气候变化正在导致全球海洋变暖、脱氧和酸化。然而,由于海洋条件的不同,气候变化的表现可能在地方尺度上有所不同。局部尺度上的高温和低氧等应激源的变化可能会导致不同的生物反应和空间避难所,以躲避气候影响。我们在墨西哥纳蒂维达岛近岸两个相距约2.5 公里的地点和两个相距约2 0 0 m的地点进行了外植实验,以评估当地海洋条件(变暖和缺氧)对鲍鱼幼鱼性能的影响。在这里,我们展示了鲍鱼的生长和死亡率映射到不同地点和地点的压力暴露的变异性。这些见解表明,在面对气候变化时,旨在维持和恢复有价值的海洋物种的管理决策需要了解当地环境条件的变化情况。
Climate change is causing warming, deoxygenation, and acidification of the global ocean. However, manifestation of climate change may vary at local scales due to oceanographic conditions. Variation in stressors, such as high temperature and low oxygen, at local scales may lead to variable biological responses and spatial refuges from climate impacts. We conducted outplant experiments at two locations separated by ~2.5 km and two sites at each location separated by ~200 m in the nearshore of Isla Natividad, Mexico to assess how local ocean conditions (warming and hypoxia) may affect juvenile abalone performance. Here, we show that abalone growth and mortality mapped to variability in stress exposure across sites and locations. These insights indicate that management decisions aimed at maintaining and recovering valuable marine species in the face of climate change need to be informed by local variability in environmental conditions.
