Molecular data and results needed to better understand codiversification of freshwater mussels (Unionidae: Quadrulini) and their parasitic larval hosts Molecular data and results needed to better understand codiversification of freshwater mussels (Unionidae: Quadrulini) and their parasitic larval hosts
The North American freshwater mussel tribe Quadrulini has a suite of life history adaptations, however, the evolution of life histories in this group has yet to be explored using comparative phylogenetic methods. Here we provide the AHE DNA sequence alignment representing 27 species from the subfamily Ambleminae that was used to estimate a phylogenomic reconstruction of Quadrulini...
Channel geometry for upstream and downstream cross sections at selected bridge sites in Montana, 2022 Channel geometry for upstream and downstream cross sections at selected bridge sites in Montana, 2022
The U.S. Geological Survey, in cooperation with the Montana Department of Transportation (MDT), collected cross-section data on the upstream and downstream sides at 18 sites involving 20 bridges in Montana during the 2022 calendar year. The purpose of the data collection is to determine if scour and channel instability occur in the vicinity of the bridge structures. Data were processed...
Water-Quality Data in and near Groundwater Flow-Through Kettle-Hole Lakes, Western Cape Cod, Massachusetts, 2003 - 2018 Water-Quality Data in and near Groundwater Flow-Through Kettle-Hole Lakes, Western Cape Cod, Massachusetts, 2003 - 2018
This U.S. Geological Survey (USGS) data release provides a comprehensive dataset of water-quality results, physical-parameter measurements, hydrologic measurements, and site information collected to study the nature and extent of water quality along groundwater flow paths adjacent to glacial-kettle lakes on Cape Cod, Massachusetts. Water-quality samples were collected in 2003, 2005, and...
Biological N-cycling data from soils collected along an elevation gradient in the CO Front Range (2018-2019) (ver. 2.0, November 2024) Biological N-cycling data from soils collected along an elevation gradient in the CO Front Range (2018-2019) (ver. 2.0, November 2024)
Atmospheric deposition of reactive nitrogen (Nr) can impact the soil microbial community structure and function and thus ecosystem processing and export of nutrients. Ecosystem response to atmospheric inputs of nitrogen depends on several factors, including elevational climate conditions (freeze/thaw cycles, precipitation), geology, soil and vegetation type, N speciation and microbial...
Seasonal Atmospheric Nitrate and Ammonium Deposition along an Elevation Gradient in the Colorado Front Range using Ion Exchange Resin Columns (2018-2019) Seasonal Atmospheric Nitrate and Ammonium Deposition along an Elevation Gradient in the Colorado Front Range using Ion Exchange Resin Columns (2018-2019)
Atmospheric deposition of reactive nitrogen (Nr) due to human activities can have measurable effects on ecosystem processing and export of nutrients, groundwater and surface-water quality. Rates of Nr deposition to lower-elevation forests immediately adjacent to the Denver/Boulder urban area, however, have only recently been measured. The focus of this study was to determine the extent...
