Dictionary of Microsatellite Loci from the U.S. Geological Survey, Alaska Science Center, Molecular Ecology Laboratory Dictionary of Microsatellite Loci from the U.S. Geological Survey, Alaska Science Center, Molecular Ecology Laboratory
This data package provides a dictionary of microsatellite locus primers used by the USGS Alaska Science Center, Molecular Ecology Laboratory (MEL). It is a look-up file of microsatellite locus names and citations to the original publication or source where additional information about the locus primers may be found.
Brant (Branta bernicla) Genetic Data from North America, Europe, and Asia Brant (Branta bernicla) Genetic Data from North America, Europe, and Asia
This data package is comprised of one table with genetic data from Brant (Branta bernicla). Data include sampling location and allele sizes of 14 microsatellite loci.
Harlequin Duck Genetic Data, North America, Greenland, and Iceland, 1952-2001 Harlequin Duck Genetic Data, North America, Greenland, and Iceland, 1952-2001
This data package is comprised of three tables with data from wintering Harlequin Ducks (Histrionicus histrionicus) from Alaska, British Columbia, Washington, Maine, Greenland, and Iceland. The first table contains available allele sizes for 7 microsatellite loci (Sfiµ1, Sfiµ4, Sfiµ9, Sfiµ10, Bcaµ10, Hhiµ2, Hhiµ5) and mtDNA control region haplotypes. The second table contains the mtDNA...
DNA Microsatellite and Sex Identification Marker Screening for Mexican Spotted Owl (Strix occidentalis lucida) DNA Microsatellite and Sex Identification Marker Screening for Mexican Spotted Owl (Strix occidentalis lucida)
Two tables of data are included in this data release. The first table provides screening results for 32 previously described and/or published microsatellites and 1 sexing marker, primer redesigns for use in Mexican Spotted Owls in this data release, and size of markers in Mexican Spotted Owls. The second table provides microsatellite and sexing marker results for 10 tissue and 98 feather...
Gavia Species Identification and Diet Composition from Feces, Central North Slope, Alaska, 2012-2014 Gavia Species Identification and Diet Composition from Feces, Central North Slope, Alaska, 2012-2014
This data set is comprised of one table with sampling information and NCBI BioProject accession numbers for sequence information of this amplicon-based study targeting Loon (Gavia sp.) and fish species expected in lake systems of the North Slope of Alaska from fecal samples. Highly conserved primers which could differentiate species of interest were developed for five portions of gavia...
Detection of Multiple Fish Species Using Environmental DNA (eDNA), Alaska 2018 Detection of Multiple Fish Species Using Environmental DNA (eDNA), Alaska 2018
This release provides results of an environmental DNA (eDNA) study of fish identified in seven Alaskan lakes, three streams, and a positive control. Samples included replicates for multiple sampling dates and locations. The reference list and conserved primer sets to identify species present were developed using publicly available data (https://www.ncbi.nlm.nih.gov/genbank/). Highly...

A phylogeographical study of the discontinuously distributed Harlequin Duck (Histrionicus histrionicus) A phylogeographical study of the discontinuously distributed Harlequin Duck (Histrionicus histrionicus)
Species distributions are often indicative of historical biogeographical events and contemporary spatial biodiversity patterns. The Harlequin Duck Histrionicus histrionicus is a sea duck of conservation concern that has a disjunct distribution, with discrete portions of its range associated with northern Pacific and Atlantic Ocean basins. Movement data indicate migratory connectivity...

Lack of spatial genetic structure among nesting and wintering King Eiders Lack of spatial genetic structure among nesting and wintering King Eiders
The King Eider (Somateria spectabilis) has been delineated into two broadly distributed breeding populations in North America (the western and eastern Arctic) on the basis of banding data and their use of widely separated Pacific and Atlantic wintering areas. Little is known about the level of gene flow between these two populations. Also unknown is whether behavioral patterns common...

Phylogeography of Canada Geese (Branta canadensis) in western North America Phylogeography of Canada Geese (Branta canadensis) in western North America
Using molecular genetic markers that differ in mode of inheritance and rate of evolution, we examined levels and partitioning of genetic variation for seven nominal subspecies (11 breeding populations) of Canada Geese (Branta canadensis) in western North America. Gene trees constructed from mtDNA control region sequence data show that subspecies of Canada Geese do not have distinct mtDNA...

Molecular status of the dusky Canada goose (Branta canadensis occidentalis): A genetic assessment of a translocation effort Molecular status of the dusky Canada goose (Branta canadensis occidentalis): A genetic assessment of a translocation effort
Until recently, the dusky Canada goose (Branta canadensis occidentalis) was managedas one breeding population from the CopperRiver Delta (CRD), Alaska. Population numberson the CRD have declined precipitously over thelast three decades, due in part to changes inhabitat. In 1981, a pair of Canada geese,presumably B.c. occidentalis, wasreported nesting on Middleton Island (MID), inthe Gulf...

Isolation and characterization of microsatellite loci in the intertidal sponge Halichondria panicea Isolation and characterization of microsatellite loci in the intertidal sponge Halichondria panicea
GA- and CA-enriched genomic libraries were constructed for the intertidal sponge Halichondria panicea. Unique repeat motifs identified varied from the expected simple dinucleotide repeats to more complex repeat units. All sequences tended to be highly repetitive but did not necessarily contain the targeted motifs. Seven microsatellite loci were evaluated on sponges from the clone source...

Molecular genetic status of Aleutian Canada Geese from Buldir and the Semidi Islands, Alaska Molecular genetic status of Aleutian Canada Geese from Buldir and the Semidi Islands, Alaska
We conducted genetic analyses of Aleutian Canada Geese (Branta canadensis leucopareia) from Buldir Island in the western Aleutians and the Semidi Islands in the eastern portion of their breeding range. We compared data from seven microsatellite DNA loci and 143 base pairs of the control region of mitochondrial DNA from the two populations of Aleutian Canada Geese and another small-bodied
