In the biplot diagrams, the species are grouped into the IUCN categories (CR = Critically Endangered; EN = Endangered; VU = Vulnerable; NT = Near Threatened; LC = Least Concern; DD = Data Deficient). Arrows indicate the correlations among variables: a longer arrow indicates that the corresponding variable is more important; a small angle between two arrows indicates that the correlation between the two variables is high. The first axis explained most of the variability (p = 0.001). Red circles indicate catches in PPAs black circles catches in UPAs. Significant predictors are identified with a * (p = <0.001). sst = sea surface temperature; dox = dissolved oxygen; pho = phosphate; Hum. Imp = human impacts.
