2004-2010 Chesapeake Bay Smallmouth and Largemouth Bass Estrogenic Biomarker Data
The data was gathered to document the extent and severity of biomarkers of exposure to estrogenic chemicals in smallmouth and largemouth bass. Samples were collected from 2004 through 2010 at sites in five watersheds within the Chesapeake Bay watershed. A total of 281 largemouth bass were collected from the Potomac, Susquehanna, Patuxent and Rappahannock rivers and 1,384 smallmouth bass...
Data release for: Does the quality and quantity of honey bee-collected pollen vary across an agricultural land-use gradient?
This dataset includes pollen sample weight in grams and percent crude protein collected by honey bees (Apis mellifera) across 38 apiaries in Minnesota, North Dakota, and South Dakota approximately weekly from June through September in 2015 and 2016. Additionally it includes the hectares of different land covers (corn, Zea mays, & soybeans, Glycine max, grasslands, bee forage crops, and...
Plague causes fragmentation of prairie dog colonies in Conata Basin, South Dakota from 1993 - 2015
This data was used to investigate the invasion of a non-native disease, plague, to a keystone species, prairie dogs, in Conata Basin, South Dakota, United States. We documented the resulting extent of fragmentation and habitat loss in western grasslands using colony boundaries mapped by the USFS every one to three years from 1993 - 2015. Specifically, we assessed how the arrival of...
Non-listed disease report to OIE (World Organisation for Animal Health) for the 1st semester of 2019
As a member of the World Organisation for Animal Health (OIE), and the reporting authority for the United States, the USGS National Wildlife Health Center (NWHC) is responsible for reporting wildlife disease outbreaks that involve diseases which are not OIE-listed (https://www.oie.int/wahis_2/public/wahidwild.php# ). These outbreaks are to be reported on a semesterly basis via OIE's...
Diagnostic and field data from the Eastern Migratory Whooping Crane Population
Detailed data collected from the field and generated during diagnostic evaluation of whooping crane carcasses from the Eastern Migratory Population.
Maternal transfer of PCBs in Pacific sand lance in Puget Sound, Washington
Data included in this release are from Pacific sand lance and water, sediment and suspended particulate matter collected at two sites in Puget Sound, Washington, which were evaluated for PCB concentration. PCB congener data are stored in the U.S. Fish and Wildlife Service's Environmental Contaminant Data Management System (ECDMS), accessible through the Wildlife & Environmental...
Growth of cultured Picocystis strain ML in the presence of arsenic, and occurrence of arsenolipids in these Picocystis as well as biota and sediment from Mono Lake, California
Mono Lake is a hypersaline soda lake rich in dissolved inorganic arsenic with its primary production currently dominated by Picocystis str. ML. We set out to determine if this picoplankter could metabolize inorganic arsenic, and in doing so form unusual arsenolipids (e.g., methylated arsinoyl ribosides) as reported in other saline ecosystems and by halophilic algae. We cultivated...
Survival and growth of juvenile freshwater mussels in a flow-through auto-feeding system
Survival and growth of four species of juvenile mussels in a pulsed flow-through auto-feeding beaker system.
Consumption rates and total mercury concentration of food items and consumers collected at six sites on the Colorado River in the Grand Canyon, USA, 2007-2009
Consumption rates and total mercury concentration of food items and consumers collected at six sites on the Colorado River in the Grand Canyon. Sites ranged from 0-367 river kilometers downstream of Lees Ferry (AZ, USA). Samples were analyzed for total Hg using cold vapor atomic fluorescence (CVAF, Tekran Model 2600 CVAF spectrometer) following EPA Method 7474. Consumption rate samples...
Data for the assessment of the containment pond at Canyon Mine, Arizona, 2019
These data are comprised of measurements of elements (e.g., uranium, cobalt, nickel, copper, zinc, cadmium, lead, etc.), major anions (chloride, nitrite+nitrate as nitrogen, sulfate, etc.), dissolved organic carbon, and general water quality characteristics in Canyon Mine containment pond water, sediment, vegetaiton and invertebrate samples collected in calendar year 2019.
Chemical and biological data from acute and chronic exposure to sodium nitrate and sodium sulfate for several freshwater organisms in water-only bioassays
The responses (survival, growth, and/or reproduction) of test organisms in six concentrations of toxicants in several test waters with different water quality characteristics. In addition to the individual biological data, chemical, and water quality measurements from each toxicity test are also reported. Test organisms include unionid mussels (Lampsilis siliquoidea, Villosa iris), a...
