Angel Lichen Moth Abundance and Morphology Data, Grand Canyon, AZ, 2012 Angel Lichen Moth Abundance and Morphology Data, Grand Canyon, AZ, 2012
Two unique datasets on the abundance and morphology of the angel lichen moth (Cisthene angelus) in Grand Canyon, Arizona, USA were compiled to describe the phenology and life history of this common, but poorly known, species. The abundance data were collected from 2012 to 2013 through a collaboration with river runners in Grand Canyon National Park. These citizen scientists deployed...
Flow management for hydropower extirpates aquatic insects, undermining river food websData Flow management for hydropower extirpates aquatic insects, undermining river food websData
Two unique datasets were gathered to document whether flow management for hydropower affects the abundance and diversity of aquatic insect assemblages. The first dataset was collected in Grand Canyon from 2012-2014 by citizen scientists rafting the Colorado River. Simple light traps were set out each night in camp and used to capture the adult life stages of aquatic insects that emerged...
Tsezhin Bii Field and Summary 2004Data Tsezhin Bii Field and Summary 2004Data
These data provide the locational coordinates, soil texture characteristics, plant species occurrence and cover, and vegetation summary characteristics for the Tsezhin bii region in the south-central area of the Navajo Nation in Arizona. They were collected in the fall of 2004 and their subsequent analysis reported in the paper titled 'Vegetation of semi-stable rangeland dunes of the...
Variable Terrestrial GPS Telemetry Detection Rates: Parts 1 - 7Data Variable Terrestrial GPS Telemetry Detection Rates: Parts 1 - 7Data
These data were used to explore environmental effects on fix success rates (FSR) across a wide range of environmental conditions, desert to alpine biomes, and cover the full range of potential data loss (0-100% FSR) for global positioning system (GPS) bias correction of terrestrial GPS-derived, large mammal habitat use. Also, these data were subsequently used to evaluate patterns in...
Riparian vegetation, Colorado River, and climate: five decades of spatio-temporal dynamics in the Grand Canyon with river regulation Riparian vegetation, Colorado River, and climate: five decades of spatio-temporal dynamics in the Grand Canyon with river regulation
These data include image-based classifications of total vegetation from 1965, 1973, 1984, 1992, 2002, 2004, 2005, and 2009, and characteristics of the river channel along the riparian area of the Colorado River between Glen Canyon Dam and Lake Mead Reservoir. Also, these polygon data represent the area inundated by the Colorado River in the aerial imagery from overflight of the Grand...
Flow management and fish density regulate salmonid recruitment and adult size in tailwaters across western North AmericaData Flow management and fish density regulate salmonid recruitment and adult size in tailwaters across western North AmericaData
This data is a compilation of fishery monitoring data collected by state agencies over several decades in tailwaters downriver of dams in Colorado, Utah, Montana, Wyoming, Idaho, New Mexico, Arizona, California, and Oregon. Specifically, the data contained herein is summary data used in four generalized linear mixed models that were developed to assess the biological and hydrologic...
Evaluating rehabilitation efforts following the Milford Flat Fire: Successes, failures, and controlling factorsData Evaluating rehabilitation efforts following the Milford Flat Fire: Successes, failures, and controlling factorsData
Uncontrolled wildfire in arid and semiarid ecosystems has become an increasing concern in recent decades. Active rehabilitation of fire-affected areas is often quickly initiated to minimize long-term ecosystem damage. However, the complex soil-geomorphic-vegetation patterns and low and variable moisture conditions in these regions makes restoration challenging. To further inform these...
