Data from: Early snowmelt projected to cause population decline in a subalpine plant
How climate change influences the dynamics of plant populations is not well understood, as few plant studies have measured responses of vital rates to climatic variables and modeled the impact on population growth. I used 25 years of demographic data to analyze how survival, growth, and fecundity re
Data from: Climate change shifts natural selection and the adaptive potential of the perennial forb Boechera stricta in the Rocky Mountains
Heritable genetic variation is necessary for populations to evolve in response to anthropogenic climate change. However, antagonistic genetic correlations among traits may constrain the rate of adaptation, even if substantial genetic variation exists. We examine potential genetic responses to select
Data from: Reproductive losses due to climate change-induced earlier flowering are not the primary threat to plant population viability in a perennial herb
1. Despite a global footprint of shifts in flowering phenology in response to climate change, the reproductive consequences of these shifts are poorly understood. Furthermore, it is unknown whether altered flowering times affect plant population viability. 2. We examine whether climate change-induce
Data from: The individual and combined effects of snowmelt timing and frost exposure on the reproductive success of montane forbs
1. Changes from historic weather patterns have affected the phenology of many organisms worldwide. Altered phenology can introduce organisms to novel abiotic conditions during growth and modify species interactions, both of which could drive changes in reproduction. 2. We explored how climate change
Discharge data collected within the East River for the Lawrence Berkeley National Laboratory Watershed Function Science Focus Area (water years 2015-2018)
Discharge data collected at the East River in the Upper Colorado River Basin for the Lawrence Berkeley National Laboratory's Watershed Function Scientific Focus Area. Files contain instantaneous observed discharge data, corrected 10 min and mean daily discharge. Several sites also contain temperatur

The East River, Colorado, Watershed: A Mountainous Community Testbed for Improving Predictive Understanding of Multiscale Hydrological-Biogeochemical Dynamics: Dataset
This dataset contains snow water, precipitation, and discharge data collected from the East River watershed. This provides insight as to how the watershed works as a system and responds to hydrological perturbations.

Subalpine meadow flowering phenology responses to climate change: integrating experimental and gradient methods
We integrated experimental and natural gradient field methods to investigate effects of climate change and variability on flowering phenology of 11 subalpine meadow shrub, forb, and graminoid species in Gunnison County, Colorado (USA). At a subalpine meadow site, overhead electric radiant heaters ad
Variation in timing and abundance of flowering by <i>Delphinium barbeyi</i> Huth (Ranunculaceae): the roles of snowpack, frost, and La Niña, in the context of climate change
Power-laws and snow avalanches
This paper presents evidence of frequency‐size power‐laws in several groups of snow avalanche paths. Other natural hazards, such as earthquakes and forest fires, exhibit similar power‐law relationships. In addition, an analysis of the response of one group of snow avalanche paths to storms through t
Responses of subalpine meadow vegetation to four years of experimental warming
Ecosystems at high elevations may be especially sensitive to global warming, because productivity is limited to a snow-free growing season, and warming is expected to cause earlier snowmelt. Here we report on vegetation responses to experimental warming in a subalpine meadow in the Colorado Rocky Mo
The ecological and evolutionary significance of frost in the context of climate change
The effects that below‐freezing temperature (frost) can have at times of year when it is unusual are an interesting ecological phenomenon that has received little attention. The physiological consequence of formation of ice crystals in plant tissue is often death of the plants, or at least of sensit
