Phenological mismatch in coastal western Alaska may increase summer season greenhouse gas uptake
High latitude ecosystems are prone to phenological mismatches due to climate change- driven advances in the growing season and changing arrival times of migratory herbivores. These changes have the potential to alter biogeochemical cycling and contribute to feedbacks on climate change by altering greenhouse gas (GHG) emissions of carbon dioxide (...

Legacy K/Ar and 40Ar/39Ar geochronologic data from the Alaska-Aleutian Range batholith of south-central Alaska
Sample descriptions and analytical data for more than 200 K/Ar and 40Ar/39Ar analyses from rocks of the Alaska-Aleutian Range batholith of south-central Alaska are reported here. Samples were collected over a period of 20 years by Bruce R. Reed and Marvin A. Lanphere (both U.S. Geological Survey) as part of their studies of the batholith.
Koeneman, Lisa L.; Wilson, Frederic H. Influenza A virus recovery, diversity, and intercontinental exchange: A multi-year assessment of wild bird sampling at Izembek National Wildlife Refuge, Alaska
Western Alaska is a potential point-of-entry for foreign-origin influenza A viruses (IAVs) into North America via migratory birds. We sampled waterfowl and gulls for IAVs at Izembek National Wildlife Refuge (NWR) in western Alaska, USA, during late summer and autumn months of 2011–2015, to evaluate the abundance and diversity of viruses at this...
Reeves, Andrew B.; Hall, Jeffery S.; Poulson, Rebecca L.; Donnelly, Tyrone F.; Stallknecht, David E.; Ramey, Andrew M. Montane-breeding bird distribution and abundance across national parks of southwestern Alaska
Between 2004 and 2008, biologists conducted an inventory of breeding birds during May–June primarily in montane areas (>100 m above sea level) in Aniakchak National Monument and Preserve (Aniakchak NMP), Katmai National Park and Preserve (Katmai NPP), and Lake Clark National Park and Preserve (Lake Clark NPP) in southwestern Alaska. Observers...
Amundson, Courtney L.; Handel, Colleen M.; Ruthrauff, Daniel R.; Tibbitts, T. Lee; Gill, Robert E. Plasticity in physiological condition of female brown bears across diverse ecosystems
Variation in life history strategies facilitates the near global distribution of mammals by expanding realized niche width. We investigated physiological plasticity in the spring body composition of adult female brown bears (Ursus arctos) across 4 diverse Alaskan ecosystems. Brown bears are a highly intelligent omnivore with a historic range...
Hilderbrand, Grant V.; Gustine, David; Mangipane, Buck A.; Joly, Kyle; Leacock, William; Mangipane, Lindsey; Erlenbach, Joy; Sorum, Mathew; Cameron, Matthew; Belant, Jerrold L.; Cambier, Troy Antibiotic-resistant Escherichia coli in migratory birds inhabiting remote Alaska
We explored the abundance of antibiotic-resistant Escherichia coli among migratory birds at remote sites in Alaska and used a comparative approach to speculate on plausible explanations for differences in detection among species. At a remote island site, we detected antibiotic-resistant E. coli phenotypes in samples collected...
Ramey, Andrew M.; Hernandez, Jorge; Tyrlöv, Veronica; Uher-Koch, Brian D.; Schmutz, Joel A.; Atterby, Clara; Järhult, Josef D.; Bonnedahl, Jonas Lessons learned from research and surveillance directed at highly pathogenic influenza A viruses in wild birds inhabiting North America
Following detections of highly pathogenic (HP) influenza A viruses (IAVs) in wild birds inhabiting East Asia after the turn of the millennium, the intensity of sampling of wild birds for IAVs increased throughout much of North America. The objectives for many research and surveillance efforts were directed towards detecting Eurasian origin HP IAVs...
Ramey, Andrew M.; DeLiberto, Thomas J.; Berhane, Yohannes; Swayne, David E.; Stallknecht, David E. Mineral constraints on arctic caribou (Rangifer tarandus): a spatial and phenological perspective
Arctic caribou (Rangifer tarandus) have the longest terrestrial migration of any ungulate but little is known about the spatial and seasonal variation of minerals in summer forages and the potential impacts of mineral nutrition on the foraging behavior and nutritional condition of arctic caribou. We investigated the phenology, availability, and...
Oster, K. W.; Barboza, P.S.; Gustine, David D.; Joly, Kyle; Shively, R. D. Phylogeny and species traits predict bird detectability
Avian acoustic communication has resulted from evolutionary pressures and ecological constraints. We therefore expect that auditory detectability in birds might be predictable by species traits and phylogenetic relatedness. We evaluated the relationship between phylogeny, species traits, and field‐based estimates of the two processes that...
Solymos, Peter; Matsuoka, Steven M.; Stralberg, Diana; Barker, Nicole K. S.; Bayne, Erin M. Avian predator buffers against variability in marine habitats with flexible foraging behavior
How well seabirds compensate for variability in prey abundance and composition near their breeding colonies influences their distribution and reproductive success. We used tufted puffins (Fratercula cirrhata) as forage fish samplers to study marine food webs from the western Aleutian Islands (53°N, 173°E) to Kodiak Island (57°N, 153°W), Alaska,...
Schoen, Sarah K.; Piatt, John F.; Arimitsu, Mayumi L.; Heflin, Brielle; Madison, Erica N.; Drew, Gary S.; Renner, Martin; Rojek, Nora A.; Douglas, David C.; DeGange, Anthony R. Energetic solutions of Rock Sandpipers to harsh winter conditions rely on prey quality
Rock Sandpipers Calidris ptilocnemis have the most northerly non-breeding distribution of any shorebird in the Pacific Basin (upper Cook Inlet, Alaska; 61°N, 151°W). In terms of freezing temperatures, persistent winds and pervasive ice, this site is the harshest used by shorebirds during winter. We integrated physiological, metabolic,...
Ruthrauff, Daniel R.; Dekinga, Anne; Gill, Robert E.; Piersma, Theunis Volcanic ash deposition, eelgrass beds, and inshore habitat loss from the 1920s to the 1990s at Chignik, Alaska
We quantified the shallowing of the seafloor in five of six bays examined in the Chignik region of the Alaska Peninsula, confirming National Ocean Service observations that 1990s hydrographic surveys were shallower than previous surveys from the 1920s. Castle Bay, Chignik Lagoon, Hook Bay, Kujulik Bay and Mud Bay lost volume as...

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).

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.
