“…These sites have nesting and feeding areas of P. chilensis (Hurlbert et al, 1984(Hurlbert et al, , 1986. The zooplankton assemblage in these sites is markedly regulated by salinity level (Hurlbert et al, 1984(Hurlbert et al, , 1986Williams et al, 1995;De los Ríos-Escalante, 2010). The zooplankton assemblage at salinity lower than 5 g/L has copepods such as B. gracilis, Boeckella gracilipes, B. occidentalis, or B. calcaris and cladocerans (Daphnidae and/or Chydoridae), whereas between 5 to 90 g/L the halophilic copepod B. poopoensis is the exclusive component in zooplankton, and at salinity upper than 90 g/L the anostracan Artemia franciscana is the exclusive component (De los Ríos-Escalante, 2010).…”
