This learning resource focuses on the mark-recapture technique used in ecology to estimate population sizes of animals. The document outlines the formula for calculation, which includes variables such as total population size (N), number of individuals marked in the first sample (M), total caught in the second sample (C), and the number of marked individuals recaptured (R). Students will engage in practical calculations to estimate populations of squirrels and turtles, while also assessing scenarios that violate key assumptions of the mark-recapture method. The resource encourages analysis of different scenarios, contrasting closed and open populations, and discusses factors that can lead to errors in population estimates. Through vocabulary checks and scenario analyses, students will deepen their understanding of the method and its applications in ecological studies.
