Fig. 3: Estimates of predator/scavenger activity during each of the five experimental trials.

The total number of individual crabs (Carcinus meanas and Cancer irroratus) (top panel), the total number of mesocosm plots containing omnivorous mudsnails (Ilyanassa obsoleta) (middle panel), and the overall predator activity index (crabs + mudsnail plots; bottom panel) observed across all mesocosm plots (n = 30) in each of the five trials. Colours denote a gradient from lowest (gray) to highest (red) mean air temperature during fishing. See Supplementary Data 4 for source data.
