Data from: Evolution of the leaf economics spectrum in herbs: evidence from environmental divergences in leaf physiology across Helianthus (Asteraceae)
The leaf economics spectrum (LES) describes a major axis of plant functional trait variation worldwide, defining suites of leaf traits aligned with resource-acquisitive to resource-conservative ecological strategies. The LES has been interpreted to arise from leaf-level trade-offs among ecophysiolog
Data from: Deciphering the adjustment between environment and life history in annuals: lessons from a geographically-explicit approach in Arabidopsis thaliana
The role that different life-history traits may have in the process of adaptation caused by divergent selection can be assessed by using extensive collections of geographically-explicit populations. This is because adaptive phenotypic variation shifts gradually across space as a result of the geogra
Data from: Microgeographic patterns of genetic divergence and adaptation across environmental gradients in Boechera stricta (Brassicaceae)
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
Data from: Two low coverage bird genomes and a comparison of reference-guided versus de novo genome assemblies
As a greater number and diversity of high-quality vertebrate reference genomes become available, it is increasingly feasible to use these references to guide new draft assemblies for related species. Reference-guided assembly approaches may substantially increase the contiguity and completeness of a
Data from: Z chromosome divergence, polymorphism, and relative effective population size in a genus of lekking birds
Sex chromosomes contribute disproportionately to species boundaries as they diverge faster than autosomes and often have reduced diversity. Their hemizygous nature contributes to faster divergence and reduced diversity, as do some types of selection. In birds, other factors (mating system and bottle

5x consensus Sage-Grouse genome from reference-guided assembly using the Chicken genome as reference. Assembly statistics report is included.
Data from: Shifts and disruptions in resource-use trait syndromes during the evolution of herbaceous crops
Trait-based ecology predicts that evolution in high-resource agricultural environments should select for suites of traits that enable fast resource acquisition and rapid canopy closure. However, crop breeding targets specific agronomic attributes rather than broad trait syndromes. Breeding for speci
Data from: Accuracy of genomic selection models in a large population of open-pollinated families in white spruce
Genomic selection (GS) is of interest in breeding because of its potential for predicting the genetic value of individuals and increasing genetic gains per unit of time. To date, very few studies have reported empirical results of GS potential in the context of large population sizes and long breedi
Data from: Context-dependent reproductive isolation mediated by floral scent and color
Reproductive isolation due to pollinator behavior is considered a key mode of speciation in flowering plants. Although floral scent is thought to mediate pollinator behavior, little is known about its effects on pollinator attraction and floral visitation in the wild. We used field experiments with
Genetic variation within the North American Sage-grouse genus Centrocercus (class Aves)
Evaluation of genetic differentiation within the Sage-grouse genus Centrocercus. Three geographically distinct samples of North American Sage-grouse, genus Centrocercus (class Aves). Two samples are taxonomically considered Greater Sage-grouse (Centrocercus urophasianus) and the third is considered
Data from: A gain-of-function polymorphism controlling complex traits and fitness in nature
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
Data from: Strong selection genome-wide enhances fitness trade-offs across environments and episodes of selection
Fitness trade-offs across episodes of selection and environments influence life-history evolution and adaptive population divergence. Documenting these trade-offs remains challenging as selection can vary in magnitude and direction through time and space. Here, we evaluate fitness trade-offs at the
Data from: Duplication and population dynamics shape historic patterns of selection and genetic variation at the major histocompatibility complex in rodents
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
Individual level data for RILs (Recombinant Inbred Lines)
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
Family level averages for the Recombinant Inbred Lines (Colorado)
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
