John M Pearce, Ph.D.
I am the Manager of the Wetlands and Terrestrial Ecosystems Office and oversee a broad program of science research and outreach on avian disease, wildlife response to change, environmental health, and population genetics. Our research is primarily focused in the state of Alaska, but often includes adjacent regions that share wildlife resources with Alaska.

Science and Products
Tracking Data for Tundra Swan (Cygnus columbianus)
Available here are tracking data of Tundra Swans, a species that nests in coastal areas throughout Alaska and winters across a broad area of North America from the Pacific to Atlantic coasts. These data were collected to better understand the timing and patterns of migratory movements and seasonal use of habitats in breeding, wintering, and migratory areas of North America.
Tracking Data for Yellow-billed Loon (Gavia adamsii)
Available here are tracking data of Yellow-billed loons, a species that breeds in coastal areas of western and northern Alaska and adjacent regions of Russia and Canada. This species winters along the Pacific coasts of North America and Eurasia. These data were collected to better understand the patterns of migratory movements and seasonal use of different regions of Alaska
Swan Research
USGS research on swans in Alaska has focused on pathogens, contaminants, and demographic rates in each of the different breeding areas of Alaska. The vastly different migration patterns of swans in Alaska means that there are multiple factors on the wintering grounds and during migration that may influence population size and trends.
Community Outreach and Engagement
It is critically important that Alaska Native, rural communities and tribal organizations and Alaska co-management councils are kept informed of USGS research activities and findings. Involvement of and collaboration with students also provides valuable perspectives to USGS science. This page offers information on how USGS communicates its activities and seeks opportunities to gain important...
Tracking Data for Blue-winged Teal (Anas discors)
Available here are tracking data of Blue-winged Teal, a duck species that breeds throughout much of North America and whose wintering range includes neotropical areas of the Caribbean and Central and South America, thus providing a migratory link between the continents of North and South America. These data were collected to better understand the timing and patterns of migratory movement of...
Tracking Data for Northern Pintail (Anas acuta)
Available here are tracking data of Northern Pintails, a duck species that, in Alaska, nests throughout the state and in adjacent regions of Russia and Canada. These data were collected to better understand the timing and patterns of migratory movements of Northern Pintails from wintering grounds in Japan as part of a project on the possible spread of Eurasian forms of avian influenza to North...
Spatial and Temporal Maps of Population Change of Waterbirds on Alaska's North Slope
A main objective of the USGS Changing Arctic Research Initiative is to quantify and provide projections of the responses of wildlife species and their habitats to ecosystem change in the Arctic. The following project provides information for Department of Interior agencies, industry, and other stakeholders related to this objective.
Changing Arctic Ecosystems
The USGS Changing Arctic Ecosystems Initiative will enhance the long-term science foundation needed by the U.S. Department of the Interior and other partners.

Algal toxins in Alaskan seabirds: Evaluating the role of saxitoxin and domoic acid in a large-scale die-off of Common Murres
Elevated seawater temperatures are linked to the development of harmful algal blooms (HABs), which pose a growing threat to marine birds and other wildlife. During late 2015 and early 2016, a massive die-off of Common Murres (Uria algae; hereafter, murres) was observed in the Gulf of Alaska coincident with a strong marine heat wave. Previous...

Visualizing populations of North American sea ducks: Maps to guide research and management planning
North American sea ducks generally breed in mid- to northern-latitude regions and nearly all rely upon marine habitats for much of their annual cycle. Most sea duck species remained poorly studied until the 1990s when declines were noted in several species and populations. Subsequent research, much of which was funded by the Sea Duck Joint Venture...

Summary of wildlife-related research on the coastal plain of the Arctic National Wildlife Refuge, Alaska, 2002–17
We summarize recent (2002–17) publicly available information from studies within the 1002 Area of the Arctic National Wildlife Refuge as well as terrestrial and coastal ecosystems elsewhere on the Arctic Coastal Plain that are relevant to the 1002 Area. This report provides an update on earlier research summaries on caribou (Rangifer tarandus),...
Pearce, John M.; Flint, Paul L.; Atwood, Todd C.; Douglas, David C.; Adams, Layne G.; Johnson, Heather E.; Arthur, Stephen M.; Latty, Christopher J. Vectors, hosts, and control measures for Zika virus in the Americas
We examine Zika virus (ZIKV) from an ecological perspective and with a focus on the Americas. We assess (1) the role of wildlife in ZIKV disease ecology, (2) how mosquito behavior and biology influence disease dynamics, and (3) how nontarget species and ecosystems may be impacted by vector control programs. Our review suggests that free-ranging,...
Thompson, Sarah J.; Pearce, John M.; Ramey, Andrew M. Environment and science: Chapter 9
Alaska is part of an international circumpolar North, which makes the United States an Arctic nation. Alaska is a place of Indigenous ingenuity and adaptation, a place where environmental extremes challenge the ways of living. In its more recent history, Alaska has been a place of resources and influx-a land known best for what it provides. This...
Pearce, John M.; Talbot, Sandra L. Surveillance for Eurasian-origin and intercontinental reassortant highly pathogenic influenza A viruses in Alaska, spring and summer 2015
Background: Eurasian-origin and intercontinental reassortant highly pathogenic (HP) influenza A viruses (IAVs) were first detected in North America in wild, captive, and domestic birds during November–December 2014. Detections of HP viruses in wild birds in the contiguous United States and southern Canadian provinces continued into winter and...

Wild bird surveillance for highly pathogenic avian influenza H5 in North America
It is unknown how the current Asian origin highly pathogenic avian influenza H5 viruses arrived, but these viruses are now poised to become endemic in North America. Wild birds harbor these viruses and have dispersed them at regional scales. What is unclear is how the viruses may be moving from the wild bird reservoir into poultry holdings. Active...
Flint, Paul L.; Pearce, John M.; Franson, J. Christian; Derksen, Dirk V. Evidence that dorsally mounted satellite transmitters affect migration chronology of Northern Pintails
We compared migration movements and chronology between Northern Pintails (Anas acuta) marked with dorsally mounted satellite transmitters and pintails marked only with tarsus rings. During weekly intervals of spring and autumn migration between their wintering area in Japan and nesting areas in Russia, the mean distance that ringed pintails had...

USGS highly pathogenic avian influenza research strategy
Avian influenza viruses are naturally occurring in wild birds such as ducks, geese, swans, and gulls. These viruses generally do not cause illness in wild birds, however, when spread to poultry they can be highly pathogenic and cause illness and death in backyard and commercial farms. Outbreaks may cause devastating agricultural economic losses...
