A teаm оf ecоlоgists is studying а populаtion of snails in a marsh. During the first sampling, they capture and mark 120 snails before releasing them back into the population. A week later, they recapture 150 snails, 30 of which are marked. A) Calculate the size of the snail population. Show all calculations. After carefully observing the recaptured animals, the researchers discovered that 10% of the marked snails actually lost their marks during the study period. B) Adjust the population estimate to account for this mark loss. Show all calculations. Hint: The true number of marked snails in the second sample (R′) can be recalculated as: R′=R/(1−Mark Loss Rate). Answer parts A and B.
