Overview: This lesson centers around the marginal value theorem (MVT, Charnov 1976), which describes how animals should forage in patches. The students will complete a lesson in R to practice using data they will collect directly as they ‘forage’ in an in-class lab. Specifically, they will practice creating vectors and tables of data to use in plotting and creating an ANOVA to compare high-, medium-, and low-density patches by their associated giving-up time (GUT) data. Students are then expected to repeat the coding steps they learned in R with example data to later test a hypothesis of their own.
- Complete a prelab reading to familiarize themselves with the goals of the lesson and the background ecological information of optimal foraging
- Practice coding elements necessary to create data frames, plot, and test MVT hypotheses based on the data
- Apply the coding learned through swirl to their own hypothesis to answer whether different density patches lead to different GUTs
