Appendix B. Percentage of total mass of fatty acids in Spectacled Eider adipose tissue and potential invertebrate prey.

Table B1. Mean percentage mass (±1 SD) of fatty acids that each comprised >0.5% of the total mass of fatty acids in adipose tissue of Spectacled Eiders (n = number of eiders), and that cannot be synthesized by eiders, and in potential prey taxa (n = number of stations) south of St. Lawrence Island in the Bering Sea.
