Unoccupied Aerial System-mounted image velocimetry and Doppler velocity radar data for computation of river velocity and discharge collected at seven locations in Colorado in 2023: Ground Control
This child item contains information about associating the calibration images and video to real-world distances using ground control points for each field site. The data included here can be used to provide a pixel ground scale distance for each video. Each field site is abbreviated in various files
Unoccupied Aerial System-mounted image velocimetry and Doppler velocity radar data for computation of river velocity and discharge collected at seven locations in Colorado in 2023: Radar Spectra
This child item contains Doppler radar velocimetry spectra measurements for each field site where the radars were deployed. Each field site is abbreviated in various files in this data release. File and folder names quickly identify which site a particular file or dataset represents. The following a
Dust mass and horizontal aeolian sediment flux data from a sampler network on the Colorado Plateau, USA
These data were compiled to assess time series data of aeolian sediment collections across varying climates, vegetation cover, and land uses on the Colorado Plateau. The objectives of our study were to interpret aeolian erosion and deposition processes and measure horizontal sediment flux over the s
iRON_Soil Moisture_Calibrated
**Error has been found in Glenwood Springs station data. The 8in depth soil moisture sensor was mislabeled as the 40in depth sensor and vice versa for data sets uploaded prior to February 2024. Datasets uploaded after Feb 22, 2024 have the sensor labels corrected for all dates going back to installa
Unraveling the ecological and evolutionary impacts of a plant invader on the pollination of a native plant
The results show how the presence of an invasive plant and year-to-year variation in plant-pollinator interactions affect the pollination and components of pollinator-mediated selection in native plants.
Predispersal Seed Predation Obscures the Detrimental Effect of Dust on Wildflower Reproduction
Climate and multiple dimensions of plant diversity regulate ecosystem carbon exchange along an elevational gradient
Abstract The impacts of warming on communities and ecosystems are predicted to be significant in mountain ecosystems because physiological processes, including rates of carbon (C) cycling, are often more temperature‐sensitive in colder environments. Plant biodiversity can also influence C exchange,
Trade-off mitigation: a conceptual framework for understanding floral adaptation in multispecies interactions
ABSTRACTExplanations of floral adaptation to diverse pollinator faunas have often invoked visitor‐mediated trade‐offs in which no intermediate, generalized floral phenotype is optimal for pollination success, i.e. fitness valleys are created. In such cases, plant species are expected to specialize o
Probabilistic Evaluation of Geoscientific Hypotheses With Geophysical Data. Application to Electrical Resistivity Imaging of a Fractured Bedrock Zone
AbstractAs climate changes and populations grow, groundwater sustainability is becoming increasingly important. Hydrogeologic models, which are based on a conceptual understanding of the subsurface, are crucial tools for informing decisions. Conceptual models of the subsurface incorporate knowledge
How do humans impact yellow-bellied marmots? An integrative analysis
While many studies document specific human impacts on the behaviour and physiological responses of wildlife to humans
Understanding pollen specialization in mason bees: a case study of six species
Many bee species are dietary specialists and restrict their pollen foraging to a subset of the available flowers. However, the reasons for specialization—and the reasons certain plant taxa support numerous specialists—are often unclear. Many bees specialize on the plant family Asteraceae, despite ev
Direct Observation of the Depth of Active Groundwater Circulation in an Alpine Watershed
AbstractThe depth of active groundwater circulation is a fundamental control on stream flows and chemistry in mountain watersheds, yet it remains challenging to characterize and is rarely well constrained. We collected hydraulic conductivity, hydraulic head, temperature, chemical, noble gas, and 3H/
Modeling geogenic and atmospheric nitrogen through the East River Watershed, Colorado Rocky Mountains
There is a growing understanding of the role that bedrock weathering can play as a source of nitrogen (N) to soils, groundwater and river systems. The significance is particularly apparent in mountainous environments where weathering fluxes can be large. However, our understanding of the relative co
Estimation of Evapotranspiration Rates and Root Water Uptake Profiles From Soil Moisture Sensor Array Data
AbstractEvapotranspiration is arguably the least quantified component of the hydrologic cycle. We propose two complementary strategies for estimation of evapotranspiration rates and root water uptake profiles from soil‐moisture sensor‐array data. One is our implementation of ensemble Kalman filter (
Mammalian herbivores restrict the altitudinal range limits of alpine plants
Abstract Although rarely experimentally tested, biotic interactions have long been hypothesised to limit low‐elevation range boundaries of species. We tested the effects of herbivory on three alpine‐restricted plant species by transplanting plants below (novel), at the edge (limit), or in the centre
Effect of elevation, season and accelerated snowmelt on biogeochemical processes during isolated conifer needle litter decomposition
Increased drought and temperatures associated with climate change have implications for ecosystem stress with risk for enhanced carbon release in sensitive biomes. Litter decomposition is a key component of biogeochemical cycling in terrestrial ecosystems, but questions remain regarding the local re

Joint Planning Commission, Social Impacts Planning Sub-Committee
It has been decided in the committee that the logic topics to be studied under social impacts include, but are not limited to, housing, social services (police, mental and physical health) education, family and neighborhood relations, and quality of life. Although there will be some overlap with the
