Snowpack Proportional Reduction in Growing Degree Days (2002-2021)

This is a map of the influence of snow on the energy available for plant growth (growing degree days, GDD) for the Upper Gunnison domain, derived from daily maximum temperature maps interpolated from weather station and microclimate sensor data combined with Landsat-derived estimates of the timing o

Maximum 2m Air Temperature Monthly Timeseries

These are maps of monthly averages of daily maximum air temperature for the Upper Gunnison domain measured in degrees C. Estimates were derived from weather station and microclimate sensor data using Bayesian regression-kriging, incorporating topographic and vegetation structure covariates. These da

Pre-dispersal seed predation obscures the detrimental effect of dust on wildflower reproduction - fruit data

Premise of the Research. Seed production by flowering plants depends on abiotic and biotic factors whose interacting effects may be hidden. We previously reported that exposure to dust from unpaved roads reduced the average amount of pollen on flowers of Ipomopsis aggregata, but did not consistently

Experimental test of the combined effects of water availability and flowering time on pollinator visitation and seed set

Climate change is likely to alter both flowering phenology and water availability for plants. Either of these changes alone can affect pollinator visitation and plant reproductive success. The relative impacts of phenology and water, and whether they interact in their impacts on plant reproductive s

Data from: Unraveling the ecological and evolutionary impacts of a plant invader on the pollination of a native plant

Interactions between a native plant species and its pollinators, herbivores, or microbiome can be affected by the presence of non-native plant species. Non-native plant species are altering plant-pollinator interactions, yet we know little about how these non-native species influence natural selecti

The effect of hermaphrodite density and frequency at three spatial scales on the polen receipt and seed set of gynodioecious Geranium richardsonii (Geraniaceae)

Gynodioecy is a mode of sex expression where male sterlie (hereafter female) plants and hermaphroditic plants coexist within a population. In order for the females to be maintained by natural selection, they must have experienced an increased fitness. Fitness is defined as the ability of genotype or

Plant resource allocation and herbivory for <i>Helianthella quinquenervis</i> (Asteraceae) over an elevational gradient

Resources obtained from the environment are allocated to many plant parts and functions. Resource allocation into defense, growth, and reproduction was examined for Helianthella quinquenervis, the Aspen sunflower, for three field sites over an elevational gtadient. H. quinquenervis has evolved a mut

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
