Optimizing Field-linked simulations of dry season uptake and monsoon infiltration within an aspen-mixed conifer forest
Climate models forecast that headwater catchments in the western U.S. will undergo a reduction in snowpack, early season snowmelt, and increases in evapotranspiration. The resulting extended dry season will stress vegetation in mountainous watersheds throughout the Upper Colorado River Basin. We inv
Effects of Temperature and Competitor Abundance on Bumble Bee Foraging
The role of plant-pollinator interactions is essential for successful plant and pollinator reproduction, thus influencing community assembly of both plants and animals within an ecosystem. Pollinators exhibit competitive behavior in order to collect adequate quantities of pollen and nectar, and bees
The Effects of Temperature and N:P Ratios on Didymo Algae Growth
Didymosphenia geminata (didymo) is a species of algae that is native to North America, but has been producing unprecedented blooms during the last several decades. Climate change and nitrogen deposition are two hypothesized drivers of this phenomenon. The purpose of this research project is to bette
Solitary bee genera differ in foraging activity timing and temperature; Evidence of a seasonal dietary shift in Hoplitis fulgida
Global warming, and exacerbated warming temperatures with humane activity, could impose novel conditions on the lives of many organisms. Of those, the behaviors and diets of solitary bees face adaptive stress as their optimal foraging conditions and preferred floral resources fluctuate. Trap nests m
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

Water Vapor Isotopic Composition During SAIL
Measurements of the stable isotopic composition of water vapor were collected between 21 November 2022 and 1 June 2023 at the SAIL campaign main site in Gothic Colorado. The data were obtained using a Los Gatos Research Triple Water Vapor Isotopic Analyzer from a heated and insulated inlet mounted o
VISSS Raw data from SAIL at Gothic from November 2022 to June 2023
A Video in situ Snowfall Sensor (VISSS) records shadow images of precipitating hydrometeors from two perspective at a 90 degree angle with a frequency of 140 Hz. From this, hydrometeor properties such as particle size, shape, complexity, degree of riming, and fall velocity can be derived. The VISSS
WARM experiment Soil Microbial Function, RMBL Colorado, 2021
We examined how abiotic (warming), and biotic (presence of dominant plant species) factors interact to affect soil microbial processes in montane meadow ecosystems at high and low elevations at the WaRM experimental sites near the Rocky Mountain Biological Laboratory in Colorado in the West Elk rang
Colony counts and environmental covariates of the American white pelican colony on Gunnison Island, UT, USA
Annual colony counts of American white pelican (Pelecanus erythrorhynchos) at Gunnison Island, Utah, USA, and selected environmental covariates hypothesized to influence colony population dynamics at this location. Environmental covariates include mean springtime Great Salt Lake water levels, minimu
Global Bee Interaction Data
Last modified: July 3, 2024 IntroductionThis dataset comprises all bee interactions indexed by Global Biotic Interactions (GloBI; Poelen et al. 2014). It is published quarterly by the Big Bee Project (Seltmann et al. 2021) to summarize all available knowledge about bee interactions from natural hist
Percent plant cover, Warming and Removal in Mountains (WaRM) experiment, Rocky Mountain Biological Laboratory, 2013-2022
These data were collected from 2013 to 2022 near the Rocky Mountain Biological Laboratory in Colorado. They are from a climate change experiment that manipulated temperature using open-top chambers to passively warm the air and plant community composition by removing the dominant species in a factor
Data from: Variation in season length and development time is sufficient to drive the emergence and coexistence of social and solitary behavioral strategies
Season length and its associated variables can influence the expression of social behaviors, including the occurrence of eusociality in insects. Among bees, ants, and wasps, social behaviors can vary widely across environmental gradients, both within and between different species. While numerous the
Upland Vegetation and Soils Monitoring for the Northern Colorado Plateau Network: 2009-2023 - Data Package
Uplands are land areas lying above the elevation where flooding generally occurs—areas found beyond riparian zones. Uplands represent the vast majority of land area in the Northern Colorado Plateau Network (NCPN), and include rock outcrops, badlands, shrublands, grasslands, woodlands, and forests. U
NOAA GML and CIRES/Uni. of Colorado-Boulder Ceilometer Cloud Data Products at Kettle Ponds (CKP) for SPLASH
Cloud base height / vertical visibility and attenuated backscatter coefficient profiles from NOAA GML's Vaisala CL51 ceilometer deployed at Kettle Ponds (CKP). Data have been sampled to nearest 1-min. See Readme document for details.
Data from: A multi-year case study highlighting the influence of hydrological conditions on epidemic dynamics in a natural plant pathosystem
The scale of influence of hydrological and thermal conditions on disease remains uncertain for most wild plant pathosystems, thus restricting our ability to predict the impacts of climate change. Analysis of the spatiotemporal spread of a fungal rust pathogen throughout four naturally occurring flax
