Trophic transfer of essential elements in the clownfish Amphiprion ocellaris in the context of ocean acidification
International audience Little information exists on the effects of ocean acidification (OA) on the digestive and post-digestive processes in marine fish. Here, we investigated OA impacts (Δ pH = 0.5) on the trophic transfer of select trace elements in the clownfish Amphiprion ocellaris using radiotr...
