“…Independencia Bay is an area influenced by strong winds and currents, upwelling cycles (Quispe et al, 2010;Tarazona et al, 1991;Taylor et al, 2008) and also by the addition of organic matter and shells of the scallop Argopecten purpuratus, which increases its population size during EN events (Mendo et al, 1987;Tarazona et al, 2007;Taylor et al, 2008;Wolff and Mendo, 2000). Thus, the area is controlled mainly by physical forces (Tarazona et al, 1991).…”
