Trace elements in feathers of Cape Petrel (Daption capense) from Antarctica

The Cape petrel (Daption capense) has circumpolar distribution and potential to be used as sentinels of trace elements levels in the Antarctic environment. This study measured trace elements in carcass feathers (n = 30) of this yet under-studied Procellariiform species, in King George Island, Antarctica. This non-invasive sampling method was useful for quantifying mercury (Hg), cadmium (Cd), selenium (Se), and to perform the sex identification...
