Description

This module is designed for locations where students can visit salamander mark-recapture sites. Students are provided with capture history data for two sampling occasions. In the field, students collect the third recapture sample (scoring the individual mark or recording the individual as new). For the analysis portion, students learn the difference between the Peterson method and the Schnabel method for estimating population size from mark-recapture data. This lab took two periods, one for field data collection and one for the data analysis.
