Dissolved Oxygen and Temperature Data from the Hyporheic Zone of the East River Watershed July 2017 to October 2018
Dissolved oxygen (DO) is critical for aquatic ecosystems. Our focus is on the long-term DO dynamics in hyporheic zone of rivers, which are a function of both transport (hydrologic exchange between river and hyporheic zone) and uptake by biogeochemical reactions or respiration. The study site is the
Community-level flowering & fitness data across an elevational gradient, Rocky Mountain Biological Lab, 2021-2022
We collected data at three sites in Washington Gulch near the Rocky Mountain Biological Laboratory (RMBL, Gothic, Colorado, USA) from June to August 2021 and 2022. RMBL is located in the East River valley of the West Elk mountains, approximately 10 kilometers from Crested Butte, Colorado. Study site
Radon Isotopes and Stable Water Isotopes from Coal Creek Watershed, Colorado (2021)
The radon isotope and stable water isotope data for Coal Creek Watershed, Colorado, consists of d2H, d18O, and 222Rn values from samples collected at 8 stream location along Coal Creek, samples from 7 groundwater springs within the watershed, and precipitation isotope samples collected by Next Gener
Groundwater level elevation and temperature data, Oct 2018-Dec 2021, Slate River Floodplain, Crested Butte, CO.
This data package includes a time series of water level and temperature measurements from October 2018 to December 2021 in groundwater and surface water from the Slate River floodplain outside Crested Butte, CO, a focus field site for the SLAC Floodplain Hydro-Biogeochemistry SFA. The data was gener
Cation Data for the East River Watershed, Colorado (2014-2021)
This data package contains mean values for cation concentration for water samples taken from the East River Watershed in Colorado. Inductively coupled plasma mass spectrometry (ICP-MS) has been used to measure the concentrations of 37 elements of interest simultaneously for the East River Watershed,
Correlation of leaf and community traits and various spectra in meadows along an elevation gradient
The capabilities of remote sensing technology are advancing rapidly, and with it, the applications of those technologies are also advancing. Indices such as Normalized Difference Vegetation Index (NDVI) have long been used to determine vegetative health, but no direct measurements have been made to
Do bees show response diversity to environmental variables in a montane ecosystem?
With climate change threatening a wide variety of organisms and ecosystems, expanding our knowledge of how they will respond is vital for making predictions and conservation decisions. One important group of organisms impacted by climate change is the wild bees, which provide an essential ecosystem
Analyzing the effect of climate change on <i>Boechera stricta</i> seed germination and fitness along an elevational gradient
Climate change alters many biotic and abiotic factors in environments around the world. At higher elevations in particular, climate change brings warmer mean temperatures, reduced snowpack, earlier snowmelt, and more extreme drought. In this study, we analyzed the effect of early snow removal on Boe
Sixty-five years of change in montane plant communities in Western Colorado, USA
Documenting and predicting patterns of vegetation change over time are challenging due to a lack of sufficiently detailed historical data for comparison. Montane plant communities are expected to respond to anthropogenic disturbance, including climate change, in complex ways dependent on component s
Reconstruction and spatial analysis of alpine treeline in the Elk Mountains, Colorado, USA
Natal philopatry varies with larval condition in salamanders
An important, long-lasting role of the natal environment on reproductive site selection is suggested, and the conditions experienced in early development can strongly affect reproductive behaviors across the life cycle, as well as differences in philopatry based on natal pond.
Abiotic mediation of a mutualism drives herbivore abundance.
Historical changes in thermoregulatory traits of alpine butterflies reveal complex ecological and evolutionary responses to recent climate change
Background: Trait evolution and plasticity are expected to interactively influence responses to climate change, but rapid changes in and increased variability of temperature may limit evolutionary responses. We use historical specimens to document changes in the size and thermoregulatory traits of a
Frost sensitivity of leaves and flowers of subalpine plants is related to tissue type and phenology.
Environmental drivers of plant community composition in subalpine and alpine fens of the San Juan Mountains, Colorado, USA
Fens are a widely distributed type of wetland worldwide and offer vital habitat for plant and animal species in the Rocky Mountains. Fens support a high biodiversity of flora and fauna given the proportionally small space they occupy on the landscape, often serving as refugia for disjunct plant spec
Quantifying within-season floral trait distributions of flowers in Colorado Rocky Mountain sub-alpine dry meadows.
Causes and consequences of dominant and subdominant plant species effects on ecosystem function: using above-and belowground traits in an alpine meadow system
While there has been extensive studies done on how dominant affect community dynamics and ecosystem function, fewer studies address the relative influence of dominant vs. subdominant species to affect systems. Further, not enough studies have been done addressing the role of dominant vs. subdominant
