2019 USGS Alaska Annual Science ReportShorebirds adjust spring arrival schedules with variable environmental conditions: Four decades of assessment on the Yukon–Kuskokwim Delta, Alaska
Arctic summers are brief, and there has been strong selection for migratory birds to arrive in Arctic nesting areas as early as possible to time breeding with peak food availability and complete reproduction. The timing of emergence of nesting habitat in spring is, however, extremely variable in the Arctic, and few long-term studies have examined...
Shuford, W. David; Gill, Robert E.; Handel, Colleen M.; Ely, Craig R.; McCaffery, Brian; Gill, Robert E.Survey-based assessment of the frequency and potential impacts of recreation on polar bears
Conservation plans for polar bears (Ursus maritimus) typically cannot prescribe management actions to address their primary threat: sea ice loss associated with climate warming. However, there may be other stressors that compound the negative effects of sea ice loss which can be mitigated. For example, Arctic tourism has...
Rode, Karyn D.; Fortin, Jennifer K.; Garshelis, Dave; Dyck, Markus; Sahanatien, Vicki; Atwood, Todd C.; Belikov, Stanislav; Laidre, Kristin L.; Miller, Susanne; Obbard, Martyn E.; Vongraven, Dag; Ware, Jasmine V.; Wilder, JamesUse of landscape simulation modeling to quantify resilience for ecological applications
Goals of fostering ecological resilience are increasingly used to guide U.S. public land management in the context of anthropogenic climate change and increasing landscape disturbances. There are, however, few operational means of assessing the resilience of a landscape or ecosystem. We present a method to evaluate resilience using simulation...
Keane, Robert; Loehman, Rachel A.; Holsinger, Lisa M.; Falk, Donald A.; Higuera, Phil E; Hood, Sharon; Hessburg, Paul F.Movements and dive patterns of pygmy killer whales (Feresa attenuata) released in the Gulf of Mexico following rehabilitation
The habits and habitats of pygmy killer whales (Feresa attenuata) in the Gulf of Mexico (GoM) are poorly known outside of strandings and line-transect surveys. Two adult male pygmy killer whales were found live-stranded in the state of Mississippi (USA) on 1 September 2015 and were subsequently rehabilitated and returned to the offshore waters of...
Pulis, Eric; Wells, Randall S.; Schorr, Gregory S.; Douglas, David C.; Samuelson, Mystera M.; Solangi, MobySpring temperature, migration chronology, and nutrient allocation to eggs in three species of arctic‐nesting geese: Implications for resilience to climate warming
The macronutrients that Arctic herbivores invest in their offspring are derived from endogenous reserves of fat and protein (capital) that females build prior to the period of investment or from foods they consume concurrently with investment (income). The relative contribution from each source can be influenced by temporal and environmental...
Hupp, Jerry W.; Ward, David H.; Soto, David X.; Hobson, Keith A.Genetic evidence supports sporadic and independent introductions of subtype H5 low pathogenic avian influenza A viruses from wild birds to domestic poultry in North America
Wild bird–origin influenza A viruses (IAVs or avian influenza) have led to sporadic outbreaks among domestic poultry in the United States (US) and Canada, resulting in economic losses through the implementation of costly containment practices and destruction of birds. We used evolutionary analyses of virus sequence data to determine that 78 H5 low...
Li, Lei; Bowman, Andrew S.; DeLiberto, Thomas J.; Killian, Mary L.; Krauss, Scott; Nolting, Jacqueline M.; Torchetti, Mia Kim; Ramey, Andrew M.; Reeves, Andrew B.; Stallknecht, David E.; Webby, Richard J.; Wan, Xiu-FengIntroduction of Eurasian-origin H8N4 influenza A virus into North America via migratory birds
We identified a Eurasian-origin influenza A(H8N4) virus in North America by sampling wild birds in western Alaska, USA. Evidence for repeated introductions of influenza A viruses into North America by migratory birds suggests that intercontinental dispersal might not be exceedingly rare and that our understanding of viral establishment is...
Ramey, Andrew M.; Reeves, Andrew B.; Donnelly, Tyrone F.; Poulson, Rebecca L.; Stallknecht, David E.Evaluating time-removal models for estimating availability of boreal birds during point count surveys: Sample size requirements and model complexity
We used conventional and finite mixture removal models with and without time-varying covariates to evaluate availability given presence for 152 bird species using data from point counts in boreal North America. We found that the choice of model had an impact on the estimability of unknown model parameters and affected the bias and variance of...
Solymos, Peter; Matsuoka, Steven M.; Cumming, Steven G.; Stralberg, Diana; Fontaine, Patricia C.; Schmiegelow, Fiona K. A.; Song, Samantha J.; Bayne, Erin M.Aerial surveys of sea otters (Enhydra lutris) in Lower Cook Inlet, Alaska, May, 2017
Portions of two stocks of northern sea otters (Enhydra lutris kenyoni) occur in Lower Cook Inlet (LCI), Alaska. Sea otters on the west side of LCI are considered part of the southwest Alaska stock; sea otters occupying eastern LCI are considered part of the southcentral Alaska stock. Information concerning the distributions and abundance of sea...
Gerlach-Miller, Joel; Esslinger, George G.; Weitzman, BenFlyway structure in the circumpolar greater white‐fronted goose
Dispersal and migratory behavior are influential factors in determining how genetic diversity is distributed across the landscape. In migratory species, genetic structure can be promoted via several mechanisms including fidelity to distinct migratory routes. Particularly within North America, waterfowl management units have been delineated...
Wilson, Robert E.; Ely, Craig R.; Talbot, Sandra L.A transcriptome resource for the Arctic Cod (Boreogadus saida)
Arctic Cod (Boreogadus saida) serve as an important link in Arctic food webs and are thus considered an important species for environmental monitoring. RNA-Seq was conducted on samples from wild-collected individuals representing various age classes and tissue types to obtain as complete a transcriptome as possible on an Illumina MiSeq, which...

The liverwort flora of Attu Island, the westernmost Aleutian Island in the United States, was studied to assess species diversity in the hyperoceanic sector of the northern boreal subzone. The field study was undertaken in sites selected to represent a spectrum of environmental variation, primarily within the eastern part of the island. Data were...

Alaska is a land of great opportunity for scientific research, according to the director of the U.S. Geological Survey.
The water quality of the Fortymile River -- a beautiful, wild and scenic river in the remote part of east-central Alaska -- has not been adversely impacted by selected suction-dredge gold placer mining operations, according to an integrated study under way by the U.S. Geological Survey and the Alaska Department of Natural Resources.
The Aleutian Islands of Alaska and the Kamchatka Peninsula of the Russian Far East are often thought of as desolate windswept outposts along the northern Pacific rim, yet this is a heavily traveled region.
Torrents of meltwater are unleashed suddenly from the margins of the great moving sheets of snow and ice, known as glaciers. In Alaska, these pulses of activity, called "outburst floods," are usually caused by the failure of ice dams that restrain the meltwater of glacial margin lakes.
A new fact sheet from the U.S. Geological Survey provides results of the latest assessment of petroleum resources in the 1002 area of the Arctic National Wildlife Refuge, including new estimates of how much petroleum may be present. The 1002 area, defined by the Alaska National Interest Lands Conservation Act of 1980, includes most of the coastal plain of the Arctic Refuge and covers about 1.5 mil
A new, computer-generated, digital map of Alaska was presented to Gov.Tony Knowles and John Shively, Commissioner of the Alaska Department of Natural Resources, today by Gordon Nelson, State Representative for the U.S. Geological Survey (USGS).
A computer-generated map published by the U.S. Geological Survey provides a striking portrayal of Alaska’s varied landscape.
China and Indonesia suffered the deadliest and most destructive earthquakes in 1996, while the U.S. remained relatively quiet according to scientists at the U.S. Geological Survey, Department of the Interior. The last deadly earthquake in the U.S. was the 1994 Northridge, Calif., quake that took 60 lives.
Just in time for Christmas, Pavlof volcano in Alaska and Montserrat volcano in the Caribbean are more active but are not expected to alter or delay Santa’s trip around the world, according to the U.S. Geological Survey.
From glaciers and lava flats to white spruce woodlands and bog communities, a new U.S. Geological Survey report will aid scientists, managers and planners in organizing environmental data.
A magnitude 6.4 earthquake occurred Thurs., Oct. 5, 1995, in Alaska, about 40 miles northwest of Fairbanks, at 9:23 p.m. Alaska Daylight Time (1:23 a.m. EDT, Oct. 6), according to the U.S. Geological Survey.
"After seven months of near-stagnation, Alaska’s Bering Glacier resumed surging. Between May 19th and June 1, part of the glacier advanced almost half a mile (about 2,500 ft). As of mid-September, the surge was continuing," said Bruce F. Molnia, leader of the U.S. Geological Survey’s Bering Glacier Research Project.
