Groundwater elevation data for monitoring wells within the East and Taylor River basins, Colorado (USA)
This dataset is comprised of temporal variations in groundwater elevation data for the 24 monitoring wells located throughout the East River watershed. Seasonal to annual variations in groundwater elevations are a critical property of mountainous watersheds needed to understand both hydrological and
Stream bed topography in 2016 at the Lower Montane site in the East River Watershed, Colorado
This dataset contains stream bed topography data from the Lower Montane site in the East River Watershed, Colorado. It is intended to support hydro-biogeochemical analyses for the Watershed Function Scientific Focus Area (SFA). The stream bed was surveyed using a RTK-GPS (Real-Time Kinematic Global
Soil moisture and temperature from 2019 to 2024 along northeast- and southwest-facing hillslopes at the Lower Montane site in the East River Watershed, Colorado
Soil moisture, temperature, and electrical conductivity have been monitored at multiple depths (between 10 and 50 cm) at 4 locations along a northeast-facing slope and 3 locations on the opposite southwest-facing slope at the Lower Montane site in the East River Watershed, Colorado, from Oct 2019 to
Metagenome-assembled genomes measured at 3 depths during snowmelt period in East River, CO (March, May, and June, September 2017)
Snowmelt is a critical biogeochemical period that accounts for large nitrogen (N) export events from high-elevation watersheds. Soil microbial populations bloom and immobilize N during snowmelt, yet the population size crashes in spring, which releases a pulse of soil N. We sought to discover the N
Time-lapse imagery in 2017 and 2018 at the Lower Montane site in the East River Watershed, Colorado
Time-lapse imagery was collected using an automated RGB camera mounted on a pole at the base of the northeast-facing hillslope at the Lower Montane site in the East River Watershed, Colorado. The imagery was intended to support a better understanding of plant dynamics and their controls during the g
Metagenome-assembled genomes from topsoils along a hillslope water gradient across early snowmelt to late summer in East River, CO
Drought is changing the American Mountain West at unprecedented rates with unknown consequences to soil microbiome composition and function. As a part of LBNL Watershed Science Focus Area (SFA), we investigated shifts in microbial community and transcriptional activity on a subalpine conifer-meadow
Data and scripts from: “Denoising autoencoder for reconstructing sensor observation data and predicting evapotranspiration: noisy and missing values repair and uncertainty quantification”
This data package includes data and scripts from the manuscript “Denoising autoencoder for reconstructing sensor observation data and predicting evapotranspiration: noisy and missing values repair and uncertainty quantification”. The study addressed common challenges faced in environmental sensing a
Demographic consequences of changes in environmental periodicity
The fate of natural populations is mediated by complex interactions among vital rates, which can vary within and among years. Although the effects of random, among-year variation in vital rates have been studied extensively, relatively little is known about how periodic, nonrandom variation in vital
Virus diversity and activity is driven by snowmelt and host dynamics in a high-altitude watershed soil ecosystem
Background Viruses impact nearly all organisms on Earth, including microbial communities and their associated biogeochemical processes. In soils, highly diverse viral communities have been identified, with a global distribu‑ tion seemingly driven by multiple biotic and abiotic factors, especially so
A Meteorology and Snow Data Set From Adjacent Forested and Meadow Sites at Crested Butte, CO, USA
AbstractWe present meteorology and snow observation data collected at sites in the southwestern Colorado Rocky Mountains (USA) over three consecutive water years with different amounts of snow water equivalent (SWE) accumulation: A year with above average SWE (2019), a year with average SWE (2020),
Effects of Temperature on Voltinism in Subalpine Potter Wasps (Vespidae: Eumeninae)
Voltinism, the number of generations produced per year, is under both genetic and environmental control in insects. The rapid temperature increases associated with climate change could distort the information insects are obtaining from environmental cues and possibly alter the number of generations
The Effect of Snowmelt Timing on Pollinator Visitation to Subalpine Wildflowers
The plant and pollinator mutualism is under increased stress due to climate change, especially in subalpine ecosystems. Climate change is altering the timing of snowmelt in subalpine ecosystems, which changes the flowering phenology and possible the floral abundance of subalpine plants and therefore
The Effect of Climate Change on Soil Organic Carbon over an Elevational Gradient
Climate change will increasingly impact ecosystem functioning due to shifts in species distributions as they seek their optimal climatic conditions. Plants rely on phenotypic plasticity of leaf traits to tolerate a change in their climate. Plant leaf traits also affect the carbon cycle of the local
Intraspecific Variation in Responses of a Montane Grass, <i> Festuca thurberi </i>, to Simulated Biological Invasion
Effects of an introduced mustard, Thlaspi arvense, on soil fungal communities in subalpine meadows
Predators balance consequences of climate-change-induced habitat shifts for range-shifting and resident species
Winters are changing: snow effects on Arctic and alpine tundra ecosystems
Snow is an important driver of ecosystem processes in cold biomes. Snow accumulation determines ground temperature, light conditions, and moisture availability during winter. It also affects the growing season’s start and end, and plant access to moisture and nutrients. Here, we review the current k
Plant removal across an elevational gradient marginally reduces rates, substantially reduces variation in mineralization
The loss of aboveground plant diversity alters belowground ecosystem function; yet, the mechanisms underpinning this relationship and the degree to which plant community structure and climate mediate the effects of plant species loss remain unclear. Here, we explored how plant species loss through e
The shifting importance of abiotic and biotic factors across the life cycles of wild pollinators
Abstract Organisms living in seasonal environments are exposed to different environmental conditions as they transition from one life stage to the next across their life cycle. How different life stages respond to these varying conditions is a fundamental aspect of biology and is critical for unders
