我们过去关于海洋酸化的大部分研究都集中在（亚）生物水平上对pCO2增加的直接反应，但没有得出可以预测到自然环境中的发现。在回顾了最近主要关于海洋酸化效应的350篇文章的基础上，我们强调了常用实验方法的主要局限性。因此，最常见的调查类型，简化和严格控制的实验室实验，已经产生了大量的短期生理反应，酸化的研究结果，但任何外推到自然生态系统的水平仍然是有问题的。为此目的，一个升级的压力源的数量，个体发育阶段，物种，种群，代以及纳入波动强度的压力是必需的。因为最后一个方面似乎是最不认可的，我们更详细地处理在不同的时间和空间尺度的碳酸盐岩系统的自然波动。我们报告了非常罕见的调查，评估了自然pH值或pCO2波动的生物相关性。最后，我们恳求的情况下，更自然的研究方法，集成几个组织层面的响应侧，几个驱动程序，生物相互作用和环境波动在不同的尺度。
Much of our past research on ocean acidification has focussed on direct responses to pCO2 increase at the (sub-) organism level, but does not produce findings that can be projected into the natural context. On the basis of a review of ~350 recent articles mainly on ocean acidification effects, we highlight major limitations of commonly used experimental approaches. Thus, the most common type of investigation, simplified and tightly controlled laboratory experiments, has yielded a wealth of findings on short-term physiological responses to acidification, but any extrapolation to the natural ecosystem level is still problematic. For this purpose, an upscaling is required regarding the number of stressors, of ontogenetic stages, of species, of populations, of generations as well as the incorporation of fluctuating intensities of stress. Because the last aspect seems to be the least recognised, we treat in more detail the natural fluctuations of the carbonate system at different temporal and spatial scales. We report on the very rare investigations that have assessed the biological relevance of natural pH or pCO2 fluctuations. We conclude by pleading the case for more natural research approaches that integrate several organisational levels on the response side, several drivers, biological interactions and environmental fluctuations at various scales.
