To determine how initial length affects survival of captively-reared juvenile suckers, we introduced Passive Integrated Transponder (PIT) tagged juvenile suckers into three net pens in Upper Klamath Lake. The suckers originated from the U.S. Fish and Wildlife Service's Sucker Assisted Rearing Program in Klamath Falls, Oregon, which rears suckers collected as larvae in Upper Klamath Lake...

This data set contains fission track data and associated ages of apatite from igneous and sedimentary rocks, U-Pb isotopic data and associated ages of zircon from a subset of the igneous rock samples, and U-Pb isotopic data and associated ages of detrital zircon from a subset of the sedimentary rock samples. All samples were collected from the region surrounding Lake Clark and Lake...

A comprehensive study to evaluate water-quality trends in the International Souris River Basin, Saskatchewan and Manitoba, Canada and North Dakota, United States was completed by the U.S. Geological Survey (USGS) in cooperation with the International Joint Commission. In this dataset all files necessary to run trend models and produce results published in U.S. Geological Scientific...

Body condition indices and related metrics can help assess habitat quality and other ecological processes, and ideally these metrics are based on measures of lipids directly extracted from the species of interest. In recent decades, barred owls (Strix varia) have become a species of conservation concern as they invaded older forests of the U.S. Pacific Northwest, and caused population...

These data reflect nuclear microsatellite genotypes for specimens of yellow rails (Coturnicops noveboracensis) sampled in 2005-2008. Data from six populations are included.

The dataset includes several measurements collected for two complementary phases of a Sandberg bluegrass restoration project. In the first phase of the project, percentage of vegetation and soil surface cover (e.g. soil, rock) were measured within each of 20 treatment plots (described in the following section) using the Line Point Intercept (LPI) method (Herrick et al. 2005) from 2019...

This dataset contains biocrust lichen and moss cover at 186 plots at Horse Heaven Hills in Washington, USA. These data were measured by Jeanne Ponzetti in 1999 and remeasured by Heather Root in 2020. In addition to the biocrust data, we include site data such as elevation, location, wildfire history, and cover classes of dominant plants, rock and soil.

LiDAR scans were taken using a tripod mounted Riegl VZ-400 scanning LiDAR. The tripod was set up such that the scanner was between 1.5 and 2.5 m tall. The VZ-400 is a near infrared (1550 nm) scanner. Geometric control was achieved using a pair of Trimble RB GPS antennae, one mounted on the LiDAR scanner (rover) and the other setup as a base station. Before taking a LiDAR scan, the VZ-400...

This data release contains gridded aeromagnetic data from a dataset that merges two aeromagnetic surveys of northeastern California. Data from the Alturas and Burney surveys were gridded and merged to provide a continuous, detailed aeromagnetic dataset of the region. The merged dataset was then corrected for the inclination of the Earth's magnetic field (reduced to pole or rtp); match...

Sonic velocity and density well logs in the Central Coast Ranges in California were digitized by hand. These logs are available as scanned files (pdfs and tiffs) on the California Division of Oil, Gas, and Geothermal Resources website and the data consist of interval transit times and bulk density measured downhole in oil and gas wells in the region. Sonic velocity data were also...

In coastal subarctic environments such as the fjords of Southeast Alaska, tidewater glaciers can control local hydrology, climatic patterns, ecology, and geologic hazards like landslides and consequent tsunami waves. Documenting and studying glacial retreat in fjords can help scientists understand the dynamic systems that are intrinsically tied to glacial ice processes and forecast...

These data are nutrition, economic value, and climate vulnerability of inland recreational consumption by country. The dietary contribution is measured as calcium, omega-3 long-chain polyunsaturated fatty acids docosahexaenoic acid and eicosapentaenoic acid (hereafter referred as DHA+EPA), iron, protein, vitamin B12, and zinc supply. The economic contribution is measured as total...
