Data from: Transgenerational and within-generation plasticity in response to climate change: insights from a manipulative field experiment across an elevational gradient
Parental environmental effects, or transgenerational plasticity, can influence an individual’s phenotype or fitness, yet remain underexplored in the context of global change. Using the perennial self-pollinating plant Boechera stricta, we explored the effects of climate change on transgenerational a
Data from: 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
Data from: Interaction rewiring and the rapid turnover of plant-pollinator networks
Whether species interactions are static or change over time has wide-reaching ecological and evolutionary consequences. However, species interaction networks are typically constructed from temporally aggregated interaction data, thereby implicitly assuming that interactions are fixed. This approach
Data from: Microenvironment and functional-trait context dependence predict alpine plant community dynamics
Predicting the structure and dynamics of communities is difficult. Approaches linking functional traits to niche boundaries, species co‐occurrence and demography are promising, but have so far had limited success. We hypothesized that predictability in community ecology could be improved by incorpor
Data from: Evidence of local adaptation to fine- and coarse-grained environmental variability in Poa alpina in the Swiss Alps
In the alpine landscape, characterized by high spatiotemporal heterogeneity and barriers, divergent selection is likely to lead to local adaptation of plant populations either through adaptive genetic differentiation or through phenotypic plasticity. The relative importance of these processes has ra
Data from: Integrating viability and fecundity selection to illuminate the adaptive nature of genetic clines
Genetically-based trait variation across environmental gradients can reflect adaptation to local environments. However, natural populations that appear well-adapted often exhibit directional, not stabilizing, selection on ecologically-relevant traits. Temporal variation in the direction of selection
Data from: Aboveground resilience to species loss but belowground resistance to nitrogen addition in a montane plant community
Data from: Aboveground resilience to species loss but belowground resistance to nitrogen addition in a montane plant community, Read, Quentin D., Henning, Jeremiah A., Classen, Aimée T., Sanders, Nathan J. Journal of Plant Ecology. DOI: 10.1093/jpe/rtx015 Data are contained in comma-separated value
Life history patterns of Ambystoma tigrinum in montane Colorado
A survey of approximately 60 ponds in the Gunnison Basin, Gunnison and Pitkin counties, Colorado, U.S.A., showed a cor- relation between the thermal ranges of the ponds and the life history pattern of Ambystoma tigrinum populations. Characterization of physical and biotic parameters allowed a rankin

Life history phenomena of <i>Ambystoma tigrinum</i> in montane Colorado
Population densities and ecological preferences of rodents in a meadow near Gothic, Colorado
A comparative study of mammalian faunal diversity and density in aspen versus meadow habitat or if you want a mouse, don't climb a tree
Population structure of pierid butterflies. I. Numbers and movements of some montane <i>Colias</i> species
Moisture Relationships in Twelve Northern Desert Shrub Communities Near Grand Junction, Colorado
P Phenological observations showed that most species occupying moist habitats continued active growth for longer periods and efficiency of water use was lower for species occupying dry habitats than for those in moist habitats.
High altitude studies of natural, supplemental and deletion of UV-B on vegetables and wheat : final report /
Decisions having great impact must be made with regard to inadvertent modification of the upper stratosphere.
The structure and genetics of a montane population of the checkerspot butterfly, <i>Chlosyne palla</i>
Aspects of circulatory physiology of montane and lowland birds
A comparison of blood values of American goldfinches during summer and winter in Michigan reveals an increase in blood characteristics of winter individuals similar in extent to that of winter pine siskins, raising the possibility that the blood parameters of high altitude birds reflect adjustments
