 ・ We compare vitamin A levels between breeding colonies where adults forage within and outside the affected zone.

 ・ Flegdlings from the colony from the affected zone display reduced level of vitamin A.

 ・ Exposure to radiation reduces levels of antioxidants [that] can cause teratogenic or mutagenetic effects… distributions of Streaked Shearwaters from Mikura Island (MKR) during the post egg-laying period coincide with the Fukushima nuclear plume while the breeding colony on Birou Island (BRU) [approx. 600 miles from Fukushima Daiichi] lies outside the affected zone… fledglings from MKR [approx. 100 miles south of Tokyo and 250 miles from Fukushima Daiichi] displayed significantly reduced vitamin A levels… these depletions most likely result from radiation exposure due to the Fukushima nuclear accident, implying that the risk of radionuclide contamination is considerably elevated for Streaked Shearwaters on MKR, where more than 60% of the world’s population breeds. While additional negative impacts are expected due to delayed effects of radionuclide transport via biomagnification in the food chain, this study highlights the potential immediate and worrisome consequences of the Fukushima
