Local adaptation to climate has facilitated the global invasion of cheatgrass

Data and code for Local adaptation to climate facilitates a global invasion.

Bromus_tectorum_growth_chamber_phenotypes: contains individual-level growth chamber phenotype data. Columns are phenotypes as described in the manuscript methods (with corresponding units).

Bromus_tectorum_common_gardens_data: contains individual-level flowering time and fitness data for 2 replicated common gardens across 2 years + metadata explaining column names.

angsd2vcf_workflow.sh: contains examples of the code used to analyze next generation sequencing (NGS) data; from mapped (bam) files to the final imputed variant call format (vcf) used for subsequent analyses. Subsequent analyses can be reproduced using the procedures described in the manuscript methods and supplementary methods.

Bromus_tectorum_genomic_data: contains genomic files with genotype likelihoods (beagle.gz) used for NGSadmix and PCAngsd, SNP calls used for GWAS (filtered.vcf.gz and filtered.gds), and SNP calls used for other population genetic structure analyses (LDfiltered.vcf.gz and LDfiltered.gds). To unarchive this folder use: tar -xzvf Bromus_tectorum_genomic_data.tar.gz

GeneticGeographicClimateDistance: contains estimated genetic (dissimilarity and shared fraction of genome-wide SNP alleles), geographic (km), and climatic distances (Euclidian, based on PC1 and PC2 of 52 CHELSA climate variables) for native and invaded pairs of genotypes. Also for pairs of genotypes from eastern North America (ENA), western North America (WNA), NCE Europe, Mediterranean, and W Asia.
