Abstract

Omega-3 long-chain polyunsaturated fatty acids (n-3 LC-PUFA) are essential fatty acids for the growth, development and survival of virtually all organisms. There is increasing evidence that anthropogenic climate change has a direct and indirect impact on the availability of natural n-3 LC-PUFA. However, this information is fragmented and not well organized. Therefore, this article reviewed published data from laboratory experiments, field experiments and model simulations to reveal the impact of climate change on the global supply of natural n-3 LC-PUFA and how this will limit the availability of n-3 LC-PUFA in the future food web. In general, climate change can significantly reduce the availability of natural n-3 LC-PUFA in grazing food webs in the following ways: 1) decrease the total biomass of phytoplankton and shift the plankton community structure to a smaller size, which also reduce the biomass of animals in higher trophics; 2) reduce the n-3 LC-PUFA content and/or quality (n-3: n-6 ratio) of all marine organisms; 3) reduce the transfer efficiency of n-3 LC-PUFA in grazing food web. In addition, as an anthropogenic climate adaptation measure, this review also proposed some alternative sources of n-3 LC-PUFA and determined the direction of future research. The information in this article is very useful for providing a critical analysis of the impact of climate change on the supply of natural n-3 LC-PUFA. Such information will aid to establish climate adaptation or management measures, and determine the direction of future research.

气候变化与n-3 LC-PUFA有效性。
Omega-3长链多不饱和脂肪酸(n-3 LC-PUFA)是几乎所有生物体生长、发育和生存所必需的脂肪酸。越来越多的证据表明,人为气候变化对天然n-3 LC-PUFA的有效性有直接和间接的影响。然而,这些信息是碎片化的,没有很好地组织起来。因此,本文回顾了实验室实验、野外实验和模型模拟的已发表数据,以揭示气候变化对全球天然n-3 LC-PUFA供应的影响,以及这将如何限制n-3 LC-PUFA在未来食物网中的可用性。总体而言,气候变化可通过以下方式显著降低放牧食物网天然n-3 LC-PUFA的有效性:1)降低浮游植物的总生物量,使浮游生物群落结构向较小规模转移,同时降低高营养性动物的生物量;2)降低所有海洋生物的n-3 LC-PUFA含量和/或质量(n-3: n-6比);3)降低n-3 LC-PUFA在放牧食物网中的转移效率。此外,作为一种人为气候适应措施,本文还提出了n-3 LC-PUFA的一些替代来源,并确定了未来的研究方向。本文中的信息对于提供气候变化对天然n-3 LC-PUFA供应的影响的批判性分析非常有用。这些信息将有助于制定气候适应或管理措施,并确定未来研究的方向。

期刊介绍: The significance of lipids as a fundamental category of biological compounds has been widely acknowledged. The utilization of our understanding in the fields of biochemistry, chemistry, and physiology of lipids has continued to grow in biotechnology, the fats and oils industry, and medicine. Moreover, new aspects such as lipid biophysics, particularly related to membranes and lipoproteins, as well as basic research and applications of liposomes, have emerged. To keep up with these advancements, there is a need for a journal that can evaluate recent progress in specific areas and provide a historical perspective on current research. Progress in Lipid Research serves this purpose.
