Observational, virological, and serological data provide insights into an outbreak of highly pathogenic avian influenza among wild birds on the Yukon-Kuskokwim Delta, Alaska in 2022 Observational, virological, and serological data provide insights into an outbreak of highly pathogenic avian influenza among wild birds on the Yukon-Kuskokwim Delta, Alaska in 2022
In 2021–22, clade 2.3.4.4b highly pathogenic avian influenza (HPAI) viruses were introduced by wild birds into North America, leading to geographically widespread disease. In response to HPAI outbreaks throughout late 2021 and early 2022, we recorded observations of sick and dead birds, estimated abundance of carcasses, collected swab and sera samples to detect viruses, and monitored...
Spatial distribution and relative biomass of bigheaded carps in Lake Balaton, Hungary estimated from an environmental DNA survey Spatial distribution and relative biomass of bigheaded carps in Lake Balaton, Hungary estimated from an environmental DNA survey
Silver carp (Hypophthalmichthys nobilis), bighead carp (H. molitrix) and their hybrids, collectively known as bigheaded carps, have been introduced to Lake Balaton, Hungary. The current stock sizes are difficult to assess. We investigated environmental DNA (eDNA) techniques targeted for bigheaded carps, assessed the spatial distribution of eDNA in Lake Balaton, compared eDNA...
How to model a new invader? US-invaded range models outperform global or combined range models after 100 occurrences How to model a new invader? US-invaded range models outperform global or combined range models after 100 occurrences
Invasive species are an economic and ecological burden, and efforts to limit their impact are greatly improved with reliable maps based on species distribution models (SDMs). However, the potential distribution of new invaders is difficult to anticipate because they are still spreading with few observations in their invaded habitat. Therefore, an accepted practice in predicting the...

Avian Influenza Research
Since 2006, the USGS Alaska Science Center has been part of the State and Federal interagency team for the detection and response to highly pathogenic (HPAI) viruses in North America. Avian influenza or "bird flu" is a viral disease that primarily infects domestic poultry and wild birds. Avian influenza viruses are naturally occurring in wild birds such as ducks, geese, swans, and gulls. These...
USGS Invasive Carp Research 2025 Year in Review
This collection features new information products released between October 2024 and September 2025 that provide a scientific foundation for the management of invasive carp in the Mississippi River and Great Lakes basins and support the Presidential Memorandum “Protecting the Great Lakes from Invasive Carp”.
A Matter of Scales: USGS Science to Reduce Invasive Snake Impacts
The U.S. Geological Survey Ecosystem Mission Area plays a major role in invasive snake science across the country and the globe, ranging from research on improving snake detection to projects that enhance eradication. Our extensive science ultimately scales up to benefiting public health, energy transmission, tourism, and other key aspects of American prosperity.
