Table 1 Statistical models examining the effects of Temperature (MHW magnitude) and Period (heatwave or recovery) on the proportion of individuals to perform (generalised linear mixed-effects model) and time taken to (cox mixed-effects model): (A) emerge from shell, (B) attempt to right, and (C) successfully right. Bold text indicates statistical significance of terms.
From: Marine heatwaves of different magnitudes have contrasting effects on herbivore behaviour
