浮游生物是变化的敏感指标，作为海洋食物网的基础，它们支撑着碳固存和渔业生产等重要的生态系统服务。在英国和东北大西洋地区，浮游生物功能群或“生命形式”的变化，根据生物特征构建，是根据海洋战略框架指令（MSFD：2008/56/EC）用于评估远洋栖息地良好环境状况（GES）的正式接受的政策指标。为了确定在英国远洋栖息地的变化，浮游生物的生命形式，从不同的英国数据集收集不同的方法，包括浮游生物采样网，水瓶，集成管采样器，和连续浮游生物记录仪。浮游生物指数方法被用来确定浮游生物生命形式的变化。这是第一次在英国范围内对浮游生物群落进行评估，并构成了英国2020年海洋生物多样性评估的基础。这种方法表明，在过去十年中，评估中使用的一些浮游生物生命形式显示出空间可变的变化。首次使用英国尺度的共同指标评估浮游生物群落变化是朝着评估欧洲海洋GES迈出的重要一步。然而，确定远洋生境的一般环境条件是一个具有挑战性的过程，需要开展更多的工作来解释评估结果，并确定所观察到的变化的原因。
Plankton are sensitive indicators of change and, at the base of marine food webs, they underpin important ecosystem services such as carbon sequestration and fisheries production. In the UK and the Northeast Atlantic region, change in plankton functional groups, or ‘lifeforms’, constructed based on biological traits, is the formally accepted policy indicator used to assess Good Environmental Status (GES) for pelagic habitats under the Marine Strategy Framework Directive (MSFD: 2008/56/EC). To identify changes in UK pelagic habitats, plankton lifeforms, were used from diverse UK data sets collected by different methods, including plankton sampling by nets, water bottles, integrating tube samplers, and the Continuous Plankton Recorder. A Plankton Index approach was used to identify change in plankton lifeforms. This is the first time that the pelagic plankton community has been assessed on a UK-wide scale and forms the foundation of the UK’s 2020 MSFD Assessment for pelagic habitat biodiversity and food webs. This approach revealed that some of the plankton lifeforms used in the assessment displayed spatially-variable changes during the past decade. Assessing plankton community change using a common indicator at the UK scale for the first time is a significant step towards evaluating GES for European seas. Determining GES for pelagic habitats, however, is a challenging process, with additional work required to interpret the assessment results and to identify causation of the changes observed.
