Model Scripts for "Old-Aged Groundwater Contributes to Mountain Hillslope Hydrologic Dynamics"
The partitioning of water inputs between deep and shallow groundwater flow paths is a fundamental processes, yet is challenging to observe. Numerical models provide a valuable tool to further develop insights on these groundwater mixing processes. This repository contains scripts to run the ParFlow-
Temperature, Humidity, and Time-Lapse Video Data from the East River Watershed, Water Year 2024
This dataset contains timelapse videos and distributed measurements of air temperature, relative humidity, dewpoint, and soil temperature across the East River Basin from October 3rd, 2023 to August 12th, 2024. Instruments were deployed in 14 sites as part of the DOE Grant: Seasonal Cycles Unravel M
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
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

Data from: Phylogeny does not predict the outcome of heterospecific pollen-pistil interactions in a species-rich alpine plant community
Premise: Co-occurring plant species that share generalist pollinators often exchange pollen. This heterospecific pollen transfer (HPT) impacts male and female reproductive success through pollen loss and reductions in seed set, respectively. The resulting fitness cost of HPT imposes selection on rep
Identifying the Impact of Biotic Interactions on Meadow Species Distributions in Sagebrush and Bunchgrass Dominated Systems
Understanding drivers of species distributions is an important challenge for more accurately projecting ecological change under climate warming. Species distributions have often been modeled using solely environmental factors as predictors. However, there is much recent data supporting the hypothesi
The impact of climate change on Rocky Mountain plant communities: Differences in floral trait along an elevational gradient of transplanted communities
Alpine climates are seemingly adverse environments for plants. These habitats directly impact plants via pollinator scarcity and abiotic factors like extreme temperatures and precipitation that influence resource allocation. As a result, elevational gradients are natural laboratories that can be use
Pollinator Community Compositions Across Four Subalpine Plant Species
Studies have shown that there have been pollinator declines occurring worldwide (e.g., Beismiejer et al. 2006; Potts et al. 2010; Burkle et al. 2013; Goulson et al. 2015). It is important to understand plant-pollinator interactions as thoroughly as possible, including which species are interacting w
Does the seedbank reflect the composition of the metacommunity for alpine plants?
Community ecology and dynamics are often only thought of in terms of the processes selection and speciation. Likewise, plants are often only considered in their immobile, germinated form. However, when it comes to plant community dynamics, seeds and the seedbank are often critical in predicting comm
A meta-analysis of 1,119 manipulative experiments on terrestrial carbon-cycling responses to global change
There is an urgent need to explore the interactions among multiple global change drivers in underrepresented regions such as semi-arid ecosystems, forests in the tropics and subtropics, and Arctic tundra when forecasting future terrestrial carbon-climate feedback.
The individual and combined effects of snowmelt timing and frost exposure on the reproductive success of montane forbs
Elevational cline in herbivore abundance driven by a monotonic increase in trophic level sensitivity to aridity
The abiotic environment drives species abundances and distributions both directly and indirectly through effects on multi-trophic species interactions. However, few studies have documented the individual and combined consequences of these direct and indirect effects. We studied an ant-tended aphid a
Progressive sensitivity of trophic levels to warming underlies an elevational gradient in ant–aphid mutualism strength
Although species interactions are often proposed to be stronger at lower latitudes and elevations, few studies have evaluated the mechanisms driving such patterns. In this study, we assessed whether, and by which mechanisms, abiotic changes associated with elevation altered the outcome of an ant–aph
Heterogeneity in Hyporheic Flow, Pore Water Chemistry, and Microbial Community Composition in an Alpine Streambed
AbstractThe hyporheic zone, where surface water and groundwater mix, is an important microbial habitat where biogeochemical reactions influence water quality. We show that spatial variability in hyporheic flow in the East River near Crested Butte, CO, drives heterogeneity in streambed geochemical co
Soil microbes that may accompany climate warming increase alpine plant production
Climate change is causing species with non-overlapping ranges to come in contact, and a key challenge is to predict the consequences of such species re-shuffling. Experiments on plants have focused largely on novel competitive interactions; other species interactions, such as plant–microbe symbioses
Plant Identity Influences Foliar Fungal Symbionts More Than Elevation in the Colorado Rocky Mountains
Despite colonizing nearly every plant on Earth, foliar fungal symbionts have received little attention in studies on the biogeog- raphy of host-associated microbes. Evidence from regional scale studies suggests that foliar fungal symbiont distributions are influenced both by plant hosts and environm
Altitudinal gradients fail to predict fungal symbiont responses to warming
AbstractClimate change is shifting altitudinal species ranges, with potential to disrupt species interactions. Altitudinal gradient studies and warming experiments can both increase understanding of climate effects on species interactions, but few studies have used both together to improve predictio
