Proportions of diet estimated for crabeater seals, by MixSIAR using fatty acid or stable isotope data

Sources	Diet estimation for crabeater seals
	Fatty acids	Stable isotopes
E. superba	0.840 (0.799–0.867)	0.911 (0.836–0.972)
E. carlsbergi	0.012 (0.001–0.042)	0.041 (0.002–0.125)
E. antarctica	0.109 (0.042–0.150)	–
P. antarcticum	0.032 (0.002–0.145)	–
Pa_Ea	–	0.037 (0.002–0.110)

The group “Pa_Ea” corresponds to the combined isotope values of the fish P. antarcticum and E. antarctica
