Low-Flow Period Seasonality, Trends, and Climate Linkages Across the United States Data Release Low-Flow Period Seasonality, Trends, and Climate Linkages Across the United States Data Release
This metadata record describes data that characterize low-flow period duration and seasonality, as well as trends and climate linkages at streamgages across the conterminous United States. These data are associated with a publication which looks to answer three questions about low-flow periods in the conterminous United States: (1) how long are these periods and when do they typically...
Age estimates of captured Black Carp (Mylopharyngodon piceus) using four calcified structures, 2017-2019 Age estimates of captured Black Carp (Mylopharyngodon piceus) using four calcified structures, 2017-2019
A total of 236 Black Carp were collected throughout the year from 2017-2019 by incidental captures of commercial fishers and biologists. Capture date, river basin of capture location, and coordinates were recorded for each Black Carp captured. A subsample of 119 Black Carp varying from 429-1268 millimeters total length were compared for the precision of annuli counts by two experienced...
Detrital Zircon U-Pb and Hf isotope data from selected Appalachian rivers Detrital Zircon U-Pb and Hf isotope data from selected Appalachian rivers
This data release contains zircon U-Pb (n=1467) and Hf (n=332) data for five modern rivers (Connecticut, Susquehanna, Roanoke, Peedee, and Chattahoochee) draining the Appalachian mountain belt. The data show that zircon crystallization ages are characterized by several discrete populations that often correspond with orogenic episodes in the Mesoproterozoic and Paleozoic, with distinct...
Size, attachment material and efficacy of piscicide delivery vials and baits for control of black carp, Mylopharyngodon piceus Size, attachment material and efficacy of piscicide delivery vials and baits for control of black carp, Mylopharyngodon piceus
A piscicide delivery method was designed to selectively target black carp Mylopharyngodon piceus, an invasive species in North America which possesses specially adapted pharyngeal teeth for crushing mollusk prey. Bait was prepared by attaching a glass vial containing toxicant (antimycin A) to the exterior of Corbicula fluminea clam valve. The vial was designed to break by the force...
Development and testing of a qPCR assay for Lampsilis siliquoidea eDNA Development and testing of a qPCR assay for Lampsilis siliquoidea eDNA
Data describe specificity and sensitivity testing for the L.sil2 assay. This assay is used to amplify eDNA from the freshwater mussel Lampsilis siliquoidea.
Development, testing and use of four species-specific qPCR assays for freshwater mussel eDNA detection in the Niobrara River Development, testing and use of four species-specific qPCR assays for freshwater mussel eDNA detection in the Niobrara River
This data consists of information on the specificity and sensitivity of 4 species specific qPCR assays for the detection of eDNA from 4 species of freshwater mussels, specifically Lampsilis cardium, Lampsilis siliquoidea, Pyganodon grandis, and Anodontoides ferussacianus. The data also contain the results of eDNA sampling in Niobrara River at Niobrara National Scenic River and Agate...
