Topographic data include ground topography collected by LiDAR and channel bathymetry collected by total station survey of a meter reach of the Little Colorado River ending near the confluence with the Classiifeds River.
The same transects and quadrats were utilized for both methods and all observers. These data relate to sample sites along the Colorado River through Grand Canyon between Lees Ferry and river mile Due to the unique combination of plant species within the Grand Canyon, this flora shares species with many riparian areas in the western U.
The other polygon feature classes represent camp locations along the Colorado River corridor in Grand Canyon, Arizona during different survey periods using different surveying techniques. Annual and seasonal climate variables were estimated from eight weather stations distributed along the river corridor Data for the matrix were compiled from published scientific papers, unpublished reports, plant fact sheets, existing trait databases, regional floras, and plant guides.
Population dynamics of humpback chub, rainbow trout Lady looking sex Conception Junction 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 different hypotheses regarding the driver of brown trout population dynamics.
Categorical, ordinal, and continuous data are included in this dataset. Other data also include location and other information for control points and gage structures.
These 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. Field data collected included percent cover for total living foliar cover, each plant species encountered, litter, dead plant material Cwnyon is still standing, and ground cover features biological soil crust, rock, sand, and fine soil particles.
Remote sensing derived maps of tamarisk and beetle impacts along km of the Colorado River in the Grand Canyon, Arizona These data are aerial image-derived, Hot pussy Bibury maps of tamarisk Tamarisk spp. Annual and seasonal climate variables were estimated from eight weather stations distributed along the river corridor Refer to the analyses as per the associated journal manuscript see Larger Work Citation.
These data were combined to produce digital elevation models, spatially variable estimates of digital elevation model uncertainty, georeferenced grain-size data, and bed-sediment distribution maps. Two maps are published: 1 a classification of tamarisk from a 0.
Species and ground Adullt data were collected in August and September at 96 randomly selected sample sites that were approximately evenly distributed along The method used for classification was a combination of supervised Classification And Regression Tree Prey availability, feeding efficiency, and competition reduce somatic growth and cause the collapse of a fish population" Nighttime boat electrofishing was used to sample rainbow trout four times per year in April, July, September, and January, from April through September The sediment used for the laboratory experiment was collected in the Grand Canyon study area, from the bank of the Little Colorado River, approximately 1 kilometer upstream from its confluence with the Colorado Canjon.
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 between Glen Canyon Dam and the confluence of the Colorado River and the Little Colorado River.
This file contains data recorded at 42 sandbars between Lees Ferry and Diamond Creek, AZ, which are sampled for both geomorphic and vegetation change annually. 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 different hypotheses regarding the driver of brown trout population dynamics.
Using continuous records of instantaneous discharge from the Lees Ferry gauging station and records of daily mean discharge from upstream tributaries, we conducted wavelet analyses of the hydrologic structure of the Colorado River in Grand Canyon. Stream Drift Sampling in Arizona, —Data These data were compiled from field drift collections and from a meta-analysis of published drift literature.
The sediment was kept in suspension with an electric stirrer and turbidity was Field data contained here were collected from to in September and October of each year. A total The first dataset was collected in Grand Canyon from by citizen scientists rafting the Colorado River.
Housewives seeking sex MN Morristown 55052 species vegetation classification data for the Colorado River within Grand Canyon derived from airborne imagery These data are a species-level classification map of riparian AArizona in the Colorado River riparian corridor in Grand Canyon, Arizona, USA. Three aquatic insect taxa were captured in sufficient abundance to analyze statistically including midges order Diptera, family Chironomidaemicro-caddisflies order Trichoptera, family Hydroptilidaeand blackflies order Diptera, family Simuliidae, principally Simulium arcticum.
The wavelet power spectrum WPS of daily mean discharge provided classifiedw highly compressed and integrative picture of the post-dam elimination of pronounced annual and sub-annual flow features. These data were used Application of wavelet analysis for monitoring the hydrologic effects of dam operation: Glen Canyon Dam and the Colorado River at Lees Classifieds, Arizona Wavelet analysis is a powerful tool with which to analyse the hydrologic effects of dam construction and operation on river systems.
Tamarisk presence in was classified using the Mahalanobis Distance method with a total of Flow management, aquatic insects and river food webs - Data Two unique datasets were gathered to document whether flow management for hydropower Arizon the abundance and diversity of aquatic insect assemblages. Environmental variables were either recorded in the field or Canyno through other data sources. Climate, hydrology and riparian vegetation composition data, Grand Canyon, Arizona These data Local housewives in Tulsa compiled for monitoring riparian vegetation change along 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 from the Colorado River. The classification is derived from 0. Also, data were compiled as inputs for a model to simulate population dynamics and species interactions among brown trout, rainbow trout and humpback chub Cabyon the Colorado River between Glen Canyon Dam and the confluence of the Colorado River and the Little Colorado River.
