患者;酸化、脱氧和变暖正在加剧全世界海洋沿海水域的变化，可能对海洋生物和海洋经济造成严重后果。为了研究这些海洋学变化对关键生物过程的影响，我们测量了加州洋流大型海洋生态系统当前和预期未来条件对红鲍鱼（Haliotis rufescens）受精成功的影响。本研究利用实验室实验来评估鲍鱼在同时暴露于不同pH（梯度从7.95到7.2）、溶解氧（DO）（≈60和180 &mgr；m）水平下的受精成功率。kg SW)和温度（9,13和18°C）。施肥成功率随着pH值的降低而持续下降，但在低温（9°C -上涌）至平均（13°C）海水温度下，施肥成功率急剧下降至pH值7.55附近的阈值以下。DO的变化对施肥的影响可以忽略不计。相比之下，加州中部与厄尔尼诺Niño南方涛动条件相关的较暖水域（18°C）与pH值下降呈拮抗作用，在很大程度上降低了pH值阈值以下的强烈负面影响。研究多种环境驱动因素相互作用的实验方法，并努力表征生物在环境变化梯度中的功能响应，对于促进我们对海洋条件变化的现实世界后果的理解变得越来越重要。
&NA; Acidification, deoxygenation, and warming are escalating changes in coastal waters throughout the world ocean, with potentially severe consequences for marine life and ocean‐based economies. To examine the influence of these oceanographic changes on a key biological process, we measured the effects of current and expected future conditions in the California Current Large Marine Ecosystem on the fertilization success of the red abalone (Haliotis rufescens). Laboratory experiments were used to assess abalone fertilization success during simultaneous exposure to various levels of seawater pH (gradient from 7.95 to 7.2), dissolved oxygen (DO) (˜60 and 180 &mgr;m.kg SW) and temperature (9, 13, and 18 °C). Fertilization success declined continuously with decreasing pH but dropped precipitously below a threshold near pH 7.55 in cool (9 °C—upwelling) to average (13 °C) seawater temperatures. Variation in DO had a negligible effect on fertilization. In contrast, warmer waters (18 °C) often associated with El Niño Southern Oscillation conditions in central California acted antagonistically with decreasing pH, largely reducing the strong negative influence below the pH threshold. Experimental approaches that examine the interactive effects of multiple environmental drivers and also strive to characterize the functional response of organisms along gradients in environmental change are becoming increasingly important in advancing our understanding of the real‐world consequences of changing ocean conditions.
