Plasmodium Parasite Infection Data from Mosquitoes Collected in South-central Alaska, 2016 Plasmodium Parasite Infection Data from Mosquitoes Collected in South-central Alaska, 2016
This data set includes two tables associated with a study of Plasmodium parasite infection in mosquitoes collected in south-central Alaska during the summer of 2016. The first table contains data regarding mosquito collection from three sites using CO2 baited CDC light traps. Mosquitoes were sorted and pooled according to collection date, genus, and location and subsequently screened for
Blood Parasite Infection Data from Northwestern Crows (Corvus caurinus), Alaska, 2007-2008 Blood Parasite Infection Data from Northwestern Crows (Corvus caurinus), Alaska, 2007-2008
This data set consists of two tables associated with a study of Haemosporidian parasite infection in Northwestern Crows (Corvus caurinus) sampled at six locations throughout southcentral and southeast Alaska in 2007-2008. The first table contains species, location, banding, and morphometric data for all samples. The second table contains results from heamosporidian parasite screening of...
Sampling, Antimicrobial Resistance Testing, and Genomic Typing of Carbapenemase Producing E. coli in Gulls (Larus spp.) in Alaska, 2016 Sampling, Antimicrobial Resistance Testing, and Genomic Typing of Carbapenemase Producing E. coli in Gulls (Larus spp.) in Alaska, 2016
This data set includes information on collections of fecal samples from wild gulls (Larus spp.) at seven locations in Alaska, USA. Samples were screened for carbapenemase producing Escherichia coli (E. coli) and tested for resistance to multiple antibiotics.
Influenza A Virus Data from Emperor Geese, Alaska Influenza A Virus Data from Emperor Geese, Alaska
Data set containing avian influenza A virus (IAV) sampling information for Emperor Geese in Alaska, 2015-2017. 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...
