Concentrations of environmental DNA (eDNA) during sockeye salmon spawning in 2016, Hansen Creek, Alaska, USA Concentrations of environmental DNA (eDNA) during sockeye salmon spawning in 2016, Hansen Creek, Alaska, USA
This dataset contains environmental DNA (eDNA) concentrations and spawning adult abundances for sockeye salmon (Oncorhynchus nerka) in Hansen Creek, a small tributary in the Wood River watershed, southeast Alaska, USA. We took temporally- and spatially-replicated eDNA samples during the spawning period (mid-July through August), along with fish counts (live, naturally dead, and killed)...
Dataset: Mortality trends in the Washington population of northern sea otters (Enhydra lutris kenyoni) during 20022015 Dataset: Mortality trends in the Washington population of northern sea otters (Enhydra lutris kenyoni) during 20022015
These data document cause of death determination for stranded otters salvaged from the coast of Washington state and northern Oregon for post-mortem analysis.
Distribution and seasonal differences in Pacific Lamprey and Lampetra spp eDNA across 18 Puget Sound watersheds, 2014 and 2015 Distribution and seasonal differences in Pacific Lamprey and Lampetra spp eDNA across 18 Puget Sound watersheds, 2014 and 2015
These data contain all the raw results needed to support the conclusions for the final product. These data are water sampling locations (latitude and longitude), date of water sampling, quantitative PCR values for each water sample, and stream flow at USGS stream gauging stations on sampling day.
SPV field trials bait uptake data SPV field trials bait uptake data
These data were collected as part of a field trial to test the effectiveness of a sylvatic plague vaccine (see Rocke et al., 2017 for details). Vaccine and control plots were selected randomly from the available pairs at each location. Baits containing Rhodamine B, a biomarker, were distributed at each plot. At least 1 week and no more than 2 months post-baiting each year, local...
Data collected in 2008-2014 to assess nearshore subtidal community response to increased sediment load during removal of the Elwha River dams, Washington State, USA Data collected in 2008-2014 to assess nearshore subtidal community response to increased sediment load during removal of the Elwha River dams, Washington State, USA
Data are time series of substrate grain size, remotely sensed water column turbidity, and measures of abundance (e.g., density, percent cover) of the nearshore subtidal (3-17 m depth) benthic community (vegetation, invertebrates, and fish) collected before (2008-2011) and during dam removal (2012-2014).
Emerging fungal pathogen Ophidiomyces ophiodiicola in wild European snakes Emerging fungal pathogen Ophidiomyces ophiodiicola in wild European snakes
Snake fungal disease (SFD) is an emerging disease of wild snakes in eastern North America caused by the fungus Ophidiomyces ophiodiicola. Recently, the disease has also been detected in wild snake in Europe. The data presented here describe: 1) culture, PCR, and histopathology results of wild European snakes opportunistically sampled for O. ophiodiicola, 2) colony expansion rates of...
Environmental conditions synchronize waterbird mortality events in the Great Lakes: Data Environmental conditions synchronize waterbird mortality events in the Great Lakes: Data
During 2010 to 2013, waterbird mortality surveillance programs used a shared protocol for shoreline walking surveys performed June to November at three areas in northern Lake Michigan. Timing (to day) and location (to transect) of carcass deposition and species affected were summarized. Using these observations, the broader goal of our study was to quantify the spatial synchrony of avian...
Determinants of Pseudogymnoascus destructans within bat hibernacula: data Determinants of Pseudogymnoascus destructans within bat hibernacula: data
This dataset includes data used to summarize trends and identify best-fit models to explain patterns in presence-absence and abundance of Pseudogymnoascus destructans (Pd) in environmental substrates and on bats within six bat hibernacula at different stages of white-nose syndrome (WNS). Data relating to environmental substrates include: dates and relative spatial locations of samples...
Geospatial data for object-based high-resolution classification of conifers within the geographic range of the Bi-State Distinct Population Segment of greater sage-grouse in California and Nevada Geospatial data for object-based high-resolution classification of conifers within the geographic range of the Bi-State Distinct Population Segment of greater sage-grouse in California and Nevada
These products were developed to provide scientific and correspondingly spatially explicit information regarding the distribution and abundance of conifers (namely, singleleaf pinyon (Pinus monophylla), Utah juniper (Juniperus osteosperma), and western juniper (Juniperus occidentalis)) in Nevada and portions of northeastern California. Encroachment of these trees into sagebrush...
Investigation of pharmaceuticals in water, fish, and ospreys nesting in Delaware River and Bay Investigation of pharmaceuticals in water, fish, and ospreys nesting in Delaware River and Bay
Exposure of wildlife to Active Pharmaceutical Ingredients (APIs) is likely to occur but evidence of hazard and risk is limited. One exposure pathway that has received attention is trophic transfer of APIs in a water-fish-osprey food chain. Samples of water, fish plasma and osprey plasma were collected from Delaware River and Bay, and analyzed for 21 APIs. Only 2 of 21 analytes exceeded...
Herbicide safeners and associated stream flow for water samples collected across Iowa and Illinois (2016-2017). Herbicide safeners and associated stream flow for water samples collected across Iowa and Illinois (2016-2017).
Four dichloroacetamide herbicide safeners (AD-67, benoxacor, dichlormid, and furilazole) and two co-applied herbicides (acetochlor and metolachlor) were measured in water samples from 7 streams across Iowa and Illinois. Iowa water samples were collected from March 2016 to June 2017, and Illinois water samples were collected from September 2016 to June 2017. The compounds studied are...
Pathogenic lineage of Perkinsea causes mass mortality of frogs across the USA: Data Pathogenic lineage of Perkinsea causes mass mortality of frogs across the USA: Data
Severe perkinsea data was based on the observation of characteristic gross and microscopic lesions and the morphological identification of Perkinsea organisms within the lesions. Necropsies and gross evaluation of carcasses were carried out under a dissecting microscope. Specimen were collected and submitted to the NWHC as part of mortality investigations and collection of specimen from...
