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 samples for 11 microsatellite markers identified as variable in initial marker screenings.

This dataset contains count and detection-nondetection data of Barred Owls from 106 historical breeding territories of Northern Spotted Owl territories (i.e. sites) in the Oregon Coast Ranges from 1995 to 2016. Data collected from 1995 to 2014 are partitioned into 2-week periods from 1 March – 31 August each year, totaling 12 possible sampling periods per year. Data collected from 2015 and 2016 are partitioned into 2-month periods from 1 March – 31 August, totaling 3 possible sampling periods each year. This dataset also describes the proportion of total area surveyed per site per sampling period in 2015 and 2016, as well as the proportion of each site with older coniferous forest in each year (1995 – 2016).

The data are included in 8 separate text files. 1) "Sample_coordinates.txt". The file contains sample identifiers along with geographic coordinates associated with each sample. Coordinates are specified as UTM Zone 10 values (WGS84). 2) "Sample_genotypes.txt". The file contains a sample identifier along with microsatellite genotypes associated with each sample. 3) "uniform_conductances.asc". An ASCII text-based representation of a map containing idealized habitat for Northern Spotted Owls. 4) "1870_conductance.asc". An ASCII text-based representation of a map containing idealized habitat for Northern Spotted Owls in the 1870's. 5) "1940_conductance.asc". An ASCII text-based representation of a map containing idealized habitat for Northern Spotted Owls in the 1840's. 6) "1986_conductance.asc". An ASCII text-based representation of a map containing idealized habitat for Northern Spotted Owls in 1986. 7) "1994_conductance.asc". An ASCII text-based representation of a map containing idealized habitat for Northern Spotted Owls in 1994. 8) "2012_conductance.asc". An ASCII text-based representation of a map containing idealized habitat for Northern Spotted Owls in 2012.

This data set contains sampling information, allele sizes of 11 microsatellite loci, and Genbank accession numbers of ddRAD seq results for scoters (Melanitta sp.). Microsatellite data is provided for three North American species of scoter (black scoter, M. americana n = 61; white-winged scoter, M. deglandi, n = 208; surf scoter, M. perspicillata, n = 145) and their European congeners (common scoter, M. nigra, n = 19; velvet scoter, M. fusca, n = 20). Individuals with ddRAD results include 27 black scoters, 4 common scoters, 32 surf scoters, 28 white-winged scoters, and 4 velvet scoters.

This data set contains allele sizes for 30 individuals of 9 previously published and 20 novel microsatellite loci and the molecular sex verification (n = 31) of Emperor Geese (Chen canagica) from various locations across Alaska. The allele sizes for the 20 microsatellite loci developed in this study are included for 10 White-fronted Geese (Anser albifrons) from Selawik, 11 Black Brant (Branta bernicla nigricans) from Kigigak Island, 10 Canada Geese (Branta canadensis) from Copper River Delta, and 9 Cackling Geese (Branta hutchinsii) from lower Kashunuk River (Hock Slough) and Tutakoke River.
