海洋物种活动范围随气候变化而发生的变化往往被归因于海洋变暖导致的氧气限制。在这里,我们报告独特的代谢温度敏感性的无数垂直迁移的海洋物种,每天交叉深度相关的温度和氧气梯度。在这些类群中,选择有利于高代谢活动的捕食者-猎物的相互作用,在温暖的浅水和缺氧的耐受性,在寒冷的深度。这些不同的选择性压力导致氧供应能力的热不敏感性和活性代谢率的热敏感性增强。有氧范围是减少在寒冷,远远超出热力学的影响,无论环境中的氧气水平,解释了本地分布的热带移民和他们最近的范围扩大后,变暖事件。寒冷的沃茨目前构成了一个充满活力的障碍,纬度范围扩大的垂直迁移。随着气候变化导致的变暖接近并最终超过过去变暖事件中的温度,这一能量障碍将得到缓解。
Alterations of marine species’ ranges with climate change are often attributed to oxygen limitation in warming oceans. Here we report unique metabolic temperature sensitivities for the myriad of vertically migrating oceanic species that daily cross depth-related gradients in temperature and oxygen. In these taxa, selection favours high metabolic activity for predator–prey interactions in warm shallow water and hypoxia tolerance in the cold at depth. These diverging selective pressures result in thermal insensitivity of oxygen supply capacity and enhanced thermal sensitivity of active metabolic rate. Aerobic scope is diminished in the cold, well beyond thermodynamic influences and regardless of ambient oxygen levels, explaining the native distributions of tropical migrators and their recent range expansions following warming events. Cold waters currently constitute an energetic barrier to latitudinal range expansion in vertical migrators. As warming due to climate change approaches, and eventually surpasses, temperatures seen during past warming events, this energetic barrier will be relieved.
