The allele sizes for the 12 microsatellite loci developed in this study are included for two populations of Sea Sandwort (Fossil Beach, Kodiak and Egg Bay, Atka) and one...

Antibiotic-resistant Escherichia coli in migratory birds inhabiting remote Alaska, 2015 Antibiotic-resistant Escherichia coli in migratory birds inhabiting remote Alaska, 2015

This data set includes information on collections of fecal or cloacal samples from wild birds at two locations in Alaska, USA. Samples were screened or Escherichia coli (E. coli) and tested for resistance to multiple antibiotics using a variety of methods.

Data for Montane-breeding Bird Distribution and Abundance across National Parks of Southwestern Alaska, 2004-2008 Data for Montane-breeding Bird Distribution and Abundance across National Parks of Southwestern Alaska, 2004-2008

Observation data and model covariate data from breeding bird inventory conducted during May-June 2004 and 2008 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 conducted 1,021 point...

Satellite Telemetry Data for Greater White-fronted Geese (Anser albifrons) Captured on the Arctic Coastal Plain of Alaska, 2013-2017 Satellite Telemetry Data for Greater White-fronted Geese (Anser albifrons) Captured on the Arctic Coastal Plain of Alaska, 2013-2017

This data release contains one table of data from a four-year study of Greater White-fronted Goose (Anser albifrons frontalis) breeding ecology conducted in the National Petroleum Reserve - Alaska during 2013-2017. Location data depict habitat use of 5 marked female birds throughout the annual cycle.

Data for Evaluating Efficacy of 1- versus 2-prong Radio Transmitter Attachment for Scoters in Alaska and Washington, 2008-2010 Data for Evaluating Efficacy of 1- versus 2-prong Radio Transmitter Attachment for Scoters in Alaska and Washington, 2008-2010

A major challenge of wildlife telemetry is choosing an attachment technique that maximizes transmitter retention while minimizing negative side effects. For waterbirds, attachment of transmitters with subcutaneous anchors has been an effective and well-established technique, having been used on >40 species. This method was recently modified to include a second subcutaneous anchor...

Appendices for Transgressive-Regressive Cycles in the Metalliferous, Oil Shale-Bearing Heath Formation (Upper Mississippian), Central Montana Appendices for Transgressive-Regressive Cycles in the Metalliferous, Oil Shale-Bearing Heath Formation (Upper Mississippian), Central Montana

This data release is teh set of appendices for Dumoulin et al. 2018 https://doi.org/10.29041/strat.14.1-4.97-122 ("Transgressive-regressive cycles in the metalliferous, oil shale-bearing Heath Formation (Upper Mississippian), central Montana"). The dataset consists of 8 appendices, including a histogram of solid bitumen and vitrinite Ro values, gas chromatograms, isotopic data, organic...

Marine Bird and Mammal Survey Data from Kachemak Bay, Katmai National Park and Preserve, and Kenai Fjords National Park Marine Bird and Mammal Survey Data from Kachemak Bay, Katmai National Park and Preserve, and Kenai Fjords National Park

These data are part of the Gulf Watch Alaska (GWA) long term monitoring program, nearshore monitoring component. The dataset is a series of comma separated files exported from a survey software program (DLog, Ford Consulting, Portland, OR). The data consists of date, time, latitude, longitude, species abbreviation, count, and behavior. Each year the observers attempt to sample the same...

Denning Behavior Classifications Using Temperature Sensor Data on Collars Deployed on Polar Bears in the Southern Beaufort Sea, 1986-2013 Denning Behavior Classifications Using Temperature Sensor Data on Collars Deployed on Polar Bears in the Southern Beaufort Sea, 1986-2013

These data include two tables. The first is average daily temperatures received via satellite transmitting collars deployed on polar bears in the southern Beaufort Sea 1986-2013. The second is denning classifications for adult female polar bears in the southern Beaufort Sea using the temperature data. Denning was classified using a control chart-based algorithm applied to the temperature...

Walrus Haulout and In-water Activity Levels Relative to Sea Ice Availability in the Chukchi Sea, 2008-2014 Walrus Haulout and In-water Activity Levels Relative to Sea Ice Availability in the Chukchi Sea, 2008-2014

An animal's energetic costs are dependent on the amount of time it allocates to various behavioral activities. For Arctic pinnipeds, the time allocated to active and resting behaviors could change with future reductions in sea ice cover and longer periods of open water. The Pacific walrus (Odobenus rosmarus divergens) is a large Arctic pinniped that rests on sea ice or land between...

Influenza A Viruses and Antibody Response in High-Latitude Urban Wintering Mallards (Anas platyrhynchos), Alaska, 2012-2015 Influenza A Viruses and Antibody Response in High-Latitude Urban Wintering Mallards (Anas platyrhynchos), Alaska, 2012-2015
