Dynamics of plasma nutrients and metabolites in moulting macaroni (Eud yptes chrysolophus) and gentoo (Pygoscelis papua) penguins
1.1. Dynamics of plasma nutrients and metabolites in moulting macaroni (Eudyptes chrysolophus) and gentoo (Pygoscelis papua) penguins were studied.2.2. The late moult macaroni and gentoo penguins had significantly elevated levels of total lipid and cholesterol, α-tocopherol (vitamin E) and alkaline...
