Balancing selection is frequently invoked as a mechanism to maintain variation within and across populations. However, rigorous tests demonstrating balancing selection operating in nature are scarce, particularly on complex traits, which frequently display high levels of variation. Leveraging a foca

Climate change has induced pronounced shifts in the reproductive phenology of plants, yet we know little about which environmental factors contribute to interspecific variation in responses and their effects on fitness. We integrate data from a 43-year record of first flowering for six species in su

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

This file contains the data to analyze the environmental correlates of flower color variation. The results are laid out in the text (Environmental correlates of flower color variation) and Table S3.

This file contains data from transects in natural populations on individual plants. This dataset supports the section on the methods and results called "Environmental correlates of flower color variation"

This file contains the data for the no choice experiment

This file contains the data for family-level analyses of the common garden experiment.

This file contains data from the greenhouse experiment.

Fixed chromosomal inversions can reduce gene flow and promote speciation in two ways: by suppressing recombination and by carrying locally favoured alleles at multiple loci. However, it is unknown whether favoured mutations slowly accumulate on older inversions or if young inversions spread because

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

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

Identification of the causal genes that control complex trait variation remains challenging, limiting our appreciation of the evolutionary processes that influence polymorphisms in nature. We cloned a quantitative trait locus that controls plant defensive chemistry, damage by insect herbivores, surv

This file contains data on the timing of snowmelt from 1935-2012, average April-May temperatures from 1973-2011, and minimum April-May temperatures from 1973-2011. The timing of snowmelt was observed from 1975-2012, and estimated from 1935-1974 based on correlations with river runoff. Temperature da

These are data on flowering time (first flowering time and peak flowering time) for all plots from 1973-2011. Data were collected by David Inouye and collaborators. Temperature data are from the Crested Butte, CO NOAA station, and snowmelt data were collected by billy barr. The data file was created

This file contains data on flowering time (first flowering and peak flowering) from 1973-2011 averaged across all plots, as well as snowmelt data and average April-May temperature data for these years. Timing of flowering was collected by David Inouye and collaborators. Snowmelt data was collected b

This file contains the individual level data for selection analyses and estimates of response to selection in the recombinant inbred lines (RILs) planted in the Montana and Colorado parental environments. Included are data on planting site, family identification, timing of first flowering, plant siz

This file contains family-level average trait values for the recombinant inbred lines (RILs) in the Colorado garden. Columns include: family, leaf number at flowering (standardized to a mean of 0 and standard deviation of 1), height at flowering (standardized to a mean of 0 and standard deviation of

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.
