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.
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.
