We investigated fine-scale genetic patterns of the federally threatened Eastern Massasauga Rattlesnake (Sistrurus catenatus) on a relatively undisturbed island in northern Michigan, USA. This species often persists in habitat islands throughout much of its distribution due to extensive habitat loss and distance-limited dispersal. These data are from 102 individual Eastern Massasauga Rattlesnakes sampled at Bois Blanc Island, Michigan and genotyped at 15 microsatellite loci. Samples were collected as part of a study to examine functional connectivity for the Eastern Massasauga. We found that the entire island population exhibited weak genetic structuring with spatially segregated variation in effective migration...
Data represent locations of mares and stallions in Utah. Data were collected using GPS radio collars on mares or tail transmitters braided into the tails of stallions, at a 2-hour fix rate for a period spanning 2016 to 2020. Horses were located at Conger Herd Management Area (HMA) or Frisco HMA in the Great Basin ecosystem of Utah, USA.

Eight-minute point-transect distance bird surveys were collected in and around Haleakala National Park from 1993-2008. This dataset contains the location, species, and distance to detected birds, as well as identifying initials to distinguish among observers.

To determine the potential for controlling non-native Phragmites australis through use of a cut-to-drown management strategy we performed a controlled greenhouse mesocosm experiment in Ann Arbor, MI during summer 2021. Field collected Phragmites rhizomes from one site within Michigan were propagated, cuttings taken of individual stems and potted in nursery pots. Established plants were then subjected to a complete factorial combination of three submergence treatments (no submergence, partial submergence of aboveground tissues, and compete submergence of aboveground tissues) and 3 cutting treatments (no cutting, spring cutting of above ground tissues, and summer cutting of aboveground tissues). By performing weekly...

Collection of microsatellite genetic data from multiple projects involving southern mule deer (Odocoileus hemionus fuliginatus) in San Diego County, California. Samples were collected 2005-2007, 2010, 2012-2013, 2015, and 2018-2020. These data support the following publication: Mitelberg, A., Smith, J.G., and Vandergast, A.G., 2019, DNA Fingerprinting of Southern mule deer (Odocoileus hemionus fuliginatus) in north San Diego County, California (2018–19): U.S. Geological Survey Open-File Report 2019–1138, 25 p., https://doi.org/10.3133/ofr20191138.

Prior to removal of pest species from an area, resource managers must determine if re-immigration from another population is possible. Voles inhabiting Saddle Rock on the southern Oregon coast are suspected to be partially responsible for declines in the Leach's storm petrel colony on the island. The island is very close to the mainland, and it is potentially accessible during below-average low tides. USGS scientists Mark Miller and Susan Haig and colleagues used genetic techniques to assess island vole population connectivity.

The federally endangered Cape Sable seaside sparrow (Ammospiza maritima mirabilis) is endemic to the Greater Everglades ecosystem in southern Florida. The subspecies inhabits the fragmented freshwater marl prairies and contains six subpopulations (A-F), named for management purposes, since genetic information is lacking. To evaluate genetic connectivity and inform management decisions, feather samples were collected between 2011 and 2018 from 108 sparrows across five subpopulations (A-E). Sequence data for four mitochondrial DNA markers (N = 36–69) and 12 nuclear microsatellite loci (N = 55) are provided. The mitochondrial markers used were Cytochrome b (Cytb), control region D-loop, NADH dehydrogenase 2 (ND2),...
This data release provides avian data for 11 songbird species (Bewick’s wren [Thryomanes bewickii], black-throated gray warbler [Setophaga nigrescens], Brewer’s sparrow [Spizella breweri], gray flycatcher [Empidonax wrightii], gray vireo [Vireo vicinior], green-tailed towhee [Pipilo chlorurus], juniper titmouse [Baeolophus ridgwayi], loggerhead shrike [Lanius ludovicianus], sagebrush sparrow [Artemisiospiza nevadensis], sage thrasher [Oreoscoptes montanus], and Townsend’s solitaire [Myadestes townsendi]) associated with summertime point count surveys conducted throughout the InterMountain West under the Integrated Monitoring in Bird Conservation Regions (IMBCR) program, 2008 - 2020. Additionally, remotely sensed...
Point count survey data collected from 1998 through 2018 to estimate palila abundance on Mauna Kea. Point counts were conducted on 32 transects surrounding Mauna Kea volcano on Hawaii Island. Transects extended from roughly treeline through the forested area, with survey stations approximately 150 m apart. Counts were conducted for six minutes, during which the species, distance to, and detection type were recorded for all birds observed. First posted: December 6, 2018 (Version unavailable since it contains sensitive information. All non-sensitive data is contained in version 2.0).

Conservation translocations are a common wildlife management tool that can be difficult to implement and evaluate for effectiveness. Genetic information can provide unique insight regarding local impact of translocations (e.g., presence and retention of introduced genetic variation) and identifying suitable source and recipient populations (e.g., adaptive similarity). We developed two genetic data sets and wrote statistical code to evaluate conservation translocation effectiveness into the isolated northwestern region of the greater sage-grouse (Centrocercus urophasianus) distribution and to retrospectively evaluate adaptive divergence among source and recipient populations. Our first data set was microsatellite-based...
