Extended Data Fig. 6: Spatial distributions of the P. borealis, S. canicula and S. plicata compared with the Metabolic Index, temperature and \({{\boldsymbol{p}}}_{{{\rm{O}}}_{2}}\).
a–i, Spatial distributions of the species shown in Fig. 2 (P. borealis, S. canicula and S. plicata) were compared with the Metabolic Index (a, d, g), temperature (b, e, h) and \({p}_{{{\rm{O}}}_{2}}\) (c, f, i). a–c, P. borealis. d–f, S. canicula. g–i, S. plicata. A single lower limit of Φ bounding each species range is contoured (Φcrit; black lines). For all species, Φcrit more skilfully categorizes occupied habitat than either temperature limits or lower \({p}_{{{\rm{O}}}_{2}}\) considered individually. This skill is shown by the higher ratio of F1-scores of Φ relative to temperature or to \({p}_{{{\rm{O}}}_{2}}\) (in parentheses, respectively) from the full four-dimensional species distribution. Occurrence data for each species are shown (blue dots). Regions for zonal averaging are as in Fig. 2.
