a, Open circles represent counts for individual plots and lines connect the same plots through time. Solid circles and vertical line segments represent the estimated mean and 95% CI for each sampling event. There was a small but significantly greater change in density of shore crab in No Otter plots compared to Otter plots when accounting for time (P = 0.047). b,c, Smoothers for day since start (b) and month used in the GAMM (c). Note: Final shore crab densities were analysed in December 2016 (see Extended Data Fig. 1a).
