Data on flea control using fipronil grain bait with black-tailed prairie dogs at Badlands National Park, South Dakota, 2020-2021 Data on flea control using fipronil grain bait with black-tailed prairie dogs at Badlands National Park, South Dakota, 2020-2021
We collected fleas from colonies of black-tailed prairie dogs in Badlands National Park, South Dakota, 2020-2021. Specifically, we tested fipronil grain for flea control on two colonies: Colony A in 2020 and Colony B in 2021. To assess on-host flea numbers (in 2020 and 2021), we anesthetized trapped prairie dogs (and their fleas) with isoflurane in induction chambers for processing. We...
Simulated impacts of feather oiling on avian energetics and migration: R environment model code and raw output Simulated impacts of feather oiling on avian energetics and migration: R environment model code and raw output
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...
Dissolved organic carbon, total petroleum hydrocarbons and and toxicity assay results for Bemidji, MN (2018) Dissolved organic carbon, total petroleum hydrocarbons and and toxicity assay results for Bemidji, MN (2018)
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...
Short vs intermediate-term fate of glucose and oxalic acid in surface and subsurface soils of a coastal grassland near Santa Cruz California Short vs intermediate-term fate of glucose and oxalic acid in surface and subsurface soils of a coastal grassland near Santa Cruz California
Though the primary sources of organic matter to soil are plant inputs, the role of microorganisms as mediators of soil organic carbon preservation is increasingly recognized in the context of biological contributions to long-lived soil organic matter. However, current knowledge of sub-soil processes is insufficient to model microbial-derived carbon flow particularly at depth. Using a...
Toxicity Data for Groundwater Contaminated by Petroleum Hydrocarbons near Bemidji, MN (2016) Toxicity Data for Groundwater Contaminated by Petroleum Hydrocarbons near Bemidji, MN (2016)
Management of petroleum-impacted waters by monitored natural attenuation (MNA) requires an understanding of the toxicology of both the original compounds released as well as the transformation products formed during natural breakdown. Here, we report data from a groundwater plume consisting of a mixture of crude oil compounds and transformation products resulting from a crude-oil release...
Nonvolatile dissolved organic carbon and diesel range organics concentrations measured in 2016 at the Bemidji crude oil study site Nonvolatile dissolved organic carbon and diesel range organics concentrations measured in 2016 at the Bemidji crude oil study site
The Bemidji crude oil spill site is a long-term USGS study site to understand the fate of crude oil in the shallow subsurface. A description of the site can be found at https://mn.water.usgs.gov/projects/bemidji. In 2014 concentrations of non-volatile dissolved organic carbon (NVDOC) were three times higher than diesel range organics (DRO) in the contaminant plume*. This is important...
