Baseline fish health information on pallid sturgeon and bull trout or appropriate surrogate species (shovelnose sturgeon, cutthroat trout, mountain whitefish) in critical habitats with elevated risks of oil spills. Shovelnose sturgeon (Scaphirhynchus platorynchus) were collected in three locations near the confluence of the Missouri and Yellowstone Rivers and cutthroat trout (Oncorhynchus clarki lewisi) and mountain whitefish (Prosopium williamsoni) were collected from critical bull trout habitat along the Middle Fork of the Flathead River. Fish health metrics evaluated included gene expression/enzyme induction in various tissues, differential changes in white blood cells, polycyclic aromatic hydrocarbon bile metabolites,...
In crude-oil-contaminant plumes the dissolved organic carbon (DOC) is mainly hydrocarbon degradation intermediates only partly quantified by the diesel range total petroleum hydrocarbon (TPHd) method. To understand potential biological effects of degradation intermediates we tested three fractions of DOC: (1) solid phase extract (HLB); (2) dichloromethane (DCM-total) extract used in TPHd; and (3) DCM extract with hydrocarbons isolated by silica gel cleanup (DCM-SGC). Bioactivity of extracts from five wells spanning a range of DOC was tested using an in vitro multiplex reporter system that evaluates modulation of activity of 46 transcription factors; extracts were evaluated at concentrations equivalent to the well...
This dataset represents a modeling effort intended to explore the impacts of oiling on migratory birds. The purpose of this model is to provide a first principles approach to predict potential biological impacts of altered energetics dynamics in north American migratory birds due to oiling of feathers. This data includes predicted theoretical impacts on migration timing, wintering latitude, starvation rates, and increased food uptake. This data was generated through model implementation in R (R Core Team 2020; Version 4.0.4).
This data describes the relative luminescence units (RLUs) and relative fluorescence units (RFUs) of lysates of aryl-hydrocarbon responsive chemically-activated luciferase expression human hepatoma HG2L7.5c1 cells which were exposed for 4 or 24 h to beta-naphthoflavone dilutions, 2,3,7,8-tetrachlorodibenzo-p-dioxin dilutions, or dilutions of groundwater extracts collected from wells within or near an oil-contaminated area. This data also describes RFUs of bovine serum albumin standards which were used to convert the RFUs of the cell lysates to protein with which to normalize the RLUs of the cell lysates.
