The paper screens seabird species for antibodies against avian cholera bacteria to assess spatial distribution and identify potential sentinels for disease monitoring.

This study tracks the spread and evolution of H5N1 in the sub-Antarctic and Antarctica, revealing long-distance dispersal and mammalian-adaptive mutations.

Whole-genome sequencing and geolocation tracking indicate that high pathogenicity avian influenza H5N1 reached Tristan skuas on remote Gough Island via sub-Antarctic marine networks linked to South Georgia rather than Africa.
