Molecular evidence of the presence of Dictyota dichotoma in Argentina based on sequences from mtDNA and cpDNA and a discussion of its possible origin
Dictyota is a brown alga genus inhabiting tropical to warm temperate environments where it performs an important ecological role, such as a food source, shelter and substrate to several species of invertebrates and other algae. The taxonomy of this genus is troublesome, with poor species delimitatio...

Dictyota is a brown alga genus inhabiting tropical to warm temperate environments where it performs an important ecological role, such as a food source, shelter and substrate to several species of invertebrates and other algae. The taxonomy of this genus is troublesome, with poor species delimitation and doubtful records in the literature. Dictyota dichotoma, the type speciesof the genus, was commonly accepted as a cosmopolitan species because of the inaccurate geographical distribution range as a consequence of its misidentification in several parts of the world. Recent studies with molecular data revealed new species and a new understanding of the evolution and biogeography of the genus Dictyota. These studies confined populations of D.dichotoma to Europe (Atlantic and Mediterranean coasts) and the Macaronesian Islands (Azores, Madeira and Canary archipelagos). Also, they confirmed its presence in South Africa, but, whether the species was native or introduced in South Africa could not be verified. In the present study two regions of cpDNA (psbA, rbcL) and one region of mtDNA (nad1) from Argentine samples, identified morphologically as D. dichotoma, were analyzed and compared with other Dictyota species. The identity of these samples as D. dichotoma was confirmed. A haplotype network analysis using all available psbA sequences distinguished seven haplotypes divided into two geographic groups: Atlantic-Mediterranean and Canarian.
