Sapflow and xylem water isotopes from Snodgrass Mountain, East River Watershed, Colorado USA. Space and time dynamics of transpiration in the East River watershed: biotic and abiotic controls
This dataset includes sapflux and stable water isotopes of soil water and xylem water for aspen, fir and spruce trees along the Snodgrass Mountain transect in the East River Watershed, Colorado USA. The purpose of generating this dataset was to understand: (1) the total flux of water being used by t
Data from: “Significant stream chemistry response to temperature variations in a high-elevation mountain watershed”
High-elevation mountain regions, central to global freshwater supply, are experiencing more rapid warming than low-elevation locations. High-elevation streams are therefore potentially critical indicators for earth system and water chemistry response to warming. Here we present concerted hydroclimat
Stream discharge data collected within the East River, Colorado for the Lawrence Berkeley National Laboratory Watershed Function Science Focus Area (water years 2019 to 2020).
This data package contains East River, Colorado stream discharge and temperature data for water years 2019 to 2020. This data were collected to understand hydrological processes occurring in the East River Watershed, Colorado, which is part of the Lawrence Berkeley National Laboratory Watershed Func
ATS (Advanced Terrestrial Simulator) integrated hydrology and reactive transport model output in Copper Creek, Colorado.
This dataset is generated using the ATS (Advanced Terrestrial Simulator) model at Copper Creek, Colorado, the largest catchment in the East River watershed. ATS is an integrated hydrology and reactive transport model to simulate the Concentration-Discharge (C-Q) relationship, and is used to quantify
QA/QC of the East River, Colorado, discharge and geochemical time series datasets (Almont, BCC, and Pump House) to be used for modeling of hydrogeochemical balance.
The following datasets were QA/QC-ed (Quality Assurance/Quality Control): 1. Brush Creek Confluence (BCC) discharge data (from Helen Malenda, USGS, Colorado School of Mines), which were calculated using the pressure transducer data and rating curves. The original 15 min time series data were present
Colorado Elevation Gradient Snowmelt Manipulation Plant Phenology 2017-2018.
This dataset includes observations of plant phenology at five locations along an elevation gradient in Crested Butte, Colorado. Observations occurred over the years 2017 and 2018. Observations taken in 2018 are associated with an experimental early snowmelt manipulation. The file PhenologyData_compl
Lead isotopic compositions of airborne particulates collected from snow and from dry deposition in the East River Watershed, Colorado and at the Southern Sierra Critical Zone Observatory, California.
The data set consists of lead (Pb) isotopic ratios (206Pb/207Pb and 208Pb/207Pb, as well as 206Pb/204Pb, 207Pb/204Pb, 208Pb/204Pb) for particulate samples collected from snow and dry deposition. This was part of a study (O Day et al. 2020) that was looking at the speciation of phosphorous in splits
Trichome density differences in Boechera stricta across an elevational gradient.
Insect herbivores consume plant tissue, reducing plant fitness in the process. In response, plants have evolved a variety of mechanical and chemical defenses to protect themselves. This paper focuses on trichomes, which are hair-like appendages that extend from leaf tissues, and plants use them as a
Phenology of Arbuscular Mycorrhizal fungi and Dark Septate Endophytes across an elevation gradient.
Arbuscular Mycorrhizal Fungi (AMF) and Dark Septate Endophytes (DSE) participate in symbiotic relationships with host plants in the Rocky Mountains. The effects of plant-host phenology on these fungal symbionts is important in our understanding of how climate changes effects on plants will change th
Temporal Patterns in Foraging activity of Colorado Montane Bumblebees.
Aboveground and belowground traits of dominant and sub-dominant species along an elevational gradient.
Selection on floral traits of Linus lewisii along an elevational gradient.
Frost Sensitivity of Subalpine Plants in the Colorado Rocky Mountains: The Effects of Seasonality, Water Content, and Phylogeny
Our study examined the frost sensitivities of subalpine flowering plants near the Rocky Mountain Biological Laboratory, in Gothic, CO. Most studies on the impacts of climate change have focused on the effects of temperature warming and how it affects species. Our study examined the frost sensitiviti
Pollen allelopathy: Taraxacum officinale pollen depresses seed set of montane wildflowers
Responses of high-altitude graminoids and fungal fungi to 20 years of experimental warming
Yeasts in nectar enhance male fitness in a montane perennial herb
Floral nectar of many plant species is prone to colonization by microbial organisms such as yeasts. Their presence and metabolism of nectar chemical components have the potential to modify a suite of floral traits important for pollinator attraction, including nectar quality and scent. However, stud
