Lincoln Index

Which of the following is NOT a step in the capture-mark-recapture process?

• Marking individuals in the first sample.

• Releasing marked individuals back into the population.

• Recapturing individuals after a long period of time.

• Counting the number of marked individuals in the second sample.

A method to estimate the population size of mobile species

Which of the following techniques would best be used to estimat population size of organisms that move around?

• Lincoln Index

• Simpson's Index

• Quadrat Sampling

• Transect Sampling

Which of the following are correct assumption when calculating the Lincoln Index? (Three Boxes Needed)

• Closed population

• Individuals isolate themselves after being marked

• Individuals are mobiles and can be caught

• Organisms have an equal chance of being caught

To calculate the population size of wolverines in the Northern Forests of Canada, 8 were initially caught, marked and released, allowed to reintegrate. 9 wolverines were caught the second time, of which 3 were marked. How big is the population?

• 28

• 22

• 24

• 20

Which of the following would be an appropriate use of a Pitfall Trap? (Three Boxes needed)

Which of the following is NOT an assumption of the Lincoln Index method?

• The population is closed with no immigration or emigration.

• Marked individuals mix evenly back into the population.

• All individuals have an equal chance of being captured.

• The population size is constant over time.

The Lincoln Index is primarily used to estimate the population size of which type of organisms?

• Sessile organisms

• Mobile organisms

• Aquatic plants

• Fungi

In the Lincoln Index formula, what does the variable 'M' represent?

• Total number of individuals captured in the second sample

• Total number of marked individuals in the first sample

• Total number of marked individuals recaptured

• Total population size estimate

Which of the following scenarios would violate the assumptions of the Lincoln Index?
