Summary

These data were compiled to investigate the evolutionary history of Astragalus iselyi, A. sabulosus var. sabulosus, and A. sabulosus var. vehiculus. The data release consists of six text files. One file is a bash script (astragalus_MLE_msms.sh) for generating simulated genetic data. Four files contain individual-level (astragalus.fasta, astragalus.nothin.recode.vcf, astragalus.recode.vcf) or population-level (astragalus_dadi.txt) information on genetic variation. One file contains sampling site-specific data for various soil and climatic variables (astragalus_env.txt). The .vcf files contain the full sequence information that is contained in the other files, but the file structures vary based on the programs used for analysis. These [...]

Purpose

The purpose of these data is to understand the history of diversification and adaptation in an Astragalus species complex (Astragalus iselyi, A. sabulosus var. sabulosus, and A. sabulosus var. vehiculus) from eastern Utah. The objectives of collecting the data were to 1) understand population structure in this species complex, 2) estimate migration rates and divergence times between populations, 3) estimate effective population sizes, 4) and understand whether natural selection has operated on genetic variation within each population. The archived data can be further used to explore the evolutionary history of these taxa and the ecological variables that shape selection. This dataset can help in understanding the number of taxonomic units within this species complex and inform conservation strategies to effectively manage them.
