Alaska Science Center
Home
The Alaska Science Center provides objective and timely data, information, and research findings about the earth and its flora and fauna to Federal, State, and local resource managers and the public to support sound decisions regarding natural resources, natural hazards, and ecosystems in Alaska and circumpolar regions.
Spotlight on Science
The Condor: Ornithological Applications has compiled a list of research publications, including seven from USGS authors, on northern latitude bird species. These describe responses of Alaskan birds to numerous environmental variabilities.

Study of Alaskan Landslide Could Improve Tsunami Modeling
A rare submarine landslide provides researchers with a reference point for modeling the biggest tsunamis. (EOS article)
New tsunami evidence along one of Earth’s largest faults, the Alaska-Aleutian megathrust
Recent geological studies of a key section of the Aleutian Island chain of Alaska suggest Aleutian tsunamis may occur more frequently than previously understood.

Improving population estimates of threatened spectacled eiders: Correcting aerial counts for visibility bias
Listed as threatened under the Endangered Species Act in 1993, the Spectacled Eider (Somateria fischeri) population in western Alaska has since rebounded, prompting an assessment of their suitability for delisting. This assessment, however, is limited by aerial-based population estimates that are incompletely corrected for unobserved eiders....
Lewis, Tyler; Michael Swaim; Schmutz, Joel A.; Julian Fischer Early emergence of mcr-1-positive Enterobacteriaceae in gulls from Spain and Portugal
We tested extended‐spectrum β‐lactamase producing bacteria from wild gulls (Larusspp.) sampled in 2009 for the presence of mcr‐1. We report the detection of mcr‐1 and describe genome characteristics of four Escherichia coli and one Klebsiella pneumoniaeisolate from Spain and Portugal that also exhibited colistin resistance...
Ahlstrom, Christina; Ramey, Andrew M.; Woksepp, Hanna; Bonnedahl, Jonas Repeated detection of carbapenemase-producing Escherichia coli in gulls inhabiting Alaska, USA
We report the first detection of carbapenemase-producing Escherichia coli in Alaska and in wildlife in the United States. Wild bird (gull) feces sampled at three locations in Southcentral Alaska yielded isolates that harbored plasmid-encoded blaKPC-2 or chromosomally-encoded blaOXA-48, and genes associated with...
