This dataset describes environmental DNA (eDNA) sample collections, DNA extractions, and DNA copy numbers (abundance of environmental DNA) for cisco Coregonus artedi, a native prey fish of restoration interest in the Laurentian Great Lakes, in tributaries to Lake Huron’s North Channel in Canada. Samples were collected during cisco spawning runs (mid-November) from 2022-2024.

This data set includes metadata for fish and microbes from water samples collected in southern Lake Michigan in August 2021. All field eDNA samples were collected using a Tethys-class Long Range Autonomous Underwater Vehicle (LRAUV) carrying an eDNA sampler, the 3G Environmental Sample Processor (ESP). Water samples were collected at various depths within following target layers: the...

We used visual encounter surveys (VES) and environmental DNA (eDNA) surveys for amphibians in the western united states. Data are results of both VES and eDNA surveys for all amphibian species that occur in the locations surveyed.

Craig County, Virginia hosts large (>500 m wide) blockslides and rock slumps along the southeastern slopes of several mountains. These features differ from Virginian boulder fields in several aspects, most significantly in soil development, foliage, and clast size. In contrast with freshly exposed, likely periglacial, boulder fields that commonly contain centimeter to meter-sized...

Glacial and proglacial landscapes provide critical sources of water and solutes to downstream riverine and marine ecosystems. This dataset contains samples from the dominant landscape types in the Nellie Juan River basin, collected from surface streams, groundwater, rain, and snow. Water samples were also collected from streams near the Exit, Gulkana, and Kennicott Glaciers. Snow samples...

Two digital video cameras (CACO-01 c1 and c2) were installed at Head of the Meadow Beach, Cape Cod National Seashore in Massachusetts (MA) as part of a U.S. Geological Survey (USGS) research project to study the beach and nearshore environment. The cameras were located near the top of the 18 meter high bluff and faced north-east (c1) and east (c2) along the beach. They ran from December...

Pollutants present in stormwater runoff can severely degrade water quality in aquatic habitats. The tire-derived chemical 6PPD-quinone is one such pollutant present in stormwater that is known to significantly impact the survival of salmonids. 6PPD-quinone is derived from 6PPD, the primary antiozonant used to protect tire rubber from ozone attack and degradation. Alternative antiozonants...

Aspen stands (Populus tremuloides Michx.) are declining in western U.S. forests due to drought, changing climate, and altered disturbance regimes. Management of aspen has focused on promoting vegetative suckering, which requires viable rootstock. With increasing wildfire frequency and severity in the West, there are opportunities for aspen reforestation post-fire. We tested how deadwood...

The dataset supports studies performed in Washington state in 2022 and 2023 that investigated how detection of European green crab eDNA is affected by sampling season, green crab density, and the time at which samples are collected across a tide cycle. The data include sample site locations and descriptive categories, volume of water (L) filtered for eDNA analysis for each sampling event...

In this study, we demonstrate that infectious hematopoietic necrosis virus (IHNV), which made a host jump from sockeye salmon (Oncorhynchus nerka) to rainbow trout (O. mykiss), has not conformed to classical pathogen evolution theory. We quantified virulence in the endemic and novel hosts using common garden in vivo experiments with 16 archival IHNV isolates collected from 1972-2017...

This data release contains the boundaries of assessment units, assessment input data, and resulting fact sheet data tables for the assessment of undiscovered conventional oil and gas resources of the Greater Carpathian Area. The assessment unit is the fundamental unit used in the National and Global Oil and Gas Assessment NAGA Project for the assessment of undiscovered oil and gas...
