“…Recent results, obtained by expeditions [52] and independent research, carried out in the Seaflower Reserve of the Caribbean Sea, contributed to the identification, and listing of new marine algae (i.e., micro-, macroalgae, and cyanobacteria) for Colombia [53][54][55][56][57][58][59].…”

Colombia has a diverse range of marine ecosystems in the coastal and insular areas of the Caribbean Sea and the Pacific Ocean. Seaweed research has focused mainly on the identification and taxonomic distribution of 628 species identified so far, mainly in the Caribbean Sea. Among the most widely cultivated genera of seaweeds in open-sea pilot systems in Colombia are Hydropuntia, Gracilaria, Hypnea, Kappaphycus, and Eucheuma. These genera have shown low yields as a consequence of high tissue fragility, epiphytism, sedimentation, and nitrogen deficiency. In addition, the evaluation of the biological activity of selected seaweed compounds has advanced considerably, focusing on their composition and their use for direct consumption by humans and animals. Despite the diversity of seaweeds, as well as certain technical and scientific advances, Colombia is still lagging behind other countries in seaweed exploitation, both in Latin America and worldwide. This current status raises the need to increase research, technological (agro-tech) appropriation, and the adoption of effective public policies that will boost algal businesses. In addition, seaweed cultivation could support the current blue economy transition in Colombia, which could eventually allow the country to enter the global seaweed market.

“…Despite the great biodiversity and the conservation priorities of the International Reserve, not all groups of organisms have received the same attention, from a research point of view. Until the past decade, seaweeds were one of the least studied taxa (Albis-Salas and Gavio, 2011); recently some research has focused on macroalgal diversity of the Archipelago, and started to reveal a flora much more diverse than previously appreciated (Albis-Salas and Gavio, 2011Ortiz and Gavio, 2012;Reyes-Gómez et al, 2013;Vega-Sequeda et al, 2015;Barrera et al, 2016;Rincón-Díaz et al, 2014Reyes-Gómez and Gavio, 2017). From these studies, the macroalgal diversity passed from 202 species registered in 2003 (Díaz-Pulido and Díaz-Ruíz, 2003) to the actual 314 taxa, including 28 Cyanophyceae, 41 Phaeophyceae, 103 Clorophyta and 142 Rhodophyta, the latter group being the most diverse (Rincón- Díaz and Ramos-Gallego, 2016;Rincón-Díaz et al, 2018).…”

Background and Aims: During the past decade, phycological research in the Seaflower International Biosphere Reserve has revealed a much more diverse marine flora than historically appreciated. This work aims to contribute to the knowledge of macroalgal biodiversity in the Archipelago of San Andres, Old Providence and Saint Cataline, Colombian Caribbean, adding 11 new records of red algae. Methods: The samples were collected around the islands in ten points covering different ecosystems, by SCUBA diving at depths between 0 and 37 m. Sampling was carried out between August and November 2009, December 2012, and September 2019 during the Seaflower Scientific Expedition. The algae collected were preserved in a 4% formalin/seawater solution. The identification was carried out using an optical microscope and specialized literature. All specimens were deposited in the herbarium JIW of the Biology Department of the Universidad Nacional de Colombia, Bogotá, Colombia. Key results: Eleven species of red macroalgae are newly reported for the Seaflower International Biosphere Reserve in the Caribbean Sea. Of these taxa, six have been previously reported for the Colombian Caribbean: Botryocladia spinulifera, Champia taironensis, Dasya caraibica, Pterocladiella bartlettii, Seirospora occidentalis, Spyridia aculeata subsp. complanata. The remaining five species are new records for the country: Botryocladia cf. bahamensis, Botryocladia cf. bermudana, Ceramium brevizonatum var. caraibicum Gloioderma iyoense and Wrightiella tumanowiczii. With these results the International Biosphere Reserve Seaflower hosts 153 species of Rhodophyta, belonging to 12 orders, 27 families and 73 genera. Conclusions: With the research carried out in the last 10 years, the number of registered taxa has increased from 202 to 325, which represents a 62% increase in the knowledge of macroalgae diversity and places the Archipelago in the second most diverse region in the Colombian Caribbean.

Biodiversity of benthic filamentous cyanobacteria in tropical marine environments of Bahia State, Northeastern Brazil

This study aimed to better understand the biodiversity and ecological aspects of benthic filamentous cyanobacteria along the coast of an extensive Brazilian tropical region with underestimated biodiversity. We collected samples between 2010 and 2012 in 24 areas along the coast of the State of Bahia, Northeastern Brazil. We analyzed biodiversity, life form, and spatial distribution of filamentous cyanobacteria on various marine substrata. The intertidal area was divided into three microhabitats according to hydrodynamics: tidal pools, protected reef region, and front reef region. Thirty-two taxa were identified and Oscillatoriales showed the highest biodiversity (16 taxa), followed by Nostocales (9), Synechoccocales (5) and Spirulinales (2). We reported 22 new references to Bahia State. Twenty-two taxa occurred only in one beach, and Symploca cf. hydnoides Gomont was the only widely distributed along the coast of Bahia. Epilithic (21 taxa) and epiphytic (15) showed the greatest species richness. Only two species presented epizoic life form. We observed the highest species richness in the protected reef region (17 taxa). We found eleven and eight taxa in the tidal pool and supralittoral zone, respectively. No cyanobacteria were found in the front reef region, an area with high hydrodynamics. This research presented many taxa in common with previous studies on cyanobacterial diversity developed in other tropical regions around the globe. The great biodiversity and new records reported in this study highlight the need of further surveys in tropical coastal environments, areas still underexplored in terms of biodiversity of cyanobacteria.
