Laboratory Predation Data (various nonnative warm-water sport fishes), Arizona

These data were compiled to evaluate the potential impact various environmental conditions may have on native fish populaitons through predation. Introduced warm-water sport fishes present a high predation risk for juvenile native fishes, but observations of juvenile native fish surviving and recruiting in some rare cases led us to question what environmental conditions might be responsible...

Erosion and Rehabilitation Data, Bandelier National Monument, New Mexico, USA

These data were compiled for a restoration experiment testing the regenerative and functional response of biocrust inoculum reintroduced to a field setting. Regenerative traits measured included measurements of biocrust cover, chlorophyll content, and the roughness of the soil surface. Functional traits measured included nutrient cycling and soil stability. Additionally, these data were...

Riparian vegetation data used for comparing sampling methods along the Colorado River, Grand Canyon, Arizona

These data were collected as part of a methodological comparison for collecting riparian vegetation data. Two common methods for collecting vegetation data were used: line-point intercept and 1m2 ocular quadrats (visual cover estimates). At each site and transect, both methods were used to collect cover and composition data by four different observers. The same transects and quadrats were...

Long-term precipitation reduction experiment in the Colorado Plateau - Survival and mortality data from 2010 to 2018

From 2011-2018 USGS biologists recorded vegetation and biological soil crust (BSC) cover by species and tracked survival of tagged individual plants (388 in total) across 40 locations where paired experimental plots had been installed in 2010. Plant cover was visually estimated using four 75 x 100 cm survey frames. Each site contained a two plots measuring 1.5 by 2.0 meteres: a control plot...

DATA RELEASE - Spatial distribution and risk analysis data for diamond-backed terrapins relative to crab trapping, Savannah Coastal Refuge Complex, USA - Data

The data collected during the systematic inventory of diamond-backed terrapins includes information on terrapin detection in tidal creeks on refuges, crab pot numbers and locations, and a variety of environmental-, location-, and observer-related variables to examine the effects of both environmental conditions and observer bias on terrapin detection.

DATA RELEASE - Occurrence records and vegetation type data used for species distribution models in the western United States - Data

These data are species distribution information assembled for assessing the impacts of land-use barriers, facilitative interactions with other species, and loss of long-distance animal dispersal on predicted species range patterns for four common species in pinyon-juniper woodlands in the western United States.

DATA RELEASE - Aeolian mass flux, rangeland monitoring site, and unpaved road reach data - Data

These data were compiled for monitoring and analyzing the amount of windblown (aeolian) sediment at 100 cm height near Moab, UT. Big Springs Number Eight (BSNE) field aeolian passive sediment traps are summarized by location and time period in shapefiles. Shapefiles also include attributes used to analyze patterns in the aeolian transport.

DATA RELEASE - Climate, hydrology and riparian vegetation composition data, Grand Canyon, Arizona - Data

These data were compiled for monitoring riparian vegetation change along the Colorado River. This file contains data recorded at 42 sandbars between Lees Ferry and Diamond Creek, AZ, which are annually sampled for both geomorphic and vegetation change. Field data contained here were collected from 2012 to 2016 in September and October of each year.

DATA RELEASE - Simulated Soil Water Potential in National Parks and Monuments of the Southern Colorado Plateau, 1915-2099—Data

These data were simulated using the SOILWAT model and were intended to characterize soil-water conditions at different ecological sites on the southern Colorado Plateau. The sites simulated correspond with Inventory and Monitoring plots established by the National Park Service’s Southern Colorado Plateau Network.

DATA RELEASE - The influence of water temperature on salmonid recruitment and adult size in tailwaters across western North America—Data

These data were used to examine drivers behind changes in water temperature downriver of dams across the western U.S. from 1995-2015 and the influence of such changes on rainbow trout recruitment and rainbow and brown trout adult length.

DATA RELEASE - Population dynamics of humpback chub, rainbow trout and brown trout in the Colorado River in its Grand Canyon Reach: modelling code and input data

These data were compiled to fit an integrated population model of brown trout in the Glen Canyon reach of the Colorado River and test hypotheses regarding the driver of brown trout population dynamics. Also, data were compiled as inputs for a model to simulate population dynamics and species interactions among brown trout, rainbow trout, and humpback chub in the Colorado River.
