  1. SST max. = maximum monthly sea surface temperature (SST), Chlorophyll a max. = maximum monthly near-surface chlorophyll a concentration (set to a maximum of 10 mg/m3), SSS average = annual average sea surface salinity (SSS, set to a minimum of 30 PSU), PAR max. = maximum monthly photosynthetically active radiation reaching the ocean surface (PAR), SST range = annual SST range, pH average = annual average pH. Highest Jackknife scores represent largest contributions of environmental variables to explaining geographic distributions of morphotypes, but do not provide information on values of selected environmental variables.
