Climate change (CC) and ocean acidification (OA) are considered some of the major potential drivers of changes in marine ecosystems, affecting human wellbeing through changes in ecosystem services such as fisheries. To develop effective marine conservation and management policies under CC and OA, there is an urgent need to identify ecosystems and their components that are most vulnerable to such impacts, and develop scientifically robust scenarios of future changes. Recently, there have been major advances in establishing fundamental theories to explain biological responses to CC and OA, and development of modelling tools to simulate these biological responses. However, so far, these efforts focus on CC and OA effects at the organismal and population levels, while there is a large gap in our understanding of biological responses at community and ecosystem levels. This leads to two lines of research questions:

气候变化和海洋酸化被认为是海洋生态系统变化的一些主要潜在驱动因素，通过渔业等生态系统服务的变化影响人类福祉。为了根据《气候变化框架公约》和《海洋行动计划》制定有效的海洋养护和管理政策，迫切需要确定最容易受到这种影响的生态系统及其组成部分，并为未来的变化制定科学可靠的设想。最近，在建立解释CC和OA的生物学反应的基本理论以及开发模拟这些生物学反应的建模工具方面取得了重大进展。然而，到目前为止，这些努力主要集中在生物和种群层面的CC和OA效应上，而我们对社区和生态系统层面的生物反应的理解存在很大差距。这就引出了两个研究问题：
