Molecular, morphological, and distributional data supporting the recognition of an undescribed freshwater mussel endemic to the Edwards Plateau in the Colorado River basin Molecular, morphological, and distributional data supporting the recognition of an undescribed freshwater mussel endemic to the Edwards Plateau in the Colorado River basin

The widespread distribution of Strophitus undulatus, as well as high intraspecific morphological variation, has led previous authors to doubt the taxon is representative of a single species. Here we provide detailed information for all the freshwater mussels and associated DNA sequence data utilized to test species boundaries in S. undulatus. These molecular data, in combination with...

Molecular-scale speciation of germanium and copper within sphalerite from Central Tennessee mining district (TN), Red Dog mining district (AK), and Metaline mining district (WA) Molecular-scale speciation of germanium and copper within sphalerite from Central Tennessee mining district (TN), Red Dog mining district (AK), and Metaline mining district (WA)

Oxidation state and bonding environment of Ge and Cu in ZnS and Zn mineral concentrates from a variety of sources [Central Tennessee mining district (TN), Metaline mining district, (WA), and Red Dog mine (AK)] were determined by linear combination fits from x-ray absorption spectroscopy (XAS) analysis. Sphalerites from the East Tennessee mining district contained Ge in concentrations...

Moloka'i, Hawai'i rapid assessment of hydrology, soils, and vegetation in coastal wetlands 2022 Moloka'i, Hawai'i rapid assessment of hydrology, soils, and vegetation in coastal wetlands 2022

In this project, we assessed the potential for twelve coastal wetland sites on the island of Molokaʻi, Hawaiʻi, to provide socio-cultural resources and habitat for flora and fauna following restoration. In April 2022, a rapid field assessment of hydrology, soils, and vegetation was carried out at each of the wetland sites. The data provided here were collected in order to inform a...

Monitoring Data to Support the Operation of the Electric Dispersal Barrier System on the Chicago Sanitary and Ship Canal at Romeoville, Illinois, October 1, 2019, to September 30, 2020 Monitoring Data to Support the Operation of the Electric Dispersal Barrier System on the Chicago Sanitary and Ship Canal at Romeoville, Illinois, October 1, 2019, to September 30, 2020

The U.S. Geological Survey (USGS) monitors water surface flow reversals, commercial vessel traffic, and temperature and specific conductance in the U.S. Army Corps of Engineers Electric Dispersal Barrier System (EDBS) on the Chicago Sanitary and Ship Canal, Chicago, Illinois. These data are planned to be released on USGS ScienceBase annually. This data release is the summary of all the...

Monthly crop irrigation withdrawals and efficiencies by HUC12 watershed for years 2000-2020 within the conterminous United States (ver. 2.0, September 2024) Monthly crop irrigation withdrawals and efficiencies by HUC12 watershed for years 2000-2020 within the conterminous United States (ver. 2.0, September 2024)

The USGS has published United States water-use data every five years since 1950. To increase the temporal and spatial availability of water use estimates using nationally consistent methods, the USGS is developing national water-use models for each major water-use category. This data release publishes crop irrigation withdrawals for the conterminous United States (CONUS) that are...

Monthly inorganic nitrogen atmospheric wet deposition estimates for the conterminous United States, 1999 through 2020 Monthly inorganic nitrogen atmospheric wet deposition estimates for the conterminous United States, 1999 through 2020

This data release provides estimates of monthly wet atmospheric deposition of total inorganic nitrogen (TIN)--the summation of nitrate (NO3) and ammonium (NH4) ions--for the conterminous United States from 1999 through 2020 in units of kilograms nitrogen per square kilometer per month with spatial reference ESPG 4326. The spatial resolution of the gridded data provided in this release is

Monthly Satellite-Estimated Precipitation Reports for the Republic of the Marshall Islands (ver. 2.1, January 2025) Monthly Satellite-Estimated Precipitation Reports for the Republic of the Marshall Islands (ver. 2.1, January 2025)

The Republic of the Marshall Islands (RMI) is a nation of more than thirty low-lying atolls and islands, most of which are inhabited, dispersed across an Exclusive Economic Zone (EEZ) over 770,000 square miles in the tropical central North Pacific Ocean. Monitoring environmental conditions for potential drought risk is challenging in such a dispersed Island nation, and current drought...

Morpholine Imprinted Atlantic Salmon Behavioral and Morphometric Data, 2018-2022 Morpholine Imprinted Atlantic Salmon Behavioral and Morphometric Data, 2018-2022

Subadult and smolt behavioral data were compiled by Ali Mokdad from Trevor Pitcher's lab at the University of Windsor, Ontario, Canada. Data are comprised of fish reactions in choice flume video data (attractance/avoidance) collected by Jeremy Kraus at Tunison Lab of Aquatic Science, August 2021 and February 2020 respectively. Atlantic salmon were exposed/not exposed to imprinting...

Morphometric measurements from unionid Pondmussel (Ligumia subrostrata) and concentrations of four per- and polyfluoroalkyl substances (PFAS) in water and mussels collected from a 14-day accumulation and 7-day elimination study Morphometric measurements from unionid Pondmussel (Ligumia subrostrata) and concentrations of four per- and polyfluoroalkyl substances (PFAS) in water and mussels collected from a 14-day accumulation and 7-day elimination study

Dataset consists of morphometric measurements from unionid Pondmussel (Ligumia subrostrata) and concentrations of four per- and polyfluoroalkyl substances (PFAS) in water and freshwater mussels collected from a 14-day accumulation and 7-day elimination study. The accumulation of four per- and polyfluoroalkyl substances (PFAS) were measured. Samples (4 replicates) were collected at 0, 4...

Mortality, morphology, and water chemistry for 6PPD-quinone exposed coho embryos Mortality, morphology, and water chemistry for 6PPD-quinone exposed coho embryos

Understanding evolutionary processes that drive population dynamics is critical in ecology. Measuring the performance-density relationship in long-lived mammalian species demands long-term data, limiting the ability to observe such mechanisms. We tested density-dependent (intrinsic) and density-independent (extrinsic) drivers of body composition of grizzly bears (Ursus arctos) in the...

Motility of sperm from adult largemouth bass pond exposure to 17 alpha-ethinylestradiol or estrone-atrazine mixture (2018) Motility of sperm from adult largemouth bass pond exposure to 17 alpha-ethinylestradiol or estrone-atrazine mixture (2018)

Adult largemouth bass have been shown to be sensitive to induction of intersex in response to chronic estrogen exposures over a complete reproductive cycle. Late summer to fall is the period of early gonad recrudescence when spermatogenesis is beginning in preparation for the spawning season in the spring. Our objective was to assess in 2018 whether early gonad recrudescence was a period...

Mountain Plover population and habitat assessments in Texas, 2019–2020 Mountain Plover population and habitat assessments in Texas, 2019–2020

We conducted population and habitat assessments for Mountain Plovers in Texas during winters of 2019 and 2020. We used roadside surveys and distance-sampling to estimate bird density and calculate population totals for the study area, which included parts of five ecoregions (Chihuahuan Deserts, High Plains, Central Great Plains, Southern Texas Plains, Texas Blackland Prairies, and...
