Evaluation of DNA yield from various sources for use in single nucleotide polymorphism panels

Genetics studies are used by wildlife managers and researchers to gain inference into a population of a species of interest. To gain these insights, micro-satellites have been the primary method, however, there currently is a shift from micro-satellites to single nucleotide polymorphisms (SNPs). With the DNA requirements being different, an investigation into which samples can provide adequate DNA

Point Location of Myotis septentrionalis Echolocation Passes in Eastern North Carolina and Virginia

These data are the location and date of collection of endangered northern long-eared bat Myotis septentrionalis echolocation passes when the automated bat identification software assessed species presence at a maximum likelihood estimator p-value of less than or equal to 0.05 consistent with the U.S. Fish and Wildlife Service monitoring guideline standards.

Data from the manuscript: Direct evidence for fluid pressure, dilatancy, and compaction affecting slip in isolated faults

Earthquake instability occurs as a result of strength loss during sliding on a fault. It has been known for over 50 years that fault compaction or dilatancy may cause significant weakening or strengthening by dramatically changing the fluid pressure trapped in faults. Despite this fundamental importance, we have no real understanding of the exact conditions that lead to compaction or dilation duri

Data from the manuscript: Electrical properties and anisotropy of schists and fault rocks from New Zealand’s Southern Alps under confining pressure

Electrical resistivity measurements of Alpine Fault, NZ outcrop samples saturated with 0.1 M KCl brine and tested at confining pressure of 5 to 200 MP at room temperature.

Data release for effect of cationic species on the friction of clay-bearing faults

Data are time series of clay shearing tests presented in 'Friction in clay-bearing faults increases with the ionic radius of interlayer cations' by Sakuma et al. in Communications Earth & Environment, 2022. Data were used for Figure 1 and Supplementary Figure 8 in that paper. Files contain shear strength as a function of fault slip in laboratory tests for brine-saturated montmorillonite clay.

Breeding songbird tissue analysis and metal concentrations in tissues, soil and invertebrates collected near nesting sites within the Southeast Missouri Lead Mining District, 2016-19

This dataset provides results for the following: (1) metals concentrations in soils surrounding breeding song bird nest sites; (2) metals concentrations in invertebrates (earthworm and grub composites) collected near nest sites; (3) metals concentrations and delta-aminolevulinic acid dehydratase (ALAD) activity in avian blood samples; and (4) metals concentrations, indicators of oxidative stress a

Data used to test a video monitoring and computational system for estimating juvenile fish abundance

We developed and tested neural network-based models to recognize and count emigrating juvenile river herring in continuous video. Continuous video was collected from an underwater camera installed at Great Herring Pond in Bourne, Massachusetts (USA) between June and November 2017. Our algorithm extracts video frames to assess presence/absence of fish and count numbers of fish emigrating. We used e

Oil well annular cement and casing damage data in mature oil fields undergoing hydraulic fracturing, South Belridge and Lost Hills Oil Fields, California

This data release contains oil well annular cement and casing damage data from parts of the South Belridge and Lost Hills Oil Fields in western Kern County, California. The study area coincides with where groundwater with less than 10,000 milligrams per liter total dissolved solids and outside an exempt aquifer are located overlying oil-producing zones in these fields. In the study areas, hydrauli

USGS National and Global Oil and Gas Assessment Project—Offshore Morocco: Assessment Unit Boundaries, Assessment Input Data, and Fact Sheet Data Tables

This data release contains the boundaries of assessment units, assessment input data, and resulting fact sheet data tables for the assessment of undiscovered oil and gas resources in the offshore salt basin area, Essaouira Province of Morocco. The Assessment Unit is the fundamental unit used in the National and Global Oil and Gas Assessment Project for the assessment of undiscovered oil and gas re

Hepatic gene expression transcript counts in liver samples of American kestrels

A number of brominated flame retardants (BFRs) have been reported to interfere with the thyroid signaling pathway and cause oxidative stress in birds, yet the underlying shifts in gene expression associated with these effects remain poorly understood. In this study, we measured hepatic transcriptional responses of 31 genes in American kestrel hatchlings following in ovo exposure to one of three hi
