AGUILAR-ROSAS, Luis E.; MIN BOO, Sung; MI KIM, Kyeong  e  AGUILAR-ROSAS, Cristiane V.. First record of the Japanese species Grateloupia turuturu(Halymeniaceae, Rhodophyta) in the Mexican Pacific coast. Hidrobiológica [online]. 2012, vol.22, n.2, pp.189-194. ISSN 0188-8897.

Floristic surveys were conducted in November 2008, in which we collected specimens of Grateloupia turuturu, growing attached to different substrata in Ensenada Port, Baja California, México. From this finding, monthly observations were performed until July 2010 to find a possible displacement. Populations with specimen's average length of 40 cm were commonly found in the harbor. On the basis of morphological and molecular analyses of plastid rbcL gene sequences, we confirmed the taxonomic identity of G. turuturu. We present the first record of G. turuturu as introduced species in the Mexican Pacific coast. Considering this new finding in México, we conclude that the colonization by this species in the Pacific coast has started, and hence its geographical range of distribution is increasing. Likewise, we found Grateloupia californica, and it is discuss its presences on Baja California coast.
