DATA RELEASE - Stream Drift Sampling in Arizona, 2014

Data were compiled from field drift collections and from a meta-analysis of published drift literature. Field data were collected in 2014 from the Colorado River downstream of Glen Canyon Dam, Arizona. Data represent flow meter measurements taken at the mouth and adjacent to a drift net, and suspended solids concentrations collected by the drift net, over varying net deployment durations.

Full annual cycle bioenergetics model of migration applied to Galapagos tortoises—Data

Ambient-shade temperature was measured every 4 h with iButton thermochrons (Maxim Integrated Products, Inc., Sunnyville, CA, USA) placed at 1m above-ground level for a previous paper (Blake et al., 2012 – DOI 10.1111/1365-2656.12020).

Riparian vegetation classification of the Colorado River Corridor, Grand Canyon, Arizona, 2013—Data

These data are classification maps of total riparian vegetation along the Colorado River in Grand Canyon from Glen Canyon Dam to Pearce Ferry in Arizona. The data are derived from interpretation of multispectral high resolution airborne imagery that was acquired in May 2013. The total vegetation data have the same 0.2-meter ground resolution as the imagery. These data have not undergone a...

Plant functional traits, Colorado River, Grand Canyon, 2012-2014—Data

These data were compiled or measured (depending on the trait) for 110 plant species which were documented in vegetation monitoring surveys in years 2012-2014 along the Colorado River through Grand Canyon National Park. New trait data was collected forspecific leaf area, stem specific gravity, δ13C, δ15N, percent carbon and nitrogen, and carbon/nitrogen ratio. Seed mass and...

Variable Terrestrial GPS Telemetry Detection Rates: Parts 1 - 7—Data

Studies utilizing Global Positioning System (GPS) telemetry rarely result in 100% fix success rates (FSR). Many assessments of wildlife resource use do not account for missing data, either assuming data loss is random or because a lack of practical treatment for systematic data loss. Several studies have explored how the environment, technological features, and animal behavior influence...

Riparian Vegetation and Environmental Variables, Colorado River, 2014—Data

These data consist of species relative cover, percent cover of dead plant material, percent cover of soil and rock, and a variety of broad - and local- scale environmental variables. These data relate to sample sites along the Colorado River through Grand Canyon between Lees Ferry and river mile 245. The plant and ground cover data included here were originally collected as a part of annual...
