摘要

背景和目的:大型藻类是海洋生态系统的主要生产者,因此,有关其物种组成和分布的信息对于制定保护战略和可持续利用其栖息的沿海海岸线是非常必要的。然而,在哥伦比亚的不同海洋区域,如莫罗斯基略湾,这方面的知识却很匮乏,需要加大采样力度并不断更新数据。因此,这项工作旨在根据已发表和未发表的生物记录以及最近的取样,提供上述地区大型藻类的最新清单。方法:从 1976 年至今的历史记录中整理出文献信息,并在莫罗斯基略湾的一个地点进行采样补充。根据最新的命名法对分类群进行了整理和更新,并使用切尼指数确定了藻类植物群的地理亲缘关系:出现的 97 个分类群分为 3 类、15 目、32 科和 54 属。根据切尼指数,该地区的植物区系属于混合型。海湾地区报告了 6 个附有注释和插图的新记录:结论:对评估区域的大型藻类清单进行了更新,显示出采样区域更清晰的历史全景,这表明未来发现新记录的潜力非凡,将增加对哥伦比亚加勒比海植物区系的了解,特别是因为没有关于红藻、附生和附生物种的记录。

Listado actualizado y nuevos registros de macroalgas para el Golfo de Morrosquillo, Caribe colombiano
Background and Aims: Macroalgae are primary producers of marine ecosystems, so the information regarding their species composition and distribution is necessary to develop conservation strategies and sustainable use of the coastal coastlines they inhabit. However, in different marine regions of Colombia, such as the Gulf of Morrosquillo, this knowledge is scarce, requiring a greater sampling effort and constant updating of data. Therefore, this work aims to provide an updated list of the macroalgae in the aforementioned region, based on published and unpublished biological records and recent sampling. Methods: Bibliographic information was compiled from historical records from 1976 to the present and complemented with sampling in one location in the Gulf of Morrosquillo. The taxa were organized and updated based on the most recent nomenclature, and the geographical affinity of the algal flora was determined using the Cheney index.Key results: The occurrence of 97 taxa classified in three classes, 15 orders, 32 families and 54 genera. Red algae, with 48 taxa, were the group that contributed the largest number of species, and the phycoflora of the region was of a mixed type according to the Cheney index. Six new annotated and illustrated records were reported for the Gulf: Antithamnionella breviramosa, Centroceras gasparrinii, Bostrychia tenella, Melanothamnus sphaerocarpus, Agardhiella ramosissima and Feldmannia mitchelliae.Conclusions: The inventory of macroalgae in the evaluated region was updated, showing a clearer historical panorama of the sampled areas, which suggests an extraordinary potential in the future discovery of new records that would increase the knowledge about the phycoflora of the Colombian Caribbean, particularly because the records of encrusting red algae, epiphytic and epizoic species are non-existent.
