我们对圣劳伦斯湾和斯科舍陆架地区重要海洋物种的温度、盐度、pH、深度和氧偏好和阈值进行了文献综述。我们将54种已确定的鱼类和大型无脊椎动物分类为重要，因为它们支持商业渔业，已受到威胁或处于危险状态，或满足以下标准之一：副渔获物，诱饵鱼，入侵，流浪，对生态系统能量转移重要，或上述物种的捕食者或猎物。根据对未来海洋物理和生物地球化学条件的预测，汇编的数据可以评估物种一级的影响，包括生理压力和死亡率。如果在苏格兰中部大陆架上观测到的多年代代性氧气趋势继续下去，在未来的半个世纪里，许多物种将失去有利的氧气条件，经历氧气压力，或因氧气不足而消失。预估的区域趋势和自然变率都很大，而自然变率将交替放大和抑制人为变化。如果将变异估计包括在趋势中，物种会提前几十年遇到不利的氧气条件。最后，在苏格兰中部大陆架高分辨率海洋模型的潜在未来情景背景下，评估了成年大西洋狼鱼（Anarhichas lupus）和成年大西洋鳕鱼（Gadus morhua）的温度和氧气阈值。
We conducted a literature review of reported temperature, salinity, pH, depth and oxygen preferences and thresholds of important marine species found in the Gulf of St. Lawrence and Scotian Shelf region. We classified 54 identified fishes and macroinvertebrates as important either because they support a commercial fishery, have threatened or at risk status, or meet one of the following criteria: bycatch, baitfish, invasive, vagrant, important for ecosystem energy transfer, or predators or prey of the above species. The compiled data allow an assessment of species-level impacts including physiological stress and mortality given predictions of future ocean physical and biogeochemical conditions. If an observed, multi-decadal oxygen trend on the central Scotian Shelf continues, a number of species will lose favorable oxygen conditions, experience oxygen-stress, or disappear due to insufficient oxygen in the coming half-century. Projected regional trends and natural variability are both large, and natural variability will act to alternately amplify and dampen anthropogenic changes. When estimates of variability are included with the trend, species encounter unfavourable oxygen conditions decades sooner. Finally, temperature and oxygen thresholds of adult Atlantic wolffish (Anarhichas lupus) and adult Atlantic cod (Gadus morhua) are assessed in the context of a potential future scenario derived from high-resolution ocean models for the central Scotian Shelf.
