BACKGROUND The Azores are oceanic islands located in the Northern Atlantic Ocean and are particularly rich in aquatic systems, ranging from freshwater, brackish, marine and thermal habitats. Due to the increase in local anthropogenic pressures and global warming, several azorean lakes began to reveal signs of eutrophication that led to the implementation of monitoring programmes and management strategies on the most impacted lakes. Later, the Water Framework Directive (2000/60/EC) demanded the establishment of biomonitoring programmes for European freshwater ecosystems and the limited Azorean monitoring programmes were extended to a larger set of lakes. Since the establishment of the aquatic systems monitoring programme in the Azores archipelago, lakes have been regularly sampled, producing innumerous unpublished records of cyanobacteria that are difficult to access. NEW INFORMATION Here we present the occurrences of cyanobacteria in Azorean lakes that result from 22 years of phytoplankton monitoring in a total of 1948 cyanobacteria occurrences from 968 phytoplankton sampling events on Azorean lakes done between 1996 and 2018 as part of regional inland aquatic ecosystems monitoring programmes. Forty two cyanobacteria taxa were identified in those events, 28 species and 14 at genus level. This information is crucial for conservation, biodiversity studies and lake management, as some of the cyanobacteria species present are bloom-forming and have the ability to produce toxins. This will also allow for the identification of invasive species and possible targeted control and mitigation programmes, according to the species present in the Azorean lakes.

葡萄牙亚速尔群岛淡水湖中的蓝藻：长期浮游植物监测数据。

背景技术亚速尔群岛是位于北大西洋的海洋岛屿，水生系统特别丰富，包括淡水、微咸水、海洋和热栖息地。由于当地人为压力的增加和全球变暖，几个亚速尔群岛湖泊开始出现富营养化迹象，导致对受影响最严重的湖泊实施监测计划和管理策略。后来，水框架指令 (2000/60/EC) 要求为欧洲淡水生态系统建立生物监测计划，并将有限的亚速尔群岛监测计划扩展到更多的湖泊。自亚速尔群岛水生系统监测计划建立以来，定期对湖泊进行采样，产生无数难以获得的未发表的蓝藻记录。新信息 在这里，我们展示了亚速尔群岛湖泊中蓝藻的出现，这些蓝藻是在 1996 年至 2018 年间作为区域内陆水生生态系统监测计划的一部分在亚速尔群岛湖泊上进行的 968 次浮游植物采样事件中进行的 22 年浮游植物监测中产生的，共有 1948 次蓝藻出现。在这些事件中鉴定出 42 个蓝藻类群，其中 28 个物种和 14 个属水平。这些信息对于保护、生物多样性研究和湖泊管理至关重要，因为存在的一些蓝藻物种正在形成水华并具有产生毒素的能力。这也将有助于识别入侵物种和可能的有针对性的控制和缓解方案，
