Traits and Factors Catalog (TRAFAC): Conifer specialists of North America Traits and Factors Catalog (TRAFAC): Conifer specialists of North America

These data were compiled in support of the 'Predicting the next high-impact insect invasion: Elucidating traits and factors determining the risk of introduced herbivorous insects on North American native plants' project, supported by the U.S. Geological Survey John Wesley Powell Center for Analysis and Synthesis. The project working group compiled data for non-native insects herbivorous...

Vegetation cover and composition data in environments surrounding uranium mines in the Grand Canyon ecosystem, USA Vegetation cover and composition data in environments surrounding uranium mines in the Grand Canyon ecosystem, USA

This data package contains the final combined field sampling data collected by the USGS July 2013 and July-August 2015 at three active uranium mines (Canyon Rim Mine, Pinenut Mine, and Arizona 1 Mine) as well as two reference sites (Little Robinson Tank and EZ2 Pipe) in northwestern Arizona. Vegetation and soils were assessed by using line-point intersect (LPI) methods and estimates of...

Meteorological measurements from five locations within the Badger Wash study area near Mack, Colorado (ver. 3.0, September 2024) Meteorological measurements from five locations within the Badger Wash study area near Mack, Colorado (ver. 3.0, September 2024)

These data are records collected from an automated weather station and four stand-alone tipping bucket rain gauges each with their own data logger that were in operation between February 2005 and December 2019 in the Badger Wash Study Area near Mack, Colorado as part of a larger project funded by the Bureau of Land Management. These files are hourly-interval data from the automated...

Marginalizing Bayesian population models - data for examples in the Grand Canyon region, southeastern Arizona, western Oregon USA - 1990-2015 Marginalizing Bayesian population models - data for examples in the Grand Canyon region, southeastern Arizona, western Oregon USA - 1990-2015

These data were compiled here to fit various versions of Bayesian population models and compare their performance, primarily the time required to make inferences using different softwares and versions of code. The humpback chub data were collected by US Geological Survey and US Fish and Wildlife service in the Colorado and Little Colorado Rivers from April 2009 to October 2017. Adult...

Stand density and climate data in the Taylor Woods study area (Fort Valley Experimental Forest) on the Colorado Plateau in Northern Arizona, 1961-2011 Stand density and climate data in the Taylor Woods study area (Fort Valley Experimental Forest) on the Colorado Plateau in Northern Arizona, 1961-2011

These data were compiled for research pertaining to the effects of stand density on growth rates in semi-arid forests. Increasing heat and aridity in coming decades is expected to negatively impact tree growth and threaten forest sustainability in dry areas. Maintaining low stand density has the potential to mitigate the negative effects of increasingly severe droughts by minimizing...

Pinyon and Juniper location data, including a literature review citation list of Pinyon-Juniper systems from 1909 to 2018 Pinyon and Juniper location data, including a literature review citation list of Pinyon-Juniper systems from 1909 to 2018

These data were compiled for a comprehensive review of pinyon-juniper communities including Pinus edulis, Pinus monophylla, Juniperus osteosperma, Juniperus monosperma, and Juniperus scopulorum. Compiled are a list of references cataloged by the topic of interest resulting from the literature search. The characterization for each reference includes the focal species, descriptions of the...

Channel narrowing data for the lower Green River in the Canyonlands region, Utah, USA Channel narrowing data for the lower Green River in the Canyonlands region, Utah, USA

The 'Channel Width' shapefile data are measurements of the active channel width of the Green River at 1-km intervals in and near Canyonlands National Park, Utah. The active channel was defined as the area of the wetted, or inundated, channel as visible on aerial photographs plus the area of bare (free of vegetation) sand and gravel bars. The active channel for each aerial photograph...

Hilaria jamesii data for the Colorado Plateau of the southwestern United States Hilaria jamesii data for the Colorado Plateau of the southwestern United States

These data were compiled to investigate the demographic, phylogeographic, and adaptation history of Hilaria jamesii. The data release consists of three tab delimited text files that may be used to infer population structure or putative adaptive loci (hija_adaptation_dataset.stru), relationships among sampling localities (hija_phylogeny_dataset.phylip), or genetic diversity statistics...

Fish tissue mercury and selenium concentrations in Upper Colorado River Basin: 1962-2011 Fish tissue mercury and selenium concentrations in Upper Colorado River Basin: 1962-2011

These data were compiled to study mercury and selenium concentrations in fish species and assemblages in lotic waterbodies across the Upper Colorado River Basin. Data were compiled from State and Federal agencies. This data table contains raw concentration data, as well as standardized concentrations corrected for differences based on sample type (i.e., tissue type), species-specific

Insect catch rates and angler success data during Bug Flows at Glen Canyon Dam, 2012-2018 Insect catch rates and angler success data during Bug Flows at Glen Canyon Dam, 2012-2018

These data were compiled to evaluate the effects of low steady weekend flows on emergent aquatic insects during the first year of experimental Bug Flows below Glen Canyon Dam (2018) and recreation in Glen Canyon in the second year of Bug Flows (2019). Bug Flows are experimental flows that were released from Glen Canyon Dam in 2018 and 2019. The flows consist of low steady flows on...

Calcium, magnesium and total dissolved solids data as well as modeled salinity and mass balance estimates for Lake Powell, 1952-2017 Calcium, magnesium and total dissolved solids data as well as modeled salinity and mass balance estimates for Lake Powell, 1952-2017

These data were compiled to quantify the role of Lake Powell in modulating salinity and reducing overall salt flux from the Upper Colorado River Basin downstream. In addition, these data were used to infer summertime calcite precipitation in Lake Powell (the major proposed sink for salt within the system). The Lake Powell Calcium Magnesium data contains summertime surface water calcium...

Dataset for plant production responses to climate across water-limited regions Dataset for plant production responses to climate across water-limited regions

This dataset was constructed from readily available open source climate and vegetation data, like Landsat. This dataset represents the vegetation and climate conditions for a large number of points across the major deserts of the SW USA. The dataset was constructed in order to use the climate pivot point approach (Munson et al. 2013) at the landscape level. Originally this dataset was...
