The Kerguelen Islands (49°26’S, 69°50’E) represent a unique environment due to their geographical isolation, which protects them from anthropogenic pollution. The ability of the endemic mussel, part of the Mytilus complex, to cope with moderate heat stress was explored using omic tools. Transcripts involved in six major metabolic functions were selected and the qRT-PCR data indicated mainly changes in aerobic and anaerobic energy metabolism and stress response. Proteomic comparisons revealed a typical stress response pattern with cytoskeleton modifications and elements suggesting increased energy metabolism. Results also suggest conservation of protein homeostasis by the long-lasting presence of HSP while a general decrease in transcription is observed. The overall findings are consistent with an adaptive response to moderate stresses in mussels in good physiological condition, i.e. living in a low-impact site, and with the literature concerning this model species. Therefore, local blue mussels could be advantageously integrated into biomonitoring strategies, especially in the context of Global Change.

凯尔盖朗群岛 (49°26'S, 69°50'E) 由于地理上的孤立，代表了一个独特的环境，保护它们免受人为污染。地方性贻贝的能力，将一部分紫复杂的，以应对适度的热应激使用组学工具进行了探索。选择涉及六种主要代谢功能的转录本，qRT-PCR 数据主要表明有氧和无氧能量代谢和应激反应的变化。蛋白质组学比较揭示了典型的应激反应模式，细胞骨架修饰和元素表明能量代谢增加。结果还表明，HSP 的长期存在可以保护蛋白质稳态，同时观察到转录的普遍减少。总体发现与处于良好生理状态（即生活在低影响地点）的贻贝对中等压力的适应性反应以及有关该模型物种的文献一致。所以，
