Average values of total abundance and alpha diversity of zooplankton in the Caucahué Channel, obtained for significantly different northern and southern groupings. a Total abundance (Ind 100 m−3), b Species richness, c Simpson dominance, d Pielou Evenness, e Shannon–Wiener diversity. Bars represent standard deviation. NS: Northern surface layer, SS: Southern surface layer, NB: Northern deeper layer, and SB: Southern deeper layer
