About the Mark-Recapture (Lincoln-Petersen)

The Mark-Recapture (Lincoln-Petersen) is a dedicated tool in our Biology category designed to help you estimate population size in seconds. By automating the underlying mathematics, this utility eliminates manual calculations and provides reliable, instantaneous estimations.

Mathematical Principles & Calculation Steps

To compute the results, the calculation engine processes your custom inputs: Marked First Capture, Total Captured Second, Recaptured (marked). Specifically, the calculations are evaluated using the standard relationship: N = (M × C)/R. All computations are performed locally within your secure browser session, ensuring absolute data privacy and instantaneous updates without any network delay.

Worked Step-by-Step Calculation Example

Worked Example Sandbox

For illustrative purposes, consider the following calculation using our default values. When we initialize the input fields with Marked First Capture = 50, Total Captured Second = 60, Recaptured (marked) = 10, the client-side calculator processes the numbers to resolve the formula and produce the final outputs: Population Estimate = 300.

How to Use This Calculator

Set Inputs: Adjust the input values: Marked First Capture, Total Captured Second, Recaptured (marked) to match your scenario.
Verify Outputs: The outputs: Population Estimate are updated in real-time on your screen.
Iterate: Change values and compare alternative scenarios to find your optimal result.
