Life-history and connectivity shape the viromes of a migratory and river-resident galaxiid

Ryan R. Easton, Stephanie J. Waller, Hayley Bosley…·Jemma L. Geoghegan

The paper compares viromes of two galaxiid fish with different life-history strategies, finding that the river-resident species has higher viral diversity than the migratory species.

Avian influenza virus surveillance across New Zealand and its subantarctic islands detects H1N9 in migratory shorebirds, but not 2.3.4.4b HPAI H5N1

Stephanie J. Waller, Janelle R. Wierenga, Lia Heremia…·Jemma L. Geoghegan

The study sampled wild birds in New Zealand and its territories, finding no HPAI H5N1 but detecting H1N9 in red knots during 2023-2024 migration.
