Temporal patterns in glyphosate and atrazine concentrations were measured weekly by the U.S. Geological Survey (USGS) during the 2013 growing season in 100 small streams in the Midwestern United States. Concentrations also were measured every 2 days at a subset of 8 of the sites, all located in Missouri. Glyphosate was detected more frequently in urban streams than in agricultural streams, and at concentrations similar to those in streams with high agricultural land use in the watershed. In contrast, atrazine was detected more frequently and at higher concentrations in agricultural streams than in urban streams. This data release provides watershed characteristics and 2013 glyphosate and atrazine compound concentrations...

It is unclear whether DNA lysis buffers used for preservation of whole blood samples from Hawaiian forest birds cause denaturation and loss of antigen binding capability of antibody molecules. If their antigen binding capability is not affected, then the samples can be used in serological assays to provide an independent assessment of the accuracy of PCR (polymerase chain reaction) diagnostic tests for avian malaria. This data set reports raw absorbance measurements that were collected with a BioRad Model 3550 ELISA plate reader at a wavelength setting of 405 nm for different dilutions of blood from an infected Hawaii Amakihi that were preserved in PBS (phosphate buffered saline), TEN (Tris-Ethylenediaminetetraacetic...

This data release contains cyanotoxin concentrations for microcystins, cylindrospermopsins, anatoxins, and saxitoxins assessed using Enzyme-Linked Immunosorbent Assays (ELISA) on 363 samples collected from 82 surface-water sites located in the Cascade Range in Oregon, and eight sites located outside of the Oregon Cascade Range in Washington and California, during 2016-2020. Three sample types were assessed: 1) benthic colonies and mats of cyanobacteria (n=109), 2) plankton net tows (n=90), and 3) Solid Phase Adsorption Toxin Tracking samplers (SPATTs)(n=164).

It is unclear whether DNA lysis buffers used for preservation of whole blood samples from Hawaiian forest birds cause denaturation and loss of antigen binding capability of antibody molecules. If their antigen binding capability is not affected, then the samples can be used in serological assays to provide an independent assessment of the accuracy of PCR (polymerase chain reaction) diagnostic tests for avian malaria. This data set provides derived Percent ELISA (Enzyme linked Immunosorbant Assay) Values calculated from adjusted absorbance measurements that were collected with a BioRad Model 3550 ELISA plate reader at a wavelength setting of 405 nm.

This data set provides raw absorbance measurements that were collected with a BioRad Model 3550 ELISA plate reader at a wavelength setting of 405 nm for different dilutions of blood from an uninfected Hawaii Amakihi. The blood was preserved in different lysis buffers or placed in phosphate buffered...

It is unclear whether DNA (Deoxyribonucleic Acid) lysis buffers used for preservation of whole blood samples from Hawaiian forest birds cause denaturation and loss of antigen binding capability of antibody molecules. If their antigen binding capability is not affected, then the samples can be used in serological assays to provide an independent assessment of the accuracy of PCR (polymerase chain reaction) diagnostic tests for avian malaria. This data release consists of three tabular datasets of raw absorbance measurements that were collected with a BioRad Model 3550 ELISA (Enzyme linked Immunosorbant Assay) plate reader at a wavelength setting of 405 nm from serial dilutions of whole blood that were preserved with...

From 2017-2019, the Upper Midwest Environmental Sciences Center (UMESC) analyzed microcystin concentrations in samples collected from three different studies. The first study was on the movement and distribution of invasive carp (Bighead Carp, Silver Carp, Grass Carp) in the upper Mississippi River between lock and dam 16 and lock and dam 19. Samples were collected from May through October of 2017 and 2018 from backwaters, impounded areas and main channel areas in this reach of the Mississippi River. The second study was a nutrient and metal amendment study performed on natural phytoplankton communities from Lake Erie and Lake Michigan. This was a laboratory study where natural phytoplankton communities were incubated...
