Estimates and standard error (SE) for parametric coefficients in the model of playback experiments in the main survey area

Coefficient	Estimate	Standard error
Intercept (mud to sandy mud)	−5.781	0.792
Sand to muddy sand	0.436	0.022
Coarse‐grained sediment	0.996	0.292
Mixed sediment	1.111	0.026
Till, boulders and bedrock	1.001	0.038

The parametric coefficients relate to the sediment type factor covariate. All coefficients have p < 2E‐13 in a z‐test of the null hypothesis that the coefficient is zero.
