Sample collection information, single nucleotide polymorphism, and microsatellite data for white-tailed ptarmigan across the species range generated in the Molecular Ecology Lab during 2016
This data release comprises a dataset that contains sample collection information and microsatellite genotypes, and another dataset that contains single nucleotide polymorphism (SNP) genotypes with sample collection information for populations of white-tailed ptarmigan across the species' range. There is also an additional file (accession numbers.xlsx) linking samples to accession numbers in Genbank. This data was collected in order to address the following: The delineation of intraspecific units that are evolutionarily and demographically distinct is an important step in the development of species-specific management plans. Neutral genetic variation has served as the primary data source for delineating units for...
Greater Sage-grouse microsatellite data from across the species range in western North America between 1992 and 2015
Greater Sage-grouse were sampled for genetic analysis with the goal of quantifying genetic structure and gene flow across the entire species range in the U.S. and Canada. Data presented here consist of two data sets both including genetic data from 15 microsatellite markers. Most samples were collected between 2005 and 2015 (feathers collected non-invasively off the ground) yet some samples were blood samples collected as part of telemetry studies. The samples from Washington were collected much earlier beginning in 1992. The first data set (GRSG_data_dups_full_lek_alias.csv) is the full data consisting of 6,725 individuals. The second data set (GRSG_data_dups_thinned_lek_alias.csv) includes a subset of the full...
To understand the genetic structure of six rare plant species (Acanthomintha ilicifolia, Baccharis vanessae, Chloropyron maritimum ssp. maritimus, Deinandra conjugens, Dicranostegia orcuttiana, Monardella viminea), we obtained samples from known occurrences in San Diego County, prepared and sequenced ddRAD genomic libraries, and developed and analyzed a panel of genetic markers to assess population diversity and divergence. We provide this SNP genotype dataset in Structure format, produced in Stacks v2.0b8, for future monitoring efforts and population genetic analysis. These data support the following publication: Milano, E.R., and Vandergast, A.G., 2018, Population genomic surveys for six rare plant species in...
Fish community assessment using environmental DNA metabarcoding data after an invasive species eradication and native restocking effort in Pinecrest Gardens, FL in 2017-18
Reported here are the metabarcoding read numbers and biomass data assessed from a fish community in a southern Florida pond in Pinecrest Gardens after invasive species eradication and native restocking in 2017 and 2018 in linear regression models. This dataframe contains the number of fish of each species identified, their measured lengths estimated population surface area, and the number of metabarcoding reads (with SD and COV) for each species observed from the sampling date.
In 2007, a phase shift from corals to corallimorpharians (CM) was documented at Palmyra Atoll, Line Islands, centered around a shipwreck. Subsequent surveys revealed CM to be overgrowing the reef benthos, including corals and coralline algae, potentially placing coral ecosystems in the atoll at risk. This prompted the U.S. Fish and Wildlife Service, the lead management agency of the atoll, to remove the shipwreck. Subsequent surveys showed reversal of spread of CM around the ship impact site. We explain patterns of spread of the CM in terms of life history and local currents and show with a pilot study that pulverized bleach may be an effective tool to eradicate CM on a local scale. If applied strategically, particularly...
Effects of fungal endophytes on invasive Phragmites australis (ssp. australis) performance in growth chamber and field experiments
These data tables contain data collections from field experiments of Phragmites australis (ssp. australis) treated with known fungal endophytes. Tiller counts, tiller diameter, and tiller height measurements were taken every two weeks over an eight-week study period. Clones of Phragmites plants were collected from three different locations: Sandusky, Michigan; Bloomington, Indiana; and the Ottawa National Wildlife Refuge near Oak Harbor, Ohio. Additionally, data collections from a similar experiment of Phragmites australis (ssp. australis) treated with known fungal endophytes performed in a growth chamber are included. Tiller numbers and tiller heights were measured every three weeks over 15 total weeks for the...
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.
This includes all detection events of black bears that were genotyped from sampling that occurred in 2004.
These data show the multilocus genotypes, gender, and midline carapace length (MCL) for desert tortoises (Gopherus agassizii) sampled in the central portion of the Mojave desert tortoise range. This data supports the following publication: Dutcher, K.E., Vandergast, A.G., Esque, T.C., Mitelberg, A., Matocq, M.D., Heaton, J.S. and Nussear, K.E., Genes in space: what Mojave Desert tortoise genetics can tell us about landscape connectivity. Conservation Genetics, pp.1-15.
Long-term environmental management to prevent waterfowl population declines is informed by ecology, movement behavior and habitat use patterns. Extrinsic factors such as human-induced disturbance can cause behavioral changes which may influence movement, and resource needs, driving variation that affects management efficacy. To better understand the relationship between human-based disturbance and animal movement and habitat use, and their potential effects on management, we GPS tracked 15 dabbling ducks in California over about 4-weeks before, during and after the start of a recreational hunting season in October and November 2018. We recorded locations at 2-minute intervals across three separate 24-hour tracking...

Developmental Stages of Grass Carp (Ctenopharyngodon idella) eggs in the Sandusky River (ver. 3.0, July 2020)
Grass Carp Ctenopharyngodon idella was imported to the United States in the 1960s for research into its usefulness as a biocontrol agent for nuisance aquatic vegetation. Escapees and intentionally stocked individuals founded wild, spawning populations in the Mississippi River and tributaries to the Laurentian Great Lakes. USGS-led research on the Sandusky River, a tributary to Lake Erie, demonstrated spawning of Grass Carp in 2015. In 2018, sampling with ichthyoplankton nets in the Sandusky River 11-13 June produced thousands of suspected fertilized Grass Carp eggs. Genetic analysis of 49 eggs identified by microscopic analysis as Grass Carp eggs confirmed all were from Grass Carp, demonstrating 100% accuracy of...
Files containing detection events from genetic sampling sites associated with the unique identifier of American black bears in Glacier National Park, Montana, USA, 2004.
Between 2004 and 2011 bighorn sheep were darted in Glacier National Park and in Dinosaur National Monument. Blood was drawn. These are the genotypes resulting from an Ovine HD array from the bighorns. The first 3 columns refers to bighorn sheep identifiers: 'Herd_Unit', 'IndID', and 'AgencyID'. IndID is the identifier assigned at Montana State University. Subsequent columns each represent a locus, with the values in the locus representing the allele.
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.
