虽然关于气候对海洋生态系统的影响的文献记录有很长的历史，但潜在的过程往往难以捉摸。本文综述了生态系统对气候变率的一些响应，并讨论了气候作用的可能机制。气候和海洋学变量，如温度、海冰、湍流和平流，对海洋生物的影响，讨论了它们对生长、分布、繁殖、活动率、招募和死亡率的影响。生物往往被限制在特定的温度范围内，实验结果表明，只有在这些范围内才能通过通风和循环提供足够的氧气。还讨论了气候强迫通过对食物网的影响而产生的间接影响。本文提出了提高我们对气候与生态系统变化联系过程的认识所需的研究和数据需求，以及我们对预测生态系统对未来气候变化情景的反应能力的评估。(C) 2009 Elsevier B.V.版权所有
While documentation of climate effects on marine ecosystems has a long history, the underlying processes have often been elusive. In this paper we review some of the ecosystem responses to climate variability and discuss the possible mechanisms through which climate acts. Effects of climatological and oceanographic variables, such as temperature, sea ice, turbulence, and advection, on marine organisms are discussed in terms of their influence on growth, distribution, reproduction, activity rates, recruitment and mortality. Organisms tend to be limited to specific thermal ranges with experimental findings showing that sufficient oxygen supply by ventilation and circulation only occurs within these ranges. Indirect effects of climate forcing through effects on the food web are also discussed. Research and data needs required to improve our knowledge of the processes linking climate to ecosystem changes are presented along with our assessment of our ability to predict ecosystem responses to future climate change scenarios.
