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.
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局部尺度上有所不同。局部尺度上的胁迫因素（如高温和低氧）的变化可能导致生物反应的变化和对气候影响的空间避难所。我们在墨西哥纳蒂维达德岛近岸的两个相距约 2.5 公里的地点和每个地点的两个相距约 200 米的地点进行了移植实验，以评估局部海洋条件（变暖与低氧）如何影响幼年鲍鱼的表现。在这里，我们表明，鲍鱼的生长和死亡率与暴露在压力下的变化有关，这种变化与地点和位置有关。这些研究结果表明，在气候变化的背景下，为了维持和恢复有价值的海洋物种，管理决策需要根据环境条件的局部变化来做出。
