Data on the behavior of grass carp, silver carp, and bighead carp during laboratory exposures to the amino acids L-alanine, L-arginine, L-aspartic acid, and L-glutamic acid Data on the behavior of grass carp, silver carp, and bighead carp during laboratory exposures to the amino acids L-alanine, L-arginine, L-aspartic acid, and L-glutamic acid
These data pertain to behavior trials conducted on three different species of invasive carp in a laboratory setting between the dates of 29 April 2021 to 14 December 2021. The three species tested were grass carp (Ctenopharyngodon Idella), bighead carp (Hypophthalmichthys nobilis) and silver carp (H. molitrix). The amino acids L-alanine, L-arginine, L-aspartic acid, and L‑glutamic acid...
U-Pb zircon geochronology and whole rock geochemistry data for Auminzatau and Kuldjuktau mountains, Kyzylkum desert, Uzbekistan U-Pb zircon geochronology and whole rock geochemistry data for Auminzatau and Kuldjuktau mountains, Kyzylkum desert, Uzbekistan
These U-Pb zircon geochronology and whole rock geochemistry data were collected as part of a bilateral campaign of the U.S. Geological Survey (USGS) with the Uzbekistan Ministry of Mining, Industry, and Geology (MinGeology; formerly GOSCOMGeology) to support a new quantitative/qualitative mineral resource assessment for tungsten, gold, rare-earth elements, graphite, and uranium in the...
Biological soil crust metagenomic data from Horse Heaven Hills, Washington, measured in 2020 Biological soil crust metagenomic data from Horse Heaven Hills, Washington, measured in 2020
This dataset contains Sanger ITS sequences from biocrust lichen taxa collected at Horse Heaven Hills in Washington, USA. It also includes metagenomic biocrust lichen data from 20 plots at Horse Heaven Hills in Washington, USA. These data were collected by Bruce McCune and Heather Root in 2019-2020 and sequenced for ITS using bulk sequencing in the PacBio system at Brigham Young...
Data describing a predatory fish invasion on a riverine food web Data describing a predatory fish invasion on a riverine food web
Catfishes are opportunistic feeders that are among the world's worst invasive species. Flathead catfish *Pylodictus olivaris* -- a large predatory catfish -- were first detected in the Susquehanna River, Pennsylvania, USA in 2002. Since then, they established a viable and rapidly growing population that is expanding its range throughout the river system. Although the predatory effects of...
Grade and tonnage data for lithium, cesium, and rubidium pegmatite deposits Grade and tonnage data for lithium, cesium, and rubidium pegmatite deposits
Pegmatites are a major host of global lithium, cesium, and rubidium resources. However, the existing grade and tonnage dataset for lithium pegmatites that was published in 1992 does not represent the current industry parameters used to delineate resources. There are no existing grade and tonnage datasets for cesium and rubidium. We present grade and tonnage data for lithium, cesium, and...
Bathymetry, topography, and sediment grain-size data from the Elwha River delta, Washington, August 2019 Bathymetry, topography, and sediment grain-size data from the Elwha River delta, Washington, August 2019
Two dams on the Elwha River, Washington State, USA trapped over 20 million m3 of sediment, reducing downstream sediment fluxes and contributing to erosion of the river's coastal delta. The removal of the Elwha and Glines Canyon dams between 2011 and 2014 induced massive increases in river sediment supply and provided an unprecedented opportunity to examine the response of a delta system...
