Resistance of Antarctic marine species to predicted freshening and lower salinity in the Southern Ocean

该项目将评估一系列南极海洋无脊椎动物的耐盐性和适应低盐度的能力。它还将评估多种压力因素（至少是温度升高和盐度降低）的影响。其目的是提供一套更好的预测，预测南极沿海生态系统中哪些类型的物种（与分类特性、生态和功能角色有关）对未来预测的环境变化的抵抗力更强或更弱。该项目将主要是实验性的，在实验室评估物种对生存极限和亚致死反应的耐受性。这将涉及使用形态学、生理学和基因组学方法来评估应对环境损害的能力。实验将主要在英国南极调查局的冷水海洋水族馆进行，实验对象是定期从南极罗瑟拉站返回英国的动物。

The project will assess the salinity tolerances and ability to acclimatise to lowered salinity in a range of Antarctic marine invertebrates. It will also assess the impacts of multiple stressors (at least elevated temperature and lowered salinity). The aim is to provide a much better set of predictions about what types of species (in relation to taxonomic identities and ecological and functional roles) are more and less resistant to future predicted environmental changes in Antarctic coastal ecosystems. The project will be primarily experimental assessing tolerances of species in the laboratory to both survival limits and sublethal responses. This will involve the use of morphological, physiological and genomic methods to evaluate capacities to respond to the environmental insult. Experiments will primarily be set in the cold-water marine aquarium in the British Antarctic Survey on animals routinely returned to UK from their Rothera station in Antarctica.
