Contribution of environmental variables to the Ecological Niche Model of each species. Sea surface temperature (SST) derivatives were the most important variables, followed by diffuse attenuation (DA), salinity, and surface air temperature (SAT) derivatives

Variable	Derivative	Unit	Contribution (%)
			Fucus serratus	Fucus vesiculosus	Ascophyllum nodosum
SST	Minimum	°C	66	46.4	82.3
SST	Maximum	°C	24.7	42.8
SST	Mean	°C	9.3
SAT	Minimum	°C			7.3
Salinity	Mean	PSS			10.4
DA	Minimum	m−1		10.8
