How to fill out grasshopper mark-recapture lab

How to fill out grasshopper mark-recapture lab:

1. Start by setting up the trapping area. This can be done using a large mesh net or a pitfall trap.
2. Capture a few grasshoppers from the area and mark them with a non-toxic marker or with numbered tags. This will allow you to identify them later on.
3. Release the marked grasshoppers back into the trapping area and allow them to mix with the population.
4. After a set amount of time, recapture a new sample of grasshoppers from the area using the same trapping method.
5. Record the total number of grasshoppers captured in the recapture sample and the number of marked grasshoppers recaptured.
6. Use the mark-recapture formula to estimate the total population size of grasshoppers in the area. This formula involves dividing the number of marked grasshoppers initially captured by the proportion of marked grasshoppers in the recapture sample.
7. Repeat this process multiple times and calculate the average population size estimate for more accuracy.
