Measuring Biodiversity

Which of the following is a common method for measuring biodiversity? A) Counting individual species B) Measuring the height of trees C) Calculating the average temperature D) Assessing soil pH levels.

• Counting individual species

• Measuring the height of trees

• Calculating the average temperature

• Assessing soil pH levels

Why is it important to determine the level of biodiversity in an area?

• To inform decisions on how the area should be treated

• To increase the number of species

• To decrease the number of species

• To eliminate all species

What is the purpose of using sampling in measuring biodiversity?

• To save time, money, and practicality

• To count all individuals

• To eliminate bias

• To reduce sample size.

Which of the following is a requirement for samples in biodiversity measurement?

• Samples should be biased

• Sample sizes should be small

• Samples should be unbiased

• Samples should ignore species abundance.

Which of the following is a method for measuring species diversity?

• Percentage cover

• Habitat fragmentation

• Climate change

• Genetic mutation

What does 'Percentage frequency' measure in the context of species diversity?

• The number of species in a given area

• The proportion of plots in which a species occurs

• The genetic variation within a species

• The total biomass of a species

Species richness is a measure of:

• The total number of individuals in a species

• The number of different species in a given area

• The genetic diversity within a species

• The average size of individuals in a species

Species abundance and evenness refer to:

• The total biomass of a species

• The distribution of individuals among species

• The genetic variation within a species

• The number of species in a given area

Simpson’s diversity index is used to measure:

• The genetic diversity within a species

• The probability that two individuals randomly selected from a sample will belong to different species

• The total number of species in a given area

• The average size of individuals in a species

What is 'Percentage Cover' used for?

• Estimating the abundance of animals

• Estimating the abundance of organisms, generally plants or fixed organisms

• Measuring the height of trees

• Calculating the weight of plants.
