Effects of Lipid Extraction on δ 13 C and δ 15 N Values in Seabird Muscle , Liver and Feathers

We determined whether lipid extraction of seabird muscle, liver and feathers is required for δC and δN analysis, based on a study of Barau’s Petrels (Pterodroma baraui) and Whitetailed Tropicbirds (Phaethon lepturus). Samples were analyzed for stable isotopes before and after lipid removal. Lipid-free muscle and liver were significantly enriched in C… CONTINUE READING
