ALBIS-SALAS, Margarita Rosa  and  GAVIO, Brigitte. NOTES ON THE MARINE ALGAE OF THE INTERNATIONAL BIOSPHERE RESERVE SEAFLOWER, CARIBBEAN COLOMBIA IV: NEW RECORDS OF MACROALGAL EPIPHYTES ON THE SEAGRASS THALASSIA TESTUDINUM. Bol. Invest. Mar. Cost. [online]. 2015, vol.44, n.1, pp.55-70. ISSN 0122-9761.

Nine species of macroalgae are newly reported for the Caribbean International Biosphere Reserve Seaflower. Of these taxa, Neosiphonia sphaerocarpa, Polysiphonia schneideri, Polysiphonia sertularioides, Cladosiphon occidentalis, and Phaeophila dendroides, have been previously reported from Colombian waters, whereas Ulothrix sp., Ulva flexuosa subsp. paradoxa, Chaetomorpha minima, and Cladophora liniformis represent new records for the country. All the algae were found growing epiphytically on Thalassia testudinum in shallow (<1 m) seagrass meadows around San Andrés Island. Their morphological features are discussed.

Keywords : Colombia; Epiphyte; Marine algae; New records; Polysiphonia.
