis is used to assess the risk of extinction for a population, while risk assessment is used to identify the factors that are affecting a population.
  3. Population viability analysis is used to develop strategies for managing a population, while risk assessment is used to identify the factors that are affecting a population.
  4. Population viability analysis is used to assess the risk of extinction for a population, while risk assessment is used to predict the future trajectory of a population.
