ParFlow-CLM model simulation files for Maina et al., Journal of Hydrology, 2022
This dataset contains the files to run a ParFlow-CLM integrated hydrologic model simulation for Maina et al., HESS, 2022. It also contains the associated daily pressure output of those simulations. Simulations are for a hillslope-similarity approach based on seasonal groundwater changes in the East

Sulfur x-ray absorption spectroscopy data from bedrock shale, soil, and floodplain sediment from the East River, Colorado watershed.
This dataset includes sulfur x-ray absorption near edge spectroscopy (XANES) data collected on solid samples as a part of the Watershed Function Scientific Focus Area (SFA) located in the Upper Colorado River Basin. The data were collected in order to investigate the speciation of sulfur and degree
Stable isotopes of carbon dioxide (CO2), dissolved inorganic carbon (DIC), water and concentrations of greenhouse gases in a mountainous watershed (Crested Butte, Colorado).
Temperature and precipitation variability in response to climate change affects water cycling of watersheds and can potentially impact water quality, water availability, elemental and molecular fluxes, and biogeochemical processes. Here we report the measurements of light stable isotopes and greenho
Multisensory perception in uncertain environments
Animals must use cues from smells, sounds, and sights to reduce uncertainty about the environment. Despite the ecological relevance of multisensory perception in helping animals cope with uncertainty, empirical support from natural systems is rarely placed within an adaptive framework. The field of
Litter sex composition affects life-history traits in yellow-bellied marmots
Stochastic population dynamics of a montane ground-dwelling squirrel
Understanding the causes and consequences of population fluctuations is a central goal of ecology. We used demographic data from a long-term (1990–2008) study and matrix population models to investigate factors and processes influencing the dynamics and persistence of a golden-mantled ground squirre
The indirect consequences of a mutualism: comparing positive and negative components of the net interaction between honeydew-tending ants and host plants
Large-scale manipulation of mayfly recruitment affects population size
Plot-scale evidence of tundra vegetation change and links to recent summer warming
Global assessment of experimental Climate warming on tundra vegetation: heterogeneity over space and time
Sarah C. Elmendorf,1* Gregory H. R. Understanding the sensitivity of tundra vegetation to climate warming is critical to forecasting future Henry,1 Robert D. Hollister,2 Robert G. biodiversity and vegetation feedbacks to climate. In situ warming experiments accelerate climate change on a Björk,3 An
Forecasting phenology: from species variability to community forecasts
The shape of a species\\\' spatial abundance distribution
ABSTRACTAim The shape of a species' spatial abundance distribution may change with spatial scale. We predict that the shape will typically change from strictly downward‐sloping (falling) to humped (rising then falling) as the spatial scale increases. The prediction, motivated in part by central limi
Effects of altitude on co-flowering phenology in a montane wildflower community
Phenology is an important life history trait. As altitude increases in alpine environments, the growing season shortens and flowering phenology is more compressed. Co-flowering could occur more at higher elevations as a compensation for the shorter growing season. However, interspecific competition
Impact of mound-building ants on ecosystem properties create islands of fertility in alpine meadows
Effects of species composition change under experimental warming on soil microclimate in a montane meadow
The results of a long-term experimental warming study, in a montane meadow in the Rocky Mountains of Colorado, have shown that Artemisia tridentata (Common Sagebrush) is likely to increase in abundance under climate change, as perennial forb species decrease in abundance. This change in species comp
