Extended Data Fig. 7

The F1-score measures the ability of each environmental variable at a given threshold value to categorize the ocean into inhabited and uninhabited regions. The maximum F1-score for Φ is then compared with the maximum value for temperature or \({p}_{{{\rm{O}}}_{2}}\) thresholds and plotted on a log10 scale such that positive (negative) values indicate a stronger (weaker) predictive skill for Φ. Printed numbers (n) on the graph indicate the number of species that fall within each quadrant (for numbers in quadrants) or to each side of the axes (for numbers on axes). For example, Φ outperforms T in 44 species, and underperforms in only 4, and outperforms both T and \({p}_{{{\rm{O}}}_{2}}\) in 30 species. A maximum F1-score was found for 48 species, while 8 additional species had no clear maximum in F1-score.
