Electrofishing is currently the most common method used to assess freshwater fish communities. Although conventional electrofishing practices are considered effective there are inherent limitations. One alternative method for evaluating fish assemblage dynamics is the sequencing of environmental DNA (eDNA) extracted from water samples. Although eDNA sampling has become more common in...

We report two draft genomes of previously undescribed Mycobacterium spp. isolated from invasive Northern snakehead (Channa argus) inhabiting the Chesapeake Bay Watershed, USA. The average nucleotide identity between these isolates and other available genomes was

This dataset contains gene expression data for brook trout (Salvelinus fontinalis) collected from the Loyalsock Creek watershed in Pennsylvania. Gene expression was quantified for three genes of interest: elongation factor 1-alpha (EF1), SfontSerpinh1 (a heat shock protein gene), and SfontColdRNA (a gene associated with cold response). The dataset was generated to support investigations...

Per- and polyfluoroalkyl substances (PFAS) are a class of ubiquitous, environmentally persistent compounds that pose a threat to human and wildlife health. Ospreys (Pandion halieatus) are a model avian species with a documented history of serving as effective bioindicators of contamination. Our study aims to provide a more thorough understanding of PFAS presence in the Chesapeake and...

Cambarus chasmodactylus (New River Crayfish) is one of the largest crayfish species occurring in the Appalachian Mountains and occupies a niche similar to several highly imperiled crayfishes within the same region.Little is known about the behavior and relationship between female crayfishes of this species and their young, and this unexpected clustering behavior of neonates about the...

Data from environmental DNA (eDNA) samples filtered from seawater collected in the Gulf of America during a research expedition on the NOAA Ship Pisces from June 30-July 11, 2022. Samples were collected at depths throughout the water column using Niskins mounted to rosettes on Connectivity-Temperature-Depth instruments (CTDs). Each eDNA sample was amplified using four primer sets: MiFish...

Data from environmental DNA (eDNA) samples filtered from seawater collected in the Gulf of America during a research expedition on the R/V Nancy Foster in August 2022. Samples were collected at depths throughout the water column using Niskins mounted to rosettes on Connectivity-Temperature-Depth instruments (CTDs) or Niskins mounted to remote operated vehicles (ROVs). Each eDNA sample...

Data from environmental DNA (eDNA) samples filtered from seawater collected in the Gulf of America during a research expedition on the R/V Point Sur in September 2022. Samples were collected at depths throughout the water column. Each eDNA sample was amplified using four primer sets: MiFish 12S rRNA marker targeting ray-finned fishes; 28S rRNA marker targeting corals and other cnidarians...

This record contains data generated from a laboratory-based study examining the persistence of warm water acclimation following cold water recovery in an iconic cold-water species, the Eastern brook trout. The data set includes Critical Thermal Tolerance (CTmax) measures of fish in treatment groups: control (15 degrees C throughout), 1, 3, 7, and 14 days in warm water exposure (22...

Sediment accretion measurements were made at the SMARTX warming experiment at the Smithsonian Environmental Research Center's Global Change Research Wetland. Feldspar marker horizons were established at the beginning of the experiment in 2016 in the warming plots, and were subsequently buried over time by wetland accretion of both organic and inorganic matter. These data include the...

As stream temperatures increase, cold water adapted brook trout populations are projected to decline. However, there are mechanisms brook trout can use to persist in warming streams. Those mechanisms include acclimation, adaptation, and utilizing cold water refugia in streams where thermal heterogeneity is high. Using implanted temperature recording tags, this study examines individual...

The data were collected to examine the impact of thiamine deficiency and replacement with thiamine on the swimming ability of American eels.
