Variability in tissue-specific trophic discrimination factors (∆13C and ∆15N) between Antarctic krill Euphausia superba and free-ranging Pygoscelis penguins
International audience For top consumers in marine environments, trophic discrimination factors (Δ13C and Δ15N) between food and consumers’tissues are expected to be similar among related species. However, few studies conducted in the laboratory indicate a largevariability among species, which shoul...
