Data

Staff of USGS Science Centers in Region 7: Upper Colorado Basin collect a wide variety of natural resource data types including spatial, geologic, hydrologic, and biologic. Data included in USGS-series publications that are not publicly available in USGS databases are published in Data Releases. Short descriptions and links to Data Releases produced by Region 7 Science Centers are shown below.

Flea abundance and body condition data for black-tailed prairie dogs on sites treated and not treated with "FipBit" fipronil pellets, South Dakota, 2018-2020

Flea abundance and body condition data for black-tailed prairie dogs on sites treated and not treated with "FipBit" fipronil pellets. We sampled prairie dogs at Conata Basin, Buffalo Gap National Grassland, and Badlands National Park, South Dakota, USA. We sampled fleas from live-trapped prairie dogs during June-October 2018, May-October 2019, and July-August 2020. Prairie dogs were sampled before

Supporting data for Physical and chemical evidence for an aeolian component of paleowetland deposits

The Las Vegas Formation (LVF) is a well-characterized sequence of groundwater discharge (GWD) deposits exposed in and around the Las Vegas Valley in southern Nevada. Nearly monolithologic bedrock surrounds the valley and provides an excellent opportunity to test the hypothesis that GWD deposits include an aeolian component. Mineralogical data indicate that the LVF sediments are dominated by carbon

Monitoring mortality of brown treesnakes fed an oral toxicant (acetaminophen) in an external bait placement dosing technique in the laboratory, 2017

Accidentally introduced to Guam, the brown treesnake (BTS) has extirpated nearly all native forest birds and imposed cost millions of dollars in economic damages annually. Acetaminophen is a safe and effective oral toxicant for invasive BTS, and an automated aerial delivery system (ADS) has been developed for landscape-scale distribution and snake suppression. An 80 milligram dose has proven 100%

Chorus frog density and population growth, Cameron Pass, Colorado, 1986-2020

We investigated population dynamics in chorus frogs (Pseudacris maculata) relative to extrinsic (air temperatures and snowpack) and intrinsic (density dependence) characteristics at 2 sites in Colorado, USA. We used capture-mark-recapture (cmr) data (i.e., 1 or 0, provided here) and a Bayesian model framework to assess our a priori hypotheses about interactions among covariates and chorus frog sur

Data for a lab study of the effects of diet variability on the interactions between a Lepidopteran herbivore and its parasitoid

Data were collected from two laboratory rearing experiments conducted in 2018 of Trichoplusia ni caterpillars that had been parasitized by Copidosoma floridanum parasitoids. In the first experiment, parasitized caterpillars were fed artificial diets spiked with increasing concentrations of the phytochemical xanthotoxin in order to assess the effect of xanthotoxin on parasitoid success. In the seco

Repeat microgravity data from Mesilla Valley, New Mexico, 2016-2018

This dataset represents the network-adjusted results of relative- and absolute-gravity surveys. Relative-gravity surveys were carried out using a Zero Length Spring, Inc. relative-gravity meter. The effect of solid Earth tides and ocean loading were removed from the data. Instrument drift was removed by evaluating gravity change during repeated measurements at one or more base stations. Absolute-g

Compiled reference list to support reservoir thermal energy storage research

This text file (Reference_List_V1.txt) lists references that describe relevant characteristics for reservoir thermal energy storage (RTES) research in the United States. References are grouped by corresponding city, including: Albuquerque, New Mexico; Charleston, South Carolina; Chicago, Illinois; Decatur, Illinois; Lansing, Michigan; Memphis, Tennessee; Phoenix, Arizona; and Portland, Oregon. The

Visual Surveys and Morphometrics of Brown Treesnakes in Mariana Swiftlets caves on Guam

Visual survey data for brown treesnakes from caves with and without swiftlets. Each record (line) represents the snake sightings that occurred during a block of time, typically 1 hour at one site by searcher(s) during one search (i.e. one date). Snakes removed from caves and adjacent areas during visual surveys were then necropsied. Each record (line) represents necropsy results for a given indivi

Salvator merianae trapping in Georgia, USA

Argentine Giant Tegu lizard (Salvator merianae) trap effort and count data collected in southern Georgia, USA in 2019. Non-target species associated with the traps were also documented, as were type of bait used and condition of the traps during trap checks.

Presence of erosional features and cover of grasses, forbs, and bare ground on fields enrolled in grassland, wetland, and wildlife practices of the Conservation Reserve Program in the central and western United States from 2016 to 2018

Data included in this data set are from in-field and edge-of-field surveys that recorded the presence of erosional features and cover of vegetation and bare ground on 1786 Conservation Reserve Program fields across three types of conservation practices (grassland, wetland, and wildlife). Field sampling data were recorded across six US Department of Agriculture Farm Production Regions (Corn belt, L

Data release for Climatically driven displacement on the Eglington fault, Las Vegas, Nevada, USA

The Eglington fault is one of several intrabasinal faults in the Las Vegas Valley, Nevada, USA, and is the only one recognized as a source for significant earthquakes. Its broad warp displaces Late Pleistocene spring deposits of the Las Vegas Formation, which record hydrologic fluctuations that occurred in response to millennial- and submillennial-scale climate oscillations throughout the late Qua

Data on the effects of deltamethrin and fipronil on black-tailed prairie dog ectoparasites, South Dakota, USA, 2018-2019

Data were collected to investigate effects of deltamethrin and fipronil on ectoparasites from black-tailed prairie dogs in South Dakota, USA. In late-July 2018, we treated 3 sites with 0.05 percent deltamethrin dust and 5 sites with host-fed 0.005 percent fipronil grain. Three non-treated sites functioned as experimental baselines. We collected ectoparasites before treatments (June-July 2018) and
