C _rough estimates from experimental data, and experimental estimations of the scale‐of‐choice effect (SCE) for this new estimator, which can be compared with the SCE estimates from Pearson's r

Species	Locality	Pearson's r	All samples		C averaged	SCEC
		SCE5 ®	N	C pooled
Echinolittorina malaccana	Shek O	0.49*	40	0.51	0.32 ± 0.051	0.19**

Littorina fabalis	Abelleira	0.12	95	0.40	0.28 ± 0.044	0.13***

The SCE is experimentally obtained by C _pooled − C _averaged (see Ng et al., 2016; Rolán‐Alvarez et al., 2015).
