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 Informing the Status and Trends of Migratory Birds
Through the Changing Arctic Ecosystems (CAE) Initiative, the U.S. Geological Survey (USGS) is informing key resource management decisions by better understanding how wildlife populations of special interest to the Department of the Interior (DOI) are responding to rapid physical changes in the Arctic. Below are some examples of how CAE research is...
Terrestrial Wildlife and Habitats
The USGS conducts research on trust Department of Interior migratory bird and mammal species and their habitats to inform agencies such as the US Fish and Wildlife Service, Bureau of Land Management and National Park Service in their natural resource management decisions.
The Alaska Science Center focuses its research on a wide range of species important to the Department.
Wildlife Disease and Genetics
Alaska is a geographically important focus of the national biosurveillance program and the study of Wildlife Disease and Environmental Health because it lies within the migratory routes of birds that move between North America and East Asia.

Sea Duck Research
At the USGS Alaska Science Center, research on sea ducks has been designed to anticipate and address priority information needs of management agencies. Until recently, very little was known about sea ducks in Alaska in terms of migration patterns and general biology. Therefore, much of our past work focused on individual species, their migration, population demography, and ecology to fill...

Wildlife Disease and Environmental Health in Alaska
Environmental health is defined by connections between the physical environment, ecological health, and human health. Current research within the U.S. Geological Survey (USGS) recognizes the importance of this integrated research philosophy, which includes study of disease and pollutants as they pertain to both wildlife and humans. Due to its key geographic location and significant wildlife...
Waterfowl Research
Scientists at the USGS Alaska Science Center have conducted research on waterfowl species (ducks, geese, and swans) in Alaska since the 1970s. Because Alaska is an international crossroads of migratory bird flyways, with millions of birds from Asia and North America breeding in Alaska each summer, USGS research has also taken place in adjacent countries (Russia, Japan, Canada, Mexico) and in...
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),...

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...

U.S. Geological Survey science strategy for highly pathogenic avian influenza in wildlife and the environment (2016–2020)
IntroductionThrough the Science Strategy for Highly Pathogenic Avian Influenza (HPAI) in Wildlife and the Environment, the USGS will assess avian influenza (AI) dynamics in an ecological context to inform decisions made by resource managers and policymakers from the local to national level. Through collection of unbiased scientific information on...

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...

Changing arctic ecosystems—What is causing the rapid increase of snow geese in northern Alaska?
Through the Changing Arctic Ecosystems (CAE) initiative, the U.S. Geological Survey (USGS) informs key resource management decisions for Arctic Alaska by providing scientific information on current and future ecosystem response to a warming climate. The Arctic Coastal Plain (ACP) of northern Alaska is a key study area within the USGS CAE...

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...

Conceptual data modeling of wildlife response indicators to ecosystem change in the Arctic
Large research studies are often challenged to effectively expose and document the types of information being collected and the reasons for data collection across what are often a diverse cadre of investigators of differing disciplines. We applied concepts from the field of information or data modeling to the U.S. Geological Survey (USGS) Changing...
Walworth, Dennis H.; Pearce, John M. Forecasting wildlife response to rapid warming in the Alaskan Arctic
Arctic wildlife species face a dynamic and increasingly novel environment because of climate warming and the associated increase in human activity. Both marine and terrestrial environments are undergoing rapid environmental shifts, including loss of sea ice, permafrost degradation, and altered biogeochemical fluxes. Forecasting wildlife responses...
