“…This indicates local fishery as a significant source of items, a pattern that has been previously reported in oceanic islands and also on undeveloped continental beaches (Ribic et al, 2012;Eriksson et al, 2013;Lavers and Bond, 2017). In the SBR, the fishery has been recognized as a traditional and intense activity (CCO, 2015;Gavio et al, 2015), and it might also be a significant source of plastics and microplastics to the atoll and beaches.…”

The Albuquerque atoll was studied as a representative natural laboratory to explore the role of sea-based sources of marine litter. This work aimed to identify the small-scale spatial distribution of marine litter (i.e., plastic, glass, paper, and others) as well as to explore the connectivity among the atoll habitats (sand beach, water surface, and reef) to give insights of potential sources of marine litter (> 5 cm), mainly plastics. Marine litter was dominated by plastic items, as expected, with an average value of 0.5 items/m 2 . Large microplastics (1-5 mm) were also sampled on beaches with an average value of 90 particles/m 2 . In the atoll inner lagoon, marine litter was also composed by plastic, mainly fragments (average 0.059 items/m 3 ). The predominance of plastic fragments on both the sea surface and beaches of the atoll makes inferences on sources limited. However, o fishing activities and sea-based sources might be relevant since local sources are very limited.

“…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.

“…Notes: the genus Dasya C. Agardh includes red algae with a hairy and delicate appearance and rigid to flaccid Gavio, 2012) and D. rigidula (Gavio et al, 2015). The taxonomy of Dasya is very difficult, and its diversity is still far from being satisfactorily understood.…”

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.
