We provide genetic and distribution data for the Louisiana Pigtoe, Pleurobema riddellii, to guide decisions related to federal protection for the species under the U.S. Endangered Species Act. Our final dataset includes 125 COI sequences generated as part of our study representing P. riddellii from eight North American river basins. This includes the COI sequence we generated from a museum specimen collected from the Trinity River in the late 1900s, which is the first genetic confirmation of P. riddellii in the Trinity River basin. Also included are sequences from specimens initially identified as Fusconaia cerina (n=3) Fusconaia flava (n=1), Fusconaia sp. (n=5), Pleurobema sintoxia (n=10), and Pustulosa pustulosa (n=1) that were genetically confirmed to be P. riddellii. Additionally, we provide distribution data from freshwater mussel surveys, museum records, and field notes representing 467 records of P. riddellii collected from pre-1900 - 2022. The occurrence data includes records from 9 river basins (Amite, Calcasieu, Neches, Ouachita, Pearl, Red, Sabine, San Jacinto, Trinity), 54 HUC-10 watersheds, and 5 states (Arkansas, Louisiana, Mississippi, Oklahoma, Texas).

We present a tabular data set representing values used to evaluate hypotheses of breeding habitat selection for immigrants and returning Northern Great Plains piping plovers (Charadrius melodus) from 2014 – 2019. The associated manuscript uses network analysis approach to evaluate five hypotheses of habitat selection. In this approach breeding locations were nodes and successive year breeding attempts form the edges (immigration) and self-loops (fidelity). Included in the dataset are covariates of habitat amount, conspecific density, and habitat quality, as well as other fields used in the analysis. In addition, we include descriptive breeding location-specific metrics from the network graphs.

These data were compiled to investigate the evolutionary history of Graham's beardtongue (Penstemon grahamii). Objective(s) of our study were to determine the evolutionary history of P. grahamii, including ancestral population sizes, the history of population divergences, and historical connectivity. In addition, we characterized population structure, genetic diversity summary statistics, and landscape factors influencing differentiation. These data represent anonymous loci sequenced from throughout the P. grahamii genome (specifically, .vcf and .structure files). Data in these files were manipulated to represent site frequency spectra between population pairs (.data files). These data were collected in 2019 from across the P. grahamii distribution, which is located in northeastern Utah and western Colorado. Specifically, plants are located at lower elevations on the northern slope of the Book Cliffs, which forms the southern side of the Uinta Basin. These data were collected by employees of the U.S. Geological Survey. Known occurrences of P. grahamii were visited and leaf samples from individual plants were collected from across the species’ distribution. These data can be used to further investigate the genetic differentiation, genetic diversity, and evolutionary history of P. grahamii.

These data were compiled to provide land-management relevant information on the native and nonnative subspecies (subsp.) of Phragmites australis (subsp. americanus and subsp. australis, respectively) in Glen Canyon National Recreation Area (NRA), Grand Canyon National Park (NP), Arches National Park, and Bill Williams National Wildlife Refuge. Specifically, the goals of this work were to determine the extent and distribution of Phragmites australis subspecies in the Glen and Grand Canyon regions, evaluate if P.a. subsp. americanus can be reliably distinguished from P.a. subsp. australis using morphological characters in this region, and determine if P.a. subsp. americanus exhibits genetic structure in the study area. The objectives of our study were to determine how prevalent the nonnative Phragmites is in the study area and support native plant material development for restoration activities in Glen Canyon NRA and Grand Canyon NP. These data represent real-time PCR cycle threshold values (Ct scores) for two target regions, nuclear microsatellite data for seven loci, and morphological data. These data were collected for 84 sites including five nonnative Phragmites locations and 79 native Phragmites locations. Tissue samples were mostly collected along the Colorado River between Glen Canyon Dam and Lake Mead, around Lake Powell, and in tributaries to the Colorado River from 2021 through 2024. Tissue samples and herbarium collections were collected from one to fifteen ramets across each stand, where multiple samples from one stand were spread across its full area. Reference samples for both the native and nonnative Phragmites, Phragmites australis subsp. berlandieri, and a hybrid of P.a. australis and P.a. americanus were acquired and included in analyses. Samples were dried and total genomic DNA was extracted using Qiagen DNeasy Plant MiniKits. Real-time polymerase chain reactions (PCR) with two target regions, AMER and AMAU, were used to identify nonnative Phragmites individuals (Lindsay et al, 2023). We then amplified 7 microsatellite loci (Saltonstall, 2003; Meyerson and others, 2010) using PCR and analyzed the fragments on an ABI 3730XL Genetic Analyzer with GeneScan LIZ500 internal size standard. Although P. australis is polyploid, these loci all had no more than two alleles, so were treated as diploid data. We then collected field and lab data on morphological characters for the stands we genetically tested, following previously described diagnostic characters (Swearington and Saltonstall, 2012; McTavish et al, 2023) These data can be used to evaluate if a stand of Phragmites is nonnative, native, or a hybrid of the two. It can also be used to determine genetic diversity and structure across the sampled stands. Finally, they can be used to assess morphological variability in native Phragmites stands across the region.

This dataset contains single nucleotide polymorphism (SNP) information for aquatic insect species collected in tributaries of the Colorado River in Grand Canyon (Arizona, USA), as well as SNP information for individuals collected from reference reaches of the Upper Colorado River Basin in Utah. This dataset focuses specifically on three species that were common and widely distributed throughout tributary streams in Grand Canyon: a mayfly (Fallceon quilleri), a caddisfly (Hydrospyche oslari), and a water strider (Rhagovelia distincta).
