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盐度耐受性和适应盐度降低的能力。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，说明哪些种类的物种(与分类学特征以及生态和功能角色有关)对未来南极沿海生态系统中预测的环境变化越来越不敏感。该项目将主要是试验性的，评估实验室中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、生理和基因组方法来评估对环境侮辱的反应能力。实验将主要在英国南极调查局的冷水海洋水族馆进行，实验对象是经常从南极洲的Rothera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.
