In a mark-recapture study, an ecologist traps, marks, and releases 25 voles in a small wooded area. A week later she traps 30 voles, 10 of which are marked. What is her estimate of the vole population in that area?

Expert Solution & Answer

Summary Introduction

To determine: The approximate population of vole in the given area by the mark-recapture method.

Introduction: An ecologist traps, marks, and releases 25 voles in a small wooded area. The ecologist again traps 30 voles after a gap of one week and observes that 10 of them have the mark.

Explanation of Solution

The vole population can be calculated by the formula given below:

Estimated population size (N) =snx (I)

Here, N is the estimated size of the population, s is the number of animals initially marked and released, n is the number in second sampling, and x is the recaptured marked animals.

Substituting the values of s=25, n=30, and x=10 in equation (I) to find the estimated population size of voles.

N= 25×3010N=75 voles

The estimated population size (N) of voles is 75 voles.

Conclusion

Thus, the estimated size of the vole population in the given area is 75 voles.

After you feel comfortable with your counting method and identifying cells in the various stages of mitosis, use the four images below of whitefish blastula to count the cells in each stage until you reach 100 total cells, recording your data below in Data Table 1. (You may not need to use all four images. Stop counting when you reach 100 total cells.) After totaling the cells in each stage, calculate the percent of cells in each stage. (Divide total of stage by overall total of 100 and then multiply by 100 to obtain percentage.) Data Table 1Stage Totals PercentInterphase Mitosis: Prophase Metaphase Anaphase Telophase Cytokinesis Totals 100 100% To find the length of time whitefish blastula cells spend in each stage, multiply the percent (recorded as a decimal, in other words take the percent number and divide by 100) by 24 hours.
