Lipids from stomach oil of procellariiform seabirds document the importance of myctophid fish in the Southern Ocean

We investigated the relative importance of myctophid fish and Antarctic krill in the diet of adult flying seabirds of the Southern Ocean. The main prey of short-tailed shearwaters Puffinus tenuirostris (P. ten.), white-chinned petrels Procellaria aequinoctialis (P. aeq.), blue petrels Halobaena caer...

Description
Summary:We investigated the relative importance of myctophid fish and Antarctic krill in the diet of adult flying seabirds of the Southern Ocean. The main prey of short-tailed shearwaters Puffinus tenuirostris (P. ten.), white-chinned petrels Procellaria aequinoctialis (P. aeq.), blue petrels Halobaena caerulea (H. cae.), thin-billed prions Pachyptila belcheri (P. bel.), and Antarctic prions Pachyptila desolata (P. des.) were mostly deduced from the lipid analysis of adult stomach oils. More than 97 % of the 125 analyzed oils mainly consisted of wax esters (WEs) and triacylglycerols (TAGs) (.70 % of total lipids). WE fatty alcohol (FAlc), WE fatty acid (FA), and TAG-FA profiles clearly segregated P. aeq. from P. ten., with smaller, but still significant, differences among the three other
