New paper about isotopic fractionation in Arctic seals

Our paper entitled “ Carbon, Nitrogen and Sulphur isotopic fractionation in captive juvenile hooded seal (Cystophora cristata ): application for diet analysis” just came out in Rapid Communications in Mass Spectrometry. We took advantage of a rare opportunity to analyse tissues from Arctic seals raised on controlled diets to investigate diet-consumer isotopic fractionation in multiple tissues, and compare experimentally measured trophic enrichment factors to outputs from SIDER, a recently published model. Congrats to Marianna Pinzone, the lead author!
