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

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

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

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

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

Movement uses resources that may otherwise be allocated to somatic maintenance or reproduction. How does increased energy expenditure affect resource allocation? Using the butterfly Speyeria mormonia, we tested whether experimentally increased flight affects fecundity, lifespan or flight capacity. W

Mixed-severity fire regimes may be the most extensive yet poorly understood fire regimes of western North America. Understanding their long-term spatiotemporal dynamics is central to debates regarding altered fire regimes and the need for restoration in the context of changing climate and nearly a c

This file contains data on the frost damage of eight subalpine plant species from the Rocky Mountains of Colorado (USA). These frost damage data can be used to calculate frost sensitivity for each species. Frost damage of plant tissue was determined after specimen were exposed to experimental temper

Abiotic and biotic conditions often vary continuously across the landscape, imposing divergent selection on local populations. We used a provenance trial approach to examine microgeographic variation in local adaptation in Boechera stricta (Brassicaceae), a perennial forb native to the Rocky Mountai

FASTA file of 21 MHC Class II Mimo-DRB alleles recovered from a wild population of montane vole (Microtus montanus). Samples were obtained between 2008-2010 near the Rocky Mountain biological Laboratory, located in the Upper East River Valley, CO (39N, 107W).

Genetic variation at the MHC is vitally important for wildlife populations to respond to pathogen threats. Because natural populations can fluctuate greatly in size, a key issue concerns how population cycles and bottlenecks that could reduce genetic diversity will influence MHC genes. Using 454 seq

This file contains phenotypic and fitness data on naturally-recruiting Boechera stricta plants in 5 transects. Jill Anderson collected these data at the Carpenter Meadow site in 2010. The data file was created in Text Wrangler.
