Heatmap of the square-root transformed abundances (ind. m⁻²) for taxa accounting for > 3% of the copepod and diplostracan total abundance in 2019. The colors indicate abundance values (ind m⁻²). The colored bars indicate groups of stations (Groups) identified by cluster analysis (Fig. S6), the bathymetric strata (1,2, and 3), and the distinct upwelling latitudinal Zones (A, B, C, D). Copepod and diplostracan are clustered (group average) based on the Bray–Curtis distance matrix of their relative abundance. Bold font refers to taxa contributing to 70% similarity described in the SIMPER Table S6. Numbers along the bottom of the heatmap correspond to the station number as shown in Figs S1 and S6.
