本文报道了在乌拉圭海岸首次发现褐藻myriogloea majorAsensi （Chordariacea, Phaeophyceae）和绿藻gayralia oxysperma(k<s:1> tzing) K.L. Vinogradova ex Scagel等（Ulvophyceae，绿藻门）。这些新记录可能分别代表一个向北和向南的范围扩展形式。majorandG。产于大西洋西南部。这些发现特别相关，因为乌拉圭海岸被强调为南大西洋关于大型藻类多样性研究最少的地区之一，尽管它的植物地理相关性是相邻生物地理省之间的过渡带。需要对乌拉圭海岸的海藻多样性和分布进行进一步的研究，以便更新海洋植藻植物的清单。分子方法应该是强制性的，因为已经报道了该地区存在一些隐种，如肉豆杉和gayralia。考虑到该地区的生物地理相关性，以及将这些新记录与区域环流格局变化、全球海洋气象变化和/或人为引入联系起来的迫切需要，这些新事件突出了在该地区进行紧急抽样调查的必要性。
This study reports the first occurrences of the brown seaweedMyriogloea majorAsensi (Chordariacea, Phaeophyceae) and the green seaweedGayralia oxysperma(Kützing) K.L. Vinogradova ex Scagel et al. (Ulvophyceae, Chlorophyta) along the Uruguayan coast. These new records could represent respectively a northward and southward range extension forM. majorandG. oxyspermain the Southwestern Atlantic. These findings are particularly relevant since the Uruguayan coast has been highlighted as one of the least studied areas in the Southern Atlantic concerning macroalgal diversity, despite its phytogeographic relevance as an ecotone between the adjacent biogeographic provinces. Further research regarding seaweed diversity and distribution in the Uruguayan coast is demanded, in order to update the list of the marine phycoflora. Molecular approaches should be mandatory, since the presence of several cryptic species, such asMyriogloeaandGayralia, in the area has been reported. Considering the biogeographic relevance of the area, and the pressing needs to relate these new records with changes in regional circulation patterns, global meteoceanographic changes and/or anthropic introductions, these new occurrences highlights the need for urgent sampling surveys in the area.
