While community-weighted means of plant traits have been linked to mean environmental conditions at large scales, the drivers of trait variation within communities are not well understood. Local environmental heterogeneity (such as microclimate variability), in addition to mean environmental conditi

Harsh abiotic conditions such as low temperatures that lead to spring and summer frost events in high-elevation and high-latitude ecosystems can have strong negative consequences for plant growth, survival, and reproduction. Despite the predicted increase in episodic frost events under continued cli

Intraspecific variation in flower color is often attributed to pollinator-mediated selection, yet this mechanism cannot explain flower color polymorphisms in self-pollinating species. Indirect selection mediated via biotic and abiotic stresses could maintain flower color variation in these systems.

Anthropogenic climate change has already altered the timing of major life history transitions, such as the initiation of reproduction. Both phenotypic plasticity and adaptive evolution can underlie rapid phenological shifts in response to climate change but their relative contributions are poorly un

Between-individual variation in phenotypes within a population is the basis of evolution. However, evolutionary and behavioural ecologists have mainly focused on estimating between-individual variance in mean trait and neglected variation in within-individual variance, or predictability of a trait.

Altered precipitation patterns associated with anthropogenic climate change are expected to have many effects on plants and insect pollinators, but it is unknown if effects on pollination are mediated by changes in water availability. We tested the hypothesis that impacts of climate on plant pollina

Many biotic interactions influence community structure, yet most distribution models for plants have focused on plant competition or used only abiotic variables to predict plant abundance. Furthermore, biotic interactions are commonly context-dependent across abiotic gradients. For example, plant-pl

The objective of this study is to understand how climate cues affect the abundance and phenology of aphids and the arthropods with which they interact. These data were collected in 20 populations of the host plant (Ligusticum porteri) along an elevation gradient near Gothic, CO, USA. We randomly-sel

Site 5GN2404, situated on a south-facing slope overlooking the Gunnison River Valley, was examined as part of work on the Blue Mesa-Skito Transmission Line. This large scatter of flaked lithic and ground stone artifacts also includes several thermal pits (Barb Lockwood, personal communication, Augus

The Chance Gulch site, 5GN817, is an 8000 year old camp located about 2.5 miles southeast of the town of Gunnison, Colorado. The site is situated within the sagebrush community, though pine and aspen trees are within view. Nine stratigraphic samples were analyzed to determine paleovegetation and pal

Six bulk soil samples and seventeen detrital charcoal samples from sites TRCR1, TRCR2, TRCR4, TRCR5, and TRCR6 along Taylor River in Gunnison County, central Colorado, were analyzed to recover organic remains suitable for radiocarbon age determination. Samples were collected from Holocene terraces a

Data come from fourteen sites in the West Elk Mountains of Colorado, USA. The study aimed to identify the factors regulating phenology of plants and cavity-nesting insects, and to determine the likelihood of asynchrony between flowering and pollinator emergence under climate change. Numbers of flowe

This dataset involves analysis of sediment samples collected in the East River watershed and Rifle floodplain sites, CO. Samples were collected and analyzed as part of two student MS theses at Colorado School of Mines (Kenwell and Prugue) over a time period ranging from 2012 to 2015. Analyses includ

The carbon monoxide (CO) and particulate matter (PM) emissions of woodburning stoves have been measured under field conditions and the rate reductions occur because the certified stoves burn cleaner and the average burn rate of certify stoves in field use is less than the averageBurn rate of convent

ABSTRACT: The Gunnison River drains a mountainous basin in western Colorado, and is a large contributor of water to the Colorado River. As part of a study to assess water resource sensitivity to alterations in climate in the Gunnison River basin, climatic and hydrologic processes are being modeled.
