Spatial and temporal distribution in density and biomass of two Pseudodiaptomus species (Copepoda: Calanoida) in the Caeté river estuary (Amazon region - North of Brazil)
Spatial and temporal density Makeup Brushes and biomass distribution of the planktonic copepods Pseudodiaptomus richardi and P.acutus along a salinity gradient were investigated in the Caeté River Estuary (North-Brazil) in June and December, 1998 (dry season) and in February and May, 1999 (rainy season).Copepod biomass was estimated using regressi
