The data are in three tables: 1) collection data and IAV screening results from fecal samples at several sites in southwestern Alaska, 2) results of blocking enzyme-linked immunosorbent assay (bELISA) tests for IAV antibodies in blood serum collected from nesting female Emperor...
Development of Single Nucleotide Polymorphisms (SNPs) in Greater-White Fronted Geese (Anser albifrons) for genetic stock identification on wintering grounds, 2019 Development of Single Nucleotide Polymorphisms (SNPs) in Greater-White Fronted Geese (Anser albifrons) for genetic stock identification on wintering grounds, 2019
This data set contains a description of 3 mitochondrial DNA and 93 nuclear DNA Single Nucleotide Polymorphism (SNP) loci and sequence information developed through double digest restriction-site associated DNA sequencing (ddRADseq) techniques for Greater White-Fronted Goose (Anser albifrons) that winter in California.
Influenza A antibodies in Pacific (Gavia pacifica), Red-throated (G. stellata), and Yellow-billed Loons (G. adamsii) in Alaska, 2008-2017 Influenza A antibodies in Pacific (Gavia pacifica), Red-throated (G. stellata), and Yellow-billed Loons (G. adamsii) in Alaska, 2008-2017
This data set contains three spreadsheets with results of Influenza A Virus (IAV) screening in blood from Pacific, Red-throated, and Yellow-billed Loons at three locations in Alaska. Loons were captured along the Beaufort Sea Coast, Chukchi Sea Coast, and Yukon-Kuskokwim Delta from 2008-2017. Three different tests were used and the results are presented in separate spreadsheets. All...
Sequence Information from the Mitogenome and Ten Nuclear Genes from Martes Species (Martes americana, M. caurina) of North America, 1972-2010 Sequence Information from the Mitogenome and Ten Nuclear Genes from Martes Species (Martes americana, M. caurina) of North America, 1972-2010
This data set contains individual museum catalog numbers, associated Genbank accession numbers, and species designations based on the mitochondrial genome and ten nuclear loci for 55 Martes americana, 28 Martes caurina, 2 Martes of uncertain taxonomic designation based on genetic data alone, and one each of Martes zibellina, M. pennanti, Gulo gulo, Neovison vison, and Mustela frenata.
Sampling, Antimicrobial Resistance Testing, and Genomic Typing of E. coli in Gulls (Larus spp.) on the Kenai Peninsula, Alaska, 2016 Sampling, Antimicrobial Resistance Testing, and Genomic Typing of E. coli in Gulls (Larus spp.) on the Kenai Peninsula, Alaska, 2016
This data set includes information on collections of fecal or cloacal samples from wild gulls (Larus spp.) at four locations on the Kenai Peninsula, Alaska, USA. Samples were also collected from sockeye salmon harvested as part of the personal-use fisheries on the Kenai and Kasilof Rivers. Samples were screened for Escherichia coli (E. coli) and tested for resistance to multiple...
