Milk isotopic values demonstrate that nursing fur seal pups are a full trophic level higher than their mothers.

Abstract

RATIONALE In mammals including humans, mother-to-offspring transfer of nutrients has been the focus of several isotopic studies. Measurement of δ(13) C and δ(15) N values were mainly conducted on easily sampled tissues such as blood and hair that allow the calculation of apparent discrimination factors (∆(13) C and ∆(15) N) between offspring and maternal… (More)
