How would you apply Simpson's Index to assess the impact of a new construction project on local biodiversity?

• Compare the index before and after construction to see if biodiversity has increased.

• Use the index to determine the number of new species introduced by the construction.

• Calculate the index only after the construction to determine the new biodiversity level.

• Calculate the index before and after the construction to determine any changes in biodiversity.

Interpret the following data: A study shows a percent change of -20% in the population of a species over 5 years. What does this indicate about the species' population?

• The population size is stable.

• The population size is increasing.

• The population size is decreasing.

• The population size is fluctuating.

How would you use the Lincoln Index to estimate the population of a species in a large forest area?

• Capture as many individuals as possible, mark them, and never release them back.

• Capture a sample of individuals, mark them, release them, and then recapture to estimate the total population.

• Only observe the animals from a distance to estimate the population.

• Use satellite images to count the number of individuals.

A biologist calculates the Simpson's Index of two areas: 0.75 and 0.85. What can be inferred about the biodiversity of these areas?

• Both areas have high biodiversity, but the area with 0.85 has higher biodiversity.

• Both areas have low biodiversity, but the area with 0.85 has slightly higher biodiversity.

• The area with 0.75 has higher biodiversity than the area with 0.85.

• It is impossible to determine biodiversity from Simpson's Index alone.

What does a range of 20 in a data set tell you about the variability of the data?

• There is no variability in the data.

• There is a moderate level of variability in the data.

• There is high variability in the data.

• The range does not provide information about variability.
