Plasma tocopherol, retinol, and carotenoid concentrations in free-ranging Humboldt penguins (Spheniscus humboldti) in Chile
Abstract 10.1002/(SICI)1098-2361(1996)15:23.3.CO;2-L Plasma retinol and α-tocopherol concentrations were measured in heparinized blood samples collected from 51 free-ranging adult Humboldt penguins (Sphenicus humboldti) residing at two colonies off the Chilean coast.
