This activity addresses how predation may affect the frequency of two color morphs in a population. Students collect and analyze data from clay salamander models ('claymanders') to determine whether there is a difference in predation rates.

Students will set up transects with clay models of the two color morphs (striped, lead) and monitor them daily to record predation events over the course of two weeks. The goal of the study is to test whether the two morphs experience differential ‘survival’ as a result of predation. Data will be aggregated and analyzed across all transects. Discussion of the data should also address experimental design and any issues that may have arose during data collection.
