Description
This QUBES lesson takes a look at the effects of lower pH on predator-prey interactions, precisely flight responses and interactions between intertidal invertebrates (snails and sea star predators) using the variables of pH, the proportion of time out of water as the flight response, and the presence or absence of predator cue. This lesson connects to the bigger picture of ocean acidification and dangers by discussing how changes in snail behavior could influence general trophic interactions and, consequently, ecosystem functioning.
This lesson also contains introductory information on GLMs using the proportion and pH data provided from the focal paper. Students also learn how to visualize these variables in the R programming language.
