a Cluster and b NMDS analyses of the abundance of copepod species recorded during the study period in the Taperaçu estuary, northern Brazil. c Relative contributions of the dominant species to total copepod abundance. Dominance of oligomesohaline species (group I); dominance of marine species (group II). The main groups shown in the Cluster and NMDS (stress: 0.03) are separated by dashed lines at a similarity level of 60 %
