Data

This dataset consists of one table containing whole-rock geochemistry data for 251 igneous, metamorphic, and mineralized (metasomatic) rocks from various locations across Alaska in support of mineral assessments of critical minerals and transboundary watersheds. The samples were collected mainly between 2019 and 2023, and all materials were analyzed by ALS Global, between 2019 and 2023...

This data package contains 1) field data and 2) predicted distributions of three species of boreal-nesting birds in interior Alaska: Lesser Yellowlegs (Tringa flavipes), Olive-sided Flycatcher (Contopus cooperi), and Rusty Blackbird (Euphagus carolinus). The data are compiled from several monitoring programs: Alaska Landbird Monitoring Survey, Alaska Off-road Point-count Program, Susitna...

This data release contains one table with gene transcription results from muscle samples collected from fish occupying freshwater in various Alaskan watersheds. Heat shock protein 70 (HSP70) results from fish included in this data release are published in a separate data release available at https://doi.org/10.5066/P13ZYKWR.

This data release includes one table of nuclear microsatellite genotypes and mitochondrial DNA haplotypes from the cytochrome b region in King Eider. This information was used to determine levels of population genetic differentiation among breeding and wintering sites of King Eiders (Somateria fischeri).

These data are in four tables relating to complete blood count (CBC), biochemistry, blood gas analysis, corticosterone, serum protein electrophoresis, and sample attribute data of adult Pacific (Gavia pacifica) and Red-throated Loons (G. stellata) breeding in northern Alaska in 2023.

These data are in one table relating to the selenium concentration (μg/g) in whole blood of adult female emperor geese (Anser canagicus) sampled on the Yukon-Kuskokwim Delta, Alaska in June 2017.

This data set provides polar bear microsatellite genotypes derived from twenty loci (CPH9, CXX20, CXX110, CXX173, G1A, G10B, G10C, G1D, G10H, G10J, G10L, G10M, G10P, G10U, G10X, MU50, MU51, MU59, MSUT2, 145P07). Blood, buccal swab, skin, and hair samples for microsatellite genetic analysis were collected from polar bears from the Southern Beaufort Sea between 1981 and 2023. Blood, buccal...

This dataset provides sample data and NCBI accession information for genomic sequencing of Gray-headed Chickadee and Boreal Chickadee from North America and Russia.

This data release contains one table of genetic data (mitochondrial haplotypes and nuclear microsatellite genotypes) used to evaluate utility of two morphological measures (culmen length and plumage color) to correctly identify groups of hunter-harvested dusky (Branta canadensis occidentalis) and dusky-like Canada geese on wintering grounds within the Pacific Flyway of North America...

This data set provides polar bear (Ursus maritimus) microsatellite genotypes derived from 21 loci (CPH9, CXX20, CXX110, CXX173, G1A, G10B, G10C, G1D, G10H, G10J, G10L, G10M, G10P, G10U, G10X, Mu26, Mu50, Mu51, Mu59, MSUT-2, REN145P07). Blood serum and hair samples for microsatellite genetic analysis were collected from polar bears from the Chukchi Sea between 1986 and 2019. Serum samples...

This dataset contains U-Pb isotopic data and associated ages of zircons within the lithologic framework of igneous, metaigneous, and metasedimentary rocks collected from the Seldovia quadrangle in southcentral Alaska. The samples were collected as part of geological mapping and research conducted from 2020 to 2023 and funded by the Mineral Resources Program of the U.S. Geological Survey...

This dataset is one table with results of tests to determine exposure of Chukchi Sea polar bears to a suite of pathogens. Results are serological tests for antibodies and tests of fecal samples for presence of parasites. Serologic assays were conducted for Toxoplasma gondii, Neospora caninum, Francisella tularensis, Coxiella burnetii, Leptospira spp., Brucella canis, Brucella abortus...
