Biomass accrual and trace-element concentrations in water and periphytic algae at select locations in the Clark Fork and Blackfoot Rivers, Montana, 2015 Biomass accrual and trace-element concentrations in water and periphytic algae at select locations in the Clark Fork and Blackfoot Rivers, Montana, 2015

The U.S. Geological Survey monitored algal biomass accrual and concentrations of metals and other trace elements in stream water and periphytic algae at 3-4 day intervals over a 2-week period at 3 locations within the upper and middle portions of the mining-impacted Clark Fork River, Montana, and at one location on the relatively unimpacted Blackfoot River tributary. This data release...

Sequence Information from the Mitogenome and Four Nuclear Genes from Holarctic Ermine (Mustela spp.) Sequence Information from the Mitogenome and Four Nuclear Genes from Holarctic Ermine (Mustela spp.)

These data are comprised of two tables, one of primers used for PCR amplifications and the other containing North American (n = 105), Mongolian (n = 1) and Russian (n = 5) ermine (Mustela spp.) sample accessions and NCBI GenBank DNA sequence accessions for mitogenomes and four nuclear genes (agouti signaling protein [ASIP], feline sarcoma [FES], growth hormone receptor [GHR], and...

Liquid Chromatography Triple Quadrupole Mass Spectrometry (LC/MS/MS) analysis of cyanobacteria cultures from Lake Elsinore and Canyon Lake (CA, USA, 2016) for cyanotoxins and algal toxins Liquid Chromatography Triple Quadrupole Mass Spectrometry (LC/MS/MS) analysis of cyanobacteria cultures from Lake Elsinore and Canyon Lake (CA, USA, 2016) for cyanotoxins and algal toxins

Cyanobacteria are common in inland water bodies. Many strains are known to produce potent toxins (cyanotoxins) which can impact human and animal health in sufficient concentrations. Lake Elsinore and Canyon Lake are two impaired lakes in California with frequent cyanobacteria blooms that are not monitored for toxin production. These data document the liquid chromatography triple...

Microbial Source Tracking Marker Concentrations in Congaree National Park in 2017-2019, South Carolina, USA Microbial Source Tracking Marker Concentrations in Congaree National Park in 2017-2019, South Carolina, USA

The dataset contains quantitative polymerase chain reaction data for microbial source tracking markers screened on water samples collected from streams and rivers within and bounding Congaree National Park from samples collected throughout the year from December 2017 through June 2019. The number of samples collected per event ranged from 4-16 over the span of 11 sample events.

Target-Chemical Concentration Results of Mixed-Organic/Inorganic Chemical Exposures in Cape Cod, Massachusetts Tapwater, 2018 Target-Chemical Concentration Results of Mixed-Organic/Inorganic Chemical Exposures in Cape Cod, Massachusetts Tapwater, 2018

This dataset provides the water-quality results for organic and inorganic concentrations analyzed from samples collected at residential tapwater faucets, sourced from private drinking water wells in Cape Cod, Massachusetts. Samples were collected in July and August, 2018 from 20 locations. Samples were analyzed at various U.S. Geological Survey laboratories: the National Water Quality...

Liquid Chromatography Triple Quadrupole Mass Spectrometry (LC/MS/MS) analysis of cyanotoxins and algal toxins in estuary samples collected from California, USA, in 2016-17 Liquid Chromatography Triple Quadrupole Mass Spectrometry (LC/MS/MS) analysis of cyanotoxins and algal toxins in estuary samples collected from California, USA, in 2016-17

Cyanobacteria are primary producers present in many water bodies, certain types of which may produce potent toxins (known as cyanotoxins). They are known to impact human and animal health when exposed through recreational activities, consumption, and inhalation. In an effort to understand the presence of toxin-producing cyanobacteria in California water bodies, cyanobacteria samples were...

Carbon and Nitrogen Isotope Concentrations in Polar Bear Hair and Prey from the Alaska Beaufort and Chukchi Seas, 1978-2019 Carbon and Nitrogen Isotope Concentrations in Polar Bear Hair and Prey from the Alaska Beaufort and Chukchi Seas, 1978-2019

This dataset includes carbon and nitrogen isotope concentrations measured in polar bear hair and marine mammal prey samples collected 1978-2017 in the Beaufort and Chukchi Seas. Marine mammal prey samples were collected opportunistically either from polar bear seal kill sites or from marine mammals harvested by Native hunters. Hair was collected from polar bears captured on the sea ice...

Fatty Acid Composition of Polar Bear Adipose Tissue and Ringed and Bearded Seal Blubber Collected in the Chukchi Sea, 2008-2017 Fatty Acid Composition of Polar Bear Adipose Tissue and Ringed and Bearded Seal Blubber Collected in the Chukchi Sea, 2008-2017

These data are the fatty acid compositions (in percent) of adipose tissue samples collected from polar bears and of blubber samples collected from ringed and bearded seal killed by polar bears in the Chukchi Sea, 2008-2017. The dataset includes sex, age, and age class of the bears that were sampled. The data are provided as percent of each fatty acid identified via nomenclature that...

Immunological histopathology of American kestrels (Falco sparverius) exposed to the flame retardant isopropyl triphenyl phosphate Immunological histopathology of American kestrels (Falco sparverius) exposed to the flame retardant isopropyl triphenyl phosphate

This work is part of a study of the immunological effects of exposure to alternative flame retardants in avian species. For the pathology portion of the study, hatchling American kestrels (Falco sparverius) were exposed to the flame retardant isopropyl triphenyl phosphate (ITP) and then challenged with a synthetic analogue of viral double-stranded RNA, polyinosinic:polycytidylic acid...

Immunological histopathology of American kestrels (Falco sparverius) exposed in ovo to two persistent organic pollutants -- SCCPs and TBBPA-BDBPE Immunological histopathology of American kestrels (Falco sparverius) exposed in ovo to two persistent organic pollutants -- SCCPs and TBBPA-BDBPE

This work is part of a study of the immunological effects of exposure to alternative flame retardants in avian species. For the pathology portion of the study, spleens and bursas from American kestrels (Falco sparverius) exposed by egg injection to varying doses of short-chain chlorinated paraffins (SCCPs) and the flame retardant TBBPA-BDBPE were examined microscopically for...

Necropsy reference number and summary collection information for Washington state population of northern sea otters examined during 1989-2010 Necropsy reference number and summary collection information for Washington state population of northern sea otters examined during 1989-2010

Morbillivirus epidemics in marine mammals first gained prominence in 1988 when an outbreak of phocine distemper virus (PDV) occurred in European harbor seals (Phoca vitulina vitulina). Prior to 2001, all serosurveys for morbilliviruses in sea otters (Enhydra lutris) in California, Washington and Alaska documented a 0% seroprevalence. The first published serodetections of morbillivirus in...

Chemical and biological data from acute toxicity tests with road dust suppressant chemicals and five freshwater organisms Chemical and biological data from acute toxicity tests with road dust suppressant chemicals and five freshwater organisms

Dust suppressants and soil stabilizer products are applied to unpaved roads worldwide to reduce dust production and stabilize road surfaces. Although these products may enter roadside surface water through runoff or leaching, little information is available on environmental fate or aquatic toxicity. The data reported here include the acute toxicity of 27 dust suppressant/soil stabilizer...
