Data

This dataset includes biological variables showing surf smelt spawning presence, geological variables describing beach composition, and sample locations using RTK-GPS. This field data was also used to run the Sea Level Affecting Marshes Model (SLAMM; Warren Pinnacle Consulting, Inc., Warren, Vt)) to predict the changes to beaches over time, and under different sea level rise scenarios. Field sampl

A quantitative PCR (qPCR) assay was developed to detect nuclear inclusion X (NIX) in Pacific razor clams, and assay specificity was confirmed by chromogenic in situ hybridization (CISH). Both tests were applied to evaluate NIX infections in wild Pacific razor clams collected during spring 2019. Consistent with results from earlier histopathological assessments, qPCR and CISH indicated 100% prevale

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 Contaminants Mapper

Piscine orthoreovirus genotype one (PRV-1) is the causative agent of heart and skeletal muscle inflammation (HSMI) in farmed Atlantic salmon (Salmo salar L.). The virus has also been found in Pacific salmonids in western North America, raising concerns about the risk to native salmon and trout. Here, we report the results of laboratory challenges using juvenile Chinook salmon, coho salmon, and rai

We conducted a study to test the factors related to detectability of two invasive aquatic plants (Egeria densa and Myriophyllym spicatum) using environmental DNA (eDNA), over extended periods of time, and specifically examined how plant growth stage and abundance relates to eDNA detection in semi-natural and natural conditions. This dataset is from sampling performed in summer of 2018 in lakes wit

This database is the result of an extensive literature search aimed at identifying documents relevant to the emerging field of dam removal science. In total the database contains 214 citations that contain empirical monitoring information associated with 181 different dam removals across the United States and abroad. Data includes publications through 2016 and supplemented with the U.S. Army Corps

Columns of data representing Chehalis River tributary, sample reach locations, dates of water sampling, quantitative PCR results, and whether lamprey were sampled by electrofishing in each sample reach. ***Please note that the title of this data release used to be "Environmental DNA surveys for lampreys in Chehalis River tributaries, Washington, from 2015 and 2017," but was updated for version 2.

Bacterial kidney disease (BKD) caused by Renibacterium salmoninarum (Rs) occurs nearly worldwide where wild or cultured salmonid fishes are present. Control of BKD is confounded by its two modes of transmission, horizontal (fish-to-fish) and vertical (from female parent to progeny via the eggs). A highly successful BKD control strategy employed in Pacific Northwest hatcheries culturing spring Chin

Data are abundance and body size (length) of juvenile salmon, forage fish, and other species captured with a lampara net in eelgrass and nearby unvegetated habitat on the Skagit River Delta monthly, April-September, 2008-2010, as well as vegetation status, water depth, temperature, salinity, and clarity for each fish netting event.

Physical and chemical changes affect the biota within urban streams at varying scales ranging from individual organisms to populations and communities creating complex interactions that present challenges for characterizing and monitoring the impact on species utilizing these freshwater habitats. Salmonids, specifically cutthroat trout (Oncorhynchus clarkii) and coho salmon (Oncorhynchus kisutch),

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), dissolved

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.
