Journal ArticleDOI
Using RRT-PCR analysis and virus isolation to determine the prevalence of avian influenza virus infections in ducks at Minto Flats State Game Refuge, Alaska, during August 2005
Jonathan A. Runstadler,George M. Happ,Richard D. Slemons,Zong-Mei Sheng,N. Gundlach,Michael J. Petrula,Dennis A. Senne,Jacqueline M. Nolting,D. L. Evers,A. Modrell,Heather J. Huson,S. Hills,T. Rothe,T. Marr,Jeffery K. Taubenberger +14 more
TL;DR: Success during 2005 indicates Minto Flats will be a valuable study site for a longitudinal research project designed to gain further insight into the natural history, evolution, and ecology of AIV in wild birds.
Journal ArticleDOI
Intercontinental reassortment and genomic variation of low pathogenic avian influenza viruses isolated from northern pintails (Anas acuta) in Alaska: Examining the evidence through space and time
Andrew M. Ramey,John M. Pearce,Paul L. Flint,Hon S. Ip,Dirk V. Derksen,J. Christian Franson,Michael J. Petrula,Bradley D. Scotton,Kristine M. Sowl,Michael L. Wege,Kimberly A. Trust +10 more
TL;DR: Results show detection of foreign lineage gene segments to be most likely at sample locations on the Alaska Peninsula and least likely along the Southern Alaska Coast, suggesting maintenance in avian hosts that migrate to Alaska each year from Asia or in hosts that remain in Alaska throughout the year.
Journal ArticleDOI
Interspecific exchange of avian influenza virus genes in Alaska: The influence of trans-hemispheric migratory tendency and breeding ground sympatry
John M. Pearce,Andrew B. Reeves,Andrew M. Ramey,Jerry W. Hupp,Hon S. Ip,Mark R. Bertram,Michael J. Petrula,Bradley D. Scotton,Kimberly A. Trust,Brandt W. Meixell,Jonathan A. Runstadler +10 more
TL;DR: Mallards are likely infected with Asian‐origin viruses via interspecific transfer from species with regular migrations to the Eastern Hemisphere, suggesting transmission from other avian species migrating inter‐hemispherically or the common occurrence of endemic Alaskan viruses containing segments of Eurasian origin.
Journal ArticleDOI
Reproductive strategies of northern geese: why wait?
Craig R. Ely,Karen S. Bollinger,Roseann V. Densmore,Thomas C. Rothe,Michael J. Petrula,John Y. Takekawa,D.L. Orthmeyer +6 more
TL;DR: In this article, the authors radiotracked winter-marked Tule Greater White-fronted Geese (Anser albifrons elgasi; hereafter “Tule Geese”; n = 116) from the time of their arrival in Alaska through nesting.
Migration chronology, routes, and distribution of pacific flywaypopulation lesser sandhill cranes
TL;DR: The authors used satellite telemetry to monitor movements of lesser sandhill cranes (Grus c. canadensis) captured in the upper Cook Inlet and Bristol Bay regions of Alaska.
