Other areas with high selection frequencies overlapped with benthic classes that had targets of 30%.
Subset selection is determined by picking up the most stable voxels, namely, the voxels with highest selection frequency throughout all replications.
The presence of a large number of conservation features surrounding Cape Point and the western Agulhas Bank is likely to explain the higher selection frequency within these areas (Fig 5a).
(d) Record retained genes in the final set of S b. 2. After B iterations, compute the cumulative selection frequency for each gene, F = (F1, F2,..., F P ). 3. Select p genes with the highest selection frequencies.
We did find that the eastern and northwestern parts of our study region also had higher selection frequencies.
This area overlapped with the highest frequency of both upwelling and downwelling eddies and filaments (Fig 3d e) and probably explains why higher selection frequencies resulted (Fig 5a).
Other offshore areas, mainly along the north-western and southern boundary, also had higher selection frequencies, because of the high cost effectiveness of achieving targets in these locations.
When benthic biodiversity was included in the prioritization (Fig 8a,b), there were more areas with higher selection frequencies, indicating less spatial flexibility in the configuration of protected areas (Fig 8c).
We compared the results of scenario one with scenario two that used the average values for the time periods covered by data for chlorophyll a, copepods, anchovies and sardines, there were high correlation of selection frequencies (Spearman's rank correlation of 0.88, p<0.0001) (Fig 5a&c).
