As in all oceans, plankton communities of SPSG are also threatened by ocean acidification (Doney et al., 2012), which may specifically affect gyre plankton communities since gyre species may have less preadaptation to fluctuations in ocean pH compared to coastal species (Beaufort et al., 2011; Kelly & Hofmann, 2013).

It is widely believed that cell exposure to mild stress results in the acquisition of cellular resistance to further lethal stress, what is called "adaptive response" or "preadaptation" [6,7].

Ricciardi and Mottiar (2006) indicated that Darwin's naturalized hypothesis has rarely been tested statistically and results thus far have been equivocal; some studies support this hypothesis as the one of Rejmaneck (1996), while others reject it and, in some cases support the preadaptation hypothesis (Duncan and Williams, 2002).
