Conditional effects and 95% CI of a two-way interaction between treatment and number of days since tagging on sea star feeding rate. Day 0 = day of tagging, preceded by 2 weeks of acclimatisation. Dashed lines mark the start (day 0) and the end of the farmed mussel diet (day 40). The superimposed boxplot is the number of mussels per individual per day for each treatment at each time step. The horizontal line indicates the median, lower, and upper hinges corresponding to the first and third quartiles (the 25th and 75th percentiles). Whiskers extend from the hinge to no further than 1.5 × the inter-quartile range
