Measuring Changes in Phenology of Oklahoma Asteraceae Using Herbarium Specimens [Data set]

Abstract

This is the data set for: Unterschutez, J., Moore, A., & Messick, J. (2021). Measuring changes in phenology of Oklahoma asteraceae using herbarium specimens. Oklahoma Native Plant Record, 21. https://doi.org/10.22488/okstate.22.100002 One Read Me file explaining the formatting of the included files: read_me.txt Four data files, one each for the individual species: Grindelia_ciliata_data.txt; Liatris_punctata_data.txt; Ratibida_columnifera_data.txt; Vernonia_baldwinii_data.txt Four R scripts: Asteraceae_phenology_seasons.R: The script with the code for all analyses, with comments explaining the different parts. This script makes the plots for the initial data exploration, but they are not as polished as the plots in the paper itself (except for the boxplots, which are the same). Asteraceae_phenology_year_plots.R: The script that makes the plots for DOY versus year, with the x-axis modified for the different species that are shown in figures 5, 7, 8, and 10. Asteraceae_phenology_seasons_Grindelia_ciliata_plots.R: The script that makes the plots for the significant temperature by DOY comparisons for Peak flowering for Grindelia ciliata, shown in figure 6. Asteraceae_phenology_seasons_Ratibida_columnifera_plots.R: The script that makes the plots for the significant temperature by DOY comparisons for Peak flowering for Ratibida columnifera, shown in figure 9. Four results files, one each for the individual species: Grindelia_ciliata_results.txt; Liatris_punctata_results.txt; Ratibida_columnifera_results.txt; Vernonia_baldwinii_results.txt
