| Abstract |
The lipid composition of organisms will change as surrounding physicochemical conditions change to ensure that membranes and other essential biological functions stay intact, a process known as homeoviscous adaptation. Holm et al. used high-resolution mass spectrometry to analyze the lipid composition of surface layer plankton sampled largely from the Atlantic Ocean (see the Perspective by Sepúlveda and Cantarero). Although a few lipid species constitute the bulk of the plankton lipidome, organisms living in cold (−2°C) regions have threefold more unsaturated fatty acids than those in warm (29°C) waters. Declines in unsaturation of planktonic essential fatty acids under different scenarios of climate change could have negative consequences for food webs and ultimately for fisheries. |
