Results of linear mixed effect models examining factors affecting whole-animal metabolic rate (log()) under heatwave and predator-prey interactions for fathead minnow (<i>Pimephales promelas</i>), largemouth bass (<i>Micropterus salmoides</i>), and walleye (<i>Sander vitreus</i>).

Related to Fig 3.3-3.4, time represents different measurement periods, including resting metabolic rate (RMR), 1 h heatwave at 30°C (heatwave), 1 h post heatwave (post-heatwave), and first 1h of predator-prey interaction (interaction). Models include fish ID as a random factor. Marginal r2 = 0.60, 0.54, 0.82, and 0.82, while conditional r2 = 0.79, 0.77, 0.84, and 0.82 for fathead minnow with largemouth bass predator, fathead minnow with walleye predator, largemouth bass with fathead minnow prey, and walleye with fathead minnow prey, respectively. Significant factors are shown in bold.
