| Resumen: | Rising levels of anthropogenic carbon dioxide in the atmosphere are
acidifying the oceans and producing diverse and important effects on
marine ecosystems, including the production of fatty acids (FAs) by
primary producers and their transfer through food webs. FAs,
particularly essential FAs, are necessary for normal structure and
function in animals and influence composition and trophic structure of
marine food webs. To test the effect of ocean acidification (OA) on the
FA composition of fish, we conducted a replicated experiment in which
larvae of the marine fish red drum (Sciaenops ocellatus) were reared under a climate change scenario of elevated CO2
levels (2100 µatm) and under current control levels (400 µatm). We
found significantly higher whole-body levels of FAs, including nine of
the 11 essential FAs, and altered relative proportions of FAs in the
larvae reared under higher levels of CO2. Consequences of
this effect of OA could include alterations in performance and survival
of fish larvae and transfer of FAs through food webs. |
