Abstract

ESPINOZA-AVALOS, Julio et al. Presence of Caulerpaceae (Chlorophyta) in the Yucatan Peninsula, Mexico. Bot. sci [online]. 2015, vol.93, n.4, pp.845-854. ISSN 2007-4476.  https://doi.org/10.17129/botsci.160.

Twenty-three taxa of Caulerpaceae (14 species, 3 varieties, and 6 forms) were found in 70 sites along the coast of the Yucatan peninsula, Mexico. The invasive macroalgae C. brachypus f. parvifolia is reported for the first time in Quintana Roo, Mexico. A hierarchical agglomerative clustering analysis showed the nonexistence of sites grouping at both sides of the Yucatan peninsula, in contrast with other studies that have reported differences at both sides of the peninsula based on the presence of other groups of the marine biota. Caulerpa cupressoides, C. prolifera, and C. verticillata were the species having more records (in 30, 23, and 21 sites, respectively), while C. brachypus, C. lanuginosa, C. microphysa, and C. webbiana were among the less common species, with one record each species.

Keywords : Caulerpa; Gulf of Mexico; Mexican Caribbean; invasive macroalgae; Quintana Roo.
